omapdss_find_dss_of_node() calls of_find_compatible_node() to get device
node. of_find_compatible_node() returns a node pointer with refcount
incremented, we should use of_node_put() on it when done.
Add missing of_node_put() in later error path and normal path.

This series has been 12 years in the making, it mostly finishes the
work that was started with the founding of Linaro to clean up platform
support in the kernel.
The largest change here is a cleanup of the omap1 platform, which
is the final ARM machine type to get converted to the common-clk
subsystem. All the omap1 specific drivers are now made independent of the
mach/*.h headers to allow the platform to be part of a generic ARMv4/v5
multiplatform kernel. The last bit that enables this support is still
missing here while we wait for some last dependencies to make it into
the mainline kernel through other subsystems.
The s3c24xx, ixp4xx, iop32x, ep93xx and dove platforms were all almost
at the point of allowing multiplatform kernels, this work gets completed
here along with a few additional cleanup. At the same time, the s3c24xx
and s3c64xx are now deprecated and expected to get removed in the future.
The PXA and OMAP1 bits are in a separate branch because of dependencies.
Once both branches are merged, only the three Intel StrongARM platforms
(RiscPC, Footbridge/NetWinder and StrongARM1100) need separate kernels,
and there are no plans to include these.

Commit 9c46929e79 ("ARM: implement THREAD_INFO_IN_TASK for uniprocessor
systems") started triggering an issue with smc calls hanging on boot as
VMAP_STACK is now enabled by default.
Based on discussions on the #armlinux irc channel, Arnd noticed that omaps
are using __pa() for stack for smc calls. This does not work with vmap
stack.
Let's fix the issue by changing the param arrays to use static param[5] for
each function for __pa() to work. This consumes a bit more memory compared
to adding a single static buffer, but avoids potential races with the smc
calls initializing the shared buffer. For omap_secure_dispatcher(), we need
to use a cpu specific buffer as there's nothing currently ensuring it only
gets called from cpu0.

including the correspondig device tree bindings:
- A couple of reset controller changes for unisoc, uniphier, renesas
and zte platforms
- memory controller driver fixes for omap and tegra
- Rockchip io domain driver updates
- Lots of updates for qualcomm platforms, mostly touching their
firmware and power management drivers
- Tegra FUSE and firmware driver updateѕ
- Support for virtio transports in the SCMI firmware framework
- cleanup of ixp4xx drivers, towards enabling multiplatform
support and bringing it up to date with modern platforms
- Minor updates for keystone, mediatek, omap, renesas.

There are three noteworthy updates for 32-bit arm platforms this time:
- The Microchip SAMA7 family based on Cortex-A7 gets introduced, a new
cousin to the older SAM9 (ARM9xx based) and SAMA5 (Cortex-A5 based)
SoCs.
- The ixp4xx platform (based on Intel XScale) is finally converted to
device tree, and all the old board files are getting removed now.
- The Cirrus Logic EP93xx platform loses support for the old
MaverickCrunch FPU. Support for compiling user space applications
was already removed in gcc-4.9, and the kernel support for old
applications could not be built with clang ias. After confirming
that there are no remaining users, removing this from the kernel
seemed better than adding support for unused features to clang.
There are minor updates to the aspeed, omap and samsung platforms

We can now switch over to using cpu_pm instead of custom calls and make

Let's also move the save and restore functions to avoid adding forward

If the PM related modules are not loaded and PM firmware not configured,
the system suspend fails to resume. Let's fix this by adding initial
platform_suspend_ops to block suspend and warn about missing modules.
When pm33xx and wkup_m3_ipc have been loaded and m3 coprocessor booted
with it's firmware, pm33xx sets up working platform_suspend_ops. Note
that we need to configure at least PM_SUSPEND_STANDBY to have
suspend_set_ops().

The opening comment mark '/**' is used for highlighting the beginning of
kernel-doc comments.
The header for arch/arm/mach-omap2/omap_twl.c follows this syntax, but the
content inside does not comply with kernel-doc.
This line was probably not meant for kernel-doc parsing, but is parsed
due to the presence of kernel-doc like comment syntax(i.e, '/**'), which
causes unexpected warning from kernel-doc:
"warning: wrong kernel-doc identifier on line:
* OMAP and TWL PMIC specific initializations."
Provide a simple fix by replacing this occurrence with general comment
format, i.e. '/*', to prevent kernel-doc from parsing it.

We need to add a dummy smc call to the cpuidle wakeup path to force the
ROM code to save the return address after MMU is enabled again. This is
needed to prevent random hangs on secure devices like droid4.
Otherwise the system will eventually hang when entering deeper SoC idle
states with the core and mpu domains in open-switch retention (OSWR).
The hang happens as the ROM code tries to use the earlier physical return
address set by omap-headsmp.S with MMU off while waking up CPU1 again.
The hangs started happening in theory already with commit caf8c87d7f
("ARM: OMAP2+: Allow core oswr for omap4"), but in practise the issue went
unnoticed as various drivers were often blocking any deeper idle states
with hardware autoidle features.
This patch is based on an earlier TI Linux kernel tree commit 92f0b3028d9e
("OMAP4: PM: update ROM return address for OSWR and OFF") written by
Carlos Leija <cileija@ti.com>, Praneeth Bajjuri <praneeth@ti.com>, and
Bryan Buckley <bryan.buckley@ti.com>. A later version of the patch was
updated to use CPU_PM notifiers by Tero Kristo <t-kristo@ti.com>.

When I dropped legacy data for omap4 and dra7 smartreflex in favor of
device tree based data, it seems I only testd for the "SmartReflex Class3
initialized" line in dmesg. I missed the fact that there is also
omap_devinit_smartreflex() that happens later, and now it produces an
error on boot for "No Voltage table for the corresponding vdd. Cannot
create debugfs entries for n-values".
This happens as we no longer have the smartreflex instance legacy data,
and have not yet moved completely to device tree based booting for the
driver. Let's fix the issue by changing the smartreflex init to use names.
This should all eventually go away in favor of doing the init in the
driver based on devicetree compatible value.
Note that dra7xx_init_early() is not calling any voltage domain init like
omap54xx_voltagedomains_init(), or a dra7 specific voltagedomains init.
This means that on dra7 smartreflex is still not fully initialized, and
also seems to be missing the related devicetree nodes.

After converting am335x to probe devices with simple-pm-bus I noticed
that we are not passing auxdata for of_platform_populate() like we do
with simple-bus.
While device tree using SoCs should no longer need platform data, there
are still quite a few drivers that still need it as can be seen with
git grep OF_DEV_AUXDATA. We want to have simple-pm-bus be usable as a
replacement for simple-bus also for cases where OF_DEV_AUXDATA is still
needed.
Let's fix the issue by passing auxdata as platform data to simple-pm-bus.
That way the SoCs needing this can pass the auxdata with OF_DEV_AUXDATA.
And let's pass the auxdata for omaps to fix the issue for am335x.
As an alternative solution, adding simple-pm-bus handling directly to
drivers/of/platform.c was considered, but we would still need simple-pm-bus
device driver. So passing auxdata as platform data seems like the simplest
solution.

We now depend on SIMPLE_PM_BUS for probing devices. While we have it
selected in omap2plus_defconfig, custom configs can fail if it's missing.
As SIMPLE_PM_BUS depends on OF and PM, we must now select PM in Kconfig.
We have already OF selected by ARCH_MULTIPLATFORM.

We get suspcious RCU usage splats with cpuidle in several places in
omap_enter_idle_coupled() with the kernel debug options enabled:
RCU used illegally from extended quiescent state!
...
(_raw_spin_lock_irqsave)
(omap_enter_idle_coupled+0x17c/0x2d8)
(omap_enter_idle_coupled)
(cpuidle_enter_state)
(cpuidle_enter_state_coupled)
(cpuidle_enter)
Let's use RCU_NONIDLE to suppress these splats. Things got changed around
with commit 1098582a0f ("sched,idle,rcu: Push rcu_idle deeper into the
idle path") that started triggering these warnings.
For the tick_broadcast related calls, ideally we'd just switch over to
using CPUIDLE_FLAG_TIMER_STOP for omap_enter_idle_coupled() to have the
generic cpuidle code handle the tick_broadcast related calls for us and
then just drop the tick_broadcast calls here.
But we're currently missing the call in the common cpuidle code for
tick_broadcast_enable() that CPU1 hotplug needs as described in earlier
commit 50d6b3cf94 ("ARM: OMAP2+: fix lack of timer interrupts on CPU1
after hotplug").

These are a small number of bug fixes that all came in before or during
the merge window, most for the omap platform:
- One boot regression fix for Nokia N9 (OMAP3).
- Two small defconfig changes for omap2, to reflect changes in drivers
- Warning fixes for DT issues on omap2, picoxcell and bitmap SoCs.
The picoxcell platform will be removed in v5.12, but fixing it
first makes it easier to backport to the fix to stable kernels
and get a clean build with new dtc versions

Merge tag 'arm-fixes-5.11-1' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc
Pull ARM SoC fixes from Arnd Bergmann:
"These are a small number of bug fixes that all came in before or
during the merge window, most for the omap platform:
- One boot regression fix for Nokia N9 (OMAP3).
- Two small defconfig changes for omap2, to reflect changes in
drivers
- Warning fixes for DT issues on omap2, picoxcell and bitmap SoCs.
The picoxcell platform will be removed in v5.12, but fixing it
first makes it easier to backport to the fix to stable kernels and
get a clean build with new dtc versions"
* tag 'arm-fixes-5.11-1' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc:
ARM: picoxcell: fix missing interrupt-parent properties
ARM: dts: ux500/golden: Set display max brightness
arm64: dts: bitmain: Use generic "ngpios" rather than "snps,nr-gpios"
ARM: omap2: pmic-cpcap: fix maximum voltage to be consistent with defaults on xt875
ARM: omap2plus_defconfig: enable SPI GPIO
ARM: OMAP2+: omap_device: fix idling of devices during probe
ARM: dts: OMAP3: disable AES on N950/N9
ARM: omap2plus_defconfig: drop unused POWER_AVS option
These are additional updates for the power domain support on OMAP,
moving to an implementation based on device tree information instead of
SoC specific code. This is the latest step in the ongoing process for
moving code out of arch/arm/mach-omap2.
I kept this separate from the other driver changes since it touches
code in multiple areas.
There is one conflict in the dra7.dts file, which adds another node
in a different branch. Watch out for adding the trailing '};'
both times.

There are a couple of subsystems maintained by other people that
merge their drivers through the SoC tree, those changes include:
- The SCMI firmware framework gains support for sensor notifications
and for controlling voltage domains.
- A large update for the Tegra memory controller driver, integrating
it better with the interconnect framework
- The memory controller subsystem gains support for Mediatek MT8192
- The reset controller framework gains support for sharing pulsed
resets
For Soc specific drivers in drivers/soc, the main changes are
- The Allwinner/sunxi MBUS gets a rework for the way it handles
dma_map_ops and offsets between physical and dma address spaces.
- An errata fix plus some cleanups for Freescale Layerscape SoCs
- A cleanup for renesas drivers regarding MMIO accesses.
- New SoC specific drivers for Mediatek MT8192 and MT8183 power domains
- New SoC specific drivers for Aspeed AST2600 LPC bus control
and SoC identification.
- Core Power Domain support for Qualcomm MSM8916, MSM8939, SDM660
and SDX55.
- A rework of the TI AM33xx 'genpd' power domain support to use
information from DT instead of platform data
- Support for TI AM64x SoCs
- Allow building some Amlogic drivers as modules instead of built-in
Finally, there are numerous cleanups and smaller bug fixes for
Mediatek, Tegra, Samsung, Qualcomm, TI OMAP, Amlogic, Rockchips,
Renesas, and Xilinx SoCs.

ARM is the only architecture that defines CONFIG_ARCH_HAS_HOLES_MEMORYMODEL
which in turn enables memmap_valid_within() function that is intended to
verify existence of struct page associated with a pfn when there are holes
in the memory map.
However, the ARCH_HAS_HOLES_MEMORYMODEL also enables HAVE_ARCH_PFN_VALID
and arch-specific pfn_valid() implementation that also deals with the holes
in the memory map.
The only two users of memmap_valid_within() call this function after
a call to pfn_valid() so the memmap_valid_within() check becomes redundant.
Remove CONFIG_ARCH_HAS_HOLES_MEMORYMODEL and memmap_valid_within() and rely
entirely on ARM's implementation of pfn_valid() that is now enabled
unconditionally.

On the GTA04A5 od->_driver_status was not set to BUS_NOTIFY_BIND_DRIVER
during probe of the second mmc used for wifi. Therefore
omap_device_late_idle idled the device during probing causing oopses when
accessing the registers.
It was not set because od->_state was set to OMAP_DEVICE_STATE_IDLE
in the notifier callback. Therefore set od->_driver_status also in that
case.
This came apparent after commit 21b2cec61c ("mmc: Set

To drop the legacy platform data for am3 control module, we need
to configure the missing functional clock and tag the module to

If we have no hwmods configured and omap_hwmod_init() is not called,
we don't want to call omap_hwmod_setup_all() as it will fail with

Based on more testing, commit 8ca5ee624b4c ("ARM: OMAP2+: Restore MPU
power domain if cpu_cluster_pm_enter() fails") is a poor fix for handling
cpu_cluster_pm_enter() returned errors.
We should not override the cpuidle states with a hardcoded PWRDM_POWER_ON
value. Instead, we should use a configured idle state that does not cause
the context to be lost. Otherwise we end up configuring a potentially
improper state for the MPUSS. We also want to update the returned state
index for the selected state.
Let's just select the highest power idle state C1 to ensure no context
loss is allowed on cpu_cluster_pm_enter() errors. With these changes we
can now unconditionally call omap4_enter_lowpower() for WFI like we did
earlier before commit 55be2f5033 ("ARM: OMAP2+: Handle errors for
cpu_pm"). And we can return the selected state index.

SoC changes, a substantial part of this is cleanup of some of the older
platforms that used to have a bunch of board files. In particular:
- Removal of non-DT i.MX platforms that haven't seen activity in years,
it's time to remove them.
- A bunch of cleanup and removal of platform data for TI/OMAP platforms,
moving over to genpd for power/reset control (yay!)
- Major cleanup of Samsung S3C24xx and S3C64xx platforms, moving them
closer to multiplatform support (not quite there yet, but getting
close).
THere are a few other changes too, smaller fixlets, etc. For new
platform support, the primary ones re:
- New SoC: Hisilicon SD5203, ARM926EJ-S platform.
- Cpufreq support for i.MX7ULP

Enabling off mode was only reachable deeply hidden
in the debugfs. As powersaving is an important feature,
move the option out of its shady place.
The debugfs file can still be used to override the default.
