Due to the fact that Lenovo Thinkpad T14s Gen6 is available with both
OLED and LCD, the backlight control differs HW-wise. For the LCD variant,
the panel's backlight is controlled via one of the PWMs provided by the
PMK8550 PMIC. For the OLED variant, the backlight is internal to the
panel and therefore it is not described in devicetree.
For this reason, create a generic dtsi for the T14s by renaming the
existing dts. While at it, add a node name to panel and drop the enable
gpio and pinctrl properties from the panel node. Then add the LCD variant
dts file with the old name and describe all backlight related nodes.
So the existing dts will now be used for LCD variant while for OLED new
dts will be added.

The Lenovo ThinkPad T14s Gen6 provides external DisplayPort on all
2 USB Type-C ports. Each one of this ports is connected to a dedicated
DisplayPort controller.
Due to support missing in the USB/DisplayPort combo PHY driver,
the external DisplayPort is limited to 2 lanes.
So enable the first and second DisplayPort controllers and limit their
data lanes number to 2.

The Lenovo ThinkPad T14s Gen6 laptop comes with 3 Parade PS8830 retimers,
one for each Type-C port. These handle the orientation and altmode
switching and are controlled over I2C. In the connection chain, they sit
between the USB/DisplayPort combo PHY and the Type-C connector.
Describe the retimers and all gpio controlled voltage regulators used by
each retimer. Also, modify the pmic glink graph to include the retimers in
between the SuperSpeed/Sideband in endpoints and the QMP PHY out
endpoints.

We see the addition of eleven new SoCs, including a total of sixx arm64
chips from Qualcomm alone. Overall, the Qualcomm platforms once again
make up the majority of all changes, after a couple of quieter releases.
The new SoCs in this branch are:
- Microchip sama7d65 is a new 32-bit embedded chip with a single
Cortex-A7 and the current high end of the old Atmel SoC line.
- Samsung Exynos 9810 is a mobile phone chip used in some older
phones like the Samsung Galaxy S9
- Renesas R-Car V4H ES3.0 (R8A779G3) is an updated version of
the V4H (R8A779G0) low-power automotive SoC
- Renesas RZ/G3E (R0A09G047) is a family of embedded chips
using Cortex-A55 cores
- Qualcomm Snapdragon 8 Elite (SM8750) is a new phone chip based on
Qualcomm's Oryon CPU cores.
- Qualcomm Snapdragon AR2 (SAR2130P) is a SoC for augmented reality
glasses.
- Qualcomm IQ6 (QCS610) and IQ8 (QCS8300) are two industrial
IOT platforms.
- Snapdragon 425 (MSM8917) is a mobile phone SoC from 2016
- Qualcomm IPQ5424 is a Wi-Fi 7 networking chip
All of the above are part of already supported SoC families that
only need new devicetree files. Two additional SoCs in new
families are part of a separate branch.
There are 48 new machines in total, including six arm32 ones based
on aspeed. broadcom, microchip and st SoCs all using Cortex-A7 cores,
and a single risc-v board, the Banana Pi R3.
The remaining ones use arm64 chips from Broadcom, Samsung, NXP, Mediatek,
Qualcomm, Renesas and Rockchips and cover development boards, phones,
laptops, industrial machines routers.
A lot of ongoing work is for cleaning up build time warnings and other
issues, in addition to the new machines and added features.

On Lenovo ThinkPad T14s, the fingerprint reader placed in the power
button is connected via the usb_2 controller. The controller has only
a USB 2.0 PHY which is then connected via a NXP PTN3222 eUSB2 repeater,
which in turn is connected to the Goodix fingerprint reader.
So enable all the usb_2 controller and PHY nodes, set dual-role mode to

enumerated, but the device is not:
xhci-hcd xhci-hcd.5.auto: xHCI Host Controller

Once this happens on either of the two ports, no amount of disconnecting
and reconnecting makes the SuperSpeed device be enumerated, while
FullSpeed device enumeration still works.
With retimer (and orientation detection) support not even merged yet,
let's revert at least until we have stable host mode in mainline.

At the moment, x1e80100-pmics.dtsi enables two of the SMB2360 PMICs by
default and leaves the other two disabled. The third one was originally
also enabled by default, but then disabled in commit a237b8da41 ("arm64:
dts: qcom: x1e80100: Disable SMB2360_2 by default"). This is inconsistent
and confusing. Some laptops will even need SMB2360_1 disabled by default if
they just have a single USB-C port.
Make this consistent by keeping all SMB2360 disabled in x1e80100-pmics.dtsi
and enable them separately for all boards where needed. That way it is
always clear which ones are available and avoids accidentally trying to
read/write from missing chips when some of the PMICs are not present.

This release adds the devicetree files for an impressive number of new
SoC variants, though as expected these are all related to others we
already support:
- The microchip sam9x7 devicetree is now added, after the device driver
and platform code has already made it in. This is likely the last ARMv5
(!) platform to ever get added, updating the 20+ year old at91/sam9
platform wtih DDR3 memory and gigabit ethernet.
- On the Apple platform, there are now devicetree files for a number of
A-series SoCs in addition to the M-series ones, these are used
primarily in phones and tablets, but are closely related to the
already supported chips.
- Samsung Exynos 8895 and Exynos 990 are more phone SoCs used in older
Samsung Galaxy phones.
- Qualcomm Snapdragon 778G (SM7325) is another phone SoC, closely related
to the Snapdragon 7c+ Gen 3 (SC7280) used in low-end laptops.
- Rockchip RK3528 and RK3576 are new variants of their TV box and Tablet
chips, still using the older ARMv8.0 cores from RK3328/RK3399 but
with a newer process and other improvements from the RK35xx (otherwise
ARMv8.2) chips. RK3566T and RK3399-S are also added, these are just
lower-cost versions of their normal counterparts.
- TI J742S2 is a feature-reduced version of the J784s4
industrial/automotive SoC, with fewer CPU cores.
- Sophgo SG2002 is an embedded SoC with one RISC-V (C906) and one ARM
(Cortex-A53) core, at this point support is only added for running
on the RISC-V side on the LicheeRV Nano board.
A total of 92 new .dts files describing individual machines is added,
which must be a new record. The majority of these is for the newly added
chips above, notably all the Apple phones and tablets. The other new
machines include nine industrial/embedded boards with NXP i.MX6 or i.MX8
SoCs, eight for Rockchips RK35XX and one or two each for Rockchips RV1109,
RK3308, Allwinner A33, Tegra 234, Qualcomm qcs9100/sc8280xp/x1e80100,
TI AM625 and Starfive JH7110.
As usual there are also many newlyad added features in existing boards
as well as cleanups and minor bugfixes.

Trackpad HID device on T14s could be found on two possible slave addresses
(hid@15 and hid@2c) on i2c0 instance.
With the current state of DT boot, there is no way to patch the device
tree at runtime during boot. This, however results in non-functional
trackpad on Product Models 21N2ZC5PUS which have trackpad on hid@2c
slave address.
This patch adds hid@2c device along with hid@15 to get it working on
both the variants. This should work as i2c-hid driver will stop
probing the device if there is nothing on the slave address, we can
actually keep both devices enabled in DT, and i2c-hid driver will
only probe the existing one.
The only problem is that we cannot setup pinctrl in both device nodes,
as two devices with the same pinctrl will cause pin conflict that makes
the second device fail to probe. Let's move the pinctrl state up to
parent node along with the parent pinctrl to solve this problem.
