The conversion of all GPIO drivers to using the .set_rv() and
.set_multiple_rv() callbacks from struct gpio_chip (which - unlike their
predecessors - return an integer and allow the controller drivers to
indicate failures to users) is now complete and the legacy ones have
been removed. Rename the new callbacks back to their original names in
one sweeping change.

In some Amlogic SoCs, to save register space or due to some
abnormal arrangements, two sets of pins share one mux register.
A group starting from pin0 is the main pin group, which acquires
the register address through DTS and has management permissions,
but the register bit offset is undetermined.
Another GPIO group as a subordinate group. Some pins mux use share
register and bit offset from bit0 . But this group do not have
register management permissions.
This submission implements this situation.

The public datasheets of the following Amlogic SoCs describe a typical
resistor value for the built-in pull up/down resistor:
- Meson8/8b/8m2: not documented
- GXBB (S905): 60 kOhm
- GXL (S905X): 60 kOhm
- GXM (S912): 60 kOhm
- G12B (S922X): 60 kOhm
- SM1 (S905D3): 60 kOhm
The public G12B and SM1 datasheets additionally state min and max
values:
- min value: 50 kOhm for both, pull-up and pull-down
- max value for the pull-up: 70 kOhm
- max value for the pull-down: 130 kOhm
Use 60 kOhm in the pinctrl-meson driver as well so it's shown in the
debugfs output. It may not be accurate for Meson8/8b/8m2 but in reality
60 kOhm is closer to the actual value than 1 Ohm.

As part of that merge prepping Arm DT support 13 years ago, they
"temporarily" include each other. They also include platform_device.h

If a GPIO bank has greater than 16 pins, PAD_DS_REG is split into two
or more registers. However, when register and bit were calculated, the
first register defined in the bank was used, and the bit was calculated
based on the first pin. This causes problems in setting the driving
strength.
The following method was used to solve this problem:
A bit is calculated first using predefined strides. Then, If the bit is
32 or more, the register is changed by the quotient of the bit divided
by 32. And the bit is set to the remainder.

GPIOH_5 and GPIOH_6 can have two Ethernet related functions:
- GPIOH_5 can be ETH_TXD1 or ETH_RXD3
- GPIOH_6 can be ETH_TXD0 or ETH_RXD2
Add the bits for eth_rxd3_h and eth_rxd2_h so the ETH_RXD function can
be disabled when using the ETH_TXD function of GPIOH_{5,6}. No problem
was observed so far, but in theory this could lead to two different
signals being routed to the same pad (which could break Ethernet).

In meson_pinconf_get_drive_strength, variable bit is calculated by
meson_calc_reg_and_bit, this value is the offset from the first pin of a
certain bank to current pin, while Meson SoCs use two bits for each pin
to depict drive-strength. So a left shift by 1 should be done or node
pinconf-pins shows wrong message.

Meson A1 SoC share the same register layout of pinmux with previous
Meson-G12A, however there is difference for gpio and pin config register
in A1. The main difference is that registers before A1 are grouped by
function while those of A1 are by bank. The new register layout is as
below:
/* first bank */ /* addr */
- P_PADCTRL_GPIOP_I base + 0x00 << 2
- P_PADCTRL_GPIOP_O base + 0x01 << 2
- P_PADCTRL_GPIOP_OEN base + 0x02 << 2
- P_PADCTRL_GPIOP_PULL_EN base + 0x03 << 2
- P_PADCTRL_GPIOP_PULL_UP base + 0x04 << 2
- P_PADCTRL_GPIOP_DS base + 0x05 << 2
/* second bank */
- P_PADCTRL_GPIOB_I base + 0x10 << 2
- P_PADCTRL_GPIOB_O base + 0x11 << 2
- P_PADCTRL_GPIOB_OEN base + 0x12 << 2
- P_PADCTRL_GPIOB_PULL_EN base + 0x13 << 2
- P_PADCTRL_GPIOB_PULL_UP base + 0x14 << 2
- P_PADCTRL_GPIOB_DS base + 0x15 << 2
Each bank contains at least 6 registers to be configured, if one bank
has more than 16 gpios, an extra P_PADCTRL_GPIO[X]_DS_EXT is included.
Between two adjacent P_PADCTRL_GPIO[X]_I, there is an offset 0x10, that
is to say, for third bank, the offsets will be 0x20,0x21,0x22,0x23,0x24
,0x25 according to above register layout. For previous chips, registers
are grouped according to their functions while registers of A1 are
according to bank.Also note that there is no AO bank any more in A1.
Current Meson pinctrl driver can cover such change by using base address
of GPIO as that of drive-strength. While simply giving reg_ds = reg_pullen
make wrong value to reg_ds for Socs that do not support drive-strength
like AXG.To make things simple, add an extra dt parser function for
a1 and remain the old dt parser function for only reg parsing.

In meson_pinctrl_parse_dt, it contains two parts: reg parsing and
SoC relative fixup for AO. Several fixups in the same code make it hard
to maintain, so move all fixups to each SoC's callback and make
meson_pinctrl_parse_dt just do the reg parsing, separate these two
parts.Overview of all current Meson SoCs fixup is as below:
+------+--------------------------------------+--------------------------+
| | | |
| SoC | EE domain | AO domain |
+------+--------------------------------------+--------------------------+
|m8 | parse regs: | parse regs: |
|m8b | gpio,mux,pull,pull-enable(skip ds) | gpio,mux,pull(skip ds)|
|gxl | fixup: | fixup: |
|gxbb | no | pull-enable = pull; |
|axg | | |
+------+--------------------------------------+--------------------------+
|g12a | parse regs: | parse regs: |
|sm1 | gpio,mux,pull,pull-enable,ds | gpio,mux,ds |
| | fixup: | fixup: |
| | no | pull = gpio; |
| | | pull-enable = gpio; |
+------+--------------------------------------+--------------------------+
|a1 or | parse regs: |
|later | gpio/mux (without ao domain) |
|SoCs | fixup: |
| | pull = gpio; pull-enable = gpio; ds = gpio; |
+------+-----------------------------------------------------------------+
Since m8-axg share the same ao fixup, make a common function
meson8_aobus_parse_dt_extra to do the job.

cycle:
Core changes:
- Device links can optionally be added between a pin control
producer and its consumers. This will affect how the system
power management is handled: a pin controller will not suspend
before all of its consumers have been suspended. This was
necessary for the ST Microelectronics STMFX expander and
need to be tested on other systems as well: it makes sense
to make this default in the long run. Right now it is
opt-in per driver.
- Drive strength can be specified in microamps. With decreases
in silicon technology, milliamps isn't granular enough, let's
make it possible to select drive strengths in microamps. Right
now the Meson (AMlogic) driver needs this.
New drivers:
- New subdriver for the Tegra 194 SoC.
- New subdriver for the Qualcomm SDM845.
- New subdriver for the Qualcomm SM8150.
- New subdriver for the Freescale i.MX8MN (Freescale is now a
product line of NXP).
- New subdriver for Marvell MV98DX1135.
Driver improvements:
- The Bitmain BM1880 driver now supports pin config in
addition to muxing.
- The Qualcomm drivers can now reserve some GPIOs as taken
aside and not usable for users. This is used in ACPI systems
to take out some GPIO lines used by the BIOS so that
noone else (neither kernel nor userspace) will play with them
by mistake and crash the machine.
- A slew of refurbishing around the Aspeed drivers (board
management controllers for servers) in preparation for the
new Aspeed AST2600 SoC.
- A slew of improvements over the SH PFC drivers as usual.
- Misc cleanups and fixes.
