43c95d3694 This is the bulk of pin control changes for the v5.3 kernel
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.

Fix the mismatch between the "sdxc_d13_1_a" pin group definition from
meson8b_cbus_groups and the entry in sdxc_a_groups ("sdxc_d0_13_1_a").
This makes it possible to use "sdxc_d13_1_a" in device-tree files to
route the MMC data 1..3 pins to GPIOX_1..3.

e66dd48e8b pinctrl: meson: fix G12A ao pull registers base address
Since Meson G12A SoC, Introduce new ao registers AO_RTI_PULL_UP_EN_REG
and AO_GPIO_O.

These bits of controlling output level are remapped to the new register
AO_GPIO_O, and the AO_GPIO_O_EN_N support only controlling output enable.

These bits of controlling pull enable are remapped to the new register
AO_RTI_PULL_UP_EN_REG, and the AO_RTI_PULL_UP_REG support only controlling
pull type(up/down).

The new layout of ao gpio/pull registers is as follows:
- AO_GPIO_O_EN_N        [offset: 0x9 << 2]
- AO_GPIO_I             [offset: 0xa << 2]
- AO_RTI_PULL_UP_REG    [offset: 0xb << 2]
- AO_RTI_PULL_UP_EN_REG [offset: 0xc << 2]
- AO_GPIO_O             [offset: 0xd << 2]

From above, we can see ao GPIO registers region has been separated by the
ao pull registers. In order to ensure the continuity of the region on
software, the ao GPIO and ao pull registers use the same base address, but
can be identified by the offset.

6daae00243 pinctrl: meson: meson8b: add the eth_rxd2 and eth_rxd3 pins
Gigabit Ethernet requires the Ethernet TXD0..3 and RXD0..3 data lines.
Add the missing eth_rxd2 and eth_rxd3 definitions so we don't have to
rely on the bootloader to set them up correctly.

The vendor u-boot sources for Odroid-C1 use the following Ethernet
pinmux configuration:
  SET_CBUS_REG_MASK(PERIPHS_PIN_MUX_6, 0x3f4f);
  SET_CBUS_REG_MASK(PERIPHS_PIN_MUX_7, 0xf00000);
This translates to the following pin groups in the mainline kernel:
- register 6 bit  0: eth_rxd1 (DIF_0_P)
- register 6 bit  1: eth_rxd0 (DIF_0_N)
- register 6 bit  2: eth_rx_dv (DIF_1_P)
- register 6 bit  3: eth_rx_clk (DIF_1_N)
- register 6 bit  6: eth_tx_en (DIF_3_P)
- register 6 bit  8: eth_ref_clk (DIF_3_N)
- register 6 bit  9: eth_mdc (DIF_4_P)
- register 6 bit 10: eth_mdio_en (DIF_4_N)
- register 6 bit 11: eth_tx_clk (GPIOH_9)
- register 6 bit 12: eth_txd2 (GPIOH_8)
- register 6 bit 13: eth_txd3 (GPIOH_7)
- register 7 bit 20: eth_txd0_0 (GPIOH_6)
- register 7 bit 21: eth_txd1_0 (GPIOH_5)
- register 7 bit 22: eth_rxd3 (DIF_2_P)
- register 7 bit 23: eth_rxd2 (DIF_2_N)

All functions except eth_rxd2 and eth_rxd3 are already supported by the
pinctrl-meson8b driver.

614b1868a1 pinctrl: meson: fix pull enable register calculation
We just changed the code so we apply bias disable on the correct
register but forgot to align the register calculation. The result
is that we apply the change on the correct register, but possibly
at the incorrect offset/bit

This went undetected because offsets tends to be the same between
REG_PULL and REG_PULLEN for a given pin the EE controller. This
is not true for the AO controller.

29ae0952e8 pinctrl: meson-g12a: add pinctrl driver support
Add the pinctrl driver for Meson-G12A SoC which share the similar IP as
the previous Meson-AXG SoC, both use same pinmux ops (register layout).
A new driver is needed here due to the differences in the pins.

Starting from Meson-AXG SoC, the pinctrl controller block use 4
continues register bits to specific the pin mux function, while comparing
to old generation SoC which using variable length register bits for
the pin mux definition. The new design greatly simplify the software model.

For the detail example, one 32bit register can be divided into 8 parts,
each has 4 bits whose value start from 0 - 7, each can describe one pin,
the value 0 is always devoted to GPIO function, while 1 - 7 devoted to
the mux pin function.

Please note, the GPIOE is actually located at AO (always on) bank.

55af415b42 pinctrl: meson: meson8b: fix requesting GPIOs greater than GPIOZ_3
Meson8b is a cost reduced variant of the Meson8 SoC. It's package size
is smaller than Meson8.
Unfortunately there are a few key differences which cannot be seen
without close inspection of the code and the public S805 datasheet:
- the GPIOX bank is missing the GPIOX_12, GPIOX_13, GPIOX_14 and
  GPIOX_15 GPIOs
- the GPIOY bank is missing the GPIOY_2, GPIOY_4, GPIOY_5, GPIOY_15 and
  GPIOY_16 GPIOs
- the GPIODV bank is missing all GPIOs except GPIODV_9, GPIODV_24,
  GPIODV_25, GPIODV_26, GPIODV_27, GPIODV_28 and GPIODV_29
- the GPIOZ bank is missing completely
- there is a new GPIO bank called "DIF"

This means that Meson8b only has 83 actual GPIO lines. Without any holes
there would be 130 GPIO lines in total (120 are inherited from Meson8
plus 10 new from the DIF bank).

GPIOs greater GPIOZ_3 (whose ID is 83 - as a reminder: this is exactly
the number of actual GPIO lines on Meson8b and also the value of
meson8b_cbus_pinctrl_data.num_pins) cannot berequested. Using CARD_6
(which used ID 100 prior to this patch, "base of the GPIO controller was
382) as an example:
$ echo 482 > /sys/class/gpio/export
export_store: invalid GPIO 482

This removes all non-existing pins from to dt-bindings header file
(include/dt-bindings/gpio/meson8b-gpio.h). This allows us to have a
consecutive numbering for the GPIO #defines (GPIOY_2 doesn't exist for
example, so previously the GPIOY_3 ID was "GPIOY_1 + 2", after this
patch it is "GPIOY_1 + 1"). As a nice side-effect this means that we get
compile-time (instead of runtime) errors if Meson8b .dts uses a pin that
only exists on Meson8.

Additionally the pinctrl-meson8b driver has to be updated to handle this
new GPIO numbering. By default a struct meson_bank only handles GPIO
banks where the pins are numbered consecutively because it calculates
the bit offsets based on the GPIO IDs.
This is solved by  taking the original BANK() definition and splitting it
into consecutive subsets (X0..11 and X16..21). The bit offsets for each
new bank includes the skipped GPIOs (the definition of the "X0..11" bank
is identical to the old "X" bank apart from the "last IRQ" field, the
definition of the new, split "X16..21" bank takes the original "X" bank
and adds 16 - the start of the new split bank - to the "first IRQ",
pullen bit, pull bit, dir bit, out bit and in bit).

Commit 984cffdeae ("pinctrl: Fix gpio/pin mapping for Meson8b")
fixed the same issue by setting "ngpio" (of the gpio_chip) to 130.
Unfortunately this broke in db80f0e158 ("pinctrl: meson: get rid of
unneeded domain structures").
The solution from this patch was considered to be better than the
previous attempt at fixing this because it provides compile-time error
checking for the GPIOs that exist on Meson8 but don't exist on Meson8b.

The following pins were tested on an Odroid-C1 using the sysfs GPIO
interface checking that their value (high or low) could be read:
- GPIOX_0, GPIOX_1, GPIOX_2, GPIOX_3, GPIOX_4, GPIOX_5, GPIOX_6,
  GPIOX_7, GPIOX_8, GPIOX_9, GPIOX_10, GPIOX_11, GPIOX_18, GPIOX_19,
  GPIOX_20, GPIOX_21
- GPIOY_3, GPIOY_7, GPIOY_8
(some of these had to be pulled up because they were low by default,
others were high by default so these had to be pulled down)

0fabe43f3f pinctrl: meson-axg: Introduce a pinctrl pinmux ops for Meson-AXG SoC
The pin controller has been updated in the Amlogic Meson AXG series,
which use continuous 4-bit register to select function for each pin.
In order to support this, a new pinmux operations "meson_axg_pmx_ops"
has been added.

ce385aa24a pinctrl: meson: rework pinmux ops
This change prepare the introduction of new meson SoC. This new SoC will
share the same gpio/pinconf registers but the pinmux part will be
different. While the format of the data associated with each pinmux group
will change, the way to handle pinmuxing will be similar.

To deal with this new situation, the meson_pmx_struture is kept but the
data associated to it is now generic. This allows to reuse the basic
functions which would otherwise be copy/pasted in each pinmux driver
(such as getting the name a count of groups and functions) Only the
functions actually using this specific data is taken out of the common
code and is handling the SoC pinmuxing

277d14eb81 pinctrl: meson: separate soc drivers
When meson pinctrl is enabled, all meson platforms pinctrl drivers are
built in the kernel, with a significant amount of data.

This leads to situation where pinctrl drivers targeting an architecture
are also compiled and shipped on another one (ex: meson8 - ARM - compiled
and shipped on ARM64 builds). This is a waste of memory we can easily
avoid.

This change makes 4 pinctrl drivers (1 per SoC) out the original single
driver, allowing to compile and ship only the ones required.
