8a74a53ebb pinctrl: meson: Constify some structures
The following structures are not modified in these drivers.
  - struct meson_bank
  - struct meson_pmx_bank
  - struct meson_pmx_func
  - struct meson_pmx_group
  - struct meson_pinctrl_data
  - struct meson_axg_pmx_data

Constifying these structures moves some data to a read-only section, so
increase overall security.

On a x86_64, with allmodconfig:

060f03e954 pinctrl: Explicitly include correct DT includes
The DT of_device.h and of_platform.h date back to the separate
of_platform_bus_type before it as merged into the regular platform bus.
As part of that merge prepping Arm DT support 13 years ago, they
"temporarily" include each other. They also include platform_device.h
and of.h. As a result, there's a pretty much random mix of those include
files used throughout the tree. In order to detangle these headers and
replace the implicit includes with struct declarations, users need to
explicitly include the correct includes.

f088ab6d4f pinctrl: meson: fix drive strength register and bit calculation
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.

5ab0c8e901 pinctrl: meson: meson8b: add the GPIOH pinmux settings for ETH_RXD{2,3}
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).

These settings were found in the public "Amlogic Ethernet controller

35c60be220 pinctrl: meson: Fix wrong shift value when get drive-strength
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.

dabad1ff85 pinctrl: meson: add pinctrl driver support for Meson-A1 SoC
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.

fd42296407 pinctrl: meson: add a new callback for SoCs fixup
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:

|      |  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.

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.

Merge tag 'pinctrl-v5.3-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl

Pull pin control updates from Linus Walleij:
 "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"

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.
