fe202ea8e5 pinctrl: rockchip: do coding style for mux route struct
The mux route tables take many lines for each SoC, and it will be more
instances for newly SoC, that makes the file size increase larger.

This patch only do coding style for mux route struct, by adding a new
definition and replace the structs by script which supplied by
huangtao@rock-chips.com

09e11caaa4 pinctrl: Add PIN_CONFIG_MODE_PWM to enum pin_config_param
It seems that we will have more and more pin controllers that support
PWM function on the (selected) pins. Due to it being a part of pin
controller IP the idea is to have some code that will switch the mode
and attach the corresponding driver, for example, via using it as
a library. Meanwhile, put a corresponding item to the pin_config_param
enumerator.

56ab29ec6f pinctrl: mediatek: use spin lock in mtk_rmw
Commit 42a46434e9b1 ("pinctrl: add lock in mtk_rmw function.") uses
mutex lock in mtk_rmw.  However the function is possible called from
atomic context.

For example call trace:
  mutex_lock+0x28/0x64
  mtk_rmw+0x38/0x80
  [snip]
  max98357a_daiops_trigger+0x8c/0x9c
  soc_pcm_trigger+0x5c/0x10c

The max98357a_daiops_trigger() could run in either atomic or non-atomic
context.  As a result, dmesg shows some similar messages: "BUG: sleeping
function called from invalid context at kernel/locking/mutex.c:254".

Uses spin lock in mtk_rmw instead.

5e6332a7ff pinctrl: Ingenic: Improve LCD pins related code.
1.In the JZ4740 part, remove pointless "lcd-no-pins", use "lcd-special"
  and "lcd-generic" instead "lcd-18bit-tft". Currently, in the mainline,
  no other devicetree out there is using the "lcd-18bit-tft" ABI, so we
  should be able to replace it safely.
2.In the JZ4725B part, adjust the location of the LCD pins related code
  to keep them consistent with the style of other parts.
3.In the JZ4760 part, add the missing comma and adjust element order in
  "jz4760_lcd_special_pins[]", keep them in the order of CLS/SPL/PS/REV
  like other "lcd_special_pins" arrays. And adjust the location of the
  "jz4760_lcd_generic" related code to keep them consistent with the
  style of other parts.
4.In the JZ4770 part, remove pointless "lcd-no-pins", add the missing
  "lcd-16bit", "lcd-18bit", "lcd-special", "lcd-generic".
5.In the X1000 part and the X1500 part, remove pointless "lcd-no-pins".
6.In the X1830 part, replace "lcd-rgb-18bit" with "lcd-tft-8bit" and
  "lcd-tft-24bit", because of the description of the TRANS_CONFIG.MODE
  register bits in the PM manual of the X1830, shows that the X1830 only
  supppots 24bit mode and 8bit mode for tft interface, only 18 pins in
  the GPIO table are because of the data[17:16], the data[9:8], and the
  data[1:0] has not been connected. And according to the description,
  the two interfaces supported by X1830 are respectively referred to as
  "TFT interface" and "SLCD interface", so the "lcd-rgb-xxx" is replaced
  with "lcd-tft-xxx" to avoid confusion.

cbde6c823b pinctrl: at91-pio4: Fix slew rate disablement
The slew rate was enabled by default for each configuration of the
pin. In case the pin had more than one configuration, even if
we set the slew rate as disabled in the device tree, the next pin
configuration would set again the slew rate enabled by default,
overwriting the slew rate disablement.
Instead of enabling the slew rate by default for each pin configuration,
enable the slew rate by default just once per pin, regardless of the
number of configurations. This way the slew rate disablement will also
work for cases where pins have multiple configurations.

fa0c10a5f3 pinctrl: samsung: use 'int' for register masks in Exynos
The Special Function Registers on all Exynos SoC, including ARM64, are
32-bit wide, so entire driver uses matching functions like readl() or
writel().  On 64-bit ARM using unsigned long for register masks:
1. makes little sense as immediately after bitwise operation it will be
   cast to 32-bit value when calling writel(),
2. is actually error-prone because it might promote other operands to
   64-bit.

The "invalid function %d on pin %d .\n" message is triplicated in the

now print the pin number and AF consistently, so it is easier to debug
