Linus Torvalds ff61bc81b3 Pin control bulk changes for the v5.18 kernel cycle
No core changes this time. Just new driver code and improvements!
 
 New drivers:
 
 - New driver for the Broadcom BCM4908 SoC.
 
 - New subdriver for Tesla FSD (Full Self Driving) SoC, a
   derivative of the Samsung Exynos pin control driver.
 
 - New driver for the Amlogic Meson S4 SoC.
 
 - New driver for the Sunplus SP7021 SoC.
 
 - New driver for the Microsemi Ocelot family ServalT SoC.
 
 - New subdriver for Intel Alder Lake-M SoC.
 
 - New subdriver for Intel Ice Lake-N SoC, including PCH support.

Aidan MacDonald 9279c00fa4 pinctrl: ingenic: Fix regmap on X series SoCs
The X series Ingenic SoCs have a shadow GPIO group which is at a higher
offset than the other groups, and is used for all GPIO configuration.
The regmap did not take this offset into account and set max_register
too low, so the regmap API blocked writes to the shadow group, which
made the pinctrl driver unable to configure any pins.

Fix this by adding regmap access tables to the chip info. The way that
max_register was computed was also off by one, since max_register is an
inclusive bound, not an exclusive bound; this has been fixed.

Linus Torvalds ed4643521e ARM: DT updates for 5.18
After a somewhat quiet 5.17 release, the size of the DT changes
 is a bit larger again. There are nine new SoC that get added,
 all of them related to existing platforms:
 
  - Airoha (formerly Mediatek/EcoNet) EN7523 networking SoC and EVB
 
  - Mediatek mt6582 tablet platform with the Prestigio PMT5008 3G tablet
 
  - Microchip Lan966 networking SoC and it evaluation board
 
  - Qualcomm Snapdragon 625/632 midrange phone SoCs, with the
    LG Nexus 5X and Fairphone FP3 phones
 
  - Renesas RZ/G2LC and RZ/V2L general-purpose embedded SoCs,
    along with their evaluation boards
 
  - Samsung Exynos 850 phone SoC and reference board
 
  - Samsung Exynos7885 with the Samsung Galaxy A8 (2018) phone
 
  - Tesla FSD (Fully Self-Driving), an automotive SoC losely derived
    from the Samsung Exynos family.
 
  - TI K3/AM62 SoC and reference board
 
 Support for additional functionality in existing dts files is added all
 over the place: Samsung, Renesas, Mstar, wpcm450, OMAP, AT91, Allwinner,
 i.MX, Tegra, Aspeed, Oxnas, Qualcomm, Mediatek, and Broadcom.
 
 Samsung has a rework for its pinctrl schema that is a bit tricky and
 requires driver changes to be included here.
 
 A few more platforms only have smaller cleanups and DT Schema fixes,
 this includes SoCFPGA, ux500, ixp4xx, STi, Xilinx Zynq, LG, and Juno.
 
 The new machines are really too many to list, but I'll do it anyway:
 
  Allwinner:
    - A20-Marsboard development board
 
  Amlogic
   - Amediatek X96-AIR (Amlogic S905X3)
   - CYX A95XF3-AIR (Amlogic S905X3)
   - Haochuangy H96-Max (Amlogic S905X3)

AngeloGioacchino Del Regno 156f721704 pinctrl: mediatek: common-v1: Commonize spec_ies_smt_set callback
All of the MediaTek pinctrl drivers registering with pinctrl-mtk-common
that are offering a .spec_ies_smt_set() callback are declaring their
own function which is doing exactly the same on all drivers: calling
mtk_pconf_spec_set_ies_smt_range() with their struct and a simple check.

Commonize this callback by adding the ies and smt structure pointers
to struct mtk_pinctrl_devdata and changing the callback signature to
take it.

Removing the callback and checking for the existance of the spec_smt
and/or spec_ies data would allow us to staticize the function
mtk_pconf_spec_set_ies_smt_range(), but this solution was avoided as
to keep flexibility, as some SoCs may need to perform a very different
operation compared to what this commonized function is doing.

AngeloGioacchino Del Regno c8c206cdc1 pinctrl: mediatek: common-v1: Use common probe function
Most of the mediatek pinctrl drivers are calling mtk_pctrl_init() and
passing only a pointer to struct mtk_pinctrl_devdata, as the regmap
handle it passed from device-tree, with the exception of mt6397.

For all of the drivers that don't require passing a struct regmap
pointer from a parent device, simplify the probe mechanism by assigning
the required structure as match data and use mtk_pctrl_common_probe()
as their probe function.

While at it, also collapse the of_device_id entries to a single line,
as they all fit in max 83 columns, which is acceptable.

Michael Walle 1f3c85c22d pinctrl: microchip-sgpio: wait until output is actually set
Right now, when a gpio value is set, the actual hardware pin gets set
asynchronously. When linux write the output register, it takes some time
until it is actually propagated to the output shift registers. If that
output port is connected to an I2C mux for example, the linux driver
assumes the I2C bus is already switched although it is not.

Fortunately, there is a single shot mode with a feedback: you can
trigger the single shot and the hardware will clear that bit once it has
finished the clocking and strobed the load signal of the shift
registers. This can take a considerable amount of time though.
Measuremens have shown that it takes up to a whole burst cycle gap which
is about 50ms on the largest setting. Therefore, we have to mark the
output bank as sleepable. To avoid unnecessary waiting, just trigger the
single shot if the value was actually changed.

Chen-Yu Tsai e5fabbe43f pinctrl: mediatek: paris: Support generic PIN_CONFIG_DRIVE_STRENGTH_UA
Some of the MediaTek chips that utilize the Paris pinctrl driver library
support a lower drive strength (<= 1mA) than the standard drive strength
settings (2~16 mA) on certain pins. This was previously supported by the
custom MTK_PIN_CONFIG_DRV_ADV parameter along with the
"mediatek,drive-strength-adv" device tree property.

The drive strength values for this hardware are 125, 250, 500, and 1000 mA,
and can be readily described by the existing "drive-strength-microamp"
property, which then gets parsed by the generic pinconf library into the
parameter PIN_CONFIG_DRIVE_STRENGTH_UA.

Add support for PIN_CONFIG_DRIVE_STRENGTH_UA while keeping the old
custom parameter around for backward compatibility.

function pointers and returning -ENOTSUPP if it is not valid. This is
done for multiple pin config settings and results in the code that
handles the supporting cases to get indented by one level. This is
aggrevated by the fact that some features require another level of
conditionals.

Instead of assigning the same error code in all unsupported optional
feature cases, simply have that error code as the default, and break
out of the switch/case block whenever a feature is unsupported, or an
error is returned. This reduces indentation by one level for the useful
code.

Also replace the goto statements with break statements. The result is
the same, as the gotos simply exit the switch/case block, which can
also be achieved with a break statement. With the latter the intent
is clear and easier to understand.

Chen-Yu Tsai fcde2a3fc8 pinctrl: mediatek: paris: Drop extra newline in mtk_pctrl_show_one_pin()
The caller of mtk_pctrl_show_one_pin() is responsible for printing the
full line. mtk_pctrl_show_one_pin(), called through mtk_pctrl_dbg_show(),
should only produce a string containing the extra information the driver
wants included.

Drop the extra newlines. Also unbreak the line that is only slightly
over 80 characters to make it easier on the eye, and get rid of the
braces now that each block in the conditionals is just one line.

Chen-Yu Tsai 54fe55fb38 pinctrl: mediatek: paris: Fix pingroup pin config state readback
mtk_pconf_group_get(), used to read back pingroup pin config state,
simply returns a set of configs saved from a previous invocation of
mtk_pconf_group_set(). This is an unfiltered, unvalidated set passed
in from the pinconf core, which does not match the current hardware
state.

Since the driver library is designed to have one pin per group, pass
through mtk_pconf_group_get() to mtk_pinconf_get(), to read back the
current pin config state of the only pin in the group.

Also drop the assignment of pin config state to the group.

Jonathan Neuschäfer a1d1e0e3d8 pinctrl: nuvoton: Add driver for WPCM450
This driver is based on the one for NPCM7xx, because the WPCM450 is a
predecessor of those SoCs. Notable differences:

- On WPCM450, the GPIO registers are not organized in multiple banks,
  but rather placed continually into the same register block. This
  affects how register offsets are computed.
- Pinmux nodes can explicitly select GPIO mode, whereas in the npcm7xx
  driver, this happens automatically when a GPIO is requested.

Some functionality implemented in the hardware was (for now) left unused
in the driver, specifically blinking and pull-up/down.
