Subject: pinctrl: sh-pfc: r8a7790: Implement voltage switching for SDHI

All the SHDIs can operate with either 3.3V or 1.8V signals, depending
on negotiation with the card.

Implement the {get,set}_io_voltage operations and set the related
capability flag for the associated pins.

Subject: pinctrl: sh-pfc: IPSRx and MOD_SELx should be set before GPSRx

Gen2 / Gen3 datasheet will have below note in next version.
This patch follows this note.

IPSRx and MOD_SELx registers shall be set before setting GPSRx
registers in case that they need to be configured.
MOD_SELx registers can be set either earlier or later than setting
IPSRx registers.

Subject: pinctrl: sh-pfc: r8a7795: Add drive strength support

Define the drive strength registers for the R8A7795. As the PFC driver
for the SoC only defines GPIO pins at the moment, limit drive strength
support to those pins. Pins without GPIO capabilities will be supported
later.

Subject: pinctrl: amd:Add device HID for future AMD GPIO controller

Add device HID AMDI0030 to match the AMD ACPI Vendor ID (AMDI) as
registered in http://www.uefi.org/acpi_id_list, and the GPIO controller
on future AMD paltform will use the HID instead of AMD0030.

Subject: pinctrl: Rename pinctrl_utils_dt_free_map to pinctrl_utils_free_map

Rename pinctrl_utils_dt_free_map to pinctrl_utils_free_map, since
it does not depend on device tree despite the current name. This
will enforce a consistent naming in pinctr-utils.c and will make
it clear it can be called from outside device tree (e.g. from
ACPI handling code).

Subject: pinctrl: baytrail: Add pin control data structures

In order to implement pin control for Baytrail, we need data
structures in which to store and pass along pin, group, function,
community and SOC data information.

Baytrail has 3 GPIO controllers. Add SCORE, NCORE and SUS
controller data:
- pins (for all controllers),
- pad map for pins (for all controllers; we need this since pads
  are not ordered),
- groups (for SCORE and SUS controllers),
- functions (for SCORE and SUS controllers),
- communities (for all controllers),
- soc specific data gathering all of the above and the ACPI UID
  (for all controllers)

This information is useful for pin control functionality.
NCORE data is lighter than the other two controllers' due to
lack of pin documentation in the public datasheet.

Datasheet:

From c501d0b149de1248fa9c29c906bf70f3b87b8bd8 Mon Sep 17 00:00:00 2001
From: Cristina Ciocan <cristina.ciocan@intel.com>
Date: Fri, 1 Apr 2016 14:00:03 +0300
Subject: pinctrl: baytrail: Add pin control operations

Add implementation for:
- pin control, group information retrieval: count, name and pins
- pin muxing:
  - function information (count, name and groups)
  - mux setting
  - gpio control (enable, disable, set direction)
- pin configuration:
  - pull disable
  - pull up/down and pull strength
  - debounce
  - any other option is treated as not supported.

Subject: pinctrl: baytrail: Update gpio chip operations

This patch updates the gpio chip implementation in order
to interact with the pin control model: the chip contains
reference to SOC data and pin/group/community information
is retrieved through the SOC reference.

Subject: pinctrl: baytrail: Update irq chip operations

This patch updates the irq chip implementation in order
to interact with the pin control chip model: the chip
contains reference to SOC data and pin/group/community
information is retrieved through the SOC reference.

Subject: pinctrl: baytrail: Register pin control handling

This patch updates device's probing, removal and irq handling in order to
register it as pinctrl device. Pin control data is matched by ACPI UID,
since it is passed along as driver data in acpi_device_id structure.

Subject: pinctrl: rockchip: add support the get_direction

This patch adds the get_direction to support the gpio
interface.

The gpio direction is not used on rockchip platform when use the gpio
debugfs.

Tested on kylin board. (RK3036 SoCs)
The repro steps:
$/sys/class/gpio/
echo 53 > export
$/sys/class/gpio/gpio53# cat direction
in
In general, the gpio53 should be out value, but the direction is the
default value 'in',  since the get_direction didn't supported in rockchip
pinctrl.

So, we should add this patch to support it.

Subject: pinctrl: tegra: clear park bit for all pins

Parking bits might not be cleared by the bootloader properly (if for
instance it doesn't use the device configured by that pin). Clear
the park bits for all the pins during pinctrl probe.

This is present on T210 platforms but not earlier ones, so for earlier
generations, set parked_reg = -1 to disable.

The park bit is used to prevent glitching when reprogramming pinctrl
registers.

Based on work by:

Subject: pinctrl: pxa: add pxa25x architecture

Add the pxa25x architecture, which is a pxa2xx with 85 pins. The
registers spacing, and pins logic is common to pxa2xx, only the pins and
their alternate function are specific to pxa25x.

Subject: pinctrl: sh-pfc: r8a7794: Add DU pin groups

r8a7794 PFC DU support from the R-Car Gen2 v1.9.4 BSP

[Magnus: added the description, added missing dot clock output signals,
separated CDE and DISP signals, broke out the ODDF signal from the sync
group.]

[Sergei: resolved rejects, folded in Magnus' patches, killed empty lines,
reordered pin/mux arrays and pin groups, fixed up some comments to the pin
arrays, removed the "du" function splitting its groups between the "du0"
and "du1" functions.]

Subject: pinctrl: Add devm_ apis for pinctrl_{register, unregister}

Add device managed APIs devm_pinctrl_register() and
devm_pinctrl_unregister() for the APIs pinctrl_register()
and pinctrl_unregister().

This helps in reducing code in error path and sometimes
removal of .remove callback for driver unbind.

Subject: pinctrl: exynos5440: Use off-stack memory for pinctrl_gpio_range

The range is registered into a linked list which can be referenced
throughout the lifetime of the driver. Ensure the range's memory is useful
for the same lifetime by adding it to the driver's private data structure.

The bug was introduced in the driver's initial commit, which was present in
v3.10.

Subject: pinctrl: nomadik: use BIT() with offsets consequently

This driver is confusing in referencing/dereferencing the global
GPIO number scope in some places and using local offsets in other
places. Remove some of the confusion by removing local "bit" and
"bitmask" definitions and just use BIT(offset) directly. Also
unexport a function only used in this file.

but a new user appeared in the other patch:

Subject: pinctrl: nomadik: hide nmk_gpio_get_mode when unused

nmk_gpio_get_mode is only used in one place, and that is conditionally
compiled if DEBUG_FS is enabled. A recent cleanup has marked the
definition 'static', which now leads to a warning:

drivers/pinctrl/nomadik/pinctrl-nomadik.c:614:12: error: 'nmk_gpio_get_mode' defined but not used [-Werror=unused-function]
 static int nmk_gpio_get_mode(struct nmk_gpio_chip *nmk_chip, int offset)
            ^~~~~~~~~~~~~~~~~

Moving the function itself inside the #ifdef shuts it up again.

Subject: pinctrl: rockchip: fix pull setting error for rk3399

This patch fixes the pinctrl pull bias setting, since the pull up/down
setting is the contrary for gpio0(just the gpio0a and gpio0b) and
gpio2(just the gpio2c and gpio2d).

From the TRM said, the gpio0a pull polarity setting:
gpio0a_p
GPIO0A PE/PS programmation section, every
GPIO bit corresponding to 2bits[PS:PE]
2'b00: Z(Normal operation);
2'b11: weak 1(pull-up);
2'b01: weak 0(pull-down);
2'b10: Z(Normal operation);

Then, the other gpios setting as the following:
gpio1a_p (e.g.: gpio1, gpio2a, gpio2b, gpio3...)
GPIO1A PU/PD programmation section, every
GPIO bit corresponding to 2bits
2'b00: Z(Normal operation);
2'b01: weak 1(pull-up);
2'b10: weak 0(pull-down);
2'b11: Z(Normal operation);

For example,(rk3399evb board)
sdmmc_cd --->gpio0_a7
localhost / # io -r -4 0xff320040
ff320040: 00004d5f
In general,the value should be 0x0000cd5f since the pin has been set
in the dts.

Subject: pinctrl: tegra: Correctly check the supported configuration

The pincontrol registers of Tegra chips has multiple filed per
registers. There is two type of registers mux and drive. All
configurations belongs to one of these registers.

If any configurations are supported then <config>_bit is set to
bit position of these registers otherwise -1 to not support it.
The member is defined as
	s32 <config>_bit:6;

So if config is not supported ifor given SoC then it is set to -1
in soc pinmmux table.
In common driver code, to find out that given config is supported
or not, it is checked as:

s8 bit = <config>_bit;
if (bit > 31) {
	/* Not supported config */
}

But in this case, bit is s8 and hence for non supporting it is -1.

Correct the check as:
if (bit < 0) {
	/* Not supported config */
}

Subject: pinctrl: tegra: avoid parked_reg and parked_bank

NVIDIA's Tegra210 support the park bit to make pinmux configuration
enable/disable. If parked bit is 1 then configuration does not apply
and if it is 0 then pinmux configuration applies. This is to support
to avoid any glitch in pinmux configurations.

The parked bit is part of mux register and mux bank and hence it is
not required to have member for the parked_reg and parked bank very
similar to other bit field of the same register.

Remove the need of the parked register and parked bank and get whether
parked function supported or not by parked_bit.

This is to make the parked bit handling same as other fields of mux
registers.
