56b367c0cd pinctrl: single: Fix pcs_parse_bits_in_pinctrl_entry to use __ffs than ffs
pcs_parse_bits_in_pinctrl_entry uses ffs which gives bit indices
ranging from 1 to MAX. This leads to a corner case where we try to request
the pin number = MAX and fails.

bit_pos value is being calculted using ffs. pin_num_from_lsb uses
bit_pos value. pins array is populated with:

pin + pin_num_from_lsb.

The above is 1 more than usual bit indices as bit_pos uses ffs to compute
first set bit. Hence the last of the pins array is populated with the MAX
value and not MAX - 1 which causes error when we call pin_request.

mask_pos is rightly calculated as ((pcs->fmask) << (bit_pos - 1))
Consequently val_pos and submask are correct.

Hence use __ffs which gives (ffs(x) - 1) as the first bit set.

5fedbb9239 pinctrl: mediatek: correct debounce time unit in mtk_gpio_set_debounce
The debounce time unit for gpio_chip.set_debounce is us but
mtk_gpio_set_debounce regard it as ms.
Fix this by correct debounce time array dbnc_arr so it can find correct
debounce setting. Debounce time for first debounce setting is 500us,
correct this as well.

While I'm at it, also change the debounce time array name to
"debounce_time" for readability.

26e6aaafc8 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.

6ba20a00a3 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.

c501d0b149 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.

c8f5c4c7c8 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:

d32f7fd3bb 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).
