pinctrl: tegra: Separate Tegra194 instances

2022-11-14T13:16:46+00:00

Tegra194 has two separate instances of the pin controller, one called
AON (in the always-on domain) and another called "main". Instead of
treating them as a single pin controller, split them up into two
separate controllers. Doing so allows the mapping between the pinmux
and GPIO controllers to be trivial identity mappings and more cleanly
separates the AON from the main IP blocks.

pinctrl: tegra: Add missing header(s)

2022-10-24T14:06:47+00:00

Do not imply that some of the generic headers may be always included.
Instead, include explicitly what we are direct user of.

While at it, sort headers alphabetically.

pinctrl: tegra: tegra194: drop unused pin groups

2022-05-04T21:40:05+00:00

The sdmmc1_hv_trim_pins, sdmmc3_hv_trim_pins and sys_reset_n_pins are
not defined as pin groups:

  drivers/pinctrl/tegra/pinctrl-tegra194.c:1119:27: error: ‘sdmmc3_hv_trim_pins’ defined but not used [-Werror=unused-const-variable=]
   1119 | static const unsigned int sdmmc3_hv_trim_pins[] = {

Proper fix would be to define them, but this requires knowledge from
datasheet.  Removal should not cause any harm and at least it silences
the warnings.

pinctrl: tegra194: remove duplicate initializer again

An earlier bugfix removed a duplicate field initializer in

pinctrl: tegra: Return const pointer from tegra_pinctrl_get_group()

2021-11-16T01:19:14+00:00

Instead of returning const pointer from tegra_pinctrl_get_group()
the return value is being casted.

pinctrl: tegra: Use correct offset for pin group

2021-10-25T23:27:39+00:00

Function tegra_pinctrl_gpio_request_enable() and
tegra_pinctrl_gpio_disable_free() uses pin offset instead
of group offset, causing the driver to use wrong offset
to enable gpio.

Add a helper function tegra_pinctrl_get_group() to parse the
pin group and determine correct offset.

Merge tag 'pinctrl-v5.9-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl

2020-08-09T19:52:28+00:00

Pull pin control updates from Linus Walleij:
"This is the bulk of the pin control changes for the v5.9 kernel
series:

Core changes:

- The GPIO patch "gpiolib: Introduce for_each_requested_gpio_in_range()
macro" was put in an immutable branch and merged into the pinctrl
tree as well. We see these changes also here.

- Improved debug output for pins used as GPIO.

New drivers:

- Ocelot Sparx5 SoC driver.

- Intel Emmitsburg SoC subdriver.

- Intel Tiger Lake-H SoC subdriver.

- Qualcomm PM660 SoC subdriver.

- Renesas SH-PFC R8A774E1 subdriver.

Driver improvements:

- Linear improvement and cleanups of the Intel drivers for
Cherryview, Lynxpoint, Baytrail etc. Improved locking among other
things.

- Renesas SH-PFC has added support for RPC pins, groups, and
functions to r8a77970 and r8a77980.

- The newere Freescale (now NXP) i.MX8 pin controllers have been
modularized. This is driven by the Google Android GKI initiative I
think.

- Open drain support for pins on the Qualcomm IPQ4019.

- The Ingenic driver can handle both edges IRQ detection.

- A big slew of documentation fixes all over the place.

- A few irqchip template conversions by yours truly.
