pinctrl: palmas: add pincontrol driver

2013-08-14T19:00:42+00:00

TI Palmas series Power Management IC have multiple pins which can be
configured for different functionality. This pins can be configured
for different function. Also their properties like pull up/down,
open drain enable/disable are configurable.

Add support for pincontrol driver Palmas series device like TPS65913,
TPS80036. The driver supports to be register from DT only.

Changes from V1:
- Add generic property for pins and functions in pinconf-generic.
- Add APIs to map the DT and subnode.
- Move common utils APIs to the pinctrl-utils from this file.
- Update the binding document accordingly.
Changes from V2:
- Add ack by Lee.
- Correct the binding docs.

pinctrl: add utility functions for add map/configs

2013-08-14T19:00:41+00:00

Some of pincontrol driver needs the utility function to create map
list. The utility function needed for adding mux, configs etc.

In place of duplicating this in each driver, add the common utility
function in common file and use from device specific driver. This will
reduce the duplicating of code across drivers.

Changes from V1:
- Add this files in this patch and add common utility APIs to here.

Changes from V2:
- Nothing in code.
- Added Reviewed by Stephen.

Pull pin control changes from Linus Walleij:

- A large slew of improvements of the Genric pin configuration support,
and deployment in four different platforms: Rockchip, Super-H PFC,
ABx500 and TZ1090. Support BIAS_BUS_HOLD, get device tree parsing
and debugfs support into shape.

- We also have device tree support with generic naming conventions for
the generic pin configuration.

- Delete the unused and confusing direct pinconf API. Now state
transitions is *the* way to control pins and multiplexing.

- New drivers for Rockchip, TZ1090, and TZ1090 PDC.

- Two pin control states related to power management are now handled in
the device core: "sleep" and "idle", removing a lot of boilerplate
code in drivers. We do not yet know if this is the final word for
pin PM, but it already make things a lot easier to handle.

- Handle sparse GPIO ranges passing a list of disparate pins, and
utilize these in the new BayTrail (x86 Atom SoC) driver.

- Make the sunxi (AllWinner) driver handle external interrupts.

- Make it possible for pinctrl-single to handle the case where several
pins are managed by a single register, and augment it to handle sleep
modes.

- Cleanups and improvements for the abx500 drivers.

- Move Sirf pin control drivers to their own directory, support
save/restore of context and add support for the SiRFatlas6 SoC.

- PMU muxing for the Dove pinctrl driver.

- Finalization and support for VF610 in the i.MX6 pinctrl driver.

- Smoothen out various Exynos rough edges.

- Generic cleanups of various kinds.

Pull regmap updates from Mark Brown:
 "A small but useful set of regmap updates this time around:

   - An abstraction for bitfields within a register map contributed by
     Srinivas Kandagatla, allowing drivers to cope more easily when
     hardware designers randomly move things about (mainly when talking
     to things like system controllers).

   - Changes from Lars-Peter Clausen to allow the MMIO regmap to be used
     from hard IRQ context.

   - Small improvements to the cache infrastructure and performance,
     including a default cache sync operation so now all regmaps can
     sync easily.

  There's also a pinctrl driver making use of the new bitfield API,
  merged here for dependency reasons.  There will be a simple add/add
  conflict with the pinctrl tree as a result."

This patch add pinctrl support to ST SoCs.

About hardware:
ST Set-Top-Box parts have two blocks called PIO and PIO-mux which handle
pin configurations.

Each multi-function pin is controlled, driven and routed through the PIO
multiplexing block. Each pin supports GPIO functionality (ALT0) and
multiple alternate functions(ALT1 - ALTx) that directly connect the pin
to different hardware blocks. When a pin is in GPIO mode, Output Enable
(OE), Open Drain(OD), and Pull Up (PU) are driven by the related PIO
block. Otherwise the PIO multiplexing block configures these parameters
and retiming the signal.

About driver:
This pinctrl driver manages both PIO and PIO-mux block using pinctrl,
pinconf, pinmux, gpio subsystems. All the pinctrl related config
information can only come from device trees.

pinctrl-tz1090-pdc: add TZ1090 PDC pinctrl driver

2013-06-24T15:21:38+00:00

Add a pin control driver for the TZ1090's low power pins via the
powerdown controller SOC_GPIO_CONTROL registers.

These pins have individually controlled pull-up, and group controlled
schmitt, slew-rate, drive-strength, and power-on-start (pos).

The pdc_gpio0 and pdc_gpio1 pins can also be muxed onto the
ir_mod_stable_out and ir_mod_power_out functions respectively. If no
function is set they remain in GPIO mode. These muxes can be overridden
by requesting them as GPIOs.

pinctrl: add Intel BayTrail GPIO/pinctrl support

2013-06-18T15:23:40+00:00

Add support for gpio on Intel BayTrail platforms. BayTrail supports 3 banks
of gpios called SCORE, NCORE ans SUS with 102, 28 and 44 gpio pins.
Supports gpio interrupts and ACPI gpio events

Pins may be muxed to alternate function instead of gpio by firmware.
This driver does not touch the pin muxing and expect firmare
to set pin muxing and pullup/down properties properly.

pinctrl: add pinctrl driver for Rockchip SoCs

2013-06-16T09:57:32+00:00

This driver adds support the Cortex-A9 based SoCs from Rockchip,
so at least the RK2928, RK3066 (a and b) and RK3188.
Earlier Rockchip SoCs seem to use similar mechanics for gpio
handling so should be supportable with relative small changes.
Pull handling on the rk3188 is currently a stub, due to it being
a bit different to the earlier SoCs.

Pinmuxing as well as gpio (and interrupt-) handling tested on
a rk3066a based machine.
