[PATCH RESEND v3 0/9] Add STM32 pinctrl/GPIO driver

From: Maxime Coquelin
Date: Fri Dec 11 2015 - 03:25:21 EST


Hi Linus, Patrice,

I resend the series for Patrice to review it.

Thanks,
Maxime



This is the third round of STM32 pinctrl series, which improves DT
bindings declaration and documentation, and also fixes some commit fixup
issues. The series also contains two more patches, adding GPIO LEDs
support as a user of this driver.

The STM32 family has 16 pins per GPIO bank, and the number of bank varies
depending on the model.

Pins can be multiplexed either in GPIO mode, alternate function (up to 15
functions per pin) or analog (for ADC/DAC).

Changes since v2:
-----------------
- Rebase on v4.4-rc1
- Declare leds also for Eval board
- Set green led as heartbeat
- Collect some acks

Changes since v1:
-----------------
- Add GPIO LEDs support in DT and defconfig
- Changes pinmux DT bindings from macros to raw values (Daniel)
- Improve DT bindings documentation (Daniel)
- Fix some commit fixup and rebase issues.

Kind regards,
Maxime
