pinctrl: meson: meson8b: fix the sdxc_a data 1..3 pins

2019-02-17T21:24:32+00:00

Fix the mismatch between the "sdxc_d13_1_a" pin group definition from
meson8b_cbus_groups and the entry in sdxc_a_groups ("sdxc_d0_13_1_a").
This makes it possible to use "sdxc_d13_1_a" in device-tree files to
route the MMC data 1..3 pins to GPIOX_1..3.

Pull pin control updates from Linus Walleij:
 "We have no core changes but lots of incremental development in drivers
  all over the place: Renesas, NXP, Mediatek and Actions Semiconductor
  keep churning out new SoCs.

  I have some subtree maintainers for Renesas and Intel helping out to
  keep down the load, it's been working smoothly (Samsung also have a
  subtree but it was not used this cycle.)

  New drivers:

   - NXP (ex Freescale) i.MX 8 QXP SoC driver.

   - Mediatek MT6797 SoC driver.

   - Mediatek MT7629 SoC driver.

   - Actions Semiconductor S700 SoC driver.

   - Renesas RZ/A2 SoC driver.

   - Allwinner sunxi suniv F1C100 SoC driver.

   - Qualcomm PMS405 PMIC driver.

   - Microsemi Ocelot Jaguar2 SoC driver.

  Improvements:

   - Some RT improvements (using raw spinlocks where appropriate).

   - A lot of new pin sets on the Renesas PFC pin controllers.

   - GPIO hogs now work on the Qualcomm SPMI/SSBI pin controller GPIO
     chips, and Xway.

   - Major modernization of the Intel pin control drivers.

   - STM32 pin control driver will now synchronize usage of pins with
     another CPU using a hardware spinlock"

pinctrl: meson: meson8b: add the missing GPIO_GROUPs for BOOT and CARD

2018-12-21T10:00:54+00:00

Add the BOOT and CARD pins as GROUP_GROUPs as well so they can be
configured in devicetree using groups = BOOTx or groups = CARDx. This
makes the behavior consistent with other pins inside the same driver as
well as with the BOOT and CARD pins of the GXBB and GXL pinctrl drivers.

pinctrl: meson: meson8: rename the "gpio" function to "gpio_periphs"

2018-12-21T09:59:58+00:00

Rename the existing "gpio" function to "gpio_periphs". This makes it
consistent with the "gpio_aobus" function. Also GXBB and GXL are also
using the "gpio_periphs" naming, so this makes the code here consistent
with other Amlogic pinctrl drivers.

No functional changes since thee "gpio" function is currently not used.

pinctrl: meson: meson8b: fix the GPIO function for the GPIOAO pins

2018-12-21T09:59:03+00:00

The GPIOAO pins (as well as the two exotic GPIO_BSD_EN and GPIO_TEST_N)
only belong to the pin controller in the AO domain. With the current
definition these pins cannot be referred to in .dts files as group
(which is possible on GXBB and GXL for example).

Add a separate "gpio_aobus" function to fix the mapping between the pin
controller and the GPIO pins in the AO domain. This is similar to how
the GXBB and GXL drivers implement this functionality.

pinctrl: meson: fix pull enable register calculation

2018-11-19T14:40:55+00:00

We just changed the code so we apply bias disable on the correct
register but forgot to align the register calculation. The result
is that we apply the change on the correct register, but possibly
at the incorrect offset/bit

This went undetected because offsets tends to be the same between
REG_PULL and REG_PULLEN for a given pin the EE controller. This
is not true for the AO controller.

pinctrl: meson-gxl: remove invalid GPIOX tsin_a pins

2018-11-15T09:28:05+00:00

The GPIOX tsin_a pins wrongly uses the SDCard pinctrl bits, this
patch completely removes these pins entries until we find out what
are the correct bits and registers to be used instead.
