pinctrl/meson: enable building as modules

2020-11-05T13:51:38+00:00

Enable pinctrl drivers for 64-bit Amlogic SoCs to be built as modules.

The default is still built-in, this only adds the option of building
as modules.

pinctrl: meson: pinctrl-meson-a1: Remove unused const variable 'i2c_slave_groups'

It has never been used.

Fixes the following W=1 kernel build warning(s):

pinctrl: meson: fix drive strength register and bit calculation

2020-07-07T11:15:11+00:00

If a GPIO bank has greater than 16 pins, PAD_DS_REG is split into two
or more registers. However, when register and bit were calculated, the
first register defined in the bank was used, and the bit was calculated
based on the first pin. This causes problems in setting the driving
strength.

The following method was used to solve this problem:
A bit is calculated first using predefined strides. Then, If the bit is
32 or more, the register is changed by the quotient of the bit divided
by 32. And the bit is set to the remainder.

pinctrl: meson: wire up the gpio_chip's set_config callback

2020-04-28T10:00:46+00:00

Use gpiochip_generic_config for the gpio_chip's set_config callback so
GPIO flags like GPIO_PULL_UP or GPIO_PULL_DOWN can be used in the board
.dts descriptions.
This is required for some Meson8m2 boards where GPIO_BSD_EN provides the
"MUTE" signal and requires enabling the internal pull-up resistor.

pinctrl: meson: implement the gpio_chip get_direction callback

2020-04-28T10:00:46+00:00

Implement the get_direction callback so we read the direction from the
actual GPIO controller register. This is recommended by the gpio_chip
kernel doc.

Merge tag 'pinctrl-v5.7-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl

2020-04-02T22:47:18+00:00

Pull pin control updates from Linus Walleij:
"This is the bulk of pin control changes for the v5.7 kernel cycle.

There are no core changes this time, only driver developments:

- New driver for the Dialog Semiconductor DA9062 Power Management
Integrated Circuit (PMIC).

- Renesas SH-PFC has improved consistency, with group and register
checks in the configuration checker.

- New subdriver for the Qualcomm IPQ6018.

- Add the RGMII pin control functionality to Qualcomm IPQ8064.

- Performance and code quality cleanups in the Mediatek driver.

- Improve the Broadcom BCM2835 support to cover all the GPIOs that
exist in it.

- The Allwinner/Sunxi driver properly masks non-wakeup IRQs on
suspend.

- Add some missing groups and functions to the Ingenic driver.

- Convert some of the Freescale device tree bindings to use the new
and all improved JSON YAML markup.

- Refactorings and support for the SFIO/GPIO in the Tegra194 SoC
driver.

- Support high impedance mode in the Spreadtrum/Unisoc driver"

pinctrl: meson-gxl: fix GPIOX sdio pins

2020-02-21T15:28:16+00:00

In the gxl driver, the sdio cmd and clk pins are inverted. It has not caused
any issue so far because devices using these pins always take both pins
so the resulting configuration is OK.
