pinctrl: sunxi: sun50i-h5 use platform_irq_count

2020-01-07T08:55:33+00:00

platform_irq_count() is the more generic way (independent of device trees) to determine the count of available interrupts. So use this instead. As platform_irq_count() might return an error code (which of_irq_count doesn't) some additional handling is necessary.

pinctrl: use devm_platform_ioremap_resource() to simplify code

2019-11-05T14:33:40+00:00

devm_platform_ioremap_resource() internally have platform_get_resource() and devm_ioremap_resource() in it. So instead of calling them separately use devm_platform_ioremap_resource() directly.

pinctrl: sunxi: v3s: introduce support for V3

pinctrl: sunxi: Support I/O bias voltage setting on H6

2019-04-23T10:31:42+00:00

H6 SoC has a "pio group withstand voltage mode" register (datasheet description), that needs to be used to select either 1.8V or 3.3V I/O mode, based on what voltage is powering the respective pin banks and is thus used for I/O signals. Add support for configuring this register according to the voltage of the pin bank regulator (if enabled). This is similar to the support for I/O bias voltage setting patch for A80 and the same concerns apply.

pinctrl: sunxi: Prepare for alternative bias voltage setting methods

H6 has a different I/O voltage bias setting method than A80. Prepare existing code for using alternative bias voltage setting methods. Signed-off-by: Ondrej Jirman Acked-by: Maxime Ripard Signed-off-by: Linus Walleij

pinctrl: sunxi: Allow to disable pinctrl drivers

2019-04-04T03:55:54+00:00

Our pinctrl drivers are consisting of some common code, and big pin tables that are SoC-specific. This is fine in most cases, but when you want to reduce the size of the particular kernel image, those big tables are, well, quite big. We haven't had the option to disable them in the past since they were hidden Kconfig options based on the SoC support. However, that granularity isn't great since we don't have one Kconfig option per-SoC, but rather one by family. Make those options selectable by the user so that they can disable it if needed, while keeping the current default to not change the standard case.

pinctrl: sunxi: Declare set_config on the GPIO chip

2019-04-04T03:54:59+00:00

Our pin controller can configure the pins no matter how they are muxed, so it makes sense to allow this for GPIOs as well. Add the generic set_config function so that we can rely on the existing pinctrl code we have. Signed-off-by: Maxime Ripard Acked-by: Chen-Yu Tsai Signed-off-by: Linus Walleij

pinctrl: sunxi: Fix variable assignment syntax

2019-04-04T03:54:55+00:00

Lines are usually ended with a semi-column in C, yet this was copied from a structure declaration to the init variant while keeping the comma at the end. Make sure we have a normal syntax, instead of multiple assignments.

pinctrl: sunxi: implement pin_config_set

2019-04-04T03:54:39+00:00

The sunxi pinctrl only implements the pin_config_group_set callback at the moment, whereas the gpiochip_generic_config function relies on pin_config_set. Rework the functions a little to support pin_config_set, and rely on it for pin_config_group_set. Signed-off-by: Maxime Ripard Acked-by: Chen-Yu Tsai Signed-off-by: Linus Walleij
