gpio: syscon: Remove usage of syscon_regmap_lookup_by_compatible

2022-05-02T08:41:33+00:00

Since version 5.13, the standard syscon bindings have been added to all clps711x DT nodes, so we can now use the more general syscon_regmap_lookup_by_phandle function to get the syscon pointer. This patch removes the usage of the syscon_regmap_lookup_by_compatible function as it is no longer used in the driver.

gpio: gpio-syscon: Fix formatting issues which confuse kerneldoc

2020-07-08T07:24:08+00:00

Kerneldoc expects struct properties to be documented using the syntax '@.*: ', but no '@' has been provided in 'struct syscon_gpio_data's header. Add them to stop confusing kerneldoc. Fixes the following W=1 warnings: drivers/gpio/gpio-syscon.c:48: warning: Function parameter or member 'compatible' not described in 'syscon_gpio_data' drivers/gpio/gpio-syscon.c:48: warning: Function parameter or member 'flags' not described in 'syscon_gpio_data' drivers/gpio/gpio-syscon.c:48: warning: Function parameter or member 'bit_count' not described in 'syscon_gpio_data' drivers/gpio/gpio-syscon.c:48: warning: Function parameter or member 'dat_bit_offset' not described in 'syscon_gpio_data' drivers/gpio/gpio-syscon.c:48: warning: Function parameter or member 'dir_bit_offset' not described in 'syscon_gpio_data' drivers/gpio/gpio-syscon.c:48: warning: Function parameter or member 'set' not described in 'syscon_gpio_data' Signed-off-by: Lee Jones Cc: Alexander Shiyan Link: https://lore.kernel.org/r/20200630133345.2232932-7-lee.jones@linaro.org Signed-off-by: Linus Walleij

gpio: syscon: Fix possible NULL ptr usage

2018-10-10T08:33:11+00:00

The priv->data->set can be NULL while flags contains GPIO_SYSCON_FEAT_OUT and chip->set is valid pointer. This happens in case the controller uses the default GPIO setter. Always use chip->set to access the setter to avoid possible NULL pointer dereferencing. Signed-off-by: Marek Vasut Signed-off-by: Linus Walleij

gpio: syscon: rockchip: add GRF GPIO support for rk3328

2018-08-06T21:46:55+00:00

In Rockchip RK3328, the output only GPIO_MUTE pin, originally for codec mute control, can also be used for general purpose. It is manipulated by the GRF_SOC_CON10 register in GRF. Aside from the GPIO_MUTE pin, the HDMI pins can also be set in the same way. Currently this GRF GPIO controller only supports the mute pin. If needed in the future, the HDMI pins support can also be added. Signed-off-by: Levin Du Reviewed-by: Rob Herring Reviewed-by: Heiko Stuebner Signed-off-by: Linus Walleij

gpio: syscon: allow fetching syscon from parent node

2018-05-23T08:07:26+00:00

Syscon nodes can be a simple-mfd and the syscon-users then be declared as children of this node. That way the parent-child structure can be better represented for devices that are fully embedded in the syscon. Therefore allow getting the syscon from the parent if neither a special compatible nor a gpio,syscon-dev property is defined.
