2020-07-08gpio: gpio-sama5d2-piobu: Demote all kerneldoc headers to basic comment blocksLee Jones1-8/+8
No attempt has been made to provide proper descriptions for each of the function arguments throughout the file. Simply demote all kerneldoc headers to basic function headers. Fixes the following W=1 kernel build warnings: drivers/gpio/gpio-sama5d2-piobu.c:59: warning: Function parameter or member 'chip' not described in 'sama5d2_piobu_setup_pin' drivers/gpio/gpio-sama5d2-piobu.c:59: warning: Function parameter or member 'pin' not described in 'sama5d2_piobu_setup_pin' drivers/gpio/gpio-sama5d2-piobu.c:81: warning: Function parameter or member 'chip' not described in 'sama5d2_piobu_write_value' drivers/gpio/gpio-sama5d2-piobu.c:81: warning: Function parameter or member 'pin' not described in 'sama5d2_piobu_write_value' drivers/gpio/gpio-sama5d2-piobu.c:81: warning: Function parameter or member 'mask' not described in 'sama5d2_piobu_write_value' drivers/gpio/gpio-sama5d2-piobu.c:81: warning: Function parameter or member 'value' not described in 'sama5d2_piobu_write_value' drivers/gpio/gpio-sama5d2-piobu.c:97: warning: Function parameter or member 'chip' not described in 'sama5d2_piobu_read_value' drivers/gpio/gpio-sama5d2-piobu.c:97: warning: Function parameter or member 'pin' not described in 'sama5d2_piobu_read_value' drivers/gpio/gpio-sama5d2-piobu.c:97: warning: Function parameter or member 'mask' not described in 'sama5d2_piobu_read_value' drivers/gpio/gpio-sama5d2-piobu.c:116: warning: Function parameter or member 'chip' not described in 'sama5d2_piobu_get_direction' drivers/gpio/gpio-sama5d2-piobu.c:116: warning: Function parameter or member 'pin' not described in 'sama5d2_piobu_get_direction' drivers/gpio/gpio-sama5d2-piobu.c:131: warning: Function parameter or member 'chip' not described in 'sama5d2_piobu_direction_input' drivers/gpio/gpio-sama5d2-piobu.c:131: warning: Function parameter or member 'pin' not described in 'sama5d2_piobu_direction_input' drivers/gpio/gpio-sama5d2-piobu.c:140: warning: Function parameter or member 'chip' not described in 'sama5d2_piobu_direction_output' drivers/gpio/gpio-sama5d2-piobu.c:140: warning: Function parameter or member 'pin' not described in 'sama5d2_piobu_direction_output' drivers/gpio/gpio-sama5d2-piobu.c:140: warning: Function parameter or member 'value' not described in 'sama5d2_piobu_direction_output' drivers/gpio/gpio-sama5d2-piobu.c:154: warning: Function parameter or member 'chip' not described in 'sama5d2_piobu_get' drivers/gpio/gpio-sama5d2-piobu.c:154: warning: Function parameter or member 'pin' not described in 'sama5d2_piobu_get' drivers/gpio/gpio-sama5d2-piobu.c:174: warning: Function parameter or member 'chip' not described in 'sama5d2_piobu_set' drivers/gpio/gpio-sama5d2-piobu.c:174: warning: Function parameter or member 'pin' not described in 'sama5d2_piobu_set' drivers/gpio/gpio-sama5d2-piobu.c:174: warning: Function parameter or member 'value' not described in 'sama5d2_piobu_set' Signed-off-by: Lee Jones <lee.jones@linaro.org> Acked-by: Ludovic Desroches <ludovic.desroches@microchip.com> Cc: Ludovic Desroches <ludovic.desroches@microchip.com> Cc: Andrei Stefanescu <andrei.stefanescu@microchip.com> Link: https://lore.kernel.org/r/20200630133345.2232932-6-lee.jones@linaro.org Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
2019-12-12gpio: remove unneeded MODULE_VERSION() usageEnrico Weigelt, metux IT consult1-1/+0
Remove MODULE_VERSION(), as it isn't needed at all: the only version making sense is the kernel version. Signed-off-by: Enrico Weigelt, metux IT consult <info@metux.net> Signed-off-by: Bartosz Golaszewski <bgolaszewski@baylibre.com>
2019-11-07gpio: Use new GPIO_LINE_DIRECTIONMatti Vaittinen1-3/+4
It's hard for occasional GPIO code reader/writer to know if values 0/1 equal to IN or OUT. Use defined GPIO_LINE_DIRECTION_IN and GPIO_LINE_DIRECTION_OUT to help them out. NOTE - for gpio-amd-fch and gpio-bd9571mwv: This commit also changes the return value for direction get to equal 1 for direction INPUT. Prior this commit these drivers might have returned some other positive value but 1 for INPUT.

2019-01-11gpio: sama5d2-piobu: Set proper output level for direction_outputAxel Lin1-12/+8
Set proper output level base on the argument of direction_output. Also remove sama5d2_piobu_set_direction() as there is only one caller now. Signed-off-by: Axel Lin <axel.lin@ingics.com> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
2018-12-21gpio: add driver for SAMA5D2 PIOBU pinsAndrei.Stefanescu@microchip.com1-0/+253
PIOBU pins do not lose their voltage during Backup/Self-refresh. This patch adds a simple GPIO controller for them and a maintainer for the driver. This driver adds support for using the pins as GPIO offering the possibility to read/set the voltage.
