2019-11-07gpio: Use new GPIO_LINE_DIRECTIONMatti Vaittinen
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.

2019-08-05gpio: madera: Add support for Cirrus Logic CS47L92Charles Keepax
As the gpio is common to all madera codecs all that is needed is to setup the correct number of GPIO pins for the CS47L92.

GPL-2.0-only is the preferred way of expressing v2 of the GPL, so switch to that and remove some redundant copyright notices. Signed-off-by: Charles Keepax <ckeepax@opensource.cirrus.com> Signed-off-by: Bartosz Golaszewski <bgolaszewski@baylibre.com>

2018-06-05gpio: madera: Support Cirrus Logic Madera class codecsRichard Fitzgerald
This adds support for the GPIOs on Cirrus Logic Madera class codecs. Any pins not used for special functions (see the pinctrl driver) can be used as general single-bit input or output lines. The number of available GPIOs varies between codecs. Note that this is part of a composite MFD for these codecs and can only be used with the corresponding MFD and other child drivers on those silicon. The GPIO block on these codecs does not exist indepedently of the rest of the MFD.
