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.

2017-08-14gpio: Add support for TPS68470 GPIOsRajmohan Mani
This patch adds support for TPS68470 GPIOs. There are 7 GPIOs and a few sensor related GPIOs. These GPIOs can be requested and configured as appropriate. The GPIOs are also provided with descriptive names. However, the typical use case is that the OS GPIO driver will interact with TPS68470 GPIO driver to configure these GPIOs, as requested by the platform firmware.
