pinctrl: update direction_output function of cherryview driver

2015-03-10T08:02:23Z

From the comments of gpiod_direction_output(), need to set @value as initial output, so update the lowlevel routine to make it work. Signed-off-by: jason.cj.chen Signed-off-by: qipeng.zha Acked-by: Mika Westerberg Signed-off-by: Linus Walleij

pinctrl: cherryview: Configure HiZ pins to be input when requested as GPIOs

2015-02-04T08:59:26Z

If the pin is in HiZ mode when it is requested as GPIO its value cannot be read (it always returns 0). In order to cope with the Linux GPIO subsystem where we do not have such state at all, turn the pin to be input instead.

pinctrl: intel: drop owner assignment from platform_drivers

2015-01-10T21:47:23Z

This platform_driver does not need to set an owner, it will be populated by the driver core. Signed-off-by: Wolfram Sang Acked-by: Mika Westerberg Signed-off-by: Linus Walleij

pinctrl: cherryview: Save and restore pin configs over system sleep

2015-01-10T21:47:22Z

Before resuming from system sleep BIOS restores its view of pin configuration. If we have configured some pins differently from that, for instance some driver requested a pin as a GPIO but it was not in GPIO mode originally, our view of the pin configuration will not match the hardware state anymore. This patch saves the pin configuration and interrupt mask registers on suspend and restores them on exit. This should make sure that the previously configured state is still in effect.

pinctrl: Add Intel Cherryview/Braswell pin controller support

2014-11-04T10:21:02Z

This driver supports the pin/GPIO controllers found in newer Intel SoCs like Cherryview and Braswell. The driver provides full GPIO support and minimal set of pin controlling funtionality. The driver is based on the original Cherryview GPIO driver authored by Ning Li and Alan Cox. Signed-off-by: Mika Westerberg Signed-off-by: Linus Walleij
