mfd: remove ucb1400 support

2023-02-01T16:23:38+00:00

The ucb1400 MFD driver and its gpio and touchscreen child drivers were only used on a few PXA machines that were unused for a while and are now removed. Removing these leaves the AC97 support as ALSA specific, no other drivers are now connected through this interface.

gpio: ucb1400: Use proper header

2022-08-31T11:37:32+00:00

The UCB1400 implements a GPIO driver so it needs to include the header, not the legacy header. Compile tested on pxa_defconfig. Signed-off-by: Linus Walleij Signed-off-by: Bartosz Golaszewski

gpio: ucb1400: Remove platform setup and teardown support

2022-07-19T07:56:51+00:00

There is no user of these callbacks. The motivation for this change is to stop returning an error code from the remove callback. This is a preparation for making platform remove callbacks return void. Signed-off-by: Uwe Kleine-König Signed-off-by: Bartosz Golaszewski

gpio: ucb1400: use gpiochip data pointer

2016-01-05T10:21:17+00:00

This makes the driver use the data pointer added to the gpio_chip to store a pointer to the state container instead of relying on container_of(). Signed-off-by: Linus Walleij

gpio: ucb1400: Be sure to clamp return value

2015-12-26T21:28:30+00:00

As we want gpio_chip .get() calls to be able to return negative error codes and propagate to drivers, we need to go over all drivers and make sure their return values are clamped to [0,1]. We do this by using the ret = !!(val) design pattern. Signed-off-by: Linus Walleij
