drm: Pass 'name' to drm_encoder_init()

Done with coccinelle for the most part.

drm/tilcdc: panel: make better use of gpiod API

2015-07-06T08:10:21+00:00

Since 39b2bbe3d715 (gpio: add flags argument to gpiod_get*() functions) which appeared in v3.17-rc1, the gpiod_get* functions take an additional parameter that allows to specify direction and initial value for output. Furthermore there is devm_gpiod_get_optional which is designed to get optional gpios. Simplify driver accordingly. Acked-by: Alexandre Courbot Acked-by: Linus Walleij Signed-off-by: Uwe Kleine-König

drm/tilcdc: panel: Add support for enable GPIO

2014-09-17T00:55:27+00:00

In order to support the "enable GPIO" available in many panel devices, this commit adds a proper devicetree binding. By providing an enable GPIO in the devicetree, the driver can now turn off and on the panel device, and/or the backlight device. Both the backlight and the GPIO are optional properties.

drm/tilcdc: panel: Set return value explicitly

2014-09-17T00:55:19+00:00

Instead of setting an initial value for the return code, set it explicitly on each error path. This is just a cosmetic cleanup, as preparation for the enable GPIO support. Tested-by: Darren Etheridge Tested-by: Johannes Pointner Signed-off-by: Ezequiel Garcia Signed-off-by: Dave Airlie

drm/tilcdc: panel: Fix backlight devicetree support

2014-09-17T00:55:10+00:00

The current backlight support is broken; the driver expects a backlight-class in the panel devicetree node. Fix this by implementing it properly, getting an optional backlight from a phandle. This shouldn't cause any backward-compatibility DT issue because the current implementation doesn't work and is not even documented.

drm/tilcdc: panel: Use devm_kzalloc to simplify the error path
