I get a compile error here:
drivers/staging/imx-drm/imx-ldb.c: In function ‘imx_ldb_encoder_disable’:
drivers/staging/imx-drm/imx-ldb.c:283:2: error: implicit declaration of

Adding #include <linux/gpio.h> fixes that but gives another error:
drivers/staging/imx-drm/imx-ldb.c: In function ‘imx_ldb_encoder_disable’:
drivers/staging/imx-drm/imx-ldb.c:284:30: error: ‘struct
imx_ldb_channel’ has no member named ‘enable_gpio’
drivers/staging/imx-drm/imx-ldb.c:285:28: error: ‘struct
imx_ldb_channel’ has no member named ‘enable_gpio’
Commenting out the block gives a working driver.

Martin
