2017-02-07	drm/fsl-dcu: check for clk_prepare_enable() error	Fabio Estevam	1	-2/+6
	clk_prepare_enable() may fail, so we should better check its return value. Also place the of_node_put() function right after clk_prepare_enable(), in order to avoid calling of_node_put() twice in case clk_prepare_enable() fails.

2017-02-07	drm/fsl-dcu: remove unneeded 'ret' assignment	Fabio Estevam	1	-3/+1
	When devm_kzalloc() fails there is no need to assign an error code to the 'ret' variable as it will not be used after jumping to the 'err_node_put' label, so just remove the assignment.

2016-09-05	drm/fsl-dcu: use PTR_ERR_OR_ZERO() to simplify the code	Wei Yongjun	1	-4/+1
	Use PTR_ERR_OR_ZERO rather than if(IS_ERR(...)) + PTR_ERR. Generated by: scripts/coccinelle/api/ptr_ret.cocci Signed-off-by: Wei Yongjun <weiyj.lk@gmail.com> Signed-off-by: Stefan Agner <stefan@agner.ch>
2016-07-15	drm/fsl-dcu: add missing of_node_put after calling of_parse_phandle	Peter Chen	1	-0/+1
	of_node_put needs to be called when the device node which is got from of_parse_phandle has finished using, but current code only calls it at error path, fix it by adding it at correct code path. Signed-off-by: Peter Chen <peter.chen@nxp.com> Signed-off-by: Stefan Agner <stefan@agner.ch>
2016-04-25	drm/fsl-dcu: add TCON driver	Stefan Agner	1	-0/+111
	Add driver for the TCON (timing controller) module. The TCON module is a separate module attached after the DCU (display controller unit). Each DCU instance has its own, directly connected TCON instance. The DCU's RGB and timing signals are passing through the TCON module. TCON can provide timing signals for raw TFT panels or operate in a bypass mode which leaves all signals unaltered. The driver currently only supports the bypass mode.
