drm/imx: Don't set a gamma table size

2016-03-31T09:24:37Z

imx doesn't have any functions for setting the gamma table, so this is completely defunct. Not nice to lie to userspace, so let's stop! Cc: Russell King Signed-off-by: Daniel Vetter Signed-off-by: Philipp Zabel

drm/imx: ipuv3-plane: Configure DMFC wait4eot bit after slots are determined

2016-03-31T09:24:35Z

Just as the function ipu_dmfc_config_wait4eot() tells, the DMFC wait4eot bit depends on the number of DMFC slots to be used, so it should be called after the slots are determined in the function ipu_dmfc_alloc_bandwidth(). Based on tests, this patch may eliminate display distortion issue on overlay plane with small resolutions. To reproduce the issue, we may run this drm modetest case - 'modetest -P 19:64x64'.

gpu: ipu-v3: ipu-dmfc: Rename ipu_dmfc_init_channel to ipu_dmfc_config_wait4eot

2016-03-31T09:24:33Z

The function name 'ipu_dmfc_config_wait4eot' matches the implementation of the function better than 'ipu_dmfc_init_channel', since it only touches the wait4eot bits. Signed-off-by: Liu Ying Signed-off-by: Philipp Zabel

gpu: ipu-v3: ipu-dmfc: Make function ipu_dmfc_init_channel() return void

2016-03-31T09:24:31Z

Since the function ipu_dmfc_init_channel() always returns zero, we may change the return type to void to simplify the code. Signed-off-by: Liu Ying Signed-off-by: Philipp Zabel

drm/imx: dw_hdmi: Don't call platform_set_drvdata()

2016-03-31T09:24:28Z

The IMX dw_hdmi driver just called platform_set_drvdata() to get your hopes up that maybe, somehow, you'd be able to retrieve the 'struct imx_hdmi' from a pointer to the 'struct device'. You can't. When we call dw_hdmi_bind() the main driver calls dev_set_drvdata(), which clobbers our setting. Let's just remove the platform_set_drvdata() to avoid dashing people's hopes.

drm/imx: dw_hdmi: Call drm_encoder_cleanup() in error path

2016-03-31T09:24:26Z

The drm_encoder_cleanup() was missing both from the error path of dw_hdmi_imx_bind(). This caused a crash when slub_debug was enabled and we ended up deferring probe of HDMI at boot. This call isn't needed from unbind() because if dw_hdmi_bind() returns no error then it takes over the job of freeing the encoder (in dw_hdmi_unbind).

drm/imx: ipuv3-plane: fix planar YUV 4:2:0 support

2016-03-31T09:23:32Z

The driver already advertises multi-planar YUV support, but previously the U/V offset and stride setup was missing. Signed-off-by: Philipp Zabel

drm/imx: ipuv3-plane: Add more thorough checks for plane parameter limitations

2016-03-31T09:23:31Z

The IPU addresses multiplanar formats using a base address and relative offsets for the secondary planes. Since those offsets must be positive and not too large, and none of the plane parameters except the base address may be changed while scanout is active, store the pitches and u/v offsets and check all values against IDMAC limitations.

Merge drm-fixes into drm-next.

Nouveau wanted this to avoid some worse conflicts when I merge that.
