gpu: ipu-v3: ipu-ic: Fix saturation bit offset in TPMEM

2019-08-04T07:34:52+00:00

commit 3d1f62c686acdedf5ed9642b763f3808d6a47d1e upstream. The saturation bit was being set at bit 9 in the second 32-bit word of the TPMEM CSC. This isn't correct, the saturation bit is bit 42, which is bit 10 of the second word.

gpu: ipu-v3: dp: fix CSC handling

2019-05-16T17:45:07+00:00

[ Upstream commit d4fad0a426c6e26f48c9a7cdd21a7fe9c198d645 ] Initialize the flow input colorspaces to unknown and reset to that value when the channel gets disabled. This avoids the state getting mixed up with a previous mode. Also keep the CSC settings for the background flow intact when disabling the foreground flow.

gpu: ipu-v3: Fix CSI offsets for imx53

[ Upstream commit bb867d219fda7fbaabea3314702474c4eac2b91d ] The CSI offsets are wrong for both CSI0 and CSI1. They are at physical address 0x1e030000 and 0x1e038000 respectively.

[ Upstream commit 2c0408dd0d8906b26fe8023889af7adf5e68b2c2 ] The CSI0/CSI1 registers offset is at +0xe030000/+0xe038000 relative to the control module registers on IPUv3EX.

drm/imx: Match imx-ipuv3-crtc components using device node in platform data

2016-06-08T01:14:37+00:00

commit 310944d148e3600dcff8b346bee7fa01d34903b1 upstream. The component master driver imx-drm-core matches component devices using their of_node. Since commit 950b410dd1ab ("gpu: ipu-v3: Fix imx-ipuv3-crtc module autoloading"), the imx-ipuv3-crtc dev->of_node is not set during probing. Before that, of_node was set and caused an of: modalias to be used instead of the platform: modalias, which broke module autoloading. On the other hand, if dev->of_node is not set yet when the imx-ipuv3-crtc probe function calls component_add, component matching in imx-drm-core fails. While dev->of_node will be set once the next component tries to bring up the component master, imx-drm-core component binding will never succeed if one of the crtc devices is probed last. Add of_node to the component platform data and match against the pdata->of_node instead of dev->of_node in imx-drm-core to work around this problem.

gpu: ipu-v3: Fix imx-ipuv3-crtc module autoloading

2016-05-11T09:21:21+00:00

commit 503fe87bd0a8346ba9d8b7f49115dcd0a4185226 upstream. If of_node is set before calling platform_device_add, the driver core will try to use of: modalias matching, which fails because the device tree nodes don't have a compatible property set. This patch fixes imx-ipuv3-crtc module autoloading by setting the of_node property only after the platform modalias is set.

gpu: ipu-v3: Assign of_node of child platform devices to corresponding ports

2015-11-24T10:30:17+00:00

The crtc child device driver shouldn't have to modify the of_node of its platform device in the probe function. Instead, let the IPU core driver set the of_node when the platform device is created. Also reorder the client_reg array so the elements are in port id order (CSIs first, then DIs). Suggested-by: Russell King Signed-off-by: Philipp Zabel Acked-by: Russell King
