drm/imx/lcdc: Fix double-free of driver data

2024-01-25T23:35:33+00:00

[ Upstream commit ff3670877e7c73d06c2a835d9abb62efcae0145c ] The struct imx_lcdc driver data is allocated using devm_drm_dev_alloc() so it must not be explicitly kfree()d. Also drm_kms_helper_poll_fini() should not be called as there is no matching drm_kms_helper_poll_init(). So drop the release function completely.

drm/imx/ipuv3: ipuv3-plane: reuse local variable height in atomic_update

2023-07-28T15:25:31+00:00

Use the already existing local variable height = drm_rect_height() >> 16 to replace other occurrences of the same value.

drm/imx/ipuv3: Fix front porch adjustment upon hactive aligning

2023-07-28T15:20:26+00:00

When hactive is not aligned to 8 pixels, it is aligned accordingly and hfront porch needs to be reduced the same amount. Unfortunately the front porch is set to the difference rather than reducing it. There are some Samsung TVs which can't cope with a front porch of instead of 70.

drm: Explicitly include correct DT includes

2023-07-21T07:12:43+00:00

The DT of_device.h and of_platform.h date back to the separate of_platform_bus_type before it as merged into the regular platform bus. As part of that merge prepping Arm DT support 13 years ago, they "temporarily" include each other. They also include platform_device.h and of.h. As a result, there's a pretty much random mix of those include files used throughout the tree. In order to detangle these headers and replace the implicit includes with struct declarations, users need to explicitly include the correct includes.
