Revert "drm: Make drivers depends on DRM_DW_HDMI"

2024-06-12T09:39:57+00:00

commit 8f7f115596d3dccedc06f5813e0269734f5cc534 upstream. This reverts commit c0e0f139354c01e0213204e4a96e7076e5a3e396, as helper code should always be selected by the driver that needs it, for the convenience of the final user configuring a kernel. The user who configures a kernel should not need to know which helpers are needed for the driver he is interested in. Making a driver depend on helper code means that the user needs to know which helpers to enable first, which is very user-unfriendly.

drm/bridge: imx: Fix unmet depenency for PHY_FSL_SAMSUNG_HDMI_PHY

2024-06-12T09:39:30+00:00

[ Upstream commit cbdbd9ca718e6efbc77b97ddf0b19b0cd46ac36c ] When enabling i.MX8MP DWC HDMI driver, it automatically selects PHY_FSL_SAMSUNG_HDMI_PHY, since it wont' work without the phy. This may cause some Kconfig warnings during various build tests. Fix this by implying the phy instead of selecting the phy. To prevent this from happening with the DRM_IMX8MP_HDMI_PVI, also imply it instead of selecting it.

drm: Make drivers depends on DRM_DW_HDMI

2024-06-12T09:39:30+00:00

[ Upstream commit c0e0f139354c01e0213204e4a96e7076e5a3e396 ] DRM_DW_HDMI has a number of dependencies that might not be enabled. However, drivers were used to selecting it while not enforcing the DRM_DW_HDMI dependencies. This could result in Kconfig warnings (and further build breakages) such as: Kconfig warnings: (for reference only) WARNING: unmet direct dependencies detected for DRM_DW_HDMI Depends on [n]: HAS_IOMEM [=y] && DRM [=m] && DRM_BRIDGE [=y] && DRM_DISPLAY_HELPER [=n] Selected by [m]: - DRM_SUN8I_DW_HDMI [=m] && HAS_IOMEM [=y] && DRM_SUN4I [=m] Reported-by: kernel test robot Closes: https://lore.kernel.org/oe-kbuild-all/202403262127.kZkttfNz-lkp@intel.com/ Acked-by: Jani Nikula Link: https://lore.kernel.org/r/20240327-kms-kconfig-helpers-v3-7-eafee11b84b3@kernel.org Signed-off-by: Maxime Ripard Stable-dep-of: cbdbd9ca718e ("drm/bridge: imx: Fix unmet depenency for PHY_FSL_SAMSUNG_HDMI_PHY") Signed-off-by: Sasha Levin

drm/bridge: imx: add driver for HDMI TX Parallel Video Interface

2024-02-05T11:16:44+00:00

This IP block is found in the HDMI subsystem of the i.MX8MP SoC. It has a full timing generator and can switch between different video sources. On the i.MX8MP however the only supported source is the LCDIF. The block just needs to be powered up and told about the polarity of the video sync signals to act in bypass mode.

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.
