Revert "drm: Make drivers depends on DRM_DW_HDMI"

2024-05-02T15:59:59+00:00

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/imx: Add drm_panic support

2024-04-15T14:14:07+00:00

Add support for the drm_panic module, which displays a user-friendly message to the screen when a kernel panic occurs. v7: * use drm_panic_gem_get_scanout_buffer() helper v8: * Replace get_scanout_buffer() logic with drm_panic_set_buffer() v9: * Revert to using get_scanout_buffer() (Sima) * move get_scanout_buffer() to plane helper functions v12: * Rename drm_panic_gem_get_scanout_buffer to drm_fb_dma_get_scanout_buffer (Thomas Zimmermann) Signed-off-by: Jocelyn Falempe Link: https://patchwork.freedesktop.org/patch/msgid/20240409163432.352518-9-jfalempe@redhat.com Acked-by: Daniel Vetter

drm: Make drivers depends on DRM_DW_HDMI

2024-03-28T10:26:49+00:00

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

drm/imx/ipuv3: do not return negative values from .get_modes()

2024-03-13T08:44:14+00:00

The .get_modes() hooks aren't supposed to return negative error codes. Return 0 for no modes, whatever the reason.

drm/imx/dcss: fix resource size calculation

2024-02-28T09:16:59+00:00

The resource is inclusive of the ->start and ->end addresses so this calculation is not correct. It should be "res->end - res->start + 1". Use the resource_size() to do the calculation.

drm/imx/dcss: have all init functions use devres

2024-02-02T13:36:21+00:00

dcss currently allocates and ioremaps quite a few resources in its probe function's call graph. Devres now provides convenient functions which perform the same task but do the cleanup automatically. Port all memory allocations and ioremap() calls to the devres counterparts.

drm/imx/dcss: request memory region

2024-02-02T13:34:40+00:00

The driver's memory regions are currently just ioremap()ed, but not reserved through a request. That's not a bug, but having the request is a little more robust. Implement the region-request through the corresponding managed devres-function.

drm/imx: prefer snprintf over sprintf

This will trade the W=1 warning -Wformat-overflow to -Wformat-truncation. This lets us enable -Wformat-overflow subsystem wide.

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

2023-12-01T15:04:14+00:00

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.
