drm: sti: fix spelling mistake: rejec -> rejection

2022-04-07T08:51:11+00:00

In other places of the driver the string hdmi_rejection_pll is used instead of the truncated hdmi_rejec_pll, so use this string instead to be consistent.

drm/sti: plane: Remove redundant zpos initialisation

2022-02-25T16:57:05+00:00

The sti KMS driver will call drm_plane_create_zpos_property() with an init value depending on the plane type. Since the initial value wasn't carried over in the state, the driver had to set it again in sti_plane_reset(). However, the helpers have been adjusted to set it properly at reset, so this is not needed anymore.

drm/sti: Add support for the nomodeset kernel parameter

2022-01-27T18:15:50+00:00

According to disable Documentation/admin-guide/kernel-parameters.txt, this parameter can be used to disable kernel modesetting. DRM drivers will not perform display-mode changes or accelerated rendering and only the system framebuffer will be available if it was set-up. But only a few DRM drivers currently check for nomodeset, make this driver to also support the command line parameter.

Link drm_fb_cma_helper.o into drm_cma_helper.ko if CONFIG_DRM_KMS_HELPER has been set. Remove CONFIG_DRM_KMS_CMA_HELPER config option. Selecting KMS helpers and CMA will now automatically enable CMA KMS helpers. Some drivers' Kconfig files did not correctly select KMS or CMA helpers. Fix this as part of the change.

drm/bridge: Centralize error message when bridge attach fails

Being informed of a failure to attach a bridge is useful, and many drivers prints an error message in that case. Move the message to drm_bridge_attach() to avoid code duplication. Suggested-by: Stephen Boyd Signed-off-by: Laurent Pinchart Reviewed-by: Tomi Valkeinen Reviewed-by: Jyri Sarha
