2023-01-10drm/debugfs: use octal permissions instead of symbolic permissionsMaíra Canal
Currently, debugfs functions are using symbolic macros as permission bits, but checkpatch reinforces permission bits in the octal form, as they are more readable and easier to understand [1]. Moreover, using the symbolic macro S_IFREG is redundant. Therefore, use octal permission bits in all debugfs functions.

2023-01-10drm/mxsfb: improve clk handling for axi clkUwe Kleine-König
Ignoring errors from devm_clk_get() is wrong. To handle not all platforms having an axi clk use devm_clk_get_optional() instead and do proper error handling. Also the clk API handles NULL as a dummy clk (which is also returned by devm_clk_get_optional() if there is no clk) so there is no need to check for NULL before calling clk_prepare_enable() or its counter part.

This commit fixes vertical timings of the VEC (composite output) modes to accurately represent the 525-line ("NTSC") and 625-line ("PAL") ITU-R standards. Previous timings were actually defined as 502 and 601 lines, resulting in non-standard 62.69 Hz and 52 Hz signals being generated, respectively. Changes to vc4_crtc.c have also been made, to make the PixelValve vertical timings accurately correspond to the DRM modeline in interlaced modes.

2023-01-05drm/bridge_connector: rely on drm_kms_helper_poll_* for HPD enablementDmitry Baryshkov
Use drm_connector's helpers enable_hpd and disable_hpd to enable and disable HPD automatically by the means of drm_kms_helper_poll_* functions. As the drm_bridge_connector_enable_hpd() and drm_bridge_connector_disable_hpd() functions are now unused, replace them with stubs to ease driver migration. Enabling the HPD from drm_bridge_connector_init() can happen too early, before the driver is prepared to handle HPD events. As the drm_bridge_connector_enable_hpd() is empty anyway, drop this call anyway.

2023-01-05drm/probe-helper: enable and disable HPD on connectorsDmitry Baryshkov
Introduce two drm_connector_helper_funcs: enable_hpd() and disable_hpd(). They are called by drm_kms_helper_poll_enable() and drm_kms_helper_poll_disable() (and thus drm_kms_helper_poll_init() and drm_kms_helper_poll_fini()) respectively. This allows DRM drivers to rely on drm_kms_helper_poll for enabling and disabling HPD detection rather than doing that manually.

2023-01-05drm/bridge: panel: Prevent ERR_PTR DereferenceMaxime Ripard
Commit 5ea6b1702781 ("drm/panel: Add prepare_prev_first flag to drm_panel") introduced an access to the bridge pointer in the devm_drm_panel_bridge_add_typed() function. However, due to the unusual ERR_PTR check when getting that pointer, the pointer access is done even though the pointer might be an error pointer. Rework the function for a more traditional design that will return immediately if it gets an ERR_PTR so that we never access the pointer in that case.
