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.

Add support for the 1080x2400 Visionox VTDR6130 AMOLED DSI panel found on the Qualcomm SM8550 MTP board. By default the the panel is configured to work with DSI compressed streams, but can work in uncompressed video mode since 1080x2400 in RGB888 fits in the 4 DSI lanes bandwidth. While display compression is preferred for performance and power reasons, let's start with the uncompressed video mode support and add the DSC support later on. Reviewed-by:

The back porch timings were correct, only the sync offset was wrong. Correct timing is now reported for 1080i and 576i, but the h offset is incorrect for 480i for non-obvious reasons. Fixes: fb10dc45 ("drm/vc4: hdmi: Correct HDMI timing registers for interlaced modes") Signed-off-by:

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. The resulting VERTA/VERTB register values have been verified against the reference values set by the Raspberry Pi firmware. Signed-off-by: -

The hardware supports the 332 8bpp and 4:4:4:4 16bpp formats, but the table of supported formats didn't include them. Add them in. In theory they are supported for T-format as well as linear, but without a way to test them just add them as linear for now. Signed-off-by:

atomic_flush will be called for each CRTC even if they aren't enabled. The whole code we have there will thus run without a properly affected channel, which can then result in all sorts of weird behaviour. Reviewed-by:

The bit used for SCALER_DISPBKGND_AUTOHS in SCALER_DISPBKGNDX has been repurposed on HVS5 to configure whether a display can win back-to-back arbitration wins for the COB.

The HVS can change AXI request mode based on how full the COB FIFOs are. Until now the vc4 driver has been relying on the firmware to have set these to sensible values. With HVS channel 2 now being used for live video, change the panic mode for all channels to be explicitly set by the driver, and the same for all channels.

The HVS Composite Output Buffer (COB) is the memory used to generate the output pixel data. Until now the vc4 driver has been relying on the firmware to have set these to sensible values. In testing triple screen support it has been noted that only 1 line was being assigned to HVS channel 2. Whilst that is fine for the transposer (TXP), and indeed needed as only some pixels have an alpha channel, it is insufficient to run a live display. Split the COB more evenly between the 3 HVS channels. Fixes: c54619b0 ("drm/vc4: Add support for the BCM2711 HVS5") Signed-off-by:

Many panel drivers define dsi_dcs_write_seq() and dsi_generic_write_seq() macros to send DCS commands and generic write packets respectively, with the payload specified as a list of parameters instead of using arrays. There's already a macro for the former, introduced by commit 2a9e9daf ("drm/mipi-dsi: Introduce mipi_dsi_dcs_write_seq macro") so drivers can be changed to use that. But there isn't one yet for the latter, let's add it. Signed-off-by:

Replace the combination of bpp and depth with a single color-mode argument. Handle special cases in simpledrm and ofdrm. Hard-code XRGB8888 as fallback format for cases where no given format works. The color-mode argument accepts the same values as the kernel's video parameter. These are mostly bpp values between 1 and 32. The exceptions are 15, which has a color depth of 15 and a bpp value of 16; and 32, which has a color depth of 24 and a bpp value of 32. v4: * add back lost test for bpp_specified (Maira) * add Fixes tag (Daniel) v3: * fix ofdrm build (Maxime) v2: * minimize changes (Daniel) * use drm_driver_legacy_fb_format() (Daniel) Signed-off-by:

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. Signed-off-by:

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. Signed-off-by:

It's a bit a FAQ, and we really can't claim to be the authoritative source for allocating these numbers used in many standard extensions if we tell closed source or vendor stacks in general to go away. Iirc this was already clarified in some vulkan discussions, but I can't find that anywhere anymore. At least not in a public link.

Commit 5ea6b170 ("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.
