2024-08-15drm/rockchip: dw_hdmi: Fix reading EDID when using a forced modeJonas Karlman1-0/+2
EDID cannot be read on RK3328 until after read_hpd has been called and correct io voltage has been configured based on connection status. When a forced mode is used, e.g. video=1920x1080@60e, the connector detect ops, that in turn normally calls the read_hpd, never gets called. This result in reading EDID to fail in connector get_modes ops. Call dw_hdmi_rk3328_read_hpd at end of dw_hdmi_rk3328_setup_hpd to correct io voltage and allow reading EDID after setup_hpd.

2024-08-15drm/rockchip: dw_hdmi: Drop superfluous assignments of mpll_cfg, cur_ctr and ↵Cristian Ciocaltea1-6/+0
phy_config The mpll_cfg, cur_ctr and phy_config members in struct dw_hdmi_plat_data are only used to configure the Synopsys PHYs supported internally by DW HDMI transmitter driver (gpu/drm/bridge/synopsys/dw-hdmi.c), via hdmi_phy_configure_dwc_hdmi_3d_tx(), which is further invoked from dw_hdmi_phy_init(). This is part of the internal dw_hdmi_synopsys_phy_ops struct, managed within dw_hdmi_detect_phy(). To handle vendor PHYs, DW HDMI driver doesn't make use of the internal PHY ops and, instead, relies on the glue layer to provide the phy_ops and phy_name members of struct dw_hdmi_plat_data. Drop the unnecessary assignments of DW internal PHY related members from structs rk3228_hdmi_drv_data and rk3328_hdmi_drv_data, since both set the phy_force_vendor flag and correctly provide the expected vendor PHY data.

2024-08-15drm/rockchip: vop: clear DMA stop bit on RK3066Val Packett3-0/+6
The RK3066 VOP sets a dma_stop bit when it's done scanning out a frame and needs the driver to acknowledge that by clearing the bit. Unless we clear it "between" frames, the RGB output only shows noise instead of the picture. atomic_flush is the place for it that least affects other code (doing it on vblank would require converting all other usages of the reg_lock to spin_(un)lock_irq, which would affect performance for everyone). This seems to be a redundant synchronization mechanism that was removed in later iterations of the VOP hardware block.

2024-08-12drm/panic: Add panic descriptionJocelyn Falempe1-13/+45
Now that kmsg dump callback has the description parameter, use it in the user panic screen. This is the string passed to panic(), like "VFS: Unable to mount root fs on xxx" or "Attempted to kill init! exitcode=0xxxx". It gives a hint on why the panic occurred, without being too cryptic.

2024-08-09drm/mgag200: Remove BMC outputThomas Zimmermann9-140/+0
Mgag200's BMC connector tracks the status of an underlying physical connector and updates the BMC status accordingly. This functionality works around GNOME's settings app, which cannot handle multiple outputs on the same CRTC. The workaround is now obsolete as the VGA-BMC connector handles BMC support internally. Hence, remove the driver's code and the BMC output entirely.

2024-08-09drm/mgag200: vga-bmc: Control BMC scanout from encoderThomas Zimmermann5-15/+20
Move calls to stop and start BMC scanout from CRTC helpers to the VGA-BMC encoder's atomic_disable and atomic_enable. Makes the BMC scanout transparent to the CRTC. DRM's atomic helpers call an encoder's atomic_disable and atomic_enable helpers for all enabled encoders. The BMC stops scanning out the VGA signal if modeset disables the VGA encoder, and starts scanning out if the modeset enables the VGA encoder.

2024-08-09drm/mgag200: vga-bmc: Control CRTC VIDRST flag from encoderThomas Zimmermann2-3/+18
Control the VIDRST pin from the VGA-BMC encoder's atomic_check and remove the respective code from CRTC. Makes the VIDRST functionality fully composable. The VIDRST pin allows an external clock source to control the SYNC signals of the Matrox chip. The functionality is part of the CRTC, but depends on the presence of the clock source. This is the case for some BMCs, so control the pin from the VGA-BMC output.

2024-08-09drm/mgag200: vga-bmc: Transparently handle BMCThomas Zimmermann1-2/+48
The VGA-BMC connector selects the VGA output if a display has been attached to the physical connector. Otherwise it selects the BMC output. In any case, the connector status is set to 'detected', so that the userspace compositor displays to it. Depending on the setting, the connector's display modes either come from the VGA monitor's EDID or from an internal list of BMC-compatible modes.
