2023-08-04drm: bridge: dw_hdmi: Fix ELD is not updated issueSandor Yu
The ELD (EDID-Like Data) is not updated when the HDMI cable is plugged into different HDMI monitors. This is because the EDID is not updated in the HDMI HPD function. As a result, the ELD data remains unchanged and may not reflect the capabilities of the newly connected HDMI sink device. To address this issue, the handle_plugged_change function should move to the bridge_atomic_enable and bridge_atomic_disable functions. Make sure the EDID is properly updated before updating ELD.

2023-08-02drm/i915/guc/slpc: Restore efficient freq earlierVinay Belgaumkar
This should be done before the soft min/max frequencies are restored. When we disable the "Ignore efficient frequency" flag, GuC does not actually bring the requested freq down to RPn. Specifically, this scenario- - ignore efficient freq set to true - reduce min to RPn (from efficient) - suspend - resume (includes GuC load, restore soft min/max, restore efficient freq) - validate min freq has been resored to RPn This will fail if we didn't first restore(disable, in this case) efficient freq flag before setting the soft min frequency. v2: Bring the min freq down to RPn when we disable efficient freq (Rodrigo) Also made the change to set the min softlimit to RPn at init. Otherwise, we were storing RPe there.

2023-08-02drm/tiny: panel-mipi-dbi: Allow sharing the D/C GPIOOtto Pflüger
Displays that are connected to the same SPI bus may share the D/C GPIO. Use GPIOD_FLAGS_BIT_NONEXCLUSIVE to allow access to the same GPIO for multiple panel-mipi-dbi instances. Exclusive access to the GPIO during transfers is ensured by the locking in drm_mipi_dbi.c.

2023-08-02drm/bridge: Add debugfs print for bridge chainsTomi Valkeinen
DRM bridges are not visible to the userspace and it may not be immediately clear if the chain is somehow constructed incorrectly. I have had two separate instances of a bridge driver failing to do a drm_bridge_attach() call, resulting in the bridge connector not being part of the chain. In some situations this doesn't seem to cause issues, but it will if DRM_BRIDGE_ATTACH_NO_CONNECTOR flag is used. Add a debugfs file to print the bridge chains. For me, on this TI AM62 based platform, I get the following output: encoder[39] bridge[0] type: 0, ops: 0x0 bridge[1] type: 0, ops: 0x0, OF: /bus@f0000/i2c@20000000/dsi@e:toshiba,tc358778 bridge[2] type: 0, ops: 0x3, OF: /bus@f0000/i2c@20010000/hdmi@48:lontium,lt8912b bridge[3] type: 11, ops: 0x7, OF: /hdmi-connector:hdmi-connector Tested-by: Alexander Stein <alexander.stein@ew.tq-group.com> Reviewed-by: Laurent Pinchart <laurent.pinchart+renesas@ideasonboard.com> Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ideasonboard.com> Acked-by: Neil Armstrong <neil.armstrong@linaro.org> Signed-off-by: Neil Armstrong <neil.armstrong@linaro.org> Link: https://patchwork.freedesktop.org/patch/msgid/20230802-drm-bridge-chain-debugfs-v4-1-7e3ae3d137c0@ideasonboard.com
