The LVDS controller can invert the polarity / lanes of the LVDS output. The default polarity causes some issues on some panels. However, U-Boot has always used the opposite polarity without any reported issue, and the only currently supported LVDS panel in-tree (the TBS A711) seems to be able to work with both settings. Let's just use the same polarity than U-Boot to be more consistent and hopefully support all the panels. Signed-off-by:

Print an error message inside ps8640_bridge_vdo_control() function when it fails so we can simplify a bit the callers, they will only need to check the error code. Reviewed-by:

Bridge drivers that implement the new model only shall return an error from their attach() handler when the DRM_BRIDGE_ATTACH_NO_CONNECTOR flag is not set. So make sure we return an error because only the new drm_bridge model is supported. Reviewed-by:

In an eDP application, HPD is not required and on most bridge chips useless. If HPD is not used, we need to set initial status as connected, otherwise the connector created by the drm_bridge_connector API remains in an unknown state. Reviewed-by:

This patch implements WA for AM65xx erratum i2000, which causes YUV formats to show wrong colors. An earlier patch removed a partial WA: a8d9d7da ("drm/tidss: remove AM65x PG1 YUV erratum code") The patch explains the reasoning for removal. The change in plans has been that it has become clear that there are and will be users for PG1 SoCs and as such it's good to implement the WA for PG1s. This patch adds the WA back so that it is only used on SR1.0 (which is the new name for PG1). The previous WA code didn't check the SoC revision, which this patch does. Signed-off-by:

Finalize he conversion of GMA500 to use only GPIO descriptors. The GPIO look-up-table is associated with the device directly in the GMA500 Medfield chip driver since no explicit platform type device (such as in x86/platform/intel-mid) exists: the GMA500 probes directly from the PCI device. Apparently GPIOs 128 and 34 are used on all of these so just go ahead and register those for resetting the DSI pipes. Acked-by:
