In some platforms there is attached another device to the end of HDMI. The patch adds support for it.
Andrzej, can you clarify what bridge device can be attached and actually is now attached to the end of HDMI? And I wonder if we have the device tree file which defines the bridge device in mainline. Seems we have no the device tree file.
If nothing, then this patch should be merged with real use case.
SiI8620 MHL bridge in tm2/tm2e.
Did you post dt patch to add the properties related to SiI8620 MHL bridge device?
I see below patch series, [PATCH 00/24] drm/bridge/sii8620: add Ultra HD modes support
but I couldn't find dt patch for it. And specifying SiI8620 MHL bridge device as description would be needed.
Thanks.
Patch adding HDMI path to tm2(e) including SiI8620 node and OF bindings between hdmi and SiI8620 [1]. As the bridge framework in lower modes was used only to eliminate unsupported modes, support for bridge in exynos_hdmi driver was not critical, HDMI path worked well and I forgot about it. But for UltraHD modes it is required as SiI8620 uses bridge framework to gather info about applied video mode to program registers accordingly. I will add requested description to this patch.
