[v2] Add HDMI support for Mediatek Genio 510/700/1200-EVK and Radxa NIO-12L boards

[PATCH v2 01/12] dt-bindings: phy: mediatek,hdmi-phy: Fix clock output names for MT8195

Posted by Louis-Alexis Eyraud 1 month, 3 weeks ago

From: AngeloGioacchino Del Regno <angelogioacchino.delregno@collabora.com>

For all of the HDMI PHYs compatible with the one found on MT8195
the output clock has a different datasheet name and specifically
it is called "hdmi_txpll", differently from the older HDMI PHYs
which output block is called "hdmitx_dig_cts".

Replace clock output name string check by max item number one to allow
the new name on all of the HDMI PHY IPs that are perfectly compatible
with MT8195.

[Louis-Alexis Eyraud: split patch, addressed previous feedback from
mailing list, and reworded description]
