Subject: [PATCH 0/2] drm/bridge: dw-hdmi: disable loading of DW-HDMI CEC sub-driver
Date: Fri, 16 Apr 2021 11:27:35 +0200 [thread overview]
Message-ID: <20210416092737.1971876-1-narmstrong@baylibre.com> (raw)
This adds DW-HDMI driver a glue option to disable loading of the CEC sub-driver.
On some SoCs, the CEC functionality is enabled in the IP config bits, but the
CEC bus is non-functional like on Amlogic SoCs, where the CEC config bit is set
but the DW-HDMI CEC signal is not connected to a physical pin, leading to some
confusion when the DW-HDMI CEC controller can't communicate on the bus.
