HACK: omapdss: HDMI hacks for DRA7x
- Vayu evm has a demux which decides whether i2c2 lines go to the hdmi level
shifter(and finally to the panel) or if they are in their normal state(where
i2c2 is connected to many slaves, one of which is a gpio expander to configure
the LS_OE and CT_HPD pins of the level shifter). This demux is controlled by
a mcasp based gpio. There is no mcasp-gpio driver, neither there is a clean
way to represent such a pin in DT. So the bit is toggled as a hack in the
hdmi driver itself.
- On DRA7x, hdmi phy state transition checks are failing even though hdmi phy is
transitioning correctly, ignore the phy transition checks for now.
These need to be cleaned up later.
