The Lontium LT8912 MIPI-DSI to LVDS and HDMI/MHL bridge features a
single-channel MIPI D-PHY receiver front-end configuration with 4 data
lanes per channel operating at 1.5Gbps per data lane and a maximum
input bandwidth of 6Gbps.

Currently the protection #ifdef CONFIG_DEVFREQ_THERMAL cuts the needed
structures devfreq_cooling_ops and devfreq_cooling_device.
The functions which are supposed to provide the empty implementation complain
about unknown structures.
Similar solution is present in include/linux/devfreq.h.

There is still the issue that loud and small on some
EVBs. For mass production consistency, we need to
increase and put more delay in enable DAC steps.
The suggest from vendor, we need to use 50 us instead
of 20 us for the key step 2 and step 4, insert 20 us
in other every steps.
Therefore, the total delay in enable DAC is about:
50 * 2 + 20 * 16 = 420us
It looks okay.

Sometimes the regulator is shared between several devices, if target rate
and target voltage are equal to initial rate and iniital voltage , the
min_uV and max_uV of regulator will be always equal to zero, other devices

If initial rate is greater than opp rate and initial voltage isn't qeual
to opp volatge, the opp voltage may too low for initial rate, so it's
inappropriate to update voltage when initial voltage isn't qeual to
opp volatge.
In order to solve this problem and consider that the regulator is shared
between several devices on some platforms, make the following two changes.
If the driver doesn't support to change frequency, the opp table should
contain an opp whose rate is geater than or equal to initial rate, so that
the voltage is enough for initial rate and the min_uV and max_uV of
regulator aren't equal to zero after update voltage.
If the driver supports to change frequency, let devfreq framework update
rate and voltage.
