Many of the DSI flags have names opposite to their actual effects,
e.g. MIPI_DSI_MODE_EOT_PACKET means that EoT packets will actually
be disabled. Fix this by including _NO_ in the flag names, e.g.
MIPI_DSI_MODE_NO_EOT_PACKET.

trace_printk should not be used in production code. Since
tracing interrupts is presumably latency sensitive, pr_dbg is
not appropriate, so guard the call with a preprocessor symbol
that can be defined for debugging purpose.

between the
regulators stays within a specific range, so we'd need to port
that as well.

v5:
- Rename "2d" power domain to "core2"
v4:
- Add power-domain-names description
(kept Alyssa's reviewed-by as the
more changes are still required to get devfreq working, and of course
I do not have a userspace driver to test this with.
I believe at least patches 1 & 2 can be merged (2 depends on another
patch series, so maybe we could start with 1 only for now...).
Thanks!

For testing only, the driver doesn't really work yet, AFAICT.

v5:
- Change power domain name from 2d to core2.
v4:
- Add power domain names.
v3:
- Match mt8183-mali instead of bifrost, as we require special
handling for the 2 regulators and 3 power
FG_CORE2 for consistency.
Thanks! I think I'll keep MT8183_POWER_DOMAIN_MFG_2D (that's fine if
that's the domain name you use internally in your HW design), but I'll
modify power-domain-names to core0/1/2 in the binding.

Some GPUs, namely, the bifrost/g72 part on MT8183, have a second
regulator for their SRAM, let's add support for that.
We extend the framework in a generic manner so that we could
support more than 2 regulators, if required.
