- Fixed commit [5/8]
Changes in v3:
- Disallowed mt8192 compatible in isolation
- Added maxItems to clocks
Changes in v2:
- Rebased over next-20240409 (because of merge issue for patch 1)
- Added ufs: prefix to patch 1
- Added forgotten ufs-rx-symbol clock to the binding
This series performs some fixes and cleanups for the MediaTek UFSHCI
controller driver.
In particular, while adding the MT8195 compatible to the mediatek,ufs
binding, I noticed that it was allowing just one clock, completely
ignoring the optional ones, including the crypt-xxx clocks, all of
the optional regulators, and other properties.
Between all the other properties, two are completely useless, as they
are there just to activate features that, on SoCs that don't support
these, won't anyway be activated because of missing clocks or missing
regulators, or missing other properties;
as for the other vendor-specific properties, like ufs-disable-ah8,
ufs-broken-vcc, ufs-pmc-via-fastauto, since the current merge window
is closing, I didn't do extensive research so I've left them in place
but didn't add them to the devicetree binding yet.
The plan is to check those later and eventually give them a removal
treatment, or add them to the bindings in a part two series.
For now, at least, this is already a big improvement.
P.S.: The only SoC having UFSHCI upstream is MT8183, which only has
just one clock, and *nothing else* uses properties, clocks, etc that
were renamed in this cleanup.
Cheers!
