Add Mediatek MT8173 EFUSE Devicetree binding file

Signed-off-by: Andrew-CT Chen <andrew-ct.chen@xxxxxxxxxxxx>

Looks good to me, minor comment below.

Will queue this for v4.5 once v4.4-rc1 is released.

+= Mediatek MTK-EFUSE device tree bindings =
+This binding is intended to represent MTK-EFUSE which is found in most Mediatek SOCs.
+Required properties:
+- compatible: should be "mediatek,mt8173-efuse" or "mediatek,mt8135-efuse"

Can we make the compatible more generic for mediatek socs? Like
"mediatek,efuse" Or are they different in each SOC?

While we can add an additional "mediatek,efuse" compatible we should
always add the most specific compatible first. Otherwise we cannot
differentiate between SoCs later without changing the device tree.
Yes, that’s correct.

AFAIK, Ideally the driver should have more generic compatible string unless there is any SOC specific thing, and DT can still use the order of specific, generic compatible strings. If not we would end up adding compatible strings into the driver for every new SOC.
