[PATCH 0/2] arm64: dts: qcom: milos: Add QFPROM efuse support

[Alexander Koskovich]

Add dt-bindings and dt-node for Milos QFPROM efuse. The GPU speed bin child
node nvmem cell contains details of clk frequencies supported by the GPU,
which can then read by the GPU driver to select the correct set of operating
performance points (OPPs) for the device in the future once all the possible
speedbins for Milos are known.

[PATCH 2/2] arm64: dts: qcom: milos: Add qfprom efuse node

[Alexander Koskovich]

Add the qfprom efuse node and describe where the GPU speedbin fuse is
located on Milos.

Note that for SM7635-AB at least, the value is "221", the max frequency
for this is 1050MHz. There's another speedbin out there for 1150MHz but
we do not know the value for it so just document in this commit.

Once the value is discovered we should add the speedbins to the A810
Adreno entry and update devicetree.
