Re: [Patch v1 2/3] arm64: tegra: add node for tegra234 cpufreq

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 





Adding cclpex node to represent Tegra234 cpufreq.
Tegra234 uses some of the CRAB (Control Register Access Bus)
registers for cpu frequency requests. These registers are
memory mapped to CCPLEX_MMCRAB_ARM region. In this node, mapping
the range of MMCRAB registers required only for cpu frequency info.

We need to add this compatible string to a DT binding doc somewhere.
It seems the binding doc was previously posted in [1] for T186 SoC.
Same will be applicable for T234 SoC also. Only compatible string need to be added. Should I sent a separate patch after converting it to yaml format and add compatible string (or) send as part of v2.
