Subject: [PATCH] cpufreq: qcom-nvmem: add support for IPQ6018
|
||
|
||
IPQ6018 SoC series comes in multiple SKU-s, and not all of them support
|
||
high frequency OPP points.
|
||
|
||
SoC itself does however have a single bit in QFPROM to indicate the CPU
|
||
speed-bin.
|
||
That bit is used to indicate frequency limit of 1.5GHz, but that alone is
|
||
not enough as IPQ6000 only goes up to 1.2GHz, but SMEM ID can be used to
|
||
limit it further.
|
||
|
||
IPQ6018 compatible is blacklisted from DT platdev as the cpufreq device
|
||
will get created by NVMEM CPUFreq driver.
