Subject: [PATCH] cpufreq: qcom-nvmem: add support for IPQ8074
|
||
|
|
|
||
|
|
IPQ8074 comes in 2 families:
|
||
|
|
* IPQ8070A/IPQ8071A (Acorn) up to 1.4GHz
|
||
|
|
* IPQ8072A/IPQ8074A/IPQ8076A/IPQ8078A (Hawkeye) up to 2.2GHz
|
||
|
|
|
||
|
|
So, in order to be able to share one OPP table lets add support for IPQ8074
|
||
|
|
family based of SMEM SoC ID-s as speedbin fuse is always 0 on IPQ8074.
|
||
|
|
|
||
|
|
IPQ8074 compatible is blacklisted from DT platdev as the cpufreq device
|
||
|
|
will get created by NVMEM CPUFreq driver.
|
||
