Subject: [PATCH 1/2] cpufreq: qcom-nvmem: Enable cpufreq for ipq53xx
|
|
|
|
IPQ53xx have different OPPs available for the CPU based on
|
|
SoC variant. This can be determined through use of an eFuse
|
|
register present in the silicon.
|
|
|
|
Added support for ipq53xx on nvmem driver which helps to
|
|
determine OPPs at runtime based on the eFuse register which
|
|
has the CPU frequency limits. opp-supported-hw dt binding
|
|
can be used to indicate the available OPPs for each limit.
|
|
|
|
nvmem driver also creates the "cpufreq-dt" platform_device after
|
|
passing the version matching data to the OPP framework so that the
|
|
cpufreq-dt handles the actual cpufreq implementation.
