Subject: [PATCH 3/8] ARM: dts: qcom: ipq8064: add specific dtsi with smb208
|
|
rpm regulators
|
|
|
|
Add specific ipq8064 dtsi with smb208 rpm regulators.
|
|
|
|
Qcom advise to use this configuration but it's not mandatory and OEM
|
|
can decide to implement their own regulators.
|
|
smb208 regulators are used to scale CPU voltage, L2 cache voltage and
|
|
Ubi32 cores.
|
|
|
|
There regulators are controlled by rpm and to correctly works gsbi4-i2c
|
|
require to be NEVER disabled or rpm will reject any regulator change
|
|
request.
