Subject: [PATCH v3] arm64: dts: qcom: qdu/qru1000-idp: Fix the voltage setting
While adding the USB support, it was found that the configuration
for regulator smps5 was incorrectly set. Upon cross verifying for
all the regulators, found that smps4, smps6 and smps8 are also
incorrectly configured. The patch corrects these configurations.
In particular -
- smps4 is 1.574V min and 2.04V max
- smps5 is 1.2V min and 1.4V max
- smps6 is 0.382V min and 1.12V max
- smps8 is fixed at 0.752V
Fixes: d1f2cfe2f669 ("arm64: dts: qcom: Add base QDU1000/QRU1000 IDP DTs")
