Subject: [PATCH v2] arm64: dts: qcom: qdu/qru1000-idp: Fix the voltage setting
Date: Fri, 24 May 2024 13:52:36 +0530

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. This patch fixes the same.

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")
