Subject: arm64: tegra: Mark MAX77620 as system power controller on Smaug
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=00b5b4e5d3c235950a80a7c5ca9297233640cbe9;p=thirdparty%2Fkernel%2Flinux.git

arm64: tegra: Mark MAX77620 as system power controller on Smaug

Register the MAX77620 PMIC as the system power controller on Pixel C so
the driver can install its sys-off handler.

This allows the PMIC poweroff sequence to override the non-working PSCI
SYSTEM_OFF implementation on this platform.
