Subject: platform/x86: int3472: Add TPS68470 board data for intel nvl
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=cbc6cd55ae5fb6e15bd761f588d7a3057b0c54f8;p=thirdparty%2Fkernel%2Flinux.git

platform/x86: int3472: Add TPS68470 board data for intel nvl

The Intel NVL platform uses IPU8 powered by a TPS68470 PMIC,
requiring board data to configure the GPIOs and regulators for
proper camera sensor operation.
