From 775edf7856d81fde852968212cd58fc9a3f8cd7d Mon Sep 17 00:00:00 2001 From: Thierry Reding Date: Thu, 17 Sep 2020 12:07:45 +0200 Subject: soc/tegra: fuse: Extract tegra_get_platform() This function extracts the PRE_SI_PLATFORM field from the HIDREV register and can be used to determine which platform the kernel runs on (silicon, simulation, ...). Note that while only Tegra194 and later define this field, it should be safe to call this on prior generations as well since this field should read as 0, indicating silicon.
