Add a driver for programming the Tegra SOC HWPM path. SOC HWPM allows performance monitoring of various Tegra IPs. The profiling tests cases are configured through IOCTLs sent by a userspace profiling app. The IOCTLs provide the following features: - IP discovery and reservation - Buffer management - Whitelist query - Register read/write ops Bug 200702306 Bug 3305495 Change-Id: I65003b126e01bd03d856767c55aa2424bcfd11fb Signed-off-by: Adeel Raza <araza@nvidia.com> Reviewed-on: https://git-master.nvidia.com/r/c/linux-t23x/+/2515148 Reviewed-by: mobile promotions <svcmobile_promotions@nvidia.com> GVS: Gerrit_Virtual_Submit Tested-by: mobile promotions <svcmobile_promotions@nvidia.com>
