This patch remaps it to use additional frequencies, added in T30+ SoC while maintaining backwards compatibility with T20. - drivers: timer: add timer driver for ARMv7 based Tegra devices Add timer support for T20/T30/T114 and T124 based devices. Driver is based on DM, has device tree support and can be used on SPL and early boot stage. - ARM: tegra: include timer as default option Enable TIMER as default option for all Tegra devices and enable TEGRA_TIMER for TEGRA_ARMV7_COMMON. Additionally enable SPL_TIMER if build as SPL part and drop deprecated configs from common header. P. S. I have no arm64 Tegra and according to comment in tegra-common.h Use the Tegra US timer on ARMv7, but the architected timer on ARMv8.
