3.5 weeks have passed and I got no reviews. Since deadline of timer dm driver implementation is approaching I am re-sending partches.
- ARM: tegra: remap clock_osc_freq for all Tegra family Enum clock_osc_freq was designed to use only with T20. 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 add 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.
