[PATCH v4 0/3] Timer support for ARM Tegra

[Svyatoslav Ryhel]

- 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.
