- 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/T124 and T210 based devices. Driver is based on DM, has device tree support and can be used on SPL and early boot stage.
Arm64 Tegra (apart T210) according to comment in tegra-common.h use architected timer.
- ARM: tegra: include timer as default option Enable TIMER and TEGRA_TIMER for TEGRA_ARMV7_COMMON and TEGRA210. Additionally enable SPL_TIMER if build as SPL part and drop deprecated configs from common header.
--- Changed from v7 - configured timer selection only for armv7 Tegra and T210
Changed from v6 - use clk_m as timer calibration clock (this should properly fix T210) - enable timer for T210
Changed from v5: - added paz00 tester
Changed from v4: - added comments
Changed from v3: - removed BOOTSTAGE ifdefs - use early timer on boot stage unconditionally ---
