Hi everyone, Here is a few patches adding support for the High Speed Timers running on the Allwinner SoCs.
These timers are 64 bits timers running at a much higher speed than the timers used for now on these SoCs, since they are no longer wired to the 24MHz oscillator, but to the AHB clock. This HS timers are actually found in all the supported SoCs but the A10. However, the A20 and A31 come with 4 of these high speed timers, while the A10s and A13 only have two, hence why we introduce two different compatibles. The A31 is not using these for now, as its timers are asserted in reset by a reset controller that first need to gain some support in the kernel first, but that's for another patchset.
