timer unit of Allwinner A64 UNKNOWN1 bug

[Ilya Dikariev]

Hello all,

owned a Pinephone and it turns out, that the genmask(8,0) is not
sufficient to get a workaround in this particular case.

The phone get freezed pretty often, and after some 10-15 minutes
unfreezes. Time jumps too.

Did the test https://github.com/smaeul/timer-tools that resulted in
https://pastebin.com/xbTeksJN


After applying the patch (changing to genmask(7,0)) the test passed. No
errors within hours and no freezes/time jumps.

Could you implement this into a mainline?

Best regards,
Ilya
