[v2,0/2] MediaTek SoC ARM/ARM64 System Timer

Message

In an effort to give some love to the apparently forgotten MT6795 SoC,
I am upstreaming more components that are necessary to support platforms
powered by this one apart from a simple boot to serial console.

This series introduces support to start the System Timer for the CPU
cores found in various MediaTek SoCs including, but not limited to the
MT6795 Helio X10 - and will most probably unblock many developers for
the upstreaming of various platforms.

For a broad overview of why/what/when, please look at the description
of patch [2/2] in this series.

Tested on a MT6795 Sony Xperia M5 (codename "Holly") smartphone.

Changes in v2:
 - Added back a lost line in commit 2/2 (sorry, commit didn't get amended...!)
 - Tested again for safety

  dt-bindings: timer: mediatek: Add CPUX System Timer and MT6795
    compatible
  clocksource/drivers/timer-mediatek: Implement CPUXGPT timers
