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 AngeloGioacchino Del Regno (2): dt-bindings: timer: mediatek: Add CPUX System Timer and MT6795 compatible clocksource/drivers/timer-mediatek: Implement CPUXGPT timers .../bindings/timer/mediatek,mtk-timer.txt | 4 + drivers/clocksource/timer-mediatek.c | 119 ++++++++++++++++++ 2 files changed, 123 insertions(+)
