0001 MediaTek Timers
0002 ---------------
0003
0004 MediaTek SoCs have different timers on different platforms,
0005 - CPUX (ARM/ARM64 System Timer)
0006 - GPT (General Purpose Timer)
0007 - SYST (System Timer)
0008
0009 The proper timer will be selected automatically by driver.
0010
0011 Required properties:
0012 - compatible should contain:

0039 Examples:
0040
0041 timer@10008000 {
0042 compatible = "mediatek,mt6577-timer";
0043 reg = <0x10008000 0x80>;
