[4.4-rc][PATCH] ARM: dts: am4372: disable arm twd and global timer's nodes

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Keep ARM TWD and Global timer's nodes disabled by default - if someone
would like to use them then those nodes have to be enabled explicitly
in board file.

The reason for this change is:
- ARM TWD is not always-on timer on am437x and it will stop in low
  CPUIdle states and, therefore, broadcast timer has to configured
  properly if CPU_IDLE=y.
- ARM Global timer is not always-on timer on am437x and it can't be
  used as clocksource device if CPU_IDLE=y.
- ARM Global timer driver doesn't support CPUfreq now.
