[PATCH] ARM: dts: augment Moxa and Aspeed DTS for FTTMR010

Linus Walleij linus.walleij at linaro.org
Wed May 24 02:07:48 PDT 2017


This augments the Moxa Art and Aspeed device trees to:

- Explicitly name the clock "PCLK" as the Faraday FTTMR010
  names it.
- List the Moxa timer as compatible with the Faradat FTTMR010
  vanilla version.
- Add a comment that the Aspeed driver is a Faraday
  FTTMR010 derivative.
- Pass all IRQs to the timer from Aspeed: they are all there
  so they should be in the device tree, we only use the
  first one anyways.

ARM SoC maintainers: this is the DTS changes needt to generalize
the Faraday timer. Please merge this into some suitable ARM SoC
DTS branch.
Clocksource maintainers: I will ask the ARM SoC people to merge
this patch orthogonally, it is only included in this series
for reference and for testing.
