[PATCHv3 2/4] arm: dts: Change dw-apb-timer-osc and dw-apb-timer-sp to just dw-apb-timer

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

 




From: Dinh Nguyen <dinguyen@xxxxxxxxxx>

"dw-apb-timer-osc" and "dw-apb-timer-sp" are the same implementation of the
DW APB timer, just fed by different clocks. Thus, deprecate both
"dw-apb-timer-osc" and "dw-apb-timer-sp" in lieu of "dw-apb-timer".

v3:
- Split out a separate that cleans up the timer entries and clock information.
- Clearly states which binding is deprecated in the bindingd doc.

v2:
- Deprecate the "dw-apb-timer-osc" and "dw-apb-timer-sp" but maintain
  backwards compatibility in the driver.
