Bindings are supposed to be organized by device class/function. Move bindings for various timers to timer/ binding directory. Cc: Linus Walleij <linus.walleij@linaro.org> Acked-by: Thierry Reding <thierry.reding@gmail.com> Signed-off-by: Rob Herring <robh@kernel.org>

* MSM Timer
|
|
|
|
Properties:
|
|
|
|
- compatible : Should at least contain "qcom,msm-timer". More specific
|
|
properties specify which subsystem the timers are paired with.
|
|
|
|
"qcom,kpss-timer" - krait subsystem
|
|
"qcom,scss-timer" - scorpion subsystem
|
|
|
|
- interrupts : Interrupts for the debug timer, the first general purpose
|
|
timer, and optionally a second general purpose timer, and
|
|
optionally as well, 2 watchdog interrupts, in that order.
|
|
|
|
- reg : Specifies the base address of the timer registers.
|
|
|
|
- clocks: Reference to the parent clocks, one per output clock. The parents
|
|
must appear in the same order as the clock names.
|
|
|
|
- clock-names: The name of the clocks as free-form strings. They should be in
|
|
the same order as the clocks.
|
|
|
|
- clock-frequency : The frequency of the debug timer and the general purpose
|
|
timer(s) in Hz in that order.
|
|
|
|
Optional:
|
|
|
|
- cpu-offset : per-cpu offset used when the timer is accessed without the
|
|
CPU remapping facilities. The offset is
|
|
cpu-offset + (0x10000 * cpu-nr).
|
|
|
|
Example:
|
|
|
|
timer@200a000 {
|
|
compatible = "qcom,scss-timer", "qcom,msm-timer";
|
|
interrupts = <1 1 0x301>,
|
|
<1 2 0x301>,
|
|
<1 3 0x301>,
|
|
<1 4 0x301>,
|
|
<1 5 0x301>;
|
|
reg = <0x0200a000 0x100>;
|
|
clock-frequency = <19200000>,
|
|
<32768>;
|
|
clocks = <&sleep_clk>;
|
|
clock-names = "sleep";
|
|
cpu-offset = <0x40000>;
|
|
};
