The r8a7778 is very similar to the r8a7779, and already handled by the current driver in the non-DT case. Signed-off-by: Geert Uytterhoeven <geert+renesas@glider.be> Acked-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Signed-off-by: Simon Horman <horms+renesas@verge.net.au>

* Renesas R-Mobile/R-Car Timer Unit (TMU)
|
|
|
|
The TMU is a 32-bit timer/counter with configurable clock inputs and
|
|
programmable compare match.
|
|
|
|
Channels share hardware resources but their counter and compare match value
|
|
are independent. The TMU hardware supports up to three channels.
|
|
|
|
Required Properties:
|
|
|
|
- compatible: must contain one or more of the following:
|
|
- "renesas,tmu-r8a7740" for the r8a7740 TMU
|
|
- "renesas,tmu-r8a7778" for the r8a7778 TMU
|
|
- "renesas,tmu-r8a7779" for the r8a7779 TMU
|
|
- "renesas,tmu" for any TMU.
|
|
This is a fallback for the above renesas,tmu-* entries
|
|
|
|
- reg: base address and length of the registers block for the timer module.
|
|
|
|
- interrupts: interrupt-specifier for the timer, one per channel.
|
|
|
|
- clocks: a list of phandle + clock-specifier pairs, one for each entry
|
|
in clock-names.
|
|
- clock-names: must contain "fck" for the functional clock.
|
|
|
|
Optional Properties:
|
|
|
|
- #renesas,channels: number of channels implemented by the timer, must be 2
|
|
or 3 (if not specified the value defaults to 3).
|
|
|
|
|
|
Example: R8A7779 (R-Car H1) TMU0 node
|
|
|
|
tmu0: timer@ffd80000 {
|
|
compatible = "renesas,tmu-r8a7779", "renesas,tmu";
|
|
reg = <0xffd80000 0x30>;
|
|
interrupts = <0 32 IRQ_TYPE_LEVEL_HIGH>,
|
|
<0 33 IRQ_TYPE_LEVEL_HIGH>,
|
|
<0 34 IRQ_TYPE_LEVEL_HIGH>;
|
|
clocks = <&mstp0_clks R8A7779_CLK_TMU0>;
|
|
clock-names = "fck";
|
|
|
|
#renesas,channels = <3>;
|
|
};
