(v4) + +It was covering part of the PM block's range, up to the WDT regs. To +support the rest of the PM block's functionality, we need the full +register range plus the AXI Async Bridge regs for PM sequencing. + +This doesn't convert any of the consumers over to the new binding yet, +since we will need to be careful in coordinating our usage of firmware +services that might power domains on and off versus the bcm2835-pm +driver's access of those same domains. + +Signed-off-by: Eric Anholt <eric@anholt.net> +Acked-by: Stefan Wahren <stefan.wahren@i2se.com> +Signed-off-by: Stefan Wahren <stefan.wahren@i2se.com> +(cherry picked from commit 29abc92c1d93e28a8f4d55e6343eec4faf44025a) +--- + arch/arm/boot/dts/bcm283x.dtsi | 13 +++++++++++-- + 1 file changed, 11 insertions(+), 2 deletions(-) + +--- a/arch/arm/boot/dts/bcm283x.dtsi ++++ b/arch/arm/boot/dts/bcm283x.dtsi +@@ -121,8 +121,17 @@ + }; + + watchdog@7e100000 { +- compatible = "brcm,bcm2835-pm-wdt"; +- reg = <0x7e100000 0x28>; ++ compatible = "brcm,bcm2835-pm", "brcm,bcm2835-pm-wdt"; ++ #power-domain-cells = <1>; ++ #reset-cells = <1>; ++ reg = <0x7e100000 0x114>, ++ <0x7e00a000 0x24>; ++ clocks = <&clocks BCM2835_CLOCK_V3D>, ++ <&clocks BCM2835_CLOCK_PERI_IMAGE>, ++ <&clocks BCM2835_CLOCK_H264>, ++ <&clocks BCM2835_CLOCK_ISP>; ++ clock-names = "v3d", "peri_image", "h264", "isp"; ++ system-power-controller; + }; + + clocks: cprman@7e101000 { |
