The TCSR mutex bindings allow device to be described only with address space (so it uses MMIO, not syscon regmap). This seems reasonable as TCSR mutex is actually a dedicated IO address space and it also fixes DT schema checks: qcom-msm8974-sony-xperia-rhine-amami.dtb: tcsr-mutex: 'reg' is a required property qcom-msm8974-sony-xperia-rhine-amami.dtb: tcsr-mutex: 'syscon' does not match any of the regexes: 'pinctrl-[0-9]+' Signed-off-by: Krzysztof Kozlowski <krzysztof.kozlowski@xxxxxxxxxx> --- arch/arm/boot/dts/qcom-msm8974.dtsi | 12 +++--------- 1 file changed, 3 insertions(+), 9 deletions(-) diff --git a/arch/arm/boot/dts/qcom-msm8974.dtsi b/arch/arm/boot/dts/qcom-msm8974.dtsi index 4b602410d72a..5f674aa819ae 100644 --- a/arch/arm/boot/dts/qcom-msm8974.dtsi +++ b/arch/arm/boot/dts/qcom-msm8974.dtsi @@ -1228,9 +1228,10 @@ smd-edge { }; }; - tcsr_mutex_block: syscon@fd484000 { - compatible = "syscon"; + tcsr_mutex: hwlock@fd484000 { + compatible = "qcom,msm8974-tcsr-mutex", "qcom,tcsr-mutex"; reg = <0xfd484000 0x1000>; + #hwlock-cells = <1>; }; tcsr_1: syscon@fd485000 { @@ -1719,13 +1720,6 @@ reboot-mode { }; }; - tcsr_mutex: tcsr-mutex { - compatible = "qcom,tcsr-mutex"; - syscon = <&tcsr_mutex_block 0 0x80>; - - #hwlock-cells = <1>; - }; - thermal-zones { cpu0-thermal { polling-delay-passive = <250>; -- 2.34.1
