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/ipq6018-cp01-c1.dtb: hwlock: 'reg' is a required property qcom/ipq6018-cp01-c1.dtb: hwlock: 'syscon' does not match any of the regexes: 'pinctrl-[0-9]+' Signed-off-by: Krzysztof Kozlowski <krzysztof.kozlowski@xxxxxxxxxx> --- arch/arm64/boot/dts/qcom/ipq6018.dtsi | 13 ++++--------- 1 file changed, 4 insertions(+), 9 deletions(-) diff --git a/arch/arm64/boot/dts/qcom/ipq6018.dtsi b/arch/arm64/boot/dts/qcom/ipq6018.dtsi index 6b35f03c4862..a7c7ca980a71 100644 --- a/arch/arm64/boot/dts/qcom/ipq6018.dtsi +++ b/arch/arm64/boot/dts/qcom/ipq6018.dtsi @@ -129,12 +129,6 @@ scm { }; }; - tcsr_mutex: hwlock { - compatible = "qcom,tcsr-mutex"; - syscon = <&tcsr_mutex_regs 0 0x80>; - #hwlock-cells = <1>; - }; - pmuv8: pmu { compatible = "arm,cortex-a53-pmu"; interrupts = <GIC_PPI 7 (GIC_CPU_MASK_SIMPLE(4) | @@ -252,9 +246,10 @@ gcc: gcc@1800000 { #reset-cells = <1>; }; - tcsr_mutex_regs: syscon@1905000 { - compatible = "syscon"; - reg = <0x0 0x01905000 0x0 0x8000>; + tcsr_mutex: hwlock@1905000 { + compatible = "qcom,ipq6018-tcsr-mutex", "qcom,tcsr-mutex"; + reg = <0x0 0x01905000 0x0 0x1000>; + #hwlock-cells = <1>; }; tcsr: syscon@1937000 { -- 2.34.1
