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/sdm845-shift-axolotl.dtb: hwlock: 'reg' is a required property qcom/sdm845-shift-axolotl.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/sdm845.dtsi | 11 +++-------- 1 file changed, 3 insertions(+), 8 deletions(-) diff --git a/arch/arm64/boot/dts/qcom/sdm845.dtsi b/arch/arm64/boot/dts/qcom/sdm845.dtsi index 21ed14200986..bd0ec0664283 100644 --- a/arch/arm64/boot/dts/qcom/sdm845.dtsi +++ b/arch/arm64/boot/dts/qcom/sdm845.dtsi @@ -919,12 +919,6 @@ compute-cb@8 { }; }; - tcsr_mutex: hwlock { - compatible = "qcom,tcsr-mutex"; - syscon = <&tcsr_mutex_regs 0 0x1000>; - #hwlock-cells = <1>; - }; - smp2p-cdsp { compatible = "qcom,smp2p"; qcom,smem = <94>, <432>; @@ -2588,9 +2582,10 @@ ipa: ipa@1e40000 { status = "disabled"; }; - tcsr_mutex_regs: syscon@1f40000 { - compatible = "syscon"; + tcsr_mutex: hwlock@1f40000 { + compatible = "qcom,tcsr-mutex"; reg = <0 0x01f40000 0 0x20000>; + #hwlock-cells = <1>; }; tcsr_regs_1: sycon@1f60000 { -- 2.34.1
