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/sc7180-trogdor-wormdingler-rev1-inx.dtb: hwlock: 'reg' is a required property qcom/sc7180-trogdor-wormdingler-rev1-inx.dtb: hwlock: 'syscon' does not match any of the regexes: 'pinctrl-[0-9]+' Signed-off-by: Krzysztof Kozlowski <krzysztof.kozlowski@linaro.org> --- arch/arm64/boot/dts/qcom/sc7180.dtsi | 11 +++-------- 1 file changed, 3 insertions(+), 8 deletions(-)
