[RFT PATCH v3 03/16] arm64: dts: qcom: msm8996: switch TCSR mutex to MMIO

From: Krzysztof Kozlowski
Date: Fri Aug 19 2022 - 04:32:31 EST


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/msm8996-xiaomi-natrium.dtb: hwlock: 'reg' is a required property
qcom/msm8996-xiaomi-natrium.dtb: hwlock: 'syscon' does not match any of the regexes: 'pinctrl-[0-9]+'
