[PATCH v3 13/15] ARM: dts: qcom: msm8974: switch TCSR mutex to MMIO

From: Krzysztof Kozlowski
Date: Fri Sep 09 2022 - 05:21:59 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-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]+'
