Subject: [PATCH v4 3/3] ARM: dts: qcom: msm8974: switch TCSR mutex to MMIO
Date:   Tue, 20 Sep 2022 17:04:14 +0200

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]+'
