Subject: dt-bindings: interconnect: qcom,msm8998-bwmon: Allow 'nonposted-mmio'
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=a234cffd04bc06386b18976de5b691b23bcf68a4;p=thirdparty%2Fkernel%2Fstable.git

dt-bindings: interconnect: qcom,msm8998-bwmon: Allow 'nonposted-mmio'

One of the BWMON instances on SM8750 requires that its MMIO space is
mapped specifically with the nE memory attribute.

Allow the nonposted-mmio property which instructs the OS to do so.
