Subject: dt-bindings: sram: Document qcom,rpm-msg-ram
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=d0fe6491ddd2232e53d7fd8ee56e37d2c0a511be;p=linux.git

dt-bindings: sram: Document qcom,rpm-msg-ram

The Qualcomm SMEM binding always depended on a reference to a SRAM node
of compatible "qcom,rpm-msg-ram", document this as part of the SRAM
binding.

The SRAM is consumed as a whole and not split up using subnodes, so
properties related to this are not required.
