[PATCH 0/4] Add SCM and mailbox support on MSM8953

This patch series adds support for SCM and mailbox as found on the QCom
MSM8953 platform.
Since all SoCs based on the MSM8953 platform have the same scm and
mailbox configuration, a single compatible string is used.

Vladimir Lypak (4):
  dt-bindings: mailbox: Add compatible for the MSM8953
  mailbox: qcom-apcs-ipc: Add compatible for MSM8953 SoC
  dt-bindings: firmware: qcom-scm: Document msm8953 bindings
  firmware: qcom_scm: Add compatible for MSM8953 SoC

From: Vladimir Lypak <redacted>

MSM8953 has an APCS block similar to MSM8916 but with different clocks
which are spread over 2MB IO region next to it.
