Subject: [PATCH v3 0/3] mailbox: qcom-ipcc: Add dt-bindings and header
 files for Kaanapali and Glymur Platforms

Add dt-bindings and header files for the Inter-Processor Communication
Controller on Kaanapali and Glymur platforms.

On earlier platforms, Inter Process Communication Controller (IPCC) used
virtual client IDs and performed virtual-to-physical mapping in hardware,
so the IDs defined in dt-bindings/mailbox/qcom-ipcc.h are common across
platforms. Physical client IDs instead of virtual client IDs are used for
qcom new platforms like Kaanapali and Glymur, which will be parsed by the
devicetree and passed to hardware to use Physical client IDs directly,
so header files are defined under dts.
