Subject: [PATCH 00/13] mailbox: pcc: Add support for PCCT extended PCC subspaces

Hi,

Though the series is about adding support for PCCT extended PCC subspaces,
except one patch, remaining are either preparatory or clean up to add
the PCCT extended PCC subspaces. Only patch 12 adds the support of extended
PCC type3/4 subspaces.

The main change affecting your is the change in pcc_mbox_request_channel
to avoid clien driver using con_priv member which is designed for controller
private pointer rather than for client's to use that.

Shared memory region accesses could be consolidated but I am planning to
take that up later as some drivers are using different types of mappings,
yet to figure out on how to consolidate that aspect.

Regards,
Sudeep
