From: Orson Zhai <redacted>


Fix a real problem for SPRD's mailbox driver in patch 1/3.
Add supplementary inbox support for newly added sc9863a in patch 3/3 and
change dt bindings yaml accordingly in patch 2/3.

Changes Log:
V3:
- Add Reviewed-by tag from Baolin for driver code.
- Change interrupt-names syntax in dt-bindings according to Rob's comment.

V2:
- Change patches order. (Yaml go to the head of dirver)
- Remove unnecessary initializing refcnt to zero. 
- Add fix of possible crash caused by NULL of chan->cl. (Actually move from
  changes to sprd-mailbox.c of patch v1)
- Remove unnecessary "inline" for do_inbox_isr().
- Fix yaml errors from Rob's robot checking.
- Add sc9863a compatible string for real supplementary inbox usage. (sc9860
  is not supported by supp-inbox)
- Add more details to supp-inbox in commit messages.

Orson Zhai (3):
  mailbox: sprd: Introduce refcnt when clients requests/free channels
  mailbox: sprd: Add supplementary inbox support
  dt-bindings: mailbox: Add interrupt-names to SPRD mailbox
