[PATCHv3 0/5] OMAP Mailbox framework adoption & DT support

From: Suman Anna
Date: Tue Jul 29 2014 - 20:35:35 EST


Hi,

This is an updated version of the OMAP Mailbox framework adoption &
DT support series, refreshed to work with the v9 version of the mailbox
framework [1] from Jassi Brar while also addressing some minor review
comments. Detailed changes are summarized below. Patches are based on
3.16-rc2.

The series depends on the OMAP mailbox DT/hwmod cleanup series [2] and the
OMAP mailbox cleanup series [3]. Both these series are staged to be merged
for 3.17 [4]. The last 2 framework adaptation patches require the v9 framework
patches to build successfully. The reference branch with all the patches is
hosted (not for merging - includes an additional patch for dsp/bridge changes) at
https://github.com/sumananna/mailbox/commits/submit/3.16-rc2-omap-mbox-v9-fwk-v3

The AM335 PM suspend series [5] which relies on this series needs to have
the wkupm3 node updated to use the new property name "mboxes" instead of
"mbox", and use the updated mbox_request_channel API.

Changes in v3:
- Revised the OMAP mailbox bindings to reflect the updated compatible
strings (Patch 1) and the updated common mailbox properties in
the v9 framework (Patch 4)
- Code rearrangement/flip of if code blocks in omap_mailbox probe to address
Markus Mayer's comments from v2 (Patch 2)
- omap_mbox_of_xlate updated to add a missing of_node_put (Patch 4)
- Adjust the added OMAP non-DT support API, omap_mbox_request_channel, to
handle the loss of the chan_name field in the mbox_client structure
from v8 to v9 of mailbox framework (Patch 4)
- Dropped mailbox adaptation changes to TI DSP/Bridge driver, as it will be
deleted in 3.17 (Patch 4)
- No changes to DTS patches (Patches 3 and 5)
- Tested against v9 of mailbox framework

v2:
- http://www.spinics.net/lists/linux-omap/msg109379.html
- Updated the OMAP DT bindings document for the added back DT properties:
"ti,mbox-num-users" and "ti,mbox-num-fifos". Also added information
regarding "#mbox-cells" and DT client usage.
- Updated the OMAP DT adaptation patch to parse the added back DT properties
and clean up the previous match data structure.
- Squashed custom xlate patch into the framework adaptation patch.
- Tested against v8 of mailbox framework.

v1:
- http://www.spinics.net/lists/linux-omap/msg108595.html
- Tested against v7 of mailbox framework
