Hi,
This is an updated series addressing the review comments from the
v2 series. The hwmod patches have been dropped from the repost
as per Paul's request, they have already been queued.
Mark,
Any comments on this series? Tony has picked up the OMAP DTS patches for
3.13, and so
the "ti,omap4-hwspinlock" compatible string is showing up as
undocumented in linux-next.
How do you want me to proceed here? I will be separating out the
bindings into separate patches
in the future.
regards
Suman
The series is tested on top of v3.12-rc4 + Benoit's 3.13 DTS branch and
Tero's clock series, along with the queued hwmod patches.
Changes in v3:
- Removed the DT property hwlock-base-id and associated OF helper
- Added changes in core to support requesting a specific hwlock using
phandle + args approach
- Revised both the common and OMAP DT bindings document
- OMAP AM335 support patches are unchanged from v2.
- OMAP DTS patches are unchanged from v2.
v2
- Added a new common DT binding documentation and OF helpers (Patch1),
addressing the review comments from v1 [2]. The MSM support [1] needs
to be reworked on top of this common patch.
- Revised OMAP DT parse support to use the new OF helper (Patch2)
- OMAP5 hwspinlock support including the hwmod entry and DT node (Patches 4, 5)
- Add AM335x support to OMAP hwspinlock driver, including a fix
needed in driver given that AM335 spinlock module requires s/w wakeup
(Patches 6, 7)
- AM335 DT node for spinlock, and a hwmod change to enable smart-idle
for AM335 (Patches 8, 9). The sysc patch is not essential for AM335
spinlock functionality, but is needed for smart-idling the IP when
the module is enabled.
- OMAP4 DT node patch is unchanged (Patch 3)
