Subject: [PATCH 00/10] hwspinlock-next
Date: Mon, 12 Sep 2011 19:46:55 +0300 [thread overview]
Message-ID: <1315846025-11453-1-git-send-email-ohad@wizery.com> (raw)
This series includes a new u8500 hwspinlock driver from Mathieu,
a core fix from Juan and several other cleanups/fixes
(some of which were reported by Arnd while reviewing Mathieu's
driver).
Maybe the most notable core change is the move to registering
a bank of hwspinlocks in a single API call, rather than the
existing approach which required drivers to register each
hwspinlock separately.
That also allowed eliminating 3 per-lock struct members
(dev and ops, which are now maintained per-bank, and id, which
is completely removed, and instead, derived from the array index
of the hwspinlock struct).
The result is ~20% code reduction in the hwspinlock drivers and
a smaller memory footprint.
Juan Gutierrez (1):
hwspinlock/core: use a mutex to protect the radix tree
Mathieu J. Poirier (1):
hwspinlock/u8500: add hwspinlock driver
Ohad Ben-Cohen (8):
hwspinlock/core: simplify Kconfig
hwspinlock/core: simplify 'owner' handling
hwspinlock/omap: simplify allocation scheme
hwspinlock/core/omap: fix id issues on multiple hwspinlock devices
hwspinlock/core: remove stubs for register/unregister
hwspinlock/core: register a bank of hwspinlocks in a single API call
hwspinlock/omap: omap_hwspinlock_remove should be __devexit
hwspinlock: add MAINTAINERS entries
