Hi Ohad, This is an update to the hwspinlock dt support series. The series is rebased onto v3.17-rc3, and addresses the review comments on the previous v5 series. I have also split and left out the RFC patches about the support for reserved locks (will post these as a separate series) and return code convention changes in the hwspinlock core (will not be needed anymore). The support for deferred probing of clients is supported in the new of_hwspin_lock_get_id() function itself. Following are the main changes in v6 w.r.t v5: - [Patch 1] Updated generic hwspinlock bindings after folding back the hwlock-base-id property from v5 Patch 8 [1]. [Patch 1] - [Patch 4] Updated the common OF helpers patch based on review comments on v5. of_hwspin_lock_request_specific() is replaced with of_hwspin_lock_get_id(). of_hwspin_lock_simple_xlate() is made internal, and of_hwspin_lock_get_base_id() is added. - [Patch 5] Updated the OMAP hwspinlock DT support patch to address review comments about hard-coded base-id, it is parsed from DT if present. - Patches 2 and 3 are unchanged from previous version. - Support patches for AM335x and AM437x SoCs (v5 patches 6 and 7) have been dropped as they are merged in separately for 3.17 - RFC patches (v5 patches 9 through 15) adding the concept of reserved locks and return code change convention dropped. I had looked into dropping the patch to maintain the list of registered spinlocks, but had to retain the patch as it was needed to perform the validity of the args-specifier value in of_hwspin_lock_get_id(). The validation logs on all the applicable OMAP SoCs are at: OMAP4 - http://pastebin.ubuntu.com/8329228 OMAP5 - http://pastebin.ubuntu.com/8329301 DRA74x - http://pastebin.ubuntu.com/8329261 AM33xx - http://pastebin.ubuntu.com/8329199 AM43xx - http://pastebin.ubuntu.com/8329273 The above logs are generated with some additional test patches staged here for reference: https://github.com/sumananna/omap-kernel/commits/hwspinlock/test/3.17-rc3-dt-v6 https://github.com/sumananna/omap-kernel/commits/hwspinlock/submit/3.17-rc3-dt-v6 regards Suman [1] https://patchwork.kernel.org/patch/4096741/ --- v5: http://marc.info/?l=linux-omap&m=139890478402807&w=2 - Rebased v4 patches plus additional RFC patches. - Added back the patch to support DT-based hwlock-base-id property, for registration purposes. - RFC patches introducing the concept of reserved locks. - Staged patches for converting return convention to better support deferred probing of client drivers. v4: - The DT bindings are split into separate patches, and updated to add comments about #hwlock-cells - Fixed a registration issue with repeated module installation and removal. - Added a new OF helper to support #hwlock-cells in addition to the previous OF functions. The OMAP adaptation patch is updated to use the default translate function - Updated hwspinlock documentation to adjust for the structure changes and the new api additions. - Added build support for AM335x, AM43xx and DRA7xx http://marc.info/?l=linux-omap&m=138965904015225&w=2 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 http://marc.info/?l=linux-omap&m=138143992932197&w=2 v2: - Added a new common DT binding documentation and OF helpers. - Revised OMAP DT parse support to use the new OF helper (Patch2) - OMAP5 hwspinlock support including the hwmod entry and DT node - Add AM335x support to OMAP hwspinlock driver, including a fix needed in driver given that AM335 spinlock module requires s/w wakeup - AM335 DT node for spinlock, and a hwmod change to enable smart-idle for AM335. - OMAP4 DT node patch is unchanged http://marc.info/?l=linux-omap&m=137944644112727&w=2 v1: - Add DT parse support to OMAP hwspinlock driver - Add OMAP4 DT node and bindings information http://marc.info/?l=linux-omap&m=137823082308009&w=2 --- Suman Anna (5): Documentation: dt: add common bindings for hwspinlock Documentation: dt: add the omap hwspinlock bindings document hwspinlock/core: maintain a list of registered hwspinlock banks hwspinlock/core: add common OF helpers hwspinlock/omap: add support for dt nodes .../devicetree/bindings/hwlock/hwlock.txt | 55 +++++++ .../devicetree/bindings/hwlock/omap-hwspinlock.txt | 24 +++ Documentation/hwspinlock.txt | 28 ++++ MAINTAINERS | 1 - arch/arm/mach-omap2/Makefile | 3 - arch/arm/mach-omap2/hwspinlock.c | 60 ------- drivers/hwspinlock/hwspinlock_core.c | 173 +++++++++++++++++++++ drivers/hwspinlock/hwspinlock_internal.h | 2 + drivers/hwspinlock/omap_hwspinlock.c | 23 ++- include/linux/hwspinlock.h | 15 +- 10 files changed, 312 insertions(+), 72 deletions(-) create mode 100644 Documentation/devicetree/bindings/hwlock/hwlock.txt create mode 100644 Documentation/devicetree/bindings/hwlock/omap-hwspinlock.txt delete mode 100644 arch/arm/mach-omap2/hwspinlock.c -- 2.0.4 -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
