Hi Ohad, This is an updated version of the hwspinlock dt support series, rebased onto v3.19-rc3 and mainly addresses the continued discussion on the need to maintain a list of registered spinlock banks [1]. I have removed this patch as per your wish, and as a result the burden of the spinlock validation and deferred probing is pushed onto the hwspinlock clients. Sorry for the delay in refreshing this series, hopefully this can be the last revision. Following are the main changes in v7 w.r.t v6: - Dropped the patch "hwspinlock/core: maintain a list of registered hwspinlock banks" - Updated generic hwspinlock bindings to make hwlock-base-id property mandatory. - Updated the OMAP hwspinlock binding and DT support patches to correct for the mandatory hwlock-base-id property. - Updated the common OF helpers patch to move the of_hwspin_lock_get_base_id() and of_hwspin_lock_get_num_locks() functions into the internal header, these are no longer exported, but available for platform implementations. of_hwspin_lock_get_id() is also simplified now. The validation logs on all the applicable OMAP SoCs are at: OMAP4 - http://slexy.org/view/s21Mh1SqP8 OMAP5 - http://slexy.org/view/s21TYWxoKu DRA74x - http://slexy.org/view/s2dQdghLPr DRA72x - http://slexy.org/view/s2QajhhWYu AM33xx - http://slexy.org/view/s21DvKQOpa AM43xx - http://slexy.org/view/s21L3YB95Q The above logs are generated with some additional test patches staged here for reference, https://github.com/sumananna/omap-kernel/commits/hwspinlock/test/3.19-rc3-dt-v7 The test branch also includes a required patch that adds the hwlock-base-id to all the OMAP hwspinlock DT nodes (will submit that patch separately for Tony to pick it up). Bjorn, I didn't add your Tested-by: or Reviewed-by as I have modified the series a bit. Care to give those once again, thanks. regards Suman [1] https://patchwork.kernel.org/patch/4898041/ --- v6: http://marc.info/?l=linux-omap&m=141055365213895&w=2 - 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. - Updated the OMAP hwspinlock DT support patch to assign base-id from DT if present - RFC patches adding the concept of reserved locks and return code change convention dropped. 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 (4): Documentation: dt: add common bindings for hwspinlock Documentation: dt: add the omap hwspinlock bindings document 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 | 28 ++++++++++ Documentation/hwspinlock.txt | 25 +++++++++ MAINTAINERS | 1 - arch/arm/mach-omap2/Makefile | 3 - arch/arm/mach-omap2/hwspinlock.c | 60 -------------------- drivers/hwspinlock/hwspinlock_core.c | 65 ++++++++++++++++++++++ drivers/hwspinlock/hwspinlock_internal.h | 47 ++++++++++++++++ drivers/hwspinlock/omap_hwspinlock.c | 22 ++++++-- include/linux/hwspinlock.h | 7 +++ 10 files changed, 244 insertions(+), 69 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 -- 2.2.1 -- 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
