Hi, This is an updated series for adding the device tree support to the OMAP hwspinlock driver. The series is based on 3.12-rc1, and includes patches on hwspinlock driver, OMAP hwmod data files and OMAP DTS files. The updated series adds new patches to enable the hwspinlock driver on OMAP5 and AM335x SoCs as well.
Tested this on Panda4, BeagleBone Black and OMAP5 uEVM (with out-of-tree clock patches from Tero). Changes new in 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) 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 [1] https://lkml.org/lkml/2013/8/14/528 [2] http://marc.info/?t=137823090300005&r=1&w=2 Suman Anna (9): hwspinlock/core: add common dt bindings and OF helpers hwspinlock/omap: add support for dt nodes ARM: dts: OMAP4: Add hwspinlock node ARM: OMAP5: hwmod data: Add spinlock data ARM: dts: OMAP5: Add hwspinlock node hwspinlock/omap: support AM33xx hwspinlock/omap: enable module before reading SYSSTATUS register ARM: dts: AM33XX: Add hwspinlock node ARM: AM33xx: hwmod_data: add the sysc configuration for spinlock .../devicetree/bindings/hwlock/hwlock.txt | 26 +++++++++ .../devicetree/bindings/hwlock/omap-hwspinlock.txt | 31 +++++++++++ arch/arm/boot/dts/am33xx.dtsi | 6 +++ arch/arm/boot/dts/omap4.dtsi | 6 +++ arch/arm/boot/dts/omap5.dtsi | 6 +++ arch/arm/mach-omap2/Makefile | 3 -- arch/arm/mach-omap2/hwspinlock.c | 60 --------------------- arch/arm/mach-omap2/omap_hwmod_33xx_data.c | 13 +++++ arch/arm/mach-omap2/omap_hwmod_54xx_data.c | 44 ++++++++++++++++ drivers/hwspinlock/Kconfig | 2 +- drivers/hwspinlock/hwspinlock_core.c | 61 +++++++++++++++++++++- drivers/hwspinlock/omap_hwspinlock.c | 44 ++++++++++++---- include/linux/hwspinlock.h | 11 ++-- 13 files changed, 233 insertions(+), 80 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 -- 1.8.3.3 -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
