Hi Tony, The DRA7 Timer12 is completely missing from the kernel. This series adds the support for it, so that all the Timers on DRA7 are represented in the kernel. Timer12 is a special Timer, and is not available for kernel on HS devices, very much similar to the equivalent timer on OMAP3.
Patch 1 is a bit debatable, as I am not entirely sure if the clk API used are acceptable outside the drivers/clk folders. It keeps intact the omap_dm_timer_set_source() API though, and allows it to handle the non-configurability of Timer12 parent within that API. The need for this API is questionable, I am not a big fan as the dmtimer code blindly tries to set the source of every requested API to OMAP_TIMER_SRC_32_KHZ, and then the requestors would have to reset the proper parent source again. It also supports configuring only one of 3 parents (which are valid when added originally for the then SoCs), requiring specific clock aliases to work across different SoCs, but the DRA7 SoC does have more than 3 configurable clock parents, and the indexes may not necessarily match for different timers on different SoCs. Patch 1 won't be needed if we can kill the omap_dm_timer_set_source() API. Patches baselined on 4.3-rc3, but should apply just fine on -rc1 as well. regards Suman Suman Anna (4): ARM: OMAP: dmtimer: check for fixed timers during config ARM: OMAP2+: timer: Remove secure timer for DRA7xx devices ARM: dts: DRA7: Add timer12 node ARM: DRA7: hwmod: Add data for GPTimer 12 arch/arm/boot/dts/dra7.dtsi | 10 +++++++++ arch/arm/mach-omap2/omap_hwmod_7xx_data.c | 36 +++++++++++++++++++++++++++++-- arch/arm/mach-omap2/timer.c | 6 +++--- arch/arm/plat-omap/dmtimer.c | 5 +++++ 4 files changed, 52 insertions(+), 5 deletions(-) -- 2.6.0 -- To unsubscribe from this list: send the line "unsubscribe linux-omap" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
