Thanks applying all three into omap-for-v4.4/fixes.

The original patch where we handled > the ahclkx as fclk worked, because the fclk clock got enabled in the HW w/o > any SW interaction. > All in all, the McASP found in DRA7 needs all clocks to be enabled. > To satisfy this I have introduced a new flag to hwmod, which means that the > listed optional clocks need to be handled alongside with the fclk clock. > > Regards, > Peter > --- > Peter Ujfalusi (3): > ARM: DTS: dra7: Fix McASP3 node regarding to clocks > ARM: OMAP2+: hwmod: Add hwmod flag for HWMOD_OPT_CLKS_NEEDED > ARM: OMAP: DRA7: hwmod: Add data for McASP3 > > arch/arm/boot/dts/dra7.dtsi | 4 +- > arch/arm/mach-omap2/omap_hwmod.c | 66 > +++++++++++++++++-------------- > arch/arm/mach-omap2/omap_hwmod.h | 3 ++ > arch/arm/mach-omap2/omap_hwmod_7xx_data.c | 56 ++++++++++++++++++++++++++ > 4 files changed, 97 insertions(+), 32 deletions(-) > > -- > 2.6.2 > -- 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/
