These patches try to improve dw-apb-ictl irqchip driver a bit. The first patch improves the performance a bit -- use the relaxed version
The two dw-apb-ictl's irq_chip_type instances have separate mask registers, so the second patch enables IRQ_GC_MASK_CACHE_PER_TYPE. The last patch adds suspend/resume support to the driver. Tested on Marvell BG2Q-DMP board. Changes in v2: - Add Sebastian's Acks - Update the first commit as Sebastian and Thomas suggested - Add into commit log summary of the discussion why relaxed variants can be used Jisheng Zhang (3): irqchip: dw-apb-ictl: always use use {readl|writel}_relaxed irqchip: dw-apb-ictl: enable IRQ_GC_MASK_CACHE_PER_TYPE irqchip: dw-apb-ictl: add PM support drivers/irqchip/irq-dw-apb-ictl.c | 32 ++++++++++++++++++++++++++------ 1 file changed, 26 insertions(+), 6 deletions(-) -- 2.1.3 -- 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/
