We can move the handling of the DMA synchronisation control out of the prepare functions; this can be pre-calculated when the DMA channel has been allocated, so we don't need to duplicate this in both prepare functions.

Export the DMA register information from the SoC specific data, such that we can access the registers directly in omap-dma.c, mapping the register region ourselves as well. Rather than calculating the DMA channel register in its entirety for each access, we pre-calculate an offset base address for the allocated DMA channel and then just use the appropriate register offset.

Move the clnk_ctrl setup to the preparation functions, saving its value in the omap_desc.

The patch "rtc: verify a critical argument to rtc_update_irq() before using it" introduces validation for rtc_device in the RTC core, so there are no need to check this argument for rtc_update_irq() from the drivers.

NO_IRQ may be defined as '(unsigned int) -1' in some architectures (arm, sh ...), and either may not be defined in some architectures (arm64) which can enable RTC_DRV_S3C.

Using platform_get_irq_byname() to retrieve the IRQ number returns the VIRQ number rather than the local IRQ number for the device. Passing that value then into regmap_irq_get_virq() causes a failure because the function is expecting the local IRQ number (e.g. 0, 1, 2, 3, etc). This patch removes use of regmap_irq_get_virq() to prevent this failure from happening Signed-off-by: NAdam Thomson <Adam.Thomson.Opensource@diasemi.com> Cc: Alessandro Zummo <a.zummo@towertech.it> Cc: Dmitry Torokhov <dmitry.torokhov@gmail.com> Signed-off-by: NAndrew Morton <akpm@linux-foundation.org> Signed-off-by: NLinus Torvalds <torvalds@linux-foundation.org>

Datasheet says: "When the VSRTC voltage drops to the range of 0.9 - 0.8V, the RTCPORB reset signal is generated and the contents of the RTC will be reset. <skip>. To inform the processor that the contents of the RTC are no longer valid due to the reset, a timer reset interrupt function is implemented with the RTCRSTI bit."
