This patch series is remaining part of dma hwmod to support pm runtime and for handling mstandby mode for all applicable DMA mstandby mode errata. The alignment for pm runtime API's usage is at: http://thread.gmane.org/gmane.linux.ports.arm.omap/51588/focus=52493 http://thread.gmane.org/gmane.linux.ports.arm.omap/50762/focus=50840 The alignment for handling mstandby mode errata handling is at: http://thread.gmane.org/gmane.linux.ports.arm.omap/47398/focus=47426 http://thread.gmane.org/gmane.linux.ports.arm.omap/47479/focus=47537 Testing: Compile tested for - omap1_defconfig - omap2plus_defconfig Boot test on: - OMAP1710-H3 - OMAP2420-H4 - OMAP3430-LDP - OMAP3630-Zoom3 - OMAP4430-Blaze DMA memory to memory test cases(including chaining) are executed for all the above boards and for each test case, /sys/devices/platform/omap/omap_dma_system.0/power/runtime_status was verified and after completion of the tests, runtime_status will be always suspended. Apart from that, offmode testing is done for OMAP3430-LDP using the procedure: echo 1 > /debug/pm_debug/sleep_while_idle echo 1 > /debug/pm_debug/enable_off_mode echo 5 > /sys/devices/platform/omap/omap_uart.0/sleep_timeout echo 5 > /sys/devices/platform/omap/omap_uart.1/sleep_timeout echo 5 > /sys/devices/platform/omap/omap_uart.2/sleep_timeout With the above steps, core off mode count gets increasing if the the board is idle for more than 5 seconds.
