For consistency, I'm also changing the same thing for CONFIG_SOC_IMX51. An additional benefit of this approach is reduced code size for kernels that only include support for one of the two SoCs.

This requires manually requesting self refresh (rather than using the automatic mode implemented by the CCM / ESDCTL), followed by reconfiguring the IOMUXC. Of course the code to do this cannot itself run from DDR so the code is copied to and executed from internal memory. In my tests using a custom i.MX53 board with LPDDR2 RAM this reduced the suspend power consumption from 200mW to 60mW.

This causes a hang when cpuidle support is enabled. The reason for that is ARM core clock is shut down unexpectedly by WAIT mode. It happens with the following call stack: cpuidle_register_governor() cpuidle_switch_governor() cpuidle_uninstall_idle_handler() synchronize_sched() wait_rcu_gp() wait_for_completion() When wait_for_completion() is called as above, all cores are idle/WFI. Hence, the reset value of CCM_CLPCR_LPM - WAIT mode, will trigger a hardware shutdown of the ARM core clock. To fix the regression, we need to ensure that CCM_CLPCR_LPM is initialized into RUN mode earlier than cpuidle governor registration, which is a postcore_initcall. This patch creates function imx6_pm_ccm_init() to map CCM block and initialize CCM_CLPCR_LPM into RUN mode, and have the function called from machine .init_irq hook, which should be early enough.

Turns out now we rely on ARCH_OMAP15XX including hardware.h from memory.h, so without ARCH_OMAP15XX we get build failures. As we have legacy drivers still relying on these indirect includes, let's not add more mach includes to the drivers. Those have to be removed anyways for multiplatform support. Let's fix up mach-omap1 to include soc.h where cpu_is_omap checks are done, and common.h for board-*.c files. But let's keep the indirect memory.h include for now to avoid unnecessary churn in the drivers. Signed-off-by: Tony Lindgren <tony@atomide.com>
