Also changed the timeout value for IO chain enable to 100us and added a wait for status disable at the end. Thanks to Nishanth Menon <nm@ti.com> for contributing a fix to the timeout code waiting for WUCLKOUT to go high.

The below steps are followed to enable/ disable the IO chain, based loosely on the "Sec 3.5.7.2.2 I/O Wake-Up Mechanism" section in OMAP3630 Public TRM[1]. Steps to enable IO chain: [a] Set PM_WKEN_WKUP.EN_IO bit [b] Set the PM_WKEN_WKUP.EN_IO_CHAIN bit [c] Poll for PM_WKST_WKUP.ST_IO_CHAIN. [d] When ST_IO_CHAIN bit set to 1, clear PM_WKEN_WKUP.EN_IO_CHAIN [e] Clear ST_IO_CHAIN bit. Steps to disable IO chain: [a] Clear PM_WKEN_WKUP.EN_IO_CHAIN bit [b] Clear PM_WKEN_WKUP.EN_IO bit [c] Clear PM_WKST_WKUP.ST_IO bit by writing 1 to it. Step [e] & [c] in each case can be skipped, as these are handled by the PRCM interrupt handler later.

However, several unrelated omap3 PRM functions have made it inside the #else clause of the #ifdef wrapping the omap2_prm stubs, causing them to disappear on OMAP4-only builds. This was unnoticed until the IO chain support was added and introduced a new function in this section which is referenced by omap_hwmod.c: arch/arm/mach-omap2/omap_hwmod.c: In function '_reconfigure_io_chain': arch/arm/mach-omap2/omap_hwmod.c:1665:3: error: implicit declaration of function 'omap3xxx_prm_reconfigure_io_chain' [-Werror=implicit-function-declaration] Fix by using the #ifdef to only wrap the omap2_prm functions that need stubs on OMAP4-only builds.

The imx5_pm_init call is now exported and called during the MACHINE_START late_init in supported imx5 platforms. Remove various enabling/disabling of the gpc_dvfs clock and enable it once during initialization. This is a very low power clock that must be enabled during low power operations. There are only two "suspend_state_t" imx5 low power modes ever used. STOP_POWER_OFF for suspend to mem and WAIT_UNCLOCKED_POWER_OFF for idle and suspend to standby. The latter mode only requires 500 nanoseconds of extra hardware exit time beyond a basic WFI operation (WAIT_CLOCKED mode) so no other idle mode is necessary. Given this information, it is more efficient to keep the registers in the often used WAIT_UNCLOCKED_POWER_OFF state and only to and from the STOP_POWER_OFF register state as needed when suspend to mem is required.

With this change, IMX_IO_P2V(MX50_AIPS2_BASE_ADDR) == IMX_IO_P2V(MX51_AIPS2_BASE_ADDR) == IMX_IO_P2V(MX53_AIPS2_BASE_ADDR). This change was tested for mapping conflicts using the iop2v script found at git://git.pengutronix.de/git/ukl/imx-iop2v.git and by performing a bootup of a default build using imx_v6_v7_defconfig on a imx51 babbage board and imx53 loco board. The comments were modified to reflect the output given by the script which shows the virtual address mappings.

The SPARSE_IRQ support forces irqs allocation starting from 16. All those static irq number definition for SoCs need to shift 16 to keep non-DT boot works. With all those static IRQ number and start definitions removed from mach/irqs.h, the header becomes just a container of a couple of mach-imx specific irq/fiq calls. Since mach/irqs.h is not included by asm/irq.h now, the users of mxc_set_irq_fiq needs to explicitly include mach/irqs.h themselves.

The imx serial driver has a references to it for a decision on flags of request_irq call based on rtsirq is beyond MXC_INTERNAL_IRQS. However the searching on imx platform code tells that rtsirq will never be beyond MXC_INTERNAL_IRQS. That said, the check, consequently the reference to MXC_INTERNAL_IRQS are not needed, so remove them.
