On OMAP4, recently a synchronisation bug is discovered by hardware team, which leads to incorrect timer value read from 32K sync timer IP when the IP is comming out of idle. The issue is due to the synchronization methodology used in the SYNCTIMER IP. The value of the counter register in 32kHz domain is synchronized to the OCP domain register only at count up event, and if the OCP clock is switched off, the OCP register gets out of synch until the first count up event after the clock is switched back -at the next falling edge of the 32kHz clock. Further investigation revealed that it applies to gptimer1 and watchdog timer2 as well which may run on 32KHz. This patch fixes the issue for all the applicable modules. The BUG has not made it yet to the OMAP errata list and it is applicable to OMAP1/2/3/4/5. OMAP1/2/3 it is taken care indirectly by autodeps. By enabling static depedency of wakeup clockdomain with MPU, as soon as MPU is woken up from lowpower state(idle) or whenever MPU is active, PRCM forces the OCP clock to be running and allow the counter value to be updated properly in the OCP clock domain. The bug is going to fixed in future OMAP versions.

Since clk_disable_unused is called as lateinitcall, there can be more than a few workqueues executing off secondary CPU(s). The current code does the following: a) checks if clk is unused b) holds lock c) disables clk d) unlocks Between (a) and (b) being executed on CPU0, It is possible to have a driver executing on CPU1 which could do a get_sync->clk_get (and increase the use_count) of the clock which was just about to be disabled by clk_disable_unused. We ensure instead that the entire list traversal is protected by the lock allowing for parent child clock traversal which could be potentially be done by runtime operations to be safe as well.

Fixing it to read from the physical or virtual address depending on the mmu state also does not work, because there is a period between head.S and exynos_map_io where the mmu is on, the uart is mapped and used, but the chipid mapping is not yet present. Fix addruart to use the ARM Main ID cp15 register to determine if the core is Cortex A15 (EXYNOS5) or not (EXYNOS4).

Until now the build was going through successfully, since it is not being used anywhere in kernel. This bug got introduced by the commit 358f0e630d5409ab3837b86db3595560eae773b6 ("OMAP3: hwmod: support to specify the offset position of various SYSCONFIG register bits.")

PCMCIA depends on __io() returning a valid i/o address, and most ARM platforms require IO_SPACE_LIMIT be set to 0xffffffff for PCMCIA. This needs a better fix with a fixed i/o address mapping, but for now we just restore things to the previous behavior. This fixes at91, omap1, pxa and sa11xx. pxa needs io.h if PCI is enabled, but PCMCIA is not. sa11xx already has IO_SPACE_LIMIT set to 0xffffffff, so it doesn't need an io.h.
