* OMAP3: PM: ensure IO wakeups are properly disabledKevin Hilman2010-08-16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit 5a5f561 (convert OMAP3 PRCM macros to the _SHIFT/_MASK suffixes) mistakenly removed the check for PER when disabling the IO chain. During idle, if the PER powerdomain transitions into a lower state and CORE does not, the IO pad wakeups are not being disabled in the idle path after they are enabled. This can happen with the lower C-states when using CPUidle for example. This patch ensures that the check for disabling IO wakeups also checks for PER transitions, matching the check done to enable IO wakeups. Found when debugging PM/CPUidle related problems reported by Ameya Palande <ameya.palande@nokia.com>. Problems were triggered particularily on boards with UART2 consoles (n900, Overo) since UART2 is in the PER powerdomain. Tested on l-o master (omap3_defonfig + CONFIG_CPU_IDLE=y) as well as with current PM branch. Boards tested: n900, Overo, omap3evm.

| | | | | | | | | | | | | | cpu_is_omap3517() and cpu_is_omap3505() are the subgroups of cpu_is_omap34xx(), so we should check cpu_is_omap3517() and cpu_is_omap3505() first, then check cpu_is_omap34xx(). Otherwise, All AM35XX (Sitara) clocks do not get registered and device drivers (ti_hecc, etc...) that depend on those clocks are failing to get the clock and end up with non working device.

This is intended to be used by device drivers (currently, via a struct platform_data function pointer) to retrieve their corresponding device's virtual base address that the MPU should use to access the device. This is needed because the omap_hwmod code does its own ioremap(), in order to gain access to the module's OCP_SYSCONFIG register. Add omap_hwmod_get_mpu_rt_va(). omap_device_get_mpu_rt_va() calls this function to do the real work. While here, rename struct omap_hwmod._rt_va to struct omap_hwmod._mpu_rt_va, to reinforce that it refers to the MPU's register target virtual address base (as opposed to, for example, the L3's). In the future, this belongs as a function in an omap_bus, so it is not necessary to call this through a platform_data function pointer.

This functionality is controlled by adding an extra parameter to omap_hwmod_late_init().

Most users should not need these and usage of theses should be controlled to understand why access is being done in atomic context. For this reason, the non-locking functions are only exposed at the hwmod level and not at the omap-device level. The use-case that led to the need for the non-locking versions is hwmods that are enabled/idled from within the core idle/suspend path. Since interrupts are already disabled here, the mutex-based locking in hwmod can sleep and will cause potential deadlocks.

| | * | | OMAP3: wait on IDLEST after enabling USBTLL fclkAnand Gadiyar2010-07-26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We need to wait on the IDLEST bit after the clocks are enabled before attempting to access any register. Currently, the USBTLL i-clock ops uses the clkops_omap2_dflt_wait, while the USBTLL f-clock ops uses clkops_omap2_dflt. If the i-clock is enabled first, the clkops_omap2_dflt_wait is short-circuited as the companion f-clock is not enabled. This can cause a data abort if the IDLEST has not transitioned, and we try to access a USBTLL register. Since the USBTLL i-clock and f-clock could be enabled in any order, this is a bug. Fix it by changing the clkops for the f-clock. Signed-off-by: Anand Gadiyar <gadiyar@ti.com> Acked-by: Kevin Hilman <khilman@deeprootsystems.com> Signed-off-by: Paul Walmsley <paul@pwsan.com>
