* [ARM] pxa: Add PXA3 standby code hooked into the IRQ wake schemeRussell King2008-01-262-0/+303
| | | | | | | | | | | | | | | | Wakeup sources on PXA3 are enabled at two levels. First, the MFP configuration has to be set to enable which edges a specific pin will trigger a wakeup. The pin also has to be routed to a functional unit. Lastly, the functional unit must be enabled as a wakeup source in the appropriate AD*ER registers (AD2D0ER for standby resume.) This doesn't fit well with the IRQ wake scheme - we currently do a best effort conversion from IRQ numbers to functional unit wake enable bits. For instance, there's several USB client related enable bits but there's no corresponding IRQs to determine which you'd want. Conversely, there's a single enable bit covering several functional units. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

* [ARM] pxa: program MFPs for low power mode when suspendingRussell King2008-01-261-2/+57
| | | | | | | | | | | | Hook the MFP code into the power management code so that the MFPs can be reconfigured when suspending and resuming. However, note the FIXME - low power mode MFP configuration may depend on the system state being entered. Also note that we have to clear any detected edge events prior to entering a low power mode - otherwise we immediately wake up. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
* [ARM] pxa: make MFP configuration processor independenteric miao2008-01-261-15/+82
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There are two reasons for making the MFP configuration to be processor independent, i.e. removing the relationship of configuration bits with actual MFPR register settings: 1. power management sometimes requires the MFP to be configured differently when in run mode or in low power mode 2. for future integration of pxa{25x,27x} GPIO configurations The modifications include: 1. introducing of processor independent MFP configuration bits, as defined in [include/asm-arm/arch-pxa/mfp.h]: bit 0.. 9 - MFP Pin Number (1024 Pins Maximum) bit 10..12 - Alternate Function Selection bit 13..15 - Drive Strength bit 16..18 - Low Power Mode State bit 19..20 - Low Power Mode Edge Detection bit 21..22 - Run Mode Pull State and so on, 2. moving the processor dependent code from mfp.h into mfp-pxa3xx.h 3. cleaning up of the MFPR bit definitions 4. mapping of processor independent MFP configuration into processor specific MFPR register settings is now totally encapsulated within pxa3xx_mfp_config() 5. using of "unsigned long" instead of invented type of "mfp_cfg_t" according to Documentation/CodingStyle Chapter 5, usage of this in platform code will be slowly removed in later patches Signed-off-by: eric miao <eric.miao@marvell.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

* [ARM] pxa: fix one-shot timer modeRussell King2007-11-081-9/+14
| | | | | | | | | | | | | | | | | One-shot timer mode on PXA has various bugs which prevent kernels build with NO_HZ enabled booting. They end up spinning on a permanently asserted timer interrupt because we don't properly clear it down - clearing the OIER bit does not stop the pending interrupt status. Fix this in the set_mode handler as well. Moreover, the code which sets the next expiry point may race with the hardware, and we might not set the match register sufficiently in the future. If we encounter that situation, return -ETIME so the generic time code retries.

* PM: Rename struct pm_ops and related thingsRafael J. Wysocki2007-10-182-3/+3
| | | | | | | | | | | | | | | | The name of 'struct pm_ops' suggests that it is related to the power management in general, but in fact it is only related to suspend.  Moreover, its name should indicate what this structure is used for, so it seems reasonable to change it to 'struct platform_suspend_ops'.  In that case, the name of the global variable of this type used by the PM core and the names of related functions should be changed accordingly.

There are, at least, the following reasons to do that: * 'struct pm_ops' is specifically related to suspend and not to the power management in general. * As long as 'struct pm_ops' is defined in <linux/pm.h>, any modification of it causes the entire kernel to be recompiled, which is unnecessary and annoying. * Some suspend-related features are already defined in <linux/suspend.h>, so it is logical to move the definition of 'struct pm_ops' into there. * 'struct hibernation_ops', being the hibernation-related counterpart of 'struct pm_ops', is defined in <linux/suspend.h> .

* [ARM] pxa: Avoid pxa_gpio_mode() in gpio_direction_{in,out}put()Russell King2007-10-151-0/+38
| | | | | | | | | | | | | | | | | pxa_gpio_mode() is a universal call that fiddles with the GAFR (gpio alternate function register.) GAFR does not exist on PXA3 CPUs, but instead the alternate functions are controlled via the MFP support code. Platforms are expected to configure the MFP according to their needs in their platform support code rather than drivers. We extend this idea to the GAFR, and make the gpio_direction_*() functions purely operate on the GPIO level. This means platform support code is entirely responsible for configuring the GPIOs alternate functions on all PXA CPU types. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
