2008-01-28[NET] smc91x: Make smc91x use IRQ resource trigger flagsRussell King17-36/+36
smc91x is shared between many different platforms. Each platform needs to specify the interrupt type, and in some cases the irq type depends on more than just the build configuration - it depends on runtime checks. Rather than throwing this code into the SMC_IRQ_FLAGS definition, provide a way for these flags to be passed via the IRQ resource itself. Note that IRQF_TRIGGER_* constants are intentionally defined to correspond with the IORESOURCE_IRQ_* interrupt type flags, in much the same way that the low bits of PCI iomem resources correspond with the BAR flag bits. Also provide a way to configure smc91x to read the IRQ flags from the resource. Once all platforms have been converted over (signified by all definitions of SMC_IRQ_FLAGS being -1) SMC_IRQ_FLAGS should be removed.

2008-01-26[ARM] pxa: skip registers saving/restoring if entering standby modeeric miao1-15/+18
registers are retained during standby mode, thus it's not necessary to save/restore and checksum Signed-off-by: eric miao <eric.miao@marvell.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2008-01-26[ARM] pxa: fix PXA27x resumeRussell King1-1/+1
When PXA27x wakes up, tick_resume_oneshot() tries to set a timer interrupt to occur immediately. Since PXA27x requires at least MIN_OSCR_DELTA, this causes us to flag an error. tick_program_event() then increments the next event time by min_delta_ns. However, by the time we get back to programming the next event, the OSCR has incremented such that we fail again. We repeatedly retry, but the OSCR is too fast for us - we never catch up, so we never break out of the loop - resulting in us never apparantly resuming. Fix this by doubling min_delta_ns.

2008-01-26[ARM] pxa: Avoid fiddling with CKEN register on suspendRussell King2-8/+0
The PXA manuals indicate that when in standby or sleep modes, clocks to peripherals are shut off by the processor itself. Eg: PXA270 standby: "In standby mode, all clocks are disabled except those for the power manager and the RTC." PXA270 sleep: "In sleep mode, all clocks are disabled to the processor and to all peripherals except the RTC." PXA255 sleep: "In Sleep Mode, all processor and peripheral clocks are disabled, except the RTC." Therefore, it should be safe to leave the clock enable register alone prior to entering low power modes for these SoCs. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2008-01-26[ARM] pxa: Add PXA3 standby code hooked into the IRQ wake schemeRussell King3-0/+389
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>

2008-01-26[ARM] pxa: program MFPs for low power mode when suspendingRussell King1-2/+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>
2008-01-26[ARM] pxa: make MFP configuration processor independenteric miao3-209/+265
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>

So host caps will include MMC_CAP_MMC_HIGHSPEED and MMC_CAP_SD_HIGHSPEED for pxa3[0|1]0.
