The linux-3.5 PXA PWM driver followed the hardware numbering scheme for the 4 PWMs, while the linux-3.6-rc1 PXA PWM driver has adopted a linear numbering scheme: Address Hardware 3.5 pwm_id 3.6-rc1 pwm_id 0x40b00000 PWM0 0 0 0x40b00010 PWM2 2 1 0x40c00000 PWM1 1 2 0x40c00010 PWM3 3 3 The hx4700 backlight uses PWM1 at 0x40c00000. Consequently the pwm_id must be changed from 1 to 2. This patch fixes the backlight PWM device number and at the same time moves from the legacy PWM API (pwm_id) to the new PWM API (pwm_lookup).

The culprit is a misconfigured gpio line - GPIO18. GPIO18 should be configured as a regular GPIO input but it gets configured as an alternate function GPIO18_RDY. And then later in postsuspend() it gets configured as a regular GPIO18 input line. Fix this by removing the GPIO18_RDY configuration so that GPIO18 only gets configured as a regular gpio input.

This became an issue on OMAP when we converted omap-i2c.c to use threaded IRQs, it turned out that depending on how much time we spent on suspend, the I2C IRQ thread would end up being rescheduled so far in the future that I2C transfers would timeout and, because omap_hsmmc depends on an I2C-connected device to detect if an MMC card is inserted in the slot, our rootfs would just vanish. arch/arm/kernel/sched_clock.c already had an optional implementation (sched_clock_needs_suspend()) which would handle scheduler's requirement properly, what this patch does is simply to make that implementation non-optional. Note that this has the side-effect that printk timings won't reflect the actual time spent on suspend so other methods to measure that will have to be used. This has been tested with beagleboard XM (OMAP3630) and pandaboard rev A3 (OMAP4430). Suspend to RAM is now working after this patch. Thanks to Kevin Hilman for helping out with debugging.

When CONFIG_VFPv3 is set, but the kernel is booted on a pre-VFPv3 core, the code attempts to save and restore the d16-d31 VFP registers. These are only present on non-D16 VFPv3+, so this results in an undefined instruction exception. The code didn't crash before commit 846a136 because the save and restore code was only touching d0-d15, present on all VFP. Fix by implementing a request from Russell King to add a new HWCAP flag that affirmatively indicates the presence of the d16-d31 registers: http://marc.info/?l=linux-arm-kernel&m=135013547905283&w=2 and some feedback from Måns to clarify the name of the HWCAP flag.

IP blocks marked with this flag are left in the INITIALIZED state during kernel init. This is a workaround for a hardware problem. It should be possible to guarantee that at least one clock source will be present and active for any IP block's main functional clock. This ensures that the hwmod code can enable and reset the IP block. Resetting the IP block during kernel init prevents any bogus bootloader, ROM code, or previous OS configuration from affecting the kernel. Hopefully a clock multiplexer can be added on future SoCs. N.B., at some point in the future, it should be possible to query the clock framework for this type of information. Then this flag should no longer be needed.

This source is not guaranteed to be present on the board, and when present, it is controlled by I2C. This would introduce a board dependency to the early hwmod code which it was not designed to handle. Also, neither the driver for this off-chip clock provider nor the I2C code is available early in boot when the hwmod code is attempting to enable and reset IP blocks. This effectively makes it impossible to enable and reset this device during hwmod init. At its core, this patch is a workaround for an OMAP hardware problem. It should be possible to configure the OMAP to provide any IP block's functional clock from an on-chip source. (This is true for almost every IP block on the chip. As far as I know, McPDM is the only exception.) If the kernel cannot reset and configure IP blocks, it cannot guarantee a sane SoC state. Relying on an optional off-chip clock also creates a board dependency which is beyond the scope of the early hwmod code. This patch works around the issue by marking the McPDM hwmod record with the HWMOD_EXT_OPT_MAIN_CLK flag. This prevents the hwmod code from touching the device early during boot.
