the reason is that the local timer will stop when enter C3 state,
we need switch the local timer to bc timer when enter the state
and switch back when exit from the that state.The code is like this:

clockevents_notify(CLOCK_EVT_NOTIFY_BROADCAST_EXIT, &cpu);

the ARM, and ARM has no chance to handle it since local irq is disabled.
In fact it's disabled in cpu_idle() of arch/arm/kernel/process.c)

the broadcast timer interrupt will wake up the CPU and run:

}

        delta = ktime_to_ns(ktime_sub(expires, now));

        if (delta <= 0)
                return -ETIME;
when the bc timer interrupt arrives,  which means the last local timer
expires too. so, clockevents_program_event will return -ETIME, which will
cause the dev->retries++ when retry to program the expired timer.

Even under the worst case, after the re-program the expired timer,
then CPU enter idle quickly before the re-progam timer expired,
it will make system ping-pang forever if no interrupt happen.

ENGR00240740-1 IPUv3:Workaround bootup ipu error

Enabling IPU hsp clock in mxcfb_probe() context by calling
ipu_init_channel() can avoid the IPU display channel(setup
in bootloader) from being damaged by some IPU common driver
APIS which enable/disable IPU hsp clock when doing driver
probe. However, somehow, after LDO bypass patch set is pushed
to kernel, this clock enablement can trigger IPU errors
(IPU_INT_STAT_5 - 0x00800000/IPU_INT_STAT_10 - 0x00100000) and
a display flash. A workaround is to enable IPU hsp clock when
we are at ipu_probe() context, which is earlier than mxcfb_probe()
context, and then to disable(cleanup) the clock once more when
fb_set_par() is triggered by the user for the first time. This
patch exports an interface to disable ipu hsp clock so that
fb_set_par() may call it, and enables ipu hsp clock in ipu_probe()
context.

(with DVP Interface) R2.14.pdf,
change back from QSXGA to VGA, don't need to do exposure calculation.

According to the test result, if we do exposure calculation when change
back from scaling to subsampling mode, the image would be dark.

So the method is:
Change to scaling mode, go through exposure calcuation.
Change to or back to subsampling mode, change mode directly.

Supported mode:
- QSXGA@7.5fps
- 1080P@7.5fps

Can't make 1080P works at 15fps. Here is a reply from ov fae:
because of scaling down, max frame for 1080P is the same as 5M, both are 15fps.

Flickering issue happens when there's no buffer to be processed(e.g., the

refining the output of the working_q buffer list, that is, if there's no buffer
to be processed then output to a dummy buffer.

Another important change is to only do DMA reflash operation when SOF is
detected in streamon. Remove this operation is CSI interrupt handler because
it violates to the SPEC (only do DMA reflash before DMA is enabled but NOT at

In this patch, add delay before reading ASRC FIFO status to prevent
noise.
