As both the qos_work and the gpio work tasks are idempotent and rare, this

As tertiary interrupts are handled by handle_twl4030_sih calling
handle_nested_irq, they do not need their own separate irq thread.
So mark them as 'nested_thread' interrupts to avoid the extra thread
creation.

, intuit what must have caused the interrupt.
If we were trying to write, assume it completed.
If we were trying to read and go something other than 0xFF,
assume the read completed.
If we read 0xFF, assume the read timed-out.

A power_supply_changed should only be reported on significant changes
such as transition between charging and not. Incremental changes
such as charge increasing should not be reported - that can easily
be polled for.

I guess it is 4,5,6 when CORE

something like:
bits_per_byte = number of data bits + 1 bit if parity is used + number
of stop bits
+ 1 for the start bit.

If I do (either from the console or via a button press

losing SYNC, and notice that omap_96m_fck was being enabled and disabled in

omap_96m_fck is upstream for dss_96m_fck which provides the tv_dac_clk.
Could it be this clock turning on and off which causes the problem?

I guess I could selective try denying idle on each clock domain until I find
the one that is the problem..

Here's a theory: perhaps the MPU powerdomain is hitting a low-power state
while waiting for an HDQ interrupt. When the MPU powerdomain is in a low
power state, so
the iclk is
being turned off. Timeouts are because the interrupt is disabled or
ignored.
good luck,

My TRM says - in section 12.3.1.3 Power Management
The MPU subsystem INTC belongs to the CORE power domain.
This is:

Is it wrong, are you wrong, or am I confused?
Thanks,

So
neither the MPU nor
- the HDQ keeps working.
(it's a bit smoke-and-mirrors though .. I want fclk to stay on, so let's make
sure iclk doesn't autoidle, because we *know* they have the same source :-)
