Well if a user wants to capture multiple cameras and synchronise,
wouldn't that need sync of i2c and gpio. I understand it may not be
supported but the question is would it be a nice feature for v4l, if so
how to go about it?
Thanks

it's possible to drive I2C clients and
GPIOs with hardware controlled timing to allow for sync control of
sensors hooked and also for fancy strobe. How would we represent these
gpios in v4l2 and allow the control, any ideas on that.
Thanks

Shouldn't this be CONFIG_DMA_ENGINE as you are preparing these descriptors
for DMA transfer?

eters, knowing the hw and reason for this (firmware
download to DSP memory), this doesn't qualify for slave case.
In fact filter function doesn't need a channel, any channel in this
controller will be good

code in case of failure and will pass the -EPROBE_DEFER to the caller in
case dma_request_slave_channel_reason() returned with it.
This is okay but am worried about one more warpper, how about fixing
dma_request_slave_channel_compat()

and it is consistent with what other options
are doing.
Adding a || HAS_IOMEM to the TIMB_DMA dependencies silenced the
kconfig warning about unmet direct dependencies but it was wrong:
without MFD_TIMBERDALE, TIMB_DMA is useless as the driver has no
device to bind to.
Applied, thanks

This also brings me question that should we force the driver to use the
dma_set_mask_and_coherent() API or they have below flexiblity too?
