2017-06-06[media] v4l: flash led class: Use fwnode_handle instead of device_node in initSakari Ailus4-13/+15
Pass the more generic fwnode_handle to the init function than the device_node.

2017-06-06[media] v4l: async: Add fwnode match supportSakari Ailus3-0/+23
Add fwnode matching to complement OF node matching. And fwnode may also be an OF node. Do not enable fwnode matching yet. It will replace OF matching soon.

2017-06-06[media] v4l: fwnode: Support generic fwnode for parsing standardised propertiesSakari Ailus4-0/+453
The fwnode_handle is a more generic way than OF device_node to describe firmware nodes. Instead of the OF API, use more generic fwnode API to obtain the same information. As the V4L2 fwnode support will be required by a small minority of e.g. ACPI based systems (the same might actually go for OF), make this a module instead of embedding it in the videodev module. The origins of the V4L2 fwnode framework is in the V4L2 OF framework.

2017-06-06[media] au8522: Set the initial modulationDevin Heitmueller1-0/+1
We need to set the initial modulation on driver setup, or else any calls to GET_FRONTEND prior to the first SET_FRONTEND call will get back garbage.

2017-06-06[media] xc5000: Don't spin waiting for analog lockDevin Heitmueller1-24/+2
The xc5000 driver should not be spinning waiting for an analog lock. The ioctl() should be returning immediately and the application is responsible for polling for lock status. This behavior isn't very visible in cases where you tune to a valid channel, since lock is usually achieved much faster than 400ms. However it is highly visible where doing things like changing video standards, which sends tuning request for a frequency that is almost never going to have an actual channel on it. Also fixup the return values to treat zero as success and an actual error code on error (to be consistent with other functions). Note this change has no practical effect at this time as none of the callers inspect the return value.
