2014-02-28[media] au0828: rework GPIO management for HVR-950qDevin Heitmueller1-7/+14
Restructure the way we bring the various GPIOs out of reset. In particular: 1. we only need to setup the GPIOs as outputs once 2. there's no point in writing 0x40 to register 0x00 since that's the EEPROM write protect and already it's configured as an input 3. Separate out the act of enabling the power supply and bringing the tuner and demod out of reset. If you don't then the chip may not be properly enabled (as the power supply is still ramping up when the chip comes out of reset). This can result in probing failures.

2014-02-28[media] m88rs2000: prevent frontend crash on continuous transponder scansMalcolm Priestley1-0/+17
Add m88rs2000_get_tune_settings, min delay of 2000 ms on symbol rate more than 3000000 and delay of 3000ms less than this. Adding min delay prevents crashing the frontend on continuous transponder scans. Other dvb_frontend_tune_settings remain as default. This makes very little time difference to good channel scans, but slows down the set frontend where lock can never be achieved i.e. DVB-S2.

The uvcvideo driver doesn't support changing the format when buffers have been allocated, but there's no reason not to support allocating buffers larger than the minimum size.

devices Isochronous endpoints on devices with speed == USB_SPEED_WIRELESS can have a max packet size ranging from 1-3584 bytes. Add a case to uvc_endpoint_max_bpi to handle USB_SPEED_WIRELESS. Otherwise endpoints for those devices will fall to the default case which masks off any values > 2047.

2014-02-24[media] vivi: queue_setup improvementsHans Verkuil1-16/+8
Drop the vid_limit module option: there is really no need to limit this. No other driver does that. If you try to allocate more buffers then vb2 will automatically reduce the number of buffers anyway. Also add sanity checks if the size in the fmt argument is going to be used and drop the code that checks against *nbuffers == 0: this can never happen (the vb2 framework ensures that) and the code was wrong anyway since *nbuffers should have been set to the minimum number of required buffers which is 1 for this driver. Since vivi is often used as a template driver it is good to have this driver be as compliant as possible. This broken code was for example copied to the s2255 driver (which is being fixed as well).

Rather than keep adding new ioctls to the list in v4l2-compat-ioctl32.c, just check if the ioctl is a non-private V4L2 ioctl and if so, call the conversion code.
