2014-09-21[media] adv7604/adv7842: fix il_vbackporch typo and zero the structHans Verkuil1-1/+1
Both adv7604 and adv7842 had the same typo in the code that sets the vertical backporch for the second interlaced field: it was assigned to vbackporch instead of il_vbackporch. In addition, the timings struct wasn't zeroed in the adv7842 driver, leaving several fields to undefined values causing the timing match function to fail.

Update the recommended writes to those mentioned in the Rev 1.5 version of the ADV7611 Register Settings Recommendations document released by Analog Devices. The document does not mention why the recommended settings have been updated, but presumably those are more fine tuned settings that can enhance performance in some cases.

2014-05-25[media] adv7604: Replace *_and_or() functions with *_clr_set()Laurent Pinchart1-43/+43
The *_and_or() functions take an 'and' bitmask to be ANDed with the register value before ORing it with th 'or' bitmask. As the functions are used to mask and set bits selectively, this requires the caller to invert the 'and' bitmask and is thus error prone. Replace those functions with a *_clr_set() variant that takes a mask of bits to be cleared instead of a mask of bits to be kept.

ADV7604_FMT_CHANGE events was debounced in adv7604_isr() to avoid that a receiver with a unstable input signal would block the event handling for other inputs. This solution was prone to errors.
