42752f7a3f V4L/DVB (13176): adv7180: Support checking standard via interrupts
If the I2C device provides an interrupt it is registered and the
standard
is updated via interrupts rather than polling.

Since I2C communication is needed, the interrupt handler fires off a
work which will check the new standard, and store it in the internal
structure.

To handle mutual exclusion a mutex is introduced.

c277b60a08 V4L/DVB (13174): adv7180: Support for setting input status
Support for settings the input standard of the ADV7180.

When the input standard is set there is no use to ask the
chip for standard, therefore it is cached in the driver.

d31242943a V4L/DVB (13173): adv7180: Support for getting input status
This patch adds support to the ADV7180 driver to check the input
status.

Since the status is held in the same register as the input standard
a small restructuring of the code is done to reuse the code for
reading the register
