The bcm2835-unicam driver calls the clk_set_min_rate() function, which
is declared but not implemented on platforms that don't provide
COMMON_CLK. This causes linkage failures with some configurations.
Fix it by depending on COMMON_CLK. This only slightly restricts
compilation testing, but not usage of the driver as all platforms on
which the hardware can be found provide COMMON_CLK.

Say Y here to enable support for the BCM283x/BCM271x CSI-2 receiver.
|
|
This is a V4L2 driver that controls the CSI-2 receiver directly,
|
|
independently from the VC4 firmware.
|
|
|
|
This driver is mutually exclusive with the use of bcm2835-camera. The
|
|
firmware will disable all access to the peripheral from within the
|
|
firmware if it finds a DT node using it, and bcm2835-camera will
|
|
therefore fail to probe.
|
|
|
|
To compile this driver as a module, choose M here. The module will be
|
|
called bcm2835-unicam.
