2021-01-14media: ccs: Make (non-)use of uninitialised variables more robustSakari Ailus1-4/+20
GCC with W=2 level of kernel compiler warnings warns about the use of uninitialised variables in a few locations. While these uninitialised variables were not used in reality, this still produced compiler warnings. Address this by assigning the variables to NULL and checking for NULL in places it is not expected, returning -EIO in that case. This provides at least some sanity checking at runtime as the compiler appears unable to do that at compile time.

2021-01-12media: ccs: Support and default to auto PHY controlSakari Ailus1-11/+43
CCS supports three variants of PHY timing control, auto, UI based and manual. The driver previously assumed UI based control that requires updating the link rate to the sensor. Now default to automatic control instead, and only write the link rate to the sensor in UI mode. If neither auto or UI control is supported, return an error in probe.

2021-01-12media: ccs: Hardware requires a delay after starting the clock of lifting resetSakari Ailus1-13/+16
A CCS compliant device requires a delay before the first I²C transaction after pulling xshutdown up or starting the external clock. This is what the driver does. However, if neither is actually there, there's no need for the delay. This also has the effect of removing an unnecessary delay on ACPI systems where ACPI is responsible for the power-up sequence.

2021-01-12media: i2c: Add support for the OV8865 image sensorPaul Kocialkowski3-0/+2986
The OV8865 is a 8 Mpx CMOS image sensor producing 3264x2448 at 30 fps. Other modes (including some with sub-sampling) are available too. It outputs 10-bit bayer CFA data through a MIPI CSI-2 interface with up to 4 lanes supported. Some register initialisation sequences are still needed for this driver, as they cover registers for which no documentation is available. This work is based on the first version of the driver submitted by Kévin L'hôpital, which was adapted to mainline from the Allwinner BSP. This version is a rewrite of the first version that matches the structure of the OV5648 driver, with explicit PLL configuration, all the necessary mode-specific fields, associatied registers and reduced static sequences. It was tested with the Banana Pi Camera Board v3 and the Banana Pi M3.
