2021-01-12media: ccs: Only do software reset if we have no hardware resetSakari Ailus1-4/+6
The driver always used software reset after the sensor's power sequence that includes a hardware reset if we have a reset GPIO. Do not use software reset if we just brought the sensor up from hardware reset state.

2021-01-12media: ccs: Don't change the I²C address just for software resetSakari Ailus1-8/+0

Also print out MSR registers written to the sensor. This isn't entirely optimal as the debug strings are produced even if they're not used but that isn't really a grave issue --- the I²C bus is very slow anyway.

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.

Most of the features of the hardware are supported, including: - Auto and manual exposition/gain - Auto and manual white balance - Horizontal and vertical flip - Test patterns But the following are still missing: - Debanding, based on power source frequency; - Exposition setting correlated to time units.

2021-01-12media: i2c: ov5670: Fix PIXEL_RATE minimum valueJacopo Mondi1-1/+2
The driver currently reports a single supported value for V4L2_CID_PIXEL_RATE and initializes the control's minimum value to 0, which is very risky, as userspace might accidentally use it as divider when calculating the time duration of a line.

2021-01-12media: ov5647: Fix return value from read/writeJacopo Mondi1-4/+8
The ov5647_read()/ov5647_write() return in case of success the number of bytes read or written respectively. This requires callers to check if the return value is less than zero to detect an error. Unfortunately, in several places, callers directly return the result of a read/write call, causing issues when the returned valued is checked to be different from zero to detect an error. Fix this by returning zero if i2c_master_send() and i2c_master_read() return a positive value (the number of bytes written or read).

2021-01-07media: ccs: Get static data version minor correctlySakari Ailus1-1/+1
Fix obtaining CCS static data version minor part correctly. Instead, the upper 8 bits were obtained from the major version number.

2021-01-07media: ccs-pll: Fix link frequency for C-PHYSakari Ailus1-7/+1
The highest fundamental frequency signal for C-PHY is half of the symbol rate which is similar to D-PHY. Take this into account in ccs-pll. Also remove the outdated comment.

2020-12-07media: ccs: Add support for obtaining C-PHY configuration from firmwareSakari Ailus1-0/+4
Try parsing the firmware also as C-PHY. Do this only after D-PHY as older firmware may not explicitly specify bus-type in which case D-PHY is the default. Signed-off-by: Sakari Ailus <sakari.ailus@linux.intel.com> Signed-off-by: Mauro Carvalho Chehab <mchehab+huawei@kernel.org>
