This patch removes the dependency on an obsoleted soc_camera from ov9640 driver and changes the code to be a standalone v4l2 async subdevice. It also adds GPIO allocations for power and reset signals (as they are not handled by soc_camera now). The values for waiting on GPIOs (reset and power) settling down were taken from the datasheet (> 1 ms after HW/SW reset). The upper limit was chosen as an arbitrary value. Also one occurrence of mdelay() was changed to msleep(). The delays were successfully tested on a real hardware. The patch makes ov9640 sensor again compatible with the pxa_camera driver.

Initial part of ov9640 transition from soc_camera subsystem to a standalone v4l2 subdevice. The soc_camera version seems to be used only in Palm Zire72 and in (the future) HTC Magician. On these two devices the support is broken as pxa_camera driver doesn't use soc_camera anymore. The other mentions from git grep are "TODOs" (in board-osk.c) or chip names for unsupported sensors on HW which doesn't use soc_camera at all (irelevant). Copy the driver files from soc_camera and mark the original ones in the Kconfig description as obsoleted. Add config option VIDEO_OV9640 to the build files in drivers/media/i2c. Signed-off-by:

The following commits: commit f6dd927f ("[media] media: ov7670: calculate framerate properly for ov7675") commit 04ee6d92 ("[media] media: ov7670: add possibility to bypass pll for ov7675") introduced the ability to bypass PLL multiplier and use input clock (xvclk) as pixel clock output frequency for ov7675 sensor. PLL is bypassed using register DBLV[7:6], according to ov7670 and ov7675 sensor manuals. Macros used to set DBLV register seem wrong in the driver, as their values do not match what reported in the datasheet. Fix by changing DBLV_* macros to use bits [7:6] and set bits [3:0] to default 0x0a reserved value (according to datasheets). While at there, remove a write to DBLV register in "ov7675_set_framerate()" that over-writes the previous one to the same register that takes "info->pll_bypass" flag into account instead of setting PLL multiplier to 4x unconditionally. And, while at there, since "info->pll_bypass" is only used in set/get_framerate() functions used by ov7675 only, it is not necessary to check for the device id at probe time to make sure that when using ov7670 "info->pll_bypass" is set to false.

This commit corrects max and step values for v4l2 control for V4L2_CID_JPEG_RESTART_INTERVAL. Max should be 0xffff and step should be 1. It was found by using v4l2-compliance tool and checking result of VIDIOC_QUERY_EXT_CTRL/QUERYMENU test. Previously it was complaining that step was bigger than difference between max and min.

The driver fixed the TXA CSI-2 transmitter in 4-lane mode while it could operate using 1-, 2- and 4-lanes. Update the driver to support all available modes. The driver makes use of large tables of static register/value writes when powering up/down the TXA and TXB transmitters which include the write to the NUM_LANES register. By converting the tables into functions and using parameters the power up/down functions for TXA and TXB power up/down can be merged and used for both transmitters. Signed-off-by:

The adv748x CSI-2 transmitters TXA and TXB can use different number of lanes to transmit data. In order to be able to configure the device correctly this information need to be parsed from device tree and stored in each TX private data structure.

The locking implemented in the async notifier callbacks are unnecessary as the global list_lock in v4l2-async.c is held whenever one of the callbacks are called. The locking in itself is not harmful however it produces a LOCKDEP warning between the global v4l2-async list_lock and the rcar-vin local locking schema. Remove the rcar-vin locking for the async callbacks to reduce complexity and silent the false LOCKDEP warning. Signed-off-by:

Previously when doing format enumeration, it was returning all formats supported by driver, even if they're not supported by hw. Add missing check for fmt_ver_flag, so it'll be fixed and only those supported by hw will be returned. Similar thing is already done in s5p_jpeg_find_format. It was found by using v4l2-compliance tool and checking result of VIDIOC_ENUM_FMT/FRAMESIZES/FRAMEINTERVALS test and using v4l2-ctl to get list of all supported formats.
