* [media] ov2640: print error if devm_*_optional*() failsMauro Carvalho Chehab2017-04-251-6/+20
| | | | | | | | | | devm_gpiod_get_optional() can return -ENOSYS if GPIOLIB is disabled, causing probe to fail. Warn the user if this happens.

* [media] ov2640: fix vflip controlFrank Schaefer2017-04-191-2/+4
| | | | | | | | | | | | | | | | | | | | | | | | | Enabling vflip currently causes wrong colors. It seems that (at least with the current sensor setup) REG04_VFLIP_IMG only changes the vertical readout direction. Because pixels are arranged RGRG... in odd lines and GBGB... in even lines, either a one line shift or even/odd line swap is required, too, but apparently this doesn't happen. I finally figured out that this can be done manually by setting REG04_VREF_EN. Looking at hflip, it turns out that bit REG04_HREF_EN is set there permanetly, but according to my tests has no effect on the pixel readout order. So my conclusion is that the current documentation of sensor register 0x04 is wrong (has changed after preliminary datasheet version 2.2). I'm pretty sure that automatic vertical line shift/switch can be enabled, too, but until anyone finds ot how this works, we have to stick with manual switching.

| | | | | | | | | | | | | | | | | According to ov2640 software application notes, there are two Automatic White Balance (AWB) modes, which are selected by DSP register 0xc7: 1) Simple AWB: assumes the average color is gray + independent from lens - doesn't work well if captured area contains unbalanced colors (e.g. large blue background) 2) Advanced AWB: uses color temperature information + more accurate, works with all image contents - lens specific, requires calibration Signed-off-by: Frank Schäfer <fschaefer.oss@googlemail.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>

* [media] ov2640: make GPIOLIB an optional dependencyMauro Carvalho Chehab2017-04-192-2/+5
| | | | | | | | | | | | | | As warned by kbuild test robot: warning: (VIDEO_EM28XX_V4L2) selects VIDEO_OV2640 which has unmet direct dependencies (MEDIA_SUPPORT && VIDEO_V4L2 && I2C && GPIOLIB && MEDIA_CAMERA_SUPPORT) The em28xx driver can use ov2640, but it doesn't depend (or use) the GPIOLIB in order to power off/on the sensor. So, as we want to allow both usages with and without GPIOLIB, make its dependency optional.

* [media] cec: Kconfig cleanupHans Verkuil2017-04-191-6/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | The Kconfig options for the CEC subsystem were a bit messy. In addition there were two cec sources (cec-edid.c and cec-notifier.c) that were outside of the media/cec directory, which was weird. Move those sources to media/cec as well. The cec-edid and cec-notifier functionality is now part of the cec module and these are no longer separate modules. Also remove the MEDIA_CEC_EDID config option and include it with the main CEC config option (which defined CEC_EDID anyway). Added static inlines to cec-edid.h for dummy functions when CEC_CORE isn't defined. CEC drivers should now depend on CEC_CORE. CEC drivers that need the cec-notifier functionality must explicitly select CEC_NOTIFIER. The s5p-cec and stih-cec drivers depended on VIDEO_DEV instead of CEC_CORE, fix that as well.

| | | | | | | | | | | | | | | | | | | | | | | The I2C core always reports a MODALIAS of the form i2c:<foo> even if the device was registered via OF, this means that exporting the OF device ID table device aliases in the module is not needed. But in order to change how the core reports modaliases to user-space, it's better to export it.

| | | | | | | | | | | | | Even if bus is not hot-pluggable, devices can be unbound from the driver via sysfs, so we should not be using __exit annotations on remove() methods. The only exception is drivers registered with platform_driver_probe() which specifically disables sysfs bind/unbind attributes.

|/ | | | | | | | | | | | | | | | | | | | | | | | While testing with CONFIG_UBSAN, I got this warning: drivers/media/i2c/tc358743.c: In function 'tc358743_probe': drivers/media/i2c/tc358743.c:1930:1: error: the frame size of 2480 bytes is larger than 2048 bytes [-Werror=frame-larger-than=] The problem is that the i2c_rd8/wr8/rd16/... functions in this driver pass a pointer to a local variable into a common function, and each call to one of them adds another variable plus redzone to the stack. I also noticed that the way this is done is broken on big-endian machines, as we copy the registers in CPU byte order. To address both those problems, I'm adding two helper functions for reading a register of up to 32 bits with correct endianess and change all other functions to use that instead. Just to be sure we don't get the problem back with changed optimizations in gcc, I'm also marking the new functions as 'noinline', although my tests with gcc-7 don't require that.

* [media] tc358743: Disable HDCP with "manual HDCP authentication" bitMats Randgaard2017-02-032-20/+13
| | | | | | | | | | | | | | | | | | | | | | | | Originally Toshiba told us that the only way to disable HDCP was to set the receiver in repeater mode, that would make the authentication fail because of missing software support. It has worked fine with all the sources we and our customers has used, until it was reported problems with Apple MacBook (Retina, 12-inch, Early 2015) (https://support.apple.com/kb/SP712?locale=en_US&viewlocale=en_US) with Apple A1612 USB type-C multiport adapter (http://www.apple.com/shop/product/MJ1K2AM/A/usb-c-digital-av-multiport-adapter) Finally Toshiba came up with a hidden bit that is named "Manual HDCP authentication". In this patch the original "repeater mode" concept is removed, and the new bit is set instead. With his patch HDCP is disabled when connected to the Apple MacBook and all other sources we have tested so far. The Apple MacBook is constantly trying to authenticate, but fails and continues to transmit unencrypted video.

* [media] tc358743: Do not read number of CSI lanes in use from chipMats Randgaard2017-02-031-7/+7
| | | | | | | | | | | | | | | The number of CSI lanes that should be used is set to the CSI_CONTROL register by indirectly writing to the CSI_CONFW register. When the number of lanes is read back from the CSI_CONTROL register the value is usually correct, but we have seen that it suddenly is 1 for a short moment before the correct value is restored again. Toshiba have not figured out why that happen, but we have found it safer to store the value in the driver.
