Hans Verkuil authored
The V4L2_COLORSPACE_470_SYSTEM_M (aka NTSC 1953) colorspace has a different whitepoint (C) compared to Rec. 709 (D65). The Bradford method is the recommended method to compensate for that when converting a Rec. 709 color to an NTSC 1953 color. See http://www.brucelindbloom.com/index.html?Eqn_ChromAdapt.html for more details on the Bradford method. This patch updates the Rec. 709 to NTSC 1953 matrix so that it includes the chromatic adaptation as calculated by the Bradford method, and it recalculates the tpg_csc_colors table accordingly.

Every time compat32 encounters an unknown ioctl it will call pr_warn. However, that's very irritating since it is perfectly normal that this happens. For example, applications often try to call an ioctl to see if it exists, and if that's used with an older kernel where compat32 doesn't support that ioctl yet, then it starts spamming the kernel log. So replace pr_warn by pr_debug. Signed-off-by:

After adding the format check in try_fmt()/set_fmt(), we don't need any format check in configure_geometry(). So make configure_geometry() as void type. Signed-off-by:
-
Josh Wu authored
As in set_fmt() function we only need to know which format is been set, we don't need to access the ISI hardware in this moment. So move the configure_geometry(), which access the ISI hardware, to start_streaming() will make code more consistent and simpler. Signed-off-by:

Josh Wu authored
In the function configure_geometry(), we will setup the ISI CFG2 according to the sensor output format. It make no sense to just read back the CFG2 register and just set part of it. So just set up this register directly makes things simpler. Currently only support YUV format from camera sensor. Signed-off-by:

Hans Verkuil says: "The only place querystd can be called is in the QUERYSTD ioctl, all other ioctls should use the last set standard." So call the g_std() subdevice method instead of querystd() in the driver's set_fmt() method. Reported-by:

rcar_vin_set_fmt() defaults to PAL when the subdevice's querystd() method call fails (e.g. due to I2C error). This doesn't work very well when a camera being used outputs NTSC which has different order of fields and resolution. Let us stop pretending and return the actual error except when the querystd() method is not implemented, in which case we'll have to set the 'field' variable to V4L2_FIELD_NONE. Note that doing this would prevent video capture on at least Renesas Henninger/ Porter boards where I2C seems particularly buggy. Signed-off-by:

Since commit a483dcbf ("ARM: shmobile: lager: Remove legacy board support"), R-Car Gen2 SoCs are only supported in generic DT-only ARM multi-platform builds. The driver doesn't need to match platform devices by name anymore, hence remove the corresponding platform_device_id entry. Signed-off-by:

Since in soc_of_bind() it may use the of node's full name as the clk_name, and this full name may be longer than 32 characters, take at91 i2c sensor as an example, length is 34 bytes: /ahb/apb/i2c@f8028000/camera@0x30 So this patch increase the clk_name[] array size to 64. It seems big enough so far. Signed-off-by:
