2014-01-07[media] ad9389b: retry setup if the state is inconsistentMartin Bugge1-1/+26
Retry setup if the device is powered off when it should be powered on. This state can be caused by rapid hotplug toggles. Signed-off-by: Martin Bugge <marbugge@cisco.com> Signed-off-by: Hans Verkuil <hans.verkuil@cisco.com> Signed-off-by: Mauro Carvalho Chehab <m.chehab@samsung.com>
2014-01-07[media] ad9389b: remove rx-sense irq dependencyMartin Bugge1-80/+58
Removed dependency on rx-sense interrupt, it's a leftover from obsolete code. Removing this simplifies the code. Signed-off-by: Martin Bugge <marbugge@cisco.com> Signed-off-by: Hans Verkuil <hans.verkuil@cisco.com> Signed-off-by: Mauro Carvalho Chehab <m.chehab@samsung.com>

2013-08-24[media] ad9389b: set is_private only after successfully creating all controlsHans Verkuil1-5/+5
is_private was set right after creating each control, but the control pointer might be NULL in case of an error. Set it after all controls were successfully created, since that guarantees that all control pointers are non-NULL.

2013-08-24[media] v4l2-dv-timings: add callback to handle exceptionsHans Verkuil1-3/+4
In most cases the v4l2_bt_timings_cap struct has all the information necessary to determine valid timings, but occasionally there are exceptions. Add a callback function to be able to test for those exceptions. Signed-off-by: Hans Verkuil <hans.verkuil@cisco.com> Signed-off-by: Mauro Carvalho Chehab <m.chehab@samsung.com>
2013-08-24[media] v4l2-dv-timings: rename v4l2_dv_valid_timings to v4l2_valid_dv_timingsHans Verkuil1-1/+1

2013-08-24[media] adv7604/ad9389b/ths8200: decrease min_pixelclock to 25MHzHans Verkuil1-1/+1
The CEA-861 standard allows for the 640x480 format at 25.175 MHz. Ensure that that's allowed according to the struct v4l2_bt_timings_cap. Signed-off-by: Hans Verkuil <hans.verkuil@cisco.com> Signed-off-by: Mauro Carvalho Chehab <m.chehab@samsung.com>

2013-08-24[media] ad9389b: change initial register configuration in ad9389b_setup()Mats Randgaard1-5/+3
- register 0x17: CSC scaling factor was set to +/- 2.0. This register is set by ad9389b_csc_conversion_mode() to the right value. - register 0x3b: bits for pixel repetition and CSC was set to zero, but that is the default value.

2013-08-18[media] v4l2: move dv-timings related code to v4l2-dv-timings.cHans Verkuil1-0/+1
v4l2-common.c contained a bunch of dv-timings related functions. Move that to the new v4l2-dv-timings.c which is a more appropriate place for them. There aren't many drivers that do HDTV, so it is a good idea to separate common code related to that into a module of its own.

2012-09-13[media] ad9389b: driver for the Analog Devices AD9389B video encoderHans Verkuil1-0/+1328
Initial version of this driver. The full datasheets are available from the Analog Devices website: http://ez.analog.com/docs/DOC-1741 Not all features of the receiver are supported by this driver for various reasons. Most notably: - No CEC support (the CEC API needs a lot more discussion) - No HDCP repeater support (we don't use that either) I'm sure that there are more things missing, but this driver does work well for our hardware. Note that I am using the register addresses instead of register names: the datasheet containing the register descriptions is organized by register address. Using names would make the datasheet lookup very hard. An attempt was made to try and document what is being done when registers are used instead.
