2013-03-21[media] media/rc/imon.c: make send_packet() delay larger for 15c2:0036Kevin Baradon
Some imon devices (like 15c2:0036) need a higher delay between send_packet calls. Default value is still 5ms to avoid regressions on already working hardware. Also use interruptible wait to avoid load average going too high (and let caller handle signals).

2013-03-21[media] Corrected Oops on omap_vout when no manager is connectedFederico Fuga
If no manager is connected to the vout device, the omapvid_init() function fails. No error condition is checked, and the device is started. Later on, when irq is serviced, a NULL pointer dereference occurs. Also, the isr routine must be registered only if no error occurs, otherwise the isr triggers without the proper setup, and the kernel oops again. To prevent this, the error condition is checked, and the streamon function exits with error. Also the isr registration call is moved after the setup procedure is completed.

2013-03-21[media] xc5000: fix incorrect debug printnkDmitri Belimov
I found very small bug in xc5000 source. When set option debug=1 and listen a radio we see in dmesg xc5000: xc_SetTVStandard() Standard = M/N-NTSC/PAL-BTSC at all times. However, it should be, instead "FM Radio-INPUT1_MONO". That happens because xc5000_set_radio_freq() gets the correct value for VideoMode and AudioMode for radio and calls xc_SetTVStandard() where name of standard comes from the incorrect place priv->video_standard. This incorrect debug message makes debugging a little difficult. Signed-off-by: Dmitry Belimov <d.belimov@gmail.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
2013-03-21[media] soc_camera: remove two outdated selectsPaul Bolle
Release v2.6.30 removed the MT9M001_PCA9536_SWITCH and MT9V022_PCA9536_SWITCH Kconfig symbols, in commits 36034dc325ecab63c8cfb992fbf9a1a8e94738a2 ("V4L/DVB (11032): mt9m001: allow setting of bus width from board code") and e958e27adeade7fa085dd396a8a0dfaef7e338c1 ("V4L/DVB (11033): mt9v022: allow setting of bus width from board code"). These two commits removed all gpio related code from these two drivers. But they skipped removing their two selects of GPIO_PCA953X. Remove these now as they are outdated.

camera This patch fixes the issue that appears when mt9v024 camera is used with the mt9v022 soc camera driver. The minimum total row time is 690 columns (horizontal width + horizontal blanking). The minimum horizontal blanking is 61. Thus, when the window width is set below 627, horizontal blanking must be increased.

Commit f9bd5843658e18a7097fc7258c60fb840109eaa8 changed V4L2_CID_EXPOSURE_AUTO from boolean to enum, and commit af8425c54beb3c32cbb503a379132b3975535289 changed the creation of this control into a menu for the mt9m111. However, mt9m111_set_autoexposure() is still interpreting the value set for this control as a boolean, which also conflicts with the default value of this control set to V4L2_EXPOSURE_AUTO (0). This patch makes mt9m111_set_autoexposure() interpret the value set for V4L2_CID_EXPOSURE_AUTO as defined by enum v4l2_exposure_auto_type.

2013-03-21[media] siano: simplify firmware lookup logicMauro Carvalho Chehab
There are two ways to specify firmware for siano devices: a per-device ID and a per-device type. The per-device type logic is currently made by a 11x9 string table, sparsely filled. It is very hard to read the table at the source code, as there are too much "none" filling there ("none" there is a way to tell NULL). Instead of using such problematic table, convert it into an easy to read table, where the unused values will be defaulted to NULL. While here, also simplifies a little bit the logic and print a message if an user-selected mode doesn't exist. Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

That's the status report with Firmware 2.1, before adding support for sms2270 is: [22273.787218] smsdvb_onresponse: MSG_SMS_GET_STATISTICS_RES [22273.792592] IsRfLocked = 1 [22273.792592] IsDemodLocked = 1 ... [22273.792598] TransmissionMode = -64 ... (all unshown fields are filled with zeros) Of course, transmission mode being a negative number is wrong. So, we need to take a deeper look on it. With the debugfs patches applied, it is possible to see that, instead of filling StatisticsType with 5, and FullSize with the size of the payload (this is what happens with sms2270 and firmware 8.1), those fields are also initialized with zero: StatisticsType = 0 FullSize = 0 IsRfLocked = 1 IsDemodLocked = 1 IsExternalLNAOn = 0 SNR = 0 dB RSSI = 0 dBm InBandPwr = 0 dBm CarrierOffset = 0 Bandwidth = 0 Frequency = 0 Hz TransmissionMode = -64 ModemState = 0 GuardInterval = 0 SystemType = 0 PartialReception = 0 NumOfLayers = 0 SmsToHostTxErrors = 0 The data under "TransmissionMode" varies according with the signal, and it is negative. It also matches the value for InBandPwr when the tuner is on DVB-T (ok, signal doesn't lock, but the power level should be about the same with the antena fixed, and measured at about the same time). So, there's a very high chance that, when StatisticsType is zero, the signal strength is at the same position as Transmission Mode. So, discard all other parameters, and provide only signal/rf lock and signal strength if StatisticsType is 0, for ISDB-T. Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
