* [media] tda18271-common: hold the I2C adapter during write transfersMauro Carvalho Chehab2012-10-071-33/+71
| | | | | | | | | | | | | | | | | | | | | | | The tda18271 datasheet says: "The image rejection calibration and RF tracking filter calibration must be launched exactly as described in the flowchart, otherwise bad calibration or even blocking of the TDA18211HD can result making it impossible to communicate via the I2C-bus." (yeah, tda18271 refers there to tda18211 - likely a typo at their datasheets) That likely explains why sometimes tda18271 stops answering. That is now happening more often on designs with drx-k chips, as the firmware is now loaded asyncrousnly there. While the above text doesn't explicitly tell that the I2C bus couldn't be used by other devices during such initialization, that seems to be a requirement there. So, let's explicitly use the I2C lock there, avoiding I2C bus share during those critical moments. Compile-tested only. Please test.

* [media] mt2063: properly handle return error codesMauro Carvalho Chehab2012-10-062-22/+18
| | | | | | | | | | | | | | | | | | | | | | | Fix a series of warnings when compiled with W=1: drivers/media/tuners/mt2063.c: In function 'mt2063_setreg': drivers/media/tuners/mt2063.c:290:2: warning: comparison of unsigned expression < 0 is always false [-Wtype-limits] ... drivers/media/tuners/mt2063.c:2013:2: warning: comparison of unsigned expression < 0 is always false [-Wtype-limits] drivers/media/tuners/mt2063.c:2271:14: warning: no previous prototype for 'tuner_MT2063_SoftwareShutdown' [-Wmissing-prototypes] drivers/media/tuners/mt2063.c:2286:14: warning: no previous prototype for 'tuner_MT2063_ClearPowerMaskBits' [-Wmissing-prototypes] Several of those warnings are real bugs: the error status code used to be unsigned, but they're assigned to negative error codes. Fix it by using unsigned int. While here, comment the two power management functions, while we don't add a code there to properly handle tuner suspend/resume.

* [media] tda18271: properly report read errors in tda18271_get_idMichael Krufky2012-10-021-1/+9
| | | | | | | | | Until now, if there is a read error in tda18271_get_id, the driver reports "Unknown device..." Instead, check the return value of tda18271_read_regs and display the appropriate error message.

* [media] tda18271: delay IR & RF calibration until init() if delay_cal is setMichael Krufky2012-10-022-0/+10
| | | | | | | | | | | if the configuration option 'delay_cal' is set, delay both IR & RF calibration until init() is called. both module option 'cal' or configuration option 'rf_cal_on_startup' will override this delay. it makes no sense to mix 'delay_cal' with 'rf_cal_on_startup' as these options conflict with each other.

* [media] tda18271: make 'low-power standby mode after attach' multi-instance safeMichael Krufky2012-10-011-3/+4
| | | | | | | | | | | | | Ensure that unnecessary features are powered down at the end of the attach() function on attach of the tuner's first instance. If the configuration requires the loop thru or xtout features, they will remain enabled. This must *only* be done after attaching the first instance of the tuner. If there are multiple instances of the tuner, the bridge driver will need to maintain power managament by itself.

| | | | | | | | | | | | | | This is initial support for the Asus MyCinema U3100Mini Plus. The driver in its current form gets detected and loads properly. Scanning using dvbscan works without problems, Locking onto a channel using tzap also works fine. Only playback using tzap -r + mplayer was tested and was fully functional. It uses the af9035 USB Bridge chip, with an af9033 demodulator. The tuner used is the FCI FC2580.
