* [media] drxk: remove a now unused variableMauro Carvalho Chehab2011-07-27

* [media] drxk: Add a fallback method for QAM parameter settingMauro Carvalho Chehab2011-07-27
| | | | | | | | | | | | | | | | | | | | | | | | The QAM standard is set using this scu_command: SCU_RAM_COMMAND_STANDARD_QAM | SCU_RAM_COMMAND_CMD_DEMOD_SET_PARAM The driver implements a version that has 4 parameters, however, Terratec H5 needs to break this into two separate commands, otherwise, DVB-C doesn't work. With this fix, scan is now properly working and getting the channel list: >>> tune to: 609000000:INVERSION_AUTO:5217000:FEC_3_4:QAM_256 >>> tuning status == 0x00 >>> tuning status == 0x07 >>> tuning status == 0x1f 0x0093 0x0026: pmt_pid 0x0758 (null) -- SporTV2 (running, scrambled) 0x0093 0x0027: pmt_pid 0x0748 (null) -- SporTV (running, scrambled) 0x0093 0x0036: pmt_pid 0x0768 (null) -- FX (running, scrambled) 0x0093 0x0052: pmt_pid 0x0788 (null) -- The History Channel (running, scrambled) Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
* [media] drxk: Improve the scu_command error messageMauro Carvalho Chehab2011-07-27
| | | | | | | | | | | | | | | | | Now, it outputs: [10927.639641] drxk: SCU_RESULT_INVPAR while sending cmd 0x0203 with params: [10927.646283] drxk: 02 00 00 00 10 00 07 00 03 02 .......... Better than ERROR -3. This happens with Terratec H5 firmware. It adds 2 new error conditions, and something useful to track what the heck is that. I suspect that the scu_command is dependent on the firmware revision. Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

* [media] drxk: Improves the UIO handlingMauro Carvalho Chehab2011-07-27
| | | | | | | | | | | The driver is too limited: it assumes that UIO is used only for controlling the antenna, and that only UIO-1 is in usage. However, from Terratec H7 driver [1], 3 UIO's can be used. In fact, it seems that H7 needs to use all 3. So, make the code generic enough to handle the most complex scenario. For now, only antena GPIO can be specified, but is is easier now to add the other GPIO/UIO needs. Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
* [media] drxk: Print detected configurationMauro Carvalho Chehab2011-07-27
| | | | | | | DRX-K configuration is interesting when writing/testing new devices. Add an info line showing the discovered info. Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
* [media] drxk: Fix the antenna switch logicMauro Carvalho Chehab2011-07-27
| | | | | | | | | Terratec H5 doesn't require to switch mode, but generates an error due to this logic. Also, GPIO's are board-dependent. So, add it at the board config struct. Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
* [media] drxk: change mode before calling the set mode routinesMauro Carvalho Chehab2011-07-27
| | | | | | | The set mode routines assume that state were changed to the new mode, otherwise, they'll fail. Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
* [media] drxk: Proper handle/propagate the error codesMauro Carvalho Chehab2011-07-27
| | | | | | | | | | | | | | | | | | | This driver is very big and complex. An error happening in the middle of any initialization may cause the frontend to not work. So, it needs to properly propagate error codes internally and to userspace. Also, printing the error codes at the places it happened helps to discover were's a bug at the code. Before this change, a do { } while (0) loop and lots of breaks inside were used to propagate errors. While this works, if there are loops inside other loops, it could be easy to forget to add another break, causing the error to not abort the function. Also, as not all functions were reporting errors, it is hard to discover why something failed. Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
* [media] drxk: Allow to disable I2C Bridge control switchMauro Carvalho Chehab2011-07-27
| | | | | | | On em28xx, tda18271C2 is accessible when the i2c port is not touched. Touching on it breaks the driver. Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
* [media] drxk: Add a parameter for the microcode nameMauro Carvalho Chehab2011-07-27
| | | | | | | | The microcode firmware provided on Terratec H5 seems to be different. Add a parameter to allow specifying a different firmware per-device. Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
* [media] drxk: Print an error if firmware is not loadedMauro Carvalho Chehab2011-07-27

* [media] drxk: Convert an #ifdef logic as a new config parameterMauro Carvalho Chehab2011-07-27
| | | | | | | | Instead of using #ifdef I2C_LONG_ADR for some devices, convert it into a parameter. Terratec H5 logs from the original driver seems to need this mode. Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
* [media] drxk: Move I2C address into a config structureMauro Carvalho Chehab2011-07-27
| | | | | | | | | | | Currently, the only parameter to be configured is the I2C address. However, Terratec H5 logs shows that it needs a different setting for some things, and it has its own firmware. So, move the addr into a config structure, in order to allow adding the required configuration bits. Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
* [media] drxk: remove _0 from read/write routinesMauro Carvalho Chehab2011-07-27
| | | | | | | | | | | | | | | | | | | | The normal 16-bits read routine is called as "Read16_0". This is due to a flags that could optionally be passed. Yet, on no places at the code, a flag is passed there. The same happens with 16-bits write and 32-read/write routines, and with WriteBlock. Also, using flags, is an exception: there's no place currently using flags, except for an #ifdef at WriteBlock. Rename the function as just "read16", and the one that requires flags, as "read16_flags". This helps to see where the flags are used, and also avoid using CamelCase on Kernel.
