2012-08-04[media] dvb_usb_v2: use pointers to propertiesAntti Palosaari5-78/+75
Use pointers to properties as device and adapter properties are constant. No need to embed and copy those structures. Signed-off-by: Antti Palosaari <crope@iki.fi> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

2012-08-04[media] dvb_usb_v2: use keyword const for USB ID tableAntti Palosaari1-1/+1
Let optimize that code to the text segment. Signed-off-by: Antti Palosaari <crope@iki.fi> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
2012-08-04[media] dvb_usb_v2: move few callbacks one level upAntti Palosaari3-25/+20
Move frontend_attach, tuner_attach, frontend_ctrl and streaming_ctrl from adapter to device. Signed-off-by: Antti Palosaari <crope@iki.fi> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
2012-08-04[media] dvb_usb_v2: Cypress firmware download moduleAntti Palosaari4-0/+162
Firmware handling routines for various Cypress chips. Cypress AN2135 Cypress AN2235 Cypress FX2 These were split out from general DVB USB module by Patrick Boettcher. I did only small changes. Signed-off-by: Antti Palosaari <crope@iki.fi> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
2012-08-04[media] dvb_usb_v2: suspend/resume stop/start USB streamingAntti Palosaari2-0/+45
Stop remote polling and USB streaming before suspend and resume those when back to normal operation. It is far away from complete implementation, but at least it does not hang system anymore on suspend while streaming is ongoing.

2012-08-04[media] dvb_usb_v2: add .disconnect() callbackAntti Palosaari2-0/+4

2012-08-04[media] dvb_usb_v2: probe/disconnect error handlingAntti Palosaari1-6/+4
In my understanding we never call .disconnect() when .probe() returns error. Change .probe() to return error all cases it cannot handle given interface and simplify .disconnect() handling. Signed-off-by: Antti Palosaari <crope@iki.fi> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

2012-08-04[media] af9015: use USB core soft_unbindAntti Palosaari1-0/+1
I think it is better to allow driver finish pending operations and disconnect device. Killing all ongoing USB transfers could have very bad effect, even break hardware in worst case. Signed-off-by: Antti Palosaari <crope@iki.fi> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
2012-08-04[media] af9015: switch to new DVB-USBAntti Palosaari3-1250/+775
Almost all hacks are now removed and much less code. Reducing af9015 driver code from 2084 to 1609, it is almost 500 LOC less! Signed-off-by: Antti Palosaari <crope@iki.fi> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
2012-08-04[media] dvb_usb_v2: enable compileAntti Palosaari7-64/+82
Compilation was disabled as it was failing with allyesconfig. Rename duplicate functions and enable building. Signed-off-by: Antti Palosaari <crope@iki.fi> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
2012-08-04[media] dvb_usb_v2: do not free resources until delayed init is doneAntti Palosaari2-13/+9
It was possible to free resources by unloading module while initialization was still ongoing on delayed work. Use PID to make decision on .disconnect() if caller is our work or some other as work also calls .disconnect() in error case. There could be better solution still...

2012-08-04[media] dvb_usb_v2: add .bInterfaceNumber matchAntti Palosaari2-1/+11
There is no USB match flag for used USB interface. It is rather common there is multiple interfaces offering different services. For example one for television and one for remote controller. Signed-off-by: Antti Palosaari <crope@iki.fi> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

2012-08-04[media] dvb_usb_v2: move I2C adapter code to different fileAntti Palosaari2-39/+31

2012-08-04[media] dvb_usb_v2: use Kernel logging (pr_debug/pr_err/pr_info)Antti Palosaari8-103/+71
Use Kernel logging insteads of own macros. Get rid of old debugs and use dynamic debug. Signed-off-by: Antti Palosaari <crope@iki.fi> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
2012-08-04[media] dvb_usb_v2: unregister all frontends in error caseAntti Palosaari1-36/+42
Unregister all if there is any error meet during frontend initialization. Signed-off-by: Antti Palosaari <crope@iki.fi> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
2012-08-04[media] dvb_usb_v2: remove usb_clear_halt()Antti Palosaari1-12/+0
Calling usb_clear_halt() during device init is not correct. 2 of 7 AF9015 devices I have timeouts next USB control message after usb_clear_halt(). It was originally performed between tuner_attach() and rc_query() and likely not causing problems since rc_query() is repeated continously. None could see it when first rc_query() failed... Secondly it was not called for .generic_bulk_ctrl_endpoint_response. Signed-off-by: Antti Palosaari <crope@iki.fi> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
2012-08-04[media] dvb_usb_v2: refactor delayed initAntti Palosaari2-99/+74
Move work to the struct dvb_usb_device that we can access it inside .disconnect(). Also many other minor changes. Signed-off-by: Antti Palosaari <crope@iki.fi> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
2012-08-04[media] dvb_usb_v2: ensure driver_info is not nullAntti Palosaari1-2/+11
It could be null in case of driver does not set it properly, like missing dynamic ID handling. Signed-off-by: Antti Palosaari <crope@iki.fi> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

2012-08-04[media] dvb_usb_v2: remove various unneeded variablesAntti Palosaari3-23/+3
Adapter priv is not really needed, use device priv instead. There is only driver or two using that. Device caps are not needed. There was only "has I2C adapter" capability defined. It is useless as we can see same just checking existence of i2c_algo callback. And also remove some totally not used at all variables.

2012-08-04[media] dvb_usb_v2: clean firmware downloading routinesAntti Palosaari3-195/+42
Remove Cypress USB-interface firmware downloading routines. That is common module and having single vendor chip routines in common module is wrong. Just move those elsewhere. Move single function out from the dvb_usb_firmware.c and remove that file. Signed-off-by: Antti Palosaari <crope@iki.fi> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
2012-08-04[media] dvb_usb_v2: delay firmware download as it blocks module initAntti Palosaari1-2/+75
Delay firmware download and whole driver initialization using workqueue. udev causes problems when blocking firmware download was done during module init. This will likely resolve all DVB USB firmware downloading issues we have had during recent years.

2012-08-04[media] dvb_usb_v2: move PID filters from frontend to adapterAntti Palosaari3-78/+55
Filtering given PIDs from the transport stream is done by the DVB USB bridge. It is highly possible there is limitations what kind of stream DVB USB bridge can PID filter, but it still does not make sense to define filters for each frontend as frontend could offer different stream types for different standards. Likely new way is to enable / disable PID filters are needed to make decision at runtime (callback). PID filters are quite legacy stuff as those are aimed cut stream smaller to fit for the USB1.1...

2012-08-04[media] dvb_usb_v2: add .get_ts_config() callbackAntti Palosaari3-63/+74
Add new callback in order to resolve used TS (MPEG transport stream) configuration. Normal TS is 188 byte payload only but there is currently 204 byte TS and raw TS supported too. Traditionally TS type was mapped as a frontend property but it does not work no longer after we changed from MFE (multi-frontend) to SFE (single-frontend). So it is not possible to map TS for the given FE as there could be only one FE instead of multiple.

2012-08-04[media] dvb_usb_v2: move (struct usb_data_stream) to one level upAntti Palosaari3-34/+28

2012-08-04[media] dvb_usb_v2: restore .firmware - pointer to nameAntti Palosaari2-6/+11

2012-08-04[media] dvb_usb_v2: implement .get_adapter_count()Antti Palosaari2-3/+17
