By default, isoc transfers are used if possible. With the new module parameter, bulk can be selected as the preferred USB transfer type. Signed-off-by:

The current enpoint logic ignores all bulk endpoints and uses a fixed mapping between endpint addresses and the supported data stream types (analog/audio/DVB): Ep 0x82, isoc => analog Ep 0x83, isoc => audio Ep 0x84, isoc => DVB Now that the code can also do bulk transfers, the endpoint logic has to be extended to also consider bulk endpoints. The new logic preserves backwards compatibility and reflects the endpoint configurations we have seen so far: Ep 0x82, isoc => analog Ep 0x82, bulk => analog Ep 0x83, isoc* => audio Ep 0x84, isoc => digital Ep 0x84, bulk => analog or digital** (*: audio should always be isoc) (**: analog, if ep 0x82 is isoc, otherwise digital) [mchehab@redhat.com: Fix a CodingStyle issue: don't break strings into separate lines] Signed-off-by:

Extend function em28xx_set_alternate: - use alternate setting 0 for bulk transfers as default - respect module parameter 'alt'=0 for bulk transfers - set max_packet_size to 512 bytes for bulk transfers [mchehab@redhat.com: Fix a CodingStyle issue: don't break strings into separate lines] Signed-off-by:

The URB data processing for DVB bulk transfers is very similar to what is done with isoc transfers, so create a common function that works with both transfer types based on the existing isoc function. Tested with device Hauppauge HVR-930c. Signed-off-by:

- rename em28xx_init_isoc to em28xx_init_usb_xfer - add parameter for isoc/bulk transfer selection which is passed to em28xx_alloc_urbs - rename local variable isoc_buf to usb_bufs Signed-off-by:

Rename the existing function for isoc transfers em28xx_init_isoc to em28xx_init_usb_xfer and extend it. URB allocation and setup is now done depending on the USB transfer type, which is selected with a new function parameter. Signed-off-by:

This function will be used to uninitialize USB bulk transfers, too. Also rename the local variable isoc_bufs to usb_bufs. Signed-off-by:

Also rename the corresponding field isoc_ctl in struct em28xx to usb_ctl. We will use this struct for USB bulk transfers, too. Signed-off-by:

Rename EM28XX_NUM_PACKETS to EM28XX_NUM_ISOC_PACKETS and EM28XX_DVB_MAX_PACKETS to EM28XX_DVB_NUM_ISOC_PACKETS to clarify that these values are used only for isoc usb transfers. Also use the term num_packets instead of max_packets, as this is how these values are used and called in struct urb. Signed-off-by:

em28xx_copy_video uses a wrong offset for the target buffer when copying the data from an USB isoc packet. This happens only for the second and all following lines in the packet. The reason why this bug doesn't cause image corruption with my test device (SilverCrest Webcam 1.3 MPix) is, that this device never sends any packets that cross the end of a line. I don't know if all devices behave like this, so this patch should be considered for stable. With the upcoming patches to add support for USB bulk transfers, em28xx_copy_video will be called once per URB, which will always trigger this bug. Signed-off-by:

When em28xx_ir_init() fails due to an configuration error, it frees the memory of struct em28xx_IR *ir, but doesn't set the corresponding pointer in the device struct to NULL. On device removal, em28xx_ir_fini() gets called, which then calls rc_unregister_device() with a pointer to freed memory.

Newer em28xx chipsets (em2874 and upper) are capable of supporting RC6 codes, on both mode 0 (command mode, 16 bits payload size, similar to RC5, also called "Philips mode") and mode 6a (OEM command mode, with offers a few alternatives with regards to the payload size). I don't have any mode 6a control ATM to test it, so, I opted to add support only to mode 0. After this patch, adding support to mode 6a should not be hard. Tested with a Philips television remote controller. Signed-off-by: -

By disabling the NEC parity check, it is possible to handle all 3 NEC protocol variants (32, 24 or 16 bits). Change the driver in order to handle all of them. Unfortunately, em2860/em2863 provide only 16 bits for the IR scancode, even when NEC parity is disabled. So, this change should affect only em2874 and newer devices, with provides up to 32 bits for the scancode. Tested with one NEC-16, one NEC-24 and one RC5 IR. Signed-off-by: -

I noticed that the EM28XX DVB driver doesn't auto select all of the appropriate DVB tuner modules required. In particular I needed DVB_LGDT3305 for my a340, but it looks like DVB_MT352 + DVB_S5H1409 were missing as well. Signed-Off-by:
