| * | | | | V4L/DVB (3670): Fix typo in commentAdrian Bunk2006-04-02

| * | | | | V4L/DVB (3669): Configurable dma buffer size for saa7146-based budget dvb cardsIngo Schneider2006-04-02
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - Issue a warning when more than 80% of the DMA buffer is being used (probably due to bad IRQ latency). Warnings are rate-limited. - Introduce a new parameter 'bufsize' (in KByte) which increases the default DMA buffer of 188 KByte up to 1410 KByte (Activy: 564 KByte).

| * | | | | V4L/DVB (3667a): Fix SAP + stereo mode at msp3400Mauro Carvalho Chehab2006-04-02
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It should be V4L2_TUNER_MODE_LANG1_LANG2. What the code does is check if we are NTSC and a SAP channel is available. If so, then the msp3400 should switch to standard 0x21 if the user wants to hear the SAP channel, which is for audio modes LANG2 (aka SAP) and LANG1_LANG2 (bilingual). In the msp3400 driver STEREO is abused for bilingual in PAL. Bilingual never worked with NTSC in the past and I decided that I'd better not use the bad PAL example.

Previously this had been set to 1024 but unfortunately some I2C implementations can't transfer data in such big gulps. Specifically, the pvrusb2 driver has a hard limit of around 60 bytes, due to the encapsulation there of I2C traffic into USB messages. So we have to significantly reduce this parameter.

A note regarding i2c: The Atmel EEPROM hardware we use looks like an i2c device electrically, but is not i2c compliant at all from a functional perspective. We tried using the kernel's i2c support to talk to it, but failed. Normal i2c devices have a single 7-bit or 10-bit i2c address that they respond to. Valid 7-bit addresses range from 0x03 to 0x77. Addresses 0x00 to 0x02 and 0x78 to 0x7F are special reserved addresses (e.g. 0x00 is the "general call" address.) The Atmel device, on the other hand, responds to ALL addresses. It's designed to be the only device on a given i2c bus. A given i2c device address corresponds to the memory address within the i2c device itself. At least one reason why the linux core i2c stuff won't work for this is that it prohibits access to reserved addresses like 0x00, which are really valid addresses on the Atmel devices.
