v3 cover Add support for Terratec H6 version 2

That's the third version of this patch series. It adds support for Terratec H6 version 2.

As on the past version, this board is identified as "H5 MKII". There's a typo on the manufacturer's name, though:

[ 2970.196999] usb 1-1.5: Product: TERRATCE H5 MKII
[ 2970.197011] usb 1-1.5: Manufacturer: TERRATEC

While I wrote the patches, I don't have this verson of this device. The tests were run by an IRC user. Thanks!

The first patch is actually not needed for this device to work, but it fixes an issue: if something goes bad while reading the eeprom, the device probe aborts. As we don't really need to read the eeprom contents, we safely ignore any errors there.

While not certain why eeprom reading was failing with this device, I suspect that this particular device require some GPIO setting before being able to read its eeprom content.

The second patch in this series add support for the board.

v3: Improve patch documentation
v2: Ignore eeprom errors
v1: was assuming that eeprom would be at bus 1. such hipotesys
didn't confirm on the tests done today.

PATCH v3 1/2 em28xx: Ignore errors while reading from eeprom

While testing support for Terratec H6 rev. 2, it was noticed that reading from eeprom there causes a timeout error.

Apparently, this is due to the need of properly setting GPIOs.

In any case, the driver doesn't really require eeprom reading to succeed, as this is currently used only for debug.

So, Ignore such errors.

PATCH v3 2/2 em28xx: add support for new of Terratec H6

In reply to Mauro Carvalho Chehab

There's a new version of Terratec H6 with uses USB ID 0ccd:10b2. This version is similar to the old one (with is supported via the HTC entry), except that this one has the eeprom on the second bus.

On this board, one side of this board is labeled with:

	dvbc v2.0
The other side with:
	94V-0, MO2, RK-4221 with huge digits: 1107

With those patches, the board is properly detected:

...this can be simplified at least to

#if 0
.dvb_gpio = terratec_h5_digital, /* FIXME: probably wrong */
.tuner_gpio = terratec_h5_gpio,
#endif
.tuner_type = TUNER_ABSENT, /* Digital-only TDA18271HD */

Getting the device tested completely would of course be preferable.

Hmm... that might explain why eeprom reading works now:
The initial test was made without any board data.
In that case the em28xx driver uses the default i2c speed of 100kHz. The current timeout value EM28XX_I2C_XFER_TIMEOUT = 36ms might be enough when running at 400kHz, but not when running at 100kHz.

Frank
