* [media] tda18271: fix bad calculation of main post divider byteMichael Krufky2011-04-191-10/+1
| | | | | | | | | | | R_MPD bit 3 does not depend on analog vs. digital. Just use (0x7f & pd) directly from the values in the main pll table. Thanks to Stefan Sibiga for pointing this out.

* [media] af9015: Fix max I2C message size when used with tda18271Mauro Carvalho Chehab2010-10-271-1/+1
| | | | | | | | | | | | | | | | | | | | | Changeset 1724c8fa7eb33d68898e060a08a8e6a88348b62f added an option to change the maximum I2C size to 8 bytes. However, it forgot to replace the previous usage at af9015 to use the newly defined macro value (TDA18271_16_BYTE_CHUNK_INIT). A latter changeset (e350d44fed8eb86a7192a579e3687fcd76a4645b) extended the possible values for .small_i2c field and, instead of using a random sequence of numbers, it used a number that makes more sense (e. g. the actual limit, in terms of bytes). However, as af9015 were using .small_i2c = 1, this become undefined, and the restriction of a max size of 16 was gone. While here, fix the reported msg size at tda18271-common.c.

* [media] tda18271: allow restricting max out to 4 bytesMauro Carvalho Chehab2010-10-211-25/+34
| | | | | | | | | | | | | | | By default, tda18271 tries to optimize I2C bus by updating all registers at the same time. Unfortunately, some devices doesn't support it. The current logic has a problem when small_i2c is equal to 8, since there are some transfers using 11 + 1 bytes. Fix the problem by enforcing the max size at the right place, and allows reducing it to max = 3 + 1.

* V4L/DVB (13214): tda18271: allow for i2c buses that cant send 16 bytes at onceMichael Krufky2009-12-051-2/+14
| | | | | | | | | There is already an option for sending 16 byte chunks rather that writing 39 bytes all at once during the tuner's initialization. Some i2c buses can't send 16 bytes at once, so create an option for sending 8 byte chunks.

If supplied a frequency out of range, the error must be returned to the caller (tda18271c1_rf_tracking_filter_calibration) so that it can decide whether or not to write to register EB14, RFC_CPROG[7:0] Signed-off-by: Michael Krufky <mkrufky@linuxtv.org> Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>

* V4L/DVB(7767): Move tuners to common/tunersMauro Carvalho Chehab2008-04-291-0/+666
There were several issues in the past, caused by the hybrid tuner design, since now, the same tuner can be used by drivers/media/dvb and drivers/media/video. Kconfig items were rearranged, to split V4L/DVB core from their drivers. Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
