2006-09-06 | Improved i2c performance on software bitbang algoritm | Mauro Carvalho Chehab | |
From: Mauro Carvalho Chehab <mchehab@infradead.org> Software I2C were using a very conservative value of udelay=16, meaning about 20Kbps. According with Philips I2C datasheet, the i2c should answer well for times at the order of 4.7 us. So, using udelay=5 should work for all devices. After this patch, the speed should be close to 66,67 Kbps, with the current kernel software bitbang, with 30/60 duty cycle. Anyway, added a new parameter (i2c_udelay) that would allow using conservative values, if eventually a hardware doesn't support the datasheet values. Thanks to Jean Delvare <khali@linux-fr.org> for pointing this improvement. Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org> | |||

2006-03-19 | Cleanup audio input handling | Hans Verkuil | |
From: Hans Verkuil <hverkuil@xs4all.nl> Cleanup audio input handling in bttv and tvaudio: - inputs were specified that were never used - mute was handled as a special input which led to confusing code - confusing naming made it difficult to see if the setting was for i2c or gpio. The old audiochip.h input names moved to tvaudio.h. Currently this is used both by tvaudio and msp3400 until the msp3400 implements the new msp3400-specific inputs. Detect in bttv the tvaudio and msp3400 i2c clients and use these client pointers to set the inputs directly instead of broadcasting the command. Removed AUDC_SET_INPUT. Now replaced by VIDIOC_S_AUDIO. This will be replaced again later by the new ROUTING commands. Removed VIDIOC_G_AUDIO implementations in i2c drivers: this command is a user level command and not to be used internally. It wasn't called at all anyway.
