Oh, no! I just merged the v3 patch series. I manually fixed the
points that Antti has made.

I'm also testing it already.

Could you, instead, rebase it on the top of my merge?

I added it at:
ssh://linuxtv.org/git/mchehab/experimental.git cx231xx

While I'm still at the test phases.

[PATCH v4 00/14] cx231xx: Use muxed i2c adapters instead of custom switching

2014-10-30 Thread Matthias Schwarzott
Hi!

This time the series got only small updates from Antti's review.

Additionally I added a patch to no longer directly modify
the content of the port3 switch bit in PWR_CTL_EN (from function 
cx231xx_set_power_mode).

Now there are two places where I wonder what happens:
1. cx231xx_set_Colibri_For_LowIF writes a fixed number into all 8bit parts of 
PWR_CTL_EN
   What is this for?
2. I guess, cx231xx_demod_reset should reset the digital demod. For this it 
should toggle the bits 0 and 1 of PWR_CTL_EN. 
   But instead it touches but 8 and 9.
   Does someone know what this is?

3. Is remembering the last status of the port3 bit working good enough?
   Currently it is only used for the is_tuner hack function.

Regards
Matthias
