Hi,
This patch:
1. adds explicit support for the FQ1216LME MK3
2. points the tveeprom module to the FQ1216LME MK3 entry for EEPROMs
claiming FQ1216LME MK3 and MK5.
3. refactors some code in simple_post_tune() because
a. I needed to set the Auxillary Byte, as did TUNER_LG_TDVS_H06XF, so I
could set the TUA6030 TOP to external AGC per the datasheet.
b. I wanted to do fast tuning while managing PLL phase noise, like the
TUNER_MICROTUNE_4042FI5 was already doing.
Hermann & Dmitri,
I think what is done for setting the charge pump current for the
TUNER_MICROTUNE_4042FI5 & FQ1216LME_MK3 in this patch is better than
fixing the control byte to a constant value of 0xce.
Comments?
Regards,
Andy
