Subject: [PATCH v2 10/12] cx231xx: Add i2c device analog tuner support
Date: Wed, 27 Feb 2019 12:27:44 -0600	[thread overview]
Message-ID: <1551292066-29574-11-git-send-email-brad@nextdimension.cc> (raw)
In-Reply-To: <1551292066-29574-1-git-send-email-brad@nextdimension.cc>

The boards listed below use i2c device drivers and have
tuner_type equal TUNER_ABSENT. This means additional support
is required to enable the analog tuning capability, a case
statement is used to identify these models.

Models with analog tuning enabled:
- CX231XX_BOARD_HAUPPAUGE_930C_HD_1114xx (tested)
- CX231XX_BOARD_HAUPPAUGE_935C (tested)
- CX231XX_BOARD_HAUPPAUGE_955Q (tested)
- CX231XX_BOARD_HAUPPAUGE_975 (tested)
- CX231XX_BOARD_EVROMEDIA_FULL_HYBRID_FULLHD (untested)

The EvroMedia model was added, since it uses the si2157
tuner and the board profile claims it has analog inputs.

Changes since v1:
- remove __func__ from dev_dbg macros
