This adds detection and activation for STV0367-based tuner hardware (namely CineCTv6 bridge cards and older DuoFlex CT addon modules). Utilises the extended stv0367 demod driver. TDA18212 i2c_client/regmap-api code was originally implemented by Antti Palosaari <crope@iki.fi> in a variant to update the ddbridge code from the vendor dddvb package (formal ack for these parts received). Original patch at [1]. When boards with STV0367 are cold-started, there might be issues with the I2C gate, causing the TDA18212 detection/probe to fail. For these demods, a workaround (tuner_tda18212_ping) is implemented which probes the tuner twice on this hardware constellation which will resolve the problem and put all components into a working state. Other demod/port types won't be retried.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
