    Subject[PATCH v3 0/6] Driver for Si476x series of chips
    Date
    This is a third version of the patchset originaly posted here:
    https://lkml.org/lkml/2012/9/13/590

    Second version of the patch was posted here:
    https://lkml.org/lkml/2012/10/5/598

    To save everyone's time I'll repost the original description of it:

    This patchset contains a driver for a Silicon Laboratories 476x series
    of radio tuners. The driver itself is implemented as an MFD devices
    comprised of three parts:
    1. Core device that provides all the other devices with basic
    functionality and locking scheme.
    2. Radio device that translates between V4L2 subsystem requests into
    Core device commands.
    3. Codec device that does similar to the earlier described task, but
    for ALSA SoC subsystem.

    v3 of this driver has following changes:
    - All custom ioctls were moved to be V4L2 controls or debugfs files
    - Chip properties handling was moved to regmap API, so this should
    allow for cleaner code, and hopefully more consistent behaviour of
    the driver during switch between AM/FM(wich involevs power-cycling
    of the chip)

    I was hoping to not touch the code of the codec driver, since Mark has
    already appplied the previous version, but because of the last item I
    had to.

    Unfotunately, since my ARM setup runs only 3.1 kernel, I was only able
    to test this driver on a standalone USB-connected board that has a
    dedicated Cortex M3 working as a transparent USB to I2C bridge which
    was connected to a off-the-shelf x86-64 laptop running Ubuntu with
    custom kernel compile form git.linuxtv.org/media_tree.git. Which means
    that I was unable to test the change in the codec code, except for the
    fact the it compiles.


    Here is v4l2-compliance output for one of the tuners(as per Hans'
    request):
