    Subject[PATCH 4.4 229/268] media: cx23885: Set subdev host data to clk_freq pointer
    Date
    4.4-stable review patch.  If anyone has any objections, please let me know.

    ------------------

    From: Brad Love <brad@nextdimension.cc>

    [ Upstream commit 5ceade1d97fc6687e050c44c257382c192f56276 ]

    Currently clk_freq is ignored entirely, because the cx235840 driver
    configures the xtal at the chip defaults. This is an issue if a
    board is produced with a non-default frequency crystal. If clk_freq
    is not zero the cx25840 will attempt to use the setting provided,
    or fall back to defaults otherwise.
