Hauppauge produced a revision of ImpactVCBe using an 888, with a 25MHz crystal, instead of using the default third overtone 50Mhz crystal. Custom configuration of the cx25840 is required to load the firmware and properly decode video. This patch set add an extra clocking option to the cx25840 driver. If a cx2388x board is produced using non-default crystal, then clk_freq can be set in the board profile and then used by the cx25840 to set up the PLL's. To pass frequency, the cx23885 driver sets the cx25840 v4l subdev host data to a pointer to clk_freq. The only additional clock rate included is cx23888 with 25MHz crystal.
