   1 * Toshiba TC358743 HDMI-RX to MIPI CSI2-TX Bridge
   2
   3 The Toshiba TC358743 HDMI-RX to MIPI CSI2-TX (H2C) is a bridge that converts
   4 a HDMI stream to MIPI CSI-2 TX. It is programmable through I2C.
   5
   6 Required Properties:
   7
   8 - compatible: value should be "toshiba,tc358743"
   9 - clocks, clock-names: should contain a phandle link to the reference clock
  10                        source, the clock input is named "refclk".
  11
  12 Optional Properties:
  13
  14 - reset-gpios: gpio phandle GPIO connected to the reset pin
  15 - interrupts, interrupt-parent: GPIO connected to the interrupt pin
  16 - data-lanes: should be <1 2 3 4> for four-lane operation,
  17               or <1 2> for two-lane operation
  18 - clock-lanes: should be <0>
  19 - clock-noncontinuous: Presence of this boolean property decides whether the
  20                        MIPI CSI-2 clock is continuous or non-continuous.
  21 - link-frequencies: List of allowed link frequencies in Hz. Each frequency is
  22                     expressed as a 64-bit big-endian integer. The frequency
  23                     is half of the bps per lane due to DDR transmission.
