+ * The R-Car DRIF is a receive only MSIOF like controller with an
+ * external master device driving the SCK. It receives data into a FIFO,
+ * then this driver uses the SYS-DMAC engine to move the data from
+ * the device to memory.
+ *
+ * Each DRIF channel DRIFx (as per datasheet) contains two internal
+ * channels DRIFx0 & DRIFx1 within itself with each having its own resources
+ * like module clk, register set, irq and dma. These internal channels share
+ * common CLK & SYNC from master. The two data pins D0 & D1 shall be
+ * considered to represent the two internal channels. This internal split
+ * is not visible to the master device.
+ *
+ * Depending on the master device, a DRIF channel can use
+ * (1) both internal channels (D0 & D1) to receive data in parallel (or)
+ * (2) one internal channel (D0 or D1) to receive data
+ *
+ * The primary design goal of this controller is to act as a Digital Radio
+ * Interface that receives digital samples from a tuner device. Hence the
+ * driver exposes the device as a V4L2 SDR device. In order to qualify as
+ * a V4L2 SDR device, it should possess a tuner interface as mandated by the
+ * framework. This driver expects a tuner driver (sub-device) to bind
+ * asynchronously with this device and the combined drivers shall expose
+ * a V4L2 compliant SDR device. The DRIF driver is independent of the
+ * tuner vendor.
+ *
+ * The DRIF h/w can support I2S mode and Frame start synchronization pulse mode.
+ * This driver is tested for I2S mode only because of the availability of
+ * suitable master devices. Hence, not all configurable options of DRIF h/w
+ * like lsb/msb first, syncdl, dtdl etc. are exposed via DT and I2S defaults
+ * are used. These can be exposed later if needed after testing.
