+STMicroelectronics STi c8sectpfe binding
+============================================
+
+This document describes the c8sectpfe device bindings that is used to get transport
+stream data into the SoC on the TS pins, and into DDR for further processing.
+
+It is typically used in conjunction with one or more demodulator and tuner devices
+which converts from the RF to digital domain. Demodulators and tuners are usually
+located on an external DVB frontend card connected to SoC TS input pins.
+
+Currently 7 TS input (tsin) channels are supported on the stih407 family SoC.
+
+Required properties (controller (parent) node):
+- compatible : Should be "stih407-c8sectpfe"
+
+- reg : Address and length of register sets for each device in
+ "reg-names"
+
+- reg-names : The names of the register addresses corresponding to the
+ registers filled in "reg":
+ - c8sectpfe: c8sectpfe registers
+ - c8sectpfe-ram: c8sectpfe internal sram
+
+- clocks : phandle list of c8sectpfe clocks
+- clock-names : should be "c8sectpfe"
+See: Documentation/devicetree/bindings/clock/clock-bindings.txt
+
+- pinctrl-names : a pinctrl state named tsin%d-serial or tsin%d-parallel (where %d is tsin-num)
+ must be defined for each tsin child node.
+- pinctrl-0 : phandle referencing pin configuration for this tsin configuration
+See: Documentation/devicetree/bindings/pinctrl/pinctrl-binding.txt
+
+
+Required properties (tsin (child) node):
+
+- tsin-num : tsin id of the InputBlock (must be between 0 to 6)
+- i2c-bus : phandle to the I2C bus DT node which the demodulators & tuners on this tsin channel are connected.
+- rst-gpio : reset gpio for this tsin channel.
+
+Optional properties (tsin (child) node):
+
+- invert-ts-clk : Bool property to control sense of ts input clock (data stored on falling edge of clk).
+- serial-not-parallel : Bool property to configure input bus width (serial on ts_data<7>).
+- async-not-sync : Bool property to control if data is received in asynchronous mode
+ (all bits/bytes with ts_valid or ts_packet asserted are valid).
+
+- dvb-card : Describes the NIM card connected to this tsin channel.
+
+Example:
+
+/* stih410 SoC b2120 + b2004a + stv0367-pll(NIMB) + stv0367-tda18212 (NIMA) DT example) */
