- * NXP (Philips) SCC+++(SCN+++) serial driver
- Required properties:
- - compatible: Should be "nxp,<ictype>". The supported ICs include sc2681,
- sc2691, sc2692, sc2891, sc2892, sc28202, sc68681 and sc68692.
- - reg: Address and length of the register set for the device.
- - interrupts: Should contain the interrupt number. If omitted,
- polling mode will be used instead, so "poll-interval" property should
- be populated in this case.
- Optional properties:
- - clocks: Phandle to input clock. If omitted, default IC frequency will be
- used instead.
- - poll-interval: Poll interval time in nanoseconds.
- - vcc-supply: The regulator supplying the VCC to drive the chip.
- - nxp,sccnxp-io-cfg: Array contains values for the emulated modem signals.
- The number of values depends on the UART-number in the selected chip.
- Each value should be composed according to the following rules:
- (LINE1 << SIGNAL1) | ... | (LINEX << SIGNALX), where:
- LINE - VALUE:
- OP0 - 1
- OP1 - 2
- OP2 - 3
- OP3 - 4
- OP4 - 5
- OP5 - 6
- OP6 - 7
- OP7 - 8
- IP0 - 9
- IP1 - 10
- IP2 - 11
- IP3 - 12
- IP4 - 13
- IP5 - 14
- IP6 - 15
- SIGNAL - VALUE:
- DTR - 0
- RTS - 4
- DSR - 8
- CTS - 12
- DCD - 16
- RNG - 20
- DIR - 24
- Example (Dual UART with direction control on OP0 & OP1):
- sc2892@10100000 {
- compatible = "nxp,sc2892";
- reg = <0x10100000 0x10>;
- poll-interval = <10000>;
- clocks = <&sc2892_clk>;
- vcc-supply = <&sc2892_reg>;
- nxp,sccnxp-io-cfg = <0x01000000 0x02000000>;
- };
