1 NVIDIA Tegra114 pinmux controller
3 The Tegra114 pinctrl binding is very similar to the Tegra20 and Tegra30
4 pinctrl binding, as described in nvidia,tegra20-pinmux.txt and
5 nvidia,tegra30-pinmux.txt. In fact, this document assumes that binding as
6 a baseline, and only documents the differences between the two bindings.
9 - compatible: "nvidia,tegra114-pinmux"
10 - reg: Should contain the register physical address and length for each of
11 the pad control and mux registers. The first bank of address must be the
12 driver strength pad control register address and second bank address must
13 be pinmux register address.
15 Tegra114 adds the following optional properties for pin configuration subnodes:
16 - nvidia,enable-input: Integer. Enable the pin's input path. 0: no, 1: yes.
17 - nvidia,open-drain: Integer. Enable open drain mode. 0: no, 1: yes.
18 - nvidia,lock: Integer. Lock the pin configuration against further changes
19 until reset. 0: no, 1: yes.
20 - nvidia,io-reset: Integer. Reset the IO path. 0: no, 1: yes.
21 - nvidia,rcv-sel: Integer. Select VIL/VIH receivers. 0: normal, 1: high.
22 - nvidia,drive-type: Integer. Valid range 0...3.
24 As with Tegra20 and Terga30, see the Tegra TRM for complete details regarding
25 which groups support which functionality.
27 Valid values for pin and group names are:
31 These all support nvidia,function, nvidia,tristate, nvidia,pull,
32 nvidia,enable-input, nvidia,lock. Some support nvidia,open-drain,
33 nvidia,io-reset and nvidia,rcv-sel.
