5     Renesas R-Car Pin Function Controller node
6     This binding gives a base representation of the R-Car pins configuration.
7     The R-Car pin controller is a singleton node responsible for controlling
8     pin function selection and pin properties. For example, you can use this
9     node to route CAN0 TX A to pin 'RD', and enable pull-up resistor as well
19     All device pin configurations should be placed in child nodes of the
21       /* You can put this in places like a board-pinctrl.dtsi file in
25       /* include pre-defined pins and functions for the SoC used by the board */
26       #include <dt-bindings/pinctrl/renesas/pinctrl-r8a77951.h>
29         /* configuration for can0 data a tx default state */
32           pin = <PIN_RD FUNC_CAN0_TX_A>;
34         /* configuration for can0 data a rx default state */
37           pin = <PIN_RD_WR FUNC_CAN0_RX_A>;
41     The 'can0_data_a_tx_default' child node encodes the pin configurations
42     for a particular state of a device; in this case, the default
43     (that is, active) state. You would specify the low-power configuration for
46     A pin configuration can also specify pin properties such as the
47     'bias-pull-up' property. Here is a list of supported standard pin
50     - bias-disable
51     - bias-pull-down
52     - bias-pull-up
53     - drive-strength
54     - power-source
56     To link pin configurations with a device, use a pinctrl-N property for some
59       #include "board-pinctrl.dtsi"
62         pinctrl-0 = <&can0_data_a_tx_default &can0_data_a_rx_default>;
63         pinctrl-1 = <&can0_data_a_tx_sleep &can0_data_a_rx_sleep>;
64         pinctrl-names = "default", "sleep";
