The Renesas RZ/N1 device family PINCTRL node description.

Based on a patch originally written by Michel Pollet at Renesas.

Signed-off-by: Phil Edworthy <phil.edworthy@renesas.com>
Reviewed-by: Jacopo Mondi <jacopo+renesas@jmondi.org>
---
v6:
 - Instead of combining the pin nr and func into a single element, use
   a pair of 8-bit elements.

v5:
 - 'Optional generic properties' => 'Optional generic pinconf properties'

v4:
 - Add alternative way to use the pinmux prop.
 - Remove mention of gpios.

v3:
 - Use standard bindings
 - Change the way the functions are defined so it is easy to check
   against the hardware numbering.
 - Add functions for the MDIO source peripheral instead of using
   virtual pins.

v2:
 - Change filename to generic rzn1, instead of device specific.
 - Add "renesas,rzn1-pinctrl" compatible fallback string.
 - Example register size corrected.
 - Typos fixed.
 - Changes suggested by Jacopo Mondi.
 - rzn1-pinctrl.h squashed into this as requested by Rob Herring.

So the above is in response to Rob's comment on v4:

I'm not so much impressed by the "/bits/ 8" part.
No other pinctrl bindings uses this.
We do have RZA1_PINMUX() and STM32_PINMUX() macros.

Rob: Is this really what you intended?

Thanks!

Yes, but those aren't doing token pasting which was my complaint here.

Do whatever is most consistant. If you want a macro to shift fields, 
then fine.

+Renesas RZ/N1 SoC Pinctrl node description.
+
+Pin controller node
+-------------------
+Required properties:
+- compatible: SoC-specific compatible string "renesas,<soc-specific>-pinctrl"
+  followed by "renesas,rzn1-pinctrl" as fallback. The SoC-specific compatible
+  strings must be one of:
+	"renesas,r9a06g032-pinctrl" for RZ/N1D
+	"renesas,r9a06g033-pinctrl" for RZ/N1S
+- reg: Address base and length of the memory area where the pin controller
+  hardware is mapped to.
+- clocks: phandle for the clock, see the description of clock-names below.
+- clock-names: Contains the name of the clock:
+    "bus", the bus clock, sometimes described as pclk, for register accesses.
+
+Example:
+	pinctrl: pin-controller@40067000 {
+	    compatible = "renesas,r9a06g032-pinctrl", "renesas,rzn1-pinctrl";
+	    reg = <0x40067000 0x1000>, <0x51000000 0x480>;
+	    clocks = <&sysctrl R9A06G032_HCLK_PINCONFIG>;
+	    clock-names = "bus";
+	};
+
+Sub-nodes
+---------
+
+The child nodes of the pin controller node describe a pin multiplexing
+function.
+
+- Pin multiplexing sub-nodes:
+  A pin multiplexing sub-node describes how to configure a set of
+  (or a single) pin in some desired alternate function mode.
+  A single sub-node may define several pin configurations.
+  Please refer to pinctrl-bindings.txt to get to know more on generic
+  pin properties usage.
+
+  The allowed generic formats for a pin multiplexing sub-node are the
+  following ones:
+
+  node-1 {
+      pinmux = /bits/ 8 <PIN_NR MUX_FUNC>, <PIN_NR MUX_FUNC>, ... ;
+      GENERIC_PINCONFIG;
+  };
+
+  node-2 {
+      sub-node-1 {
+          pinmux = /bits/ 8 <PIN_NR MUX_FUNC>, <PIN_NR MUX_FUNC>, ... ;
+          GENERIC_PINCONFIG;
+      };
+
+      sub-node-2 {
+          pinmux = /bits/ 8 <PIN_NR MUX_FUNC>, <PIN_NR MUX_FUNC>, ... ;
+          GENERIC_PINCONFIG;
+      };
+
+      ...
+
+      sub-node-n {
+          pinmux = /bits/ 8 <PIN_NR MUX_FUNC>, <PIN_NR MUX_FUNC>, ... ;
+          GENERIC_PINCONFIG;
+      };
+  };
+
+  node-3 {
+      pinmux = /bits/ 8 <PIN_NR MUX_FUNC>, <PIN_NR MUX_FUNC>, ... ;
+      GENERIC_PINCONFIG;
+
+      sub-node-1 {
+          pinmux = /bits/ 8 <PIN_NR MUX_FUNC>, <PIN_NR MUX_FUNC>, ... ;
+          GENERIC_PINCONFIG;
+      };
+
+      ...
+
+      sub-node-n {
+          pinmux = /bits/ 8 <PIN_NR MUX_FUNC>, <PIN_NR MUX_FUNC>, ... ;
+          GENERIC_PINCONFIG;
+      };
+  };
+
+  Use the latter two formats when pins part of the same logical group need to
+  have different generic pin configuration flags applied. Note that the generic
+  pinconfig in node-3 does not apply to the sub-nodes.
+
+  Client sub-nodes shall refer to pin multiplexing sub-nodes using the phandle
+  of the most external one.
+
+  Eg.
+
+  client-1 {
+      ...
+      pinctrl-0 = <&node-1>;
+      ...
+  };
+
+  client-2 {
+      ...
+      pinctrl-0 = <&node-2>;
+      ...
+  };
+
+  Required properties:
+    - pinmux:
+      8-bit integer array consisting of PIN_NR pin number and MUX_FUNC pairs.
+      When a pin has to be configured in alternate function mode, use this
+      property to identify the pin by its global index, and provide its
+      alternate function configuration number.
+      When multiple pins are required to be configured as part of the same
+      alternate function they shall be specified as members of the same
+      argument list of a single "pinmux" property.
+      PIN_NR directly corresponds to the pl_gpio pin number and MUX_FUNC is
+      one of the alternate function identifiers defined in:
+      <include/dt-bindings/pinctrl/rzn1-pinctrl.h>
+      These identifiers collapse the IO Multiplex Configuration Level 1 and
+      Level 2 numbers that are detailed in the hardware reference manual into a
+      single number. The identifiers for Level 2 are simply offset by 10.
+      Additional identifiers are provided to specify the MDIO source peripheral.
+
+  Optional generic pinconf properties:
+    - bias-disable		- disable any pin bias
+    - bias-pull-up		- pull up the pin with 50 KOhm
+    - bias-pull-down		- pull down the pin with 50 KOhm
+    - bias-high-impedance	- high impedance mode
+    - drive-strength		- sink or source at most 4, 6, 8 or 12 mA
+
+  Example:
+  A serial communication interface with a TX output pin and an RX input pin.
+
+  &pinctrl {
+	pins_uart0: pins_uart0 {
+		pinmux = /bits/ 8 <
+			103 RZN1_FUNC_UART0_I	/* UART0_TXD */
+			104 RZN1_FUNC_UART0_I	/* UART0_RXD */
+		>;
+	};
+  };
+
+  Example 2:
+  Here we set the pull up on the RXD pin of the UART.
+
+  &pinctrl {
+	pins_uart0: pins_uart0 {
+		pinmux = /bits/ 8 <
+			103 RZN1_FUNC_UART0_I		/* UART0_TXD */
+		>;
+
+		pins_uart6_rx {
+			pinmux = /bits/ 8 <
+				104 RZN1_FUNC_UART0_I	/* UART0_RXD */
+			>;
+			bias-pull-up;
+		};
+	};
+  };
