[PATCH 5/8] pinctrl-tz1090: add TZ1090 pinctrl driver

From: James Hogan
Date: Tue Apr 23 2013 - 10:36:05 EST

Add a pin control driver for the main pins on the TZ1090 SoC. This
doesn't include the low-power pins as they're controlled separately via
the Powerdown Controller (PDC) registers.

+ImgTec TZ1090 pin controller
+
+Required properties:
+- compatible: "img,tz1090-pinctrl"
+- reg: Should contain the register physical address and length of the pad
+ configuration registers (CR_PADS_* and CR_IF_CTL0).
+
+Please refer to pinctrl-bindings.txt in this directory for details of the
+common pinctrl bindings used by client devices, including the meaning of the
+phrase "pin configuration node".
+
+TZ1090's pin configuration nodes act as a container for an abitrary number of
+subnodes. Each of these subnodes represents some desired configuration for a
+pin, a group, or a list of pins or groups. This configuration can include the
+mux function to select on those pin(s)/group(s), and various pin configuration
+parameters, such as pull-up, drive strength, etc.
+
+The name of each subnode is not important; all subnodes should be enumerated
+and processed purely based on their content.
+
+Each subnode only affects those parameters that are explicitly listed. In
+other words, a subnode that lists a mux function but no pin configuration
+parameters implies no information about any pin configuration parameters.
+Similarly, a pin subnode that describes a pullup parameter implies no
+information about e.g. the mux function. For this reason, even seemingly boolean
+values are actually tristates in this binding: unspecified, off, or on.
+Unspecified is represented as an absent property, and off/on are represented as
+integer values 0 and 1.
+
+The exception to that rule is the select config. The CR_PADS_GPIO_SELECT{0,1,2}
+registers select between the serial interface (where an internal peripheral such
+as the SPI block controls the pin) and the GPIO interface (where the pin can be
+controlled by the other GPIO registers). This defaults to the GPIO interface for
+all pins, so muxing a function onto a pin group will set all pins to the serial
+interface. This can be overridden by claiming one of the pins as a GPIO, or
+explicitly setting the select config to override this behaviour (see below).
+
+Required subnode-properties:
+- pins : An array of strings. Each string contains the name of a pin or group.
+ Valid values for these names are listed below.
+
+Optional subnode-properties:
+- function: A string containing the name of the function to mux to the pin or
+ group. Valid values for function names are listed below, including which
+ pingroups can be muxed to them.
+- select: Integer, force the pin(s) to the GPIO interface so they cannot be
+ controlled by internal peripherals.
+ 0: don't force (internal peripheral will have control of the pin(s) if
+ they're muxed and not selected for GPIO use).
+ 1: force gpio mode (internal peripheral will not control the pin(s))
+- pull: Integer, representing the pull-down/up to apply to the pin(s).
+ 0: tri-state
+ 1: pull-up
+ 2: pull-down
+ 3: repeater
+- schmitt: Integer, enable or disable Schmitt trigger mode for the pins.
+ 0: no hysteresis
+ 1: schmitt trigger
+- slew-rate: Integer, control slew rate of pins.
+ 0: slow (half frequency)
+ 1: fast
+- drive-strength: Integer, control drive strength of pins.
+ 0: 2mA
+ 1: 4mA
+ 2: 8mA
+ 4: 12mA
+
+Note that many of these properties are only valid for certain specific pins
+or groups. See the TZ1090 TRM for complete details regarding which groups
+support which functionality. The Linux pinctrl driver may also be a useful
+reference.
+
+Valid values for pin and group names are:
+
+ gpio pins:
+
+ These all support select and pull (which can also be provided to any of the
+ groups below to set it for all gpio pins in that group).
+
+ They also all support the "default" function (if they cannot be individually
+ muxed, see pdm_d and spi1_cs2 mux groups below).
