+Qualcomm Technologies, Inc. SDM660 TLMM block
+
+This binding describes the Top Level Mode Multiplexer block found in the
+SDM660 platform.
+
+- compatible:
+ Usage: required
+ Value type: <string>
+ Definition: must be "qcom,sdm660-pinctrl" or
+ "qcom,sdm630-pinctrl".
+
+- reg:
+ Usage: required
+ Value type: <prop-encoded-array>
+ Definition: the base address and size of the TLMM register space.
+
+- interrupts:
+ Usage: required
+ Value type: <prop-encoded-array>
+ Definition: should specify the TLMM summary IRQ.
+
+- interrupt-controller:
+ Usage: required
+ Value type: <none>
+ Definition: identifies this node as an interrupt controller
+
+- #interrupt-cells:
+ Usage: required
+ Value type: <u32>
+ Definition: must be 2. Specifying the pin number and flags, as defined
+ in <dt-bindings/interrupt-controller/irq.h>
+
+- gpio-controller:
+ Usage: required
+ Value type: <none>
+ Definition: identifies this node as a gpio controller
+
+- gpio-ranges:
+ Usage: required
+ Value type: <prop-encoded-array>
+ Definition: Specifies the mapping between gpio controller and
+ pin-controller pins.
+
+- #gpio-cells:
+ Usage: required
+ Value type: <u32>
+ Definition: must be 2. Specifying the pin number and flags, as defined
+ in <dt-bindings/gpio/gpio.h>
+
+Please refer to ../gpio/gpio.txt and ../interrupt-controller/interrupts.txt for
+a general description of GPIO and interrupt bindings.
+
+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".
+
+The pin configuration nodes act as a container for an arbitrary 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.
+
+
+PIN CONFIGURATION NODES:
+
+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.
+
+
+The following generic properties as defined in pinctrl-bindings.txt are valid
+to specify in a pin configuration subnode:
+
+- pins:
+ Usage: required
+ Value type: <string-array>
+ Definition: List of gpio pins affected by the properties specified in
+ this subnode. Valid pins are:
+ gpio0-gpio113,
+ Supports mux, bias and drive-strength
+ sdc1_clk, sdc1_cmd, sdc1_data sdc2_clk, sdc2_cmd, sdc2_data sdc1_rclk,
+ Supports bias and drive-strength
+
+- function:
+ Usage: required
+ Value type: <string>

+ specified pins. Functions are only valid for gpio pins.
