3 This binding describes the Top Level Mode Multiplexer block found in the
9 Definition: Should contain one of:
10 "qcom,msm8992-pinctrl",
11 "qcom,msm8994-pinctrl".
15 Value type: <prop-encoded-array>
16 Definition: the base address and size of the TLMM register space.
20 Value type: <prop-encoded-array>
21 Definition: should specify the TLMM summary IRQ.
23 - interrupt-controller:
26 Definition: identifies this node as an interrupt controller
31 Definition: must be 2. Specifying the pin number and flags, as defined
32 in <dt-bindings/interrupt-controller/irq.h>
37 Definition: identifies this node as a gpio controller
42 Definition: must be 2. Specifying the pin number and flags, as defined
43 in <dt-bindings/gpio/gpio.h>
47 Definition: see ../gpio/gpio.txt
49 - gpio-reserved-ranges:
51 Definition: see ../gpio/gpio.txt
53 Please refer to ../gpio/gpio.txt and ../interrupt-controller/interrupts.txt for
54 a general description of GPIO and interrupt bindings.
56 Please refer to pinctrl-bindings.txt in this directory for details of the
57 common pinctrl bindings used by client devices, including the meaning of the
58 phrase "pin configuration node".
60 The pin configuration nodes act as a container for an arbitrary number of
61 subnodes. Each of these subnodes represents some desired configuration for a
62 pin, a group, or a list of pins or groups. This configuration can include the
63 mux function to select on those pin(s)/group(s), and various pin configuration
64 parameters, such as pull-up, drive strength, etc.
67 PIN CONFIGURATION NODES:
69 The name of each subnode is not important; all subnodes should be enumerated
70 and processed purely based on their content.
72 Each subnode only affects those parameters that are explicitly listed. In
73 other words, a subnode that lists a mux function but no pin configuration
74 parameters implies no information about any pin configuration parameters.
75 Similarly, a pin subnode that describes a pullup parameter implies no
76 information about e.g. the mux function.
79 The following generic properties as defined in pinctrl-bindings.txt are valid
80 to specify in a pin configuration subnode:
84 Value type: <string-array>
85 Definition: List of gpio pins affected by the properties specified in
90 Supports mux, bias and drive-strength
92 sdc1_clk, sdc1_cmd, sdc1_data sdc1_rclk, sdc2_clk,
94 Supports bias and drive-strength
99 Definition: Specify the alternative function to be configured for the
100 specified pins. Functions are only valid for gpio pins.
