14  * TX_HIZ_UNUSED:   TX pin high-impedance during unused slots.
15  * TX_HIZ_DISABLED: TX pin high-impedance when all channels disabled.
21  * Optional GPIOX Sub-nodes:
22  *  The cs35l45 node can have up to three "cirrus,gpio-ctrlX" ('X' = [1,2,3])
23  *  sub-nodes for configuring the GPIO pins.
25  * - gpio-dir : GPIO pin direction. Valid only when 'gpio-ctrl'
30  * - gpio-lvl : GPIO level. Valid only when 'gpio-ctrl' is 1 and 'gpio-dir' is 0.
35  * - gpio-op-cfg : GPIO output configuration. Valid only when 'gpio-ctrl' is 1
36  *   and 'gpio-dir' is 0.
41  * - gpio-pol : GPIO output polarity select. Valid only when 'gpio-ctrl' is 1
42  *   and 'gpio-dir' is 0.
44  *    0 = Non-inverted, Active High (Default)
47  * - gpio-invert : Defines the polarity of the GPIO pin if configured
53  * - gpio-ctrl : Defines the function of the GPIO pin.
57  *   1 = Pin acts as a GPIO, direction controlled by 'gpio-dir'
59  *   3-7 = Reserved
63  *   1 = Pin acts as a GPIO, direction controlled by 'gpio-dir'
66  *   4 = Pin acts as push-pull output INT. Active low.
67  *   5 = Pin acts as push-pull output INT. Active high.
72  *   1 = Pin acts as a GPIO, direction controlled by 'gpio-dir'
