75  * struct tegra_function - Tegra pinctrl mux function
77  * @groups: An array of pin groups that may select this function.
87  * struct tegra_pingroup - Tegra pin group
88  * @name		The name of the pin group.
89  * @pins		An array of pin IDs included in this pin group.
91  * @funcs		The mux functions which can be muxed onto this group.
92  * @mux_reg:		Mux register offset.
93  *			This register contains the mux, einput, odrain, lock,
95  * @mux_bank:		Mux register bank.
96  * @mux_bit:		Mux register bit.
97  * @pupd_reg:		Pull-up/down register offset.
98  * @pupd_bank:		Pull-up/down register bank.
99  * @pupd_bit:		Pull-up/down register bit.
100  * @tri_reg:		Tri-state register offset.
101  * @tri_bank:		Tri-state register bank.
102  * @tri_bit:		Tri-state register bit.
103  * @einput_bit:		Enable-input register bit.
104  * @odrain_bit:		Open-drain register bit.
128  * -1 in a *_reg field means that feature is unsupported for this group.
129  * *_bank and *_reg values are irrelevant when *_reg is -1.
130  * When *_reg is valid, *_bit may be -1 to indicate an unsupported feature.
132  * A representation of a group of pins (possibly just one pin) in the Tegra
133  * pin controller. Each group allows some parameter or parameters to be
134  * configured. The most common is mux function selection. Many others exist
135  * such as pull-up/down, tri-state, etc. Tegra's pin controller is complex;
178  * struct tegra_pinctrl_soc_data - Tegra pin controller driver configuration
179  * @ngpios:	The number of GPIO pins the pin controller HW affects.
180  * @pins:	An array describing all pins the pin controller affects.
185  * @functions:	An array describing all mux functions the SoC supports.
187  * @groups:	An array describing all pin groups the pin SoC supports.
