Add support for the pin controller on the UltraRISC DP1000 SoC. The controller provides mux selection for pins in ports A, B, C, D, and LPC. Ports A-D default to GPIO and support peripheral muxing. LPC pins can be switched to eSPI, but are not available as GPIOs. Basic pin configuration controls such as drive strength, pull-up, and pull-down are also supported.

Say Y to select the pinctrl driver for UltraRISC DP1000 SoC.
|
|
This pin controller allows selecting the mux function for
|
|
each pin. This driver can also be built as a module called
|
|
pinctrl-dp1000.
