pinctrl: Add pinctrl-aspeed-g4 driver

amboar · linusw · commit 524594d40153 · 2016-09-07T16:51:49.000+02:00
A subset of the pins and functions are exposed. The selection of functions and pins is driven by the development of OpenBMC[1] on the AST2400 SoC, particularly around booting the OpenPOWER Palmetto development machine.
