From 15711ba6ff197c3152c655dd9c55f5c1694e8272 Mon Sep 17 00:00:00 2001 From: Johnny Huang Date: Mon, 2 Dec 2019 16:44:32 +1030 Subject: [PATCH] pinctrl: aspeed-g6: Add AST2600 pinconf support The AST2600 pinconf is a little different from previous generations of ASPEED BMC SoCs in terms of architecture. The pull-down setting is per-pin setting now, and drive-strength support 4 kind of value (e.g. 4ma, 8ma, 12ma, 16ma).
