From d795cb51dfee2a859b5585101a4e3ce5bc9bff75 Mon Sep 17 00:00:00 2001 From: Sebastian Reichel Date: Mon, 15 May 2017 11:24:27 +0200 Subject: [PATCH] pinctrl: mcp23s08: drop pullup config from pdata mcp23s08 support configuration of the pullups using the pinconf framework. This removes the custom pullup configuration from platform data, which has no upstream users.
