From 2e99b1b065fb9c6e771ce573cf6c2dbb52c14627 Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Thu, 6 Oct 2022 22:52:32 +0200 Subject: mfd: remove ucb1400 support The ucb1400 MFD driver and its gpio and touchscreen child drivers were only used on a few PXA machines that were unused for a while and are now removed. Removing these leaves the AC97 support as ALSA specific, no other drivers are now connected through this interface.
