Subject: [PATCH RFC 14/18] HACK: pinctrl: bcm2835: Implement legacy pull for BCM7211
Date: Wed, 17 Jul 2019 23:16:00 +0200	[thread overview]
Message-ID: <1563398164-2679-1-git-send-email-wahrenst@gmx.net> (raw)

This temporay hack is necessary to make the BCM2838/7211 work with the legacy
pull configuration. The better approach is to convert all affected DTS files
to the generic bias control.
