Subject: [PATCH 2/2] reset: simple: add BCM4908 MISC PCIe reset controller support
Date: Fri, 27 Nov 2020 12:14:42 +0100 [thread overview]
Message-ID: <20201127111442.1096-2-zajec5@gmail.com> (raw)
In-Reply-To: <20201127111442.1096-1-zajec5@gmail.com>
From: Rafał Miłecki <rafal@milecki.pl>
It's a trivial reset controller. One register with bit per PCIe core.
