Subject: [PATCH RFC 09/18] mmc: sdhci-iproc: Add support for emmc2 of the BCM2838
Date: Wed, 17 Jul 2019 21:50:17 +0200
Message-ID: <1563393026-17118-10-git-send-email-wahrenst@gmx.net> (raw)
In-Reply-To: <1563393026-17118-1-git-send-email-wahrenst@gmx.net>
The additional emmc2 interface of the BCM2838 is an improved version
of the old emmc controller, which is able to provide DDR50 mode on the
Raspberry Pi 4. Except 32 bit only register access no other quirks are
known yet.
