Subject: [PATCH v1 2/3] ARM: tegra: acer-a500: Add aliases for MMC
Date: Sun, 6 Sep 2020 22:00:07 +0300 [thread overview]
Message-ID: <20200906190008.25247-2-digetx@gmail.com> (raw)
In-Reply-To: <20200906190008.25247-1-digetx@gmail.com>
MMC core now supports binding to a specific ID, which is very handy for
embedded devices, like Acer A500, because MMC ID may change depending on
kernel version or configuration which affects MMC driver probe order.
