Subject: [PATCH v4 1/4] dt-bindings: memory-controllers: ti,gpmc: Add compatible for AM64
Date: Tue, 21 Dec 2021 15:17:54 +0200	[thread overview]
Message-ID: <20211221131757.2030-2-rogerq@kernel.org> (raw)
In-Reply-To: <20211221131757.2030-1-rogerq@kernel.org>

AM64 SoC contains the GPMC module. Add compatible for it.

Newer SoCs don't necessarily map GPMC data region at the same place
as legacy SoCs. Add reg-names "data", to provide this information to
the device driver.
