Subject: [PATCH v3 1/4] dt-bindings: memory-controllers: ti,gpmc: Add compatible for AM64
Date: Fri, 17 Dec 2021 12:29:42 +0200 [thread overview]
Message-ID: <20211217102945.17432-2-rogerq@kernel.org> (raw)
In-Reply-To: <20211217102945.17432-1-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.
