Subject: [PATCH v2 2/2] arm64: dts: ti: k3-j7200-som-p0: Add HyperFlash node
Date: Wed, 23 Sep 2020 22:01:50 +0530 [thread overview]
Message-ID: <20200923163150.16973-3-vigneshr@ti.com> (raw)
In-Reply-To: <20200923163150.16973-1-vigneshr@ti.com>
J7200 SoM has a HyperFlash connected to HyperBus memory controller. But
HyperBus is muxed with OSPI, therefore keep HyperBus node disabled.
Bootloader will detect the mux and enable the node as required.
