Subject: [RESEND PATCH v2 2/2] arm64: dts: ti: k3-am64-evm/sk: Add OSPI flash DT node
Date: Thu, 18 Mar 2021 17:07:57 +0530 [thread overview]
Message-ID: <20210318113757.21012-2-vigneshr@ti.com> (raw)
In-Reply-To: <20210318113757.21012-1-vigneshr@ti.com>
Both AM64 EVM and SK have a 512Mb S28HS512T Octal SPI NOR flash.
Add DT node for the same.

Rebase onto latest -next
There is a warning related to dtbs_check which is because
spi-cadence-quadspi.txt is not converted to YAML.
