Subject: [PATCH 2/9] spi: cadence_qspi: Add support for Versal NET platform
Date: Fri, 16 Sep 2022 10:53:13 +0200	[thread overview]
Message-ID: <00cfd4f55365b682440d57fcd46789b5844b8e6b.1663318393.git.michal.simek@amd.com> (raw)
In-Reply-To: <cover.1663318393.git.michal.simek@amd.com>

Trivial changes to support cadence ospi driver for Versal NET platform.
Also avoid ospi flash reset for now.
