Subject: [PATCH v2 1/1] drivers: mtd: spi-nor: update read capabilities for w25q64 and s25fl064k
Date:   Fri, 29 May 2020 12:46:55 +0530
Message-Id: <20200529071655.739-1-rayagonda.kokatanur@broadcom.com>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

Both w25q64 and s25fl064k nor flash support QUAD and DUAL read
command, hence update the same in flash_info table.

This is tested on Broadcom Stingray SoC (bcm958742t).
