Subject: [PATCH v2 3/6] ARM: dts: imx6: phytec: Add eeprom pagesize
Date: Thu, 29 Oct 2020 08:03:21 +0100	[thread overview]
Message-ID: <20201029070324.16057-3-s.riedmueller@phytec.de> (raw)
In-Reply-To: <20201029070324.16057-1-s.riedmueller@phytec.de>

Defining the EEPROM pagesize can increase the write speed significantly.
Set it to the pagesize stated in the EEPROM's datasheet for
phyCORE-i.MX 6UL, phyCORE-i.MX 6 and phyFLEX-i.MX 6.
