Subject: [U-Boot] [PATCH 2/4] ARM: dra7xx_evm: Enable support for TI PCF8575
Date: Mon, 25 Jul 2016 18:40:21 +0530 [thread overview]
Message-ID: <20160725131023.30656-3-vigneshr@ti.com> (raw)
In-Reply-To: <20160725131023.30656-1-vigneshr@ti.com>
On DRA7, pcf chip present at address 0x21 on i2c1, is used to
switch between cpsw slave0 and slave1. Hence, enable PCF
driver for the same.
