Subject: [U-Boot] [PATCH 0/4] Add support for TI PCF8575 I2C GPIO expander
Date: Mon, 25 Jul 2016 18:40:19 +0530 [thread overview]
Message-ID: <20160725131023.30656-1-vigneshr@ti.com> (raw)
This series adds support for TI's PCF8575 I2C GPIO expander[1] based on
Linux Kernel driver for the same. Also adds support for ethernet to use
new PCF8575 driver to select appropriate cpsw slaves on dra72.
Depends on I2C DM support [2]
Tested on DRA72 EVM.
