[U-Boot] [PATCH 0/4] Add support for TI PCF8575 I2C GPIO expander

[Vignesh R]

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.
