[PATCH] ARM: OMAP2+: omap-usb-host: clean up pin mux setup code
Roger Quadros

Mon Apr 22 05:57:53 EDT 2013
The USB host pins are named quite differently between OMAP3 and
OMAP4+ SoCs. To make this managable in code, we create a pin mapping
table (pin_names) that maps pin function to pin name.
This pin mapping table is populated at runtime based on a pin
name template. Templates are provided for OMAP3 and 4 SoCs.
The setup_io_mux() function uses the pin mapping table to
setup the pin mux.
The resulting code is a lot more clean, manageable and scalable.
