Davinci: gpio - register layout invariant inlines

Browse source

This patch renders the inlined gpio accessors in gpio.h independent of the
underlying controller's register layout.  This is done by including three new
fields in davinci_gpio_controller to hold the addresses of the set, clear, and
in data registers.

Other changes:

1. davinci_gpio_regs structure definition moved to gpio.c.  This structure is
no longer common across all davinci socs (davinci_gpio_controller is).

2. controller base address calculation code (gpio2controller()) moved to
gpio.c as this was no longer necessary for the inline implementation.

3. modified inline range checks to use davinci_soc_info.gpio_num instead of
DAVINCI_N_GPIO.
