Tom Rini a591af1123 include/spl_gpio.h: Audit include list 
This file does not need <asm/gpio.h> so remove it. This file does
however need <linux/types.h> so add that in. This also shows that
arch/arm/mach-rockchip/rk3399/rk3399.c and board/lg/star/star.c were
indirectly getting <asm/gpio.h> from here, so add <asm/gpio.h> to them.

Svyatoslav Ryhel 2ff444d07d drivers: tegra_gpio: add early SPL functions 
In some cases access to GPIOs is needed so early that DM
is not ready even nearly. These functions are exactly for
this case.

Heinrich Schuchardt 185f812c41 doc: replace @return by Return: 
Sphinx expects Return: and not @return to indicate a return value.

find . -name '*.c' -exec \
sed -i 's/^\(\s\)\*\(\s*\)@return\(\s\)/\1*\2Return:\3/' {} \;

find . -name '*.h' -exec \
sed -i 's/^\(\s\)\*\(\s*\)@return\(\s\)/\1*\2Return:\3/' {} \;

Simon Glass 5c01d1c0d0 gpio: Add a simple GPIO API for SPL 
In space-constrained environments or before driver model is available, it
is sometimes necessary to set GPIO values. Add an SPL API for this, to
allow early board code to change GPIOs. The caller must provide the
register address, so that the drivers can be fairly generic.

This API can be implemented by GPIO drivers, behind a suitable guard,
like #ifdef CONFIG_SPL_BUILD.
