Linus Walleij eeb690bceb pinctrl: gemini: Fix missing pad descriptions
A pretty clever static checker found a bug in my patch: I added more
bits to a bitmask but didn't extend the array indexed to the same
bitmask.

Linus Walleij 756a024f39 pinctrl: gemini: Fix GMAC groups
The GMII groups need to be split across GMAC0 and GMAC1 since
GMAC0 is always available but GMAC1 masks GPIO2 lines 0-7
so we might want just one interface out.

Linus Walleij 60ad481f74 pinctrl: gemini: Implement clock skew/delay config
This enabled pin config on the Gemini driver and implements
pin skew/delay so that the ethernet pins clocking can be
properly configured.

Linus Walleij 1c5b7f3c34 pinctrl: gemini: Use generic DT parser
We can just use the generic Device Tree parser code
in this driver and save some code.

Linus Walleij 89aab2d6a7 pinctrl: gemini: Add missing functions
Some two functions were missing from the Gemini pin control
driver. Noticed when trying to use ethernet. Fix it up by
adding them.

Linus Walleij 06351d133d pinctrl: add a Gemini SoC pin controller
This adds a pin control (only multiplexing) driver for the Gemini
SoC so we can sort out this complex platform in an orderly manner.

This driver will detect the chip/package version as SL3512 or SL3516
(also known as CS3512 and CS3516 etc) and register the apropriate
pin set.
