Subject: [PATCH] ARM: ux500: 8500: update I2C sleep states pinctrl

From: Patrice Chotard <patrice.chotard@...ricsson.com>

This defines the proper sleep states for all the I2C pins of
the MOP500 DB8500 ASIC setting.

Requesting ARM SoC ACKs to take this through pinctrl for
ease-of-merge going forward, as dependecies are in there.
