| Message-ID | <rIa4a-8aG-9@gated-at.bofh.it> |
Unlike most Keystone 2 devices, K2G supports pinmuxing of its pins. This patch series enables pinmuxing for Keystone 2 devices. Version 2 changes: Rebased on top of linux-next which includes Keerthy patches.

The pinctrl IP used in some of the Keystone 2 devices differ vs other
TI SoCs. Therefore, create a Keystone specific pinctrl header.
