From c54dd442b489116234ec27a1d3575f274060b68f Mon Sep 17 00:00:00 2001 From: Liu Gang Date: Wed, 23 Mar 2016 17:47:20 +0800 Subject: [PATCH] ARM: dts: ls1021a: Add gpio support for ls1021a platform Add gpio nodes for ls1021a platform dts file. The gpio IP block of the ls1021a can be supported by the code drivers/gpio/gpio-mpc8xxx.c. The compatible "fsl,qoriq-gpio" is used by gpio driver: drivers/gpio/gpio-mpc8xxx.c to implement general gpio functionalities. The chip-specific compatible "fsl,ls1021a-gpio" may be used to fix potential gpio IP block errata or other chip-specific gpio issues.
