From mboxrd@z Thu Jan 1 00:00:00 1970 From: Gang.Liu@nxp.com (Liu Gang) Date: Wed, 23 Mar 2016 17:47:20 +0800 Subject: [PATCH v2] gpio/ls1021a: Add gpio support for ls1021a platform In-Reply-To: <1458726442-1851-1-git-send-email-Gang.Liu@nxp.com> References: <1458726442-1851-1-git-send-email-Gang.Liu@nxp.com> Message-ID: <1458726442-1851-2-git-send-email-Gang.Liu@nxp.com> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org 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.
