From mboxrd@z Thu Jan 1 00:00:00 1970 From: Tim Harvey Date: Wed, 2 Apr 2014 23:01:09 -0700 Subject: [U-Boot] [PATCH 09/11] IMX: add additional function for pinmux using an array In-Reply-To: <1396504871-1454-1-git-send-email-tharvey@gateworks.com> References: <1396504871-1454-1-git-send-email-tharvey@gateworks.com> Message-ID: <1396504871-1454-10-git-send-email-tharvey@gateworks.com> List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: u-boot@lists.denx.de Add new function that can take an array of iomux configs, an index, and a stride to allow a multi-dimentional array of pinmux values to be used to define pinmux values per cpu-type. This takes a different approach to previously proposed solutions which used multiple arrays of pad lists. The goal is to eliminate having these multiple arrays such as 'mx6q_uart1_pads' and 'mx6dl_uart1_pads' which are almost identical copies of each other except for the MX6Q/MX6DL prefix on the PAD.
