Subject: [PATCH V3 08/18] ARM: OMAP2+: Convert TUSB to use gpmc_cs_program_settings()
Date: Fri, 15 Mar 2013 10:21:06 -0500 [thread overview]
Message-ID: <1363360876-13617-9-git-send-email-jon-hunter@ti.com> (raw)
In-Reply-To: <1363360876-13617-1-git-send-email-jon-hunter@ti.com>
Convert the OMAP2+ TUSB code to use the gpmc_cs_program_settings()
function for configuring the various GPMC options instead of directly
programming the CONFIG1 register.
