Subject: [PATCH 26/36] ARM: OMAP2+: gpmc-smc91x: Get rid of retime() from omap_smc91x_platform_data
Date: Wed, 11 Jun 2014 11:56:31 +0300 [thread overview]
Message-ID: <1402477001-31132-27-git-send-email-rogerq@ti.com> (raw)
In-Reply-To: <1402477001-31132-1-git-send-email-rogerq@ti.com>
The retime() function is not provided by board files so get rid of
it from omap_smc91x_platform_data().
Instead change it to smc91c96_get_device_timing() to get the device
timings.
