arm:omap:am33xx: Register HSMMC Platform on AM335x EVM
authorHebbar, Gururaja <gururaja.hebbar@ti.com>
Tue, 4 Oct 2011 18:19:18 +0000 (23:49 +0530)
committerVaibhav Hiremath <hvaibhav@ti.com>
Mon, 23 Jan 2012 19:14:26 +0000 (00:44 +0530)
This patch adds the hardware info like pin-mux, platform data and
registers the MMC module. AM335x SOC supports 3 HS-MMC instances.
However only 2 HS-MMC (MMC0, 1) instances are supported on EVM.
