From e172274ccc55d20536fbdceb6131f38e288541e0 Mon Sep 17 00:00:00 2001 From: Guennadi Liakhovetski Date: Fri, 13 Jun 2008 09:17:31 +0100 Subject: [ARM] 5088/3: pxa2xx: add pxa2xx_set_spi_info to register pxa2xx-spi platform devices Add a function to dynamically allocate and register pxa2xx-spi platform devices, to be used by PXA2xx and PXA3xx based systems. Switch pcm027 and lubbock to use it.
