From 55429a0323c8b39618b0005a7b8e496c5f8da997 Mon Sep 17 00:00:00 2001 From: Marek Vasut Date: Mon, 5 Apr 2010 02:28:14 +0200 Subject: PXA: PXAMMC: Drop different delays for PXA27X In case the delays were set to 10000, the MMC card on PXA27X boards (and PXA3xx boards) didn't initialize on first try. Increasing the delays and leaving just those for PXA25x and 26x (that is 200000) fixes this problem.

This patch only enables MMC1 though, MMC2 and PXA31x MMC3 will need further patch to be operational.
