SDHC (> 4 GB) cards were not tested, yet. Changes since the second RFC: - Addressed all comments that were raised by Pierre Ossman. There were too many to mention them all, so here is the link: http://lkml.org/lkml/2009/2/6/320 Changes since the first RFC: - Use of_iomap() in sdhci-of.c (suggested by Arnd Bergmann). Also added Arnd's Acked-by: line for the sdhci-of patch. - Kconfig help text improved (thanks to Matt Sealey and M. Warner Losh). - In "sdhci: Add quirk to suppress PIO interrupts during DMA transfers" patch: sdhci_init() now clears SDHCI_PIO_DISABLED flag, otherwise we won't disable PIO interrupts after suspend. - New patch: "sdhci: Add type checking for IO memory accessors" -- Anton Vorontsov email: cbouatmailru@gmail.com irc://irc.freenode.net/bd2 From mboxrd@z Thu Jan 1 00:00:00 1970 Return-Path: Received: (majordomo@vger.kernel.org) by vger.kernel.org via listexpand id S1756500AbZBTRcn (ORCPT ); Fri, 20 Feb 2009 12:32:43 -0500 Received: (majordomo@vger.kernel.org) by vger.kernel.org id S1755728AbZBTRcd (ORCPT ); Fri, 20 Feb 2009 12:32:33 -0500 Received: from rtsoft3.corbina.net ([85.21.88.6]:2926 "EHLO buildserver.ru.mvista.com" rhost-flags-OK-FAIL-OK-FAIL) by vger.kernel.org with ESMTP id S1752990AbZBTRcc (ORCPT ); Fri, 20 Feb 2009 12:32:32 -0500 Date: Fri, 20 Feb 2009 20:32:28 +0300 From: Anton Vorontsov To: Pierre Ossman Cc: Ben Dooks , Arnd Bergmann , Kumar Gala , Liu Dave , sdhci-devel@list.drzeus.cx, linux-kernel@vger.kernel.org, linuxppc-dev@ozlabs.org Subject: [PATCH 0/13] FSL eSDHC support Message-ID: <20090220173228.GA5091@oksana.dev.rtsoft.ru> Reply-To: avorontsov@ru.mvista.com MIME-Version: 1.0 Content-Type: text/plain; charset=windows-1251 Content-Disposition: inline User-Agent: Mutt/1.5.18 (2008-05-17) Sender: linux-kernel-owner@vger.kernel.org List-ID: X-Mailing-List: linux-kernel@vger.kernel.org Hi all, Some updates for the eSDHC support: Changes since the third RFC: - Use uninitialized_var() (suggested by Laurent Pinchart); - Fixed a bug in eSDHC SDCLK prescaler calculations because of which we were over-clocking the SDCLK, and that caused CRC errors using some SD cards; - Not a change, but some status: SDHS (50 MHz) cards were tested to NOT work (at least on MPC837x boards) -- this is to be investigated further.
