From mboxrd@z Thu Jan 1 00:00:00 1970 From: Jamie Lentin Subject: [PATCH V5 0/4] ARM: Kirkwood: Add support for DNS-320 and DNS-325 using devicetree Date: Wed, 18 Apr 2012 11:06:39 +0100 Message-ID: <1334743603-8488-1-git-send-email-jm@lentin.co.uk> Mime-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit Return-path: List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , Sender: linux-arm-kernel-bounces@lists.infradead.org Errors-To: linux-arm-kernel-bounces+linux-arm-kernel=m.gmane.org@lists.infradead.org To: Arnd Bergmann , Jason , Grant Likely , Andrew Lunn Cc: devicetree-discuss@lists.ozlabs.org, Jamie Lentin , linux-arm-kernel@lists.infradead.org List-Id: devicetree@vger.kernel.org Reworked patch for latest feedback. I'm still basing this on Jason Cooper's tree, given how much time has passed should I be rebasing against something else or is this still fine? One thing I noticed is that with only the first patch applied (which no longer calls kirkwood_nand_init) the device either locks up or serial console dies at "Gating clock of unused units", presumably as CGC_RUNIT isn't set. Is this something known or is it worth further investigation? Thanks again to everyone reviewing. Changes since v4: Convert DNS-325 & DNS-320 to access nand via devicetree * Add initial support patch back in to address following comments ** One MACH_DLINK_KIRKWOOD_DT for all dtb files [Grant Likely, Jason Cooper] ** Drop brain-dead select "select CONFIG_MTD_OF_PARTS" [Grant Likely] ** Don't add NAND support then throw it away immediately after [Grant Likely] * WARN when bank-width is out of range [Andrew Lunn] * Describe purpose of MPP 41, 42 & 49 Changes since v3: Add support for DNS-320 and DNS-325 using devicetree * Remove patches that are already merged * Add documentation on orion_nand devicetree bindings * Convert bank-width to be in bytes to match other properties * Make defaults more explicit Changes since v2: Add support for DNS-320 and DNS-325 using devicetree * Split patches further, separating orion_nand and kirkwood changes * dts renames: "bank-width", not "width". "okay", not "ok" * Separate documentation out into separate patch, add references to partition.txt to all mtd bindings. Changes since v1: Add support for DNS-320 and DNS-325 using devicetree * Rebase against kirkwood_dt_for_3.4, removing premature devicetree ports. * Move additions into a separate board-dnskw.c. It could be separated further into a board-dns320.c and board-dns325.c but it probably isn't worth it. * s/marvell,/mrvl,/g * Include an example dtb partition in documentation * Copy structure of serial nodes to allow common options for NAND to be set in kirkwood.dtsi * Simplifications in orion-nand.c Jamie Lentin (4): ARM: kirkwood: Basic support for DNS-320 and DNS-325 mtd: Add orion_nand devicetree bindings kirkwood: Allow nand to be configured via. devicetree ARM: kirkwood: Define DNS-320/DNS-325 NAND in fdt .../devicetree/bindings/mtd/orion-nand.txt | 50 ++++ arch/arm/boot/dts/kirkwood-dns320.dts | 64 +++++ arch/arm/boot/dts/kirkwood-dns325.dts | 59 +++++ arch/arm/boot/dts/kirkwood.dtsi | 15 +- arch/arm/mach-kirkwood/Kconfig | 8 + arch/arm/mach-kirkwood/Makefile | 1 + arch/arm/mach-kirkwood/Makefile.boot | 2 + arch/arm/mach-kirkwood/board-dnskw.c | 275 ++++++++++++++++++++ arch/arm/mach-kirkwood/board-dt.c | 5 + arch/arm/mach-kirkwood/common.c | 12 + arch/arm/mach-kirkwood/common.h | 6 + drivers/mtd/nand/orion_nand.c | 45 +++- 12 files changed, 539 insertions(+), 3 deletions(-) create mode 100644 Documentation/devicetree/bindings/mtd/orion-nand.txt create mode 100644 arch/arm/boot/dts/kirkwood-dns320.dts create mode 100644 arch/arm/boot/dts/kirkwood-dns325.dts create mode 100644 arch/arm/mach-kirkwood/board-dnskw.c -- 1.7.9.1
