From mboxrd@z Thu Jan 1 00:00:00 1970 From: Kishon Vijay Abraham I Subject: [PATCH v7 0/7] omap: musb: Add device tree support Date: Mon, 6 Aug 2012 18:37:53 +0530 Message-ID: <1344258480-4304-1-git-send-email-kishon@ti.com> Mime-Version: 1.0 Content-Type: text/plain Return-path: Sender: linux-kernel-owner@vger.kernel.org To: grant.likely@secretlab.ca, rob.herring@calxeda.com, rob@landley.net, linux@arm.linux.org.uk, gregkh@linuxfoundation.org, b-cousson@ti.com, rnayak@ti.com, tony@atomide.com, devicetree-discuss@lists.ozlabs.org, linux-doc@vger.kernel.org, linux-kernel@vger.kernel.org, linux-arm-kernel@lists.infradead.org, linux-omap@vger.kernel.org, linux-usb@vger.kernel.org Cc: Kishon Vijay Abraham I List-Id: devicetree@vger.kernel.org This patch series adds device tree support for MUSB and device tree support for all the related modules to get MUSB working in OMAP platform. A new omap-usb2 phy driver has been added (with only dt suppport) to perform phy configurations. Previously this configuration was performed by twl6030, using pdata function pointers. With the addition of omap-usb2 to perform phy configurations, twl6030 is made as a comparator driver to detect VBUS and ID events and notify it to the glue layer. musb core is _NOT_ yet converted to support device tree support as it would need lot of driver re-design because of its enormous use of function pointers. That will be in _TO DO_ list. Changes from v6: * Removed the dt data part of the patch series. It'll be sent as a separate series. * Replaced arch initcall in omap-usb2 phy driver with a module platform driver. Dependent drivers should use -EPROBE_DEFER. Changes from v5: minor cleanups like checking for return value in get_sync and few changes in the documentation has been done. Changes from v4: duplicate getting of 'mode' property is removed in omap-musb glue. Changes from v3: remove the address in the node name of usb_otg_hs since the usb_otg_hs node doesn't have a reg property. Thanks Ajay Gupta for finding this. Changes from v2: Fixed Sergei's comment to remove *0x* prefix in usb2phy@0x4a0ad080 Changes from v1: * Fixed Rajendra Nayak comments (regulator naming, compatible naming of musb and other minor cleanups.) * It's agreed to have ocp2scp in drivers/bus and usb2 phy is a child of ocp2scp, the documentation is updated accordingly. Changes from RFC: Removed the dependency on [RFC PATCH 00/11] OMAP System Control Module. Writing to control module register is now handled in otg driver itself. Once the system control module driver get upstreamed, I'll send a patch to make use of API's in control module driver to write to control module register. This series was developed on git://git.kernel.org/pub/scm/linux/kernel/git/balbi/usb.git xceiv This patch series depends on [PATCH v3 0/2] omap: add ocp2scp as a bus driver Performed MUSB device mode testing on OMAP4 panda, OMAP4 SDP and OMAP3 beagle.
