This patch series has the support for TWL6030-usb transceiver driver and changes in the musb driver to make it functional with OMAP4430. OMAP4 musb support UTMI and ULPI transceiver interfaces. In UTMI mode, the transceiver functionality is split between the TWL6030 PMIC chip and OMAP4 embedded PHY. The TWL6030 transceiver driver code is under otg folder and internal UTMI PHY specific code changes are defined under mach-omap2 directory and functions are passed through platform_data structure. This patch series is based on V2.6.37-rc4 + [1]+[2] [1] http://www.listware.net/201011/linux-usb/ 65625-patch-resend-v3-usb-musb-do-not-use-dma-for-control-transfers.html [2] Felipe's musb-reorg patch series. http://gitorious.org/usb/usb/commits/musb-hw Tested musb device and host mode functionality with OMAP4430SDP and OMAP3630 ZOOM3. Limitation: In OTG and Host only mode, when the device is connected during boot will not be detected. Need connect the device only after the boot. Or disconnect and connect it back if it connected during boot. Fix for this will be submitted later. Version History: ------------------- Version3 changes: - Rearranged the patches to avoid the git bisect failure. Version 2 changes: - Removed the dependency on the atomic notifier patches from Arnaud. - Fixed review comments from Felipe and Sergei. - Modified the vbus_set function to set timeout when musb is not configured as A device.
