2015-05-07usb: musb: Fix up DMA related macrosTony Lindgren
Pass struct musb to tusb_dma_omap() and is_cppi_enabled(), and add macros for the other DMA controllers. Populate the platform specific quirks with the DMA type and use it during runtime. Note that platform glue layers with no custom DMA code are tagged with MUSB_DMA_INVENTRA which may have a chance of working. Looks like the defconfigs for these use PIO_ONLY, so this should not break existing configs. Signed-off-by: Tony Lindgren <tony@atomide.com> Signed-off-by: Felipe Balbi <balbi@ti.com>

2014-11-03usb: move the OTG state from the USB PHY to the OTG structureAntoine Tenart
Before using the PHY framework instead of the USB PHY one, we need to move the OTG state into another place, since it won't be available when USB PHY isn't used. This patch moves the OTG state into the OTG structure, and makes all the needed modifications in the drivers using the OTG state.

It fixes a bunch of mistakes errors which nobody has triggered before, so I'm not Ccing stable tree. We are finally improving OMAP's VBUS/ID Mailbox usage so that we can introduce our PHY drivers properly. Also, we're adding support for multiple instances of the MUSB IP in the same SoC, as seen on some platforms from TI which have 2 MUSB instances. Other than that, we have some small fixes like not kicking DMA for a zero byte transfer, or properly handling NAK timeout on MUSB's host side, and the enabling of DMA Mode1 for any transfers which are aligned to wMaxPacketSize. All patches have been pending on mailing list for a long time and I don't expect any big surprises with this pull request.

2010-12-10musb: am35x: fix compile error due to control apisAjay Kumar Gupta
commit 4814ced5116e3b73dc4f63eec84999739fc8ed11 (OMAP: control: move plat-omap/control.h to mach-omap2/control.h) moved <plat/control.h> to another location, preventing drivers from accessing it, so we need to pass function pointers from arch code to be able to talk to internal PHY on AM35x.

instead of using musb_platform_suspend_resume, we can use dev_pm_ops and let platform_device core handle when to call musb_core's suspend and glue layer's suspend. Signed-off-by: Felipe Balbi <balbi@ti.com>

2010-12-10usb: musb: move clock handling to glue layerFelipe Balbi
musb core doesn't need to know about platform specific details. So start moving clock handling to platform glue layer and make musb core agnostic about that. Signed-off-by: Felipe Balbi <balbi@ti.com>
2010-12-10usb: musb: pass platform_ops via platform_dataFelipe Balbi
... then we don't need to export any symbols from glue layer to musb_core. Signed-off-by: Felipe Balbi <balbi@ti.com>
