usb: musb: add tracepoints support for debugging

2016-07-16T23:23:57+00:00

To avoid printk() overhead while debugging, this patch implements the foundation of tracepoints logging for musb driver to make debug easier. Signed-off-by: Bin Liu Signed-off-by: Greg Kroah-Hartman

usb: musb: sunxi: Add support for the Allwinner sunxi musb controller

2015-07-29T14:59:20+00:00

This is based on initial code to get the Allwinner sunxi musb controller supported by Chen-Yu Tsai and Roman Byshko. This adds support for the Allwinner sunxi musb controller in both host only and otg mode. Peripheral only mode is not supported, as no boards use that. This has been tested on a cubietruck (A20 SoC) and an UTOO P66 tablet (A13 SoC) with a variety of devices in host mode and with the g_serial gadget driver in peripheral mode, plugging otg / host cables in/out a lot of times in all possible imaginable plug orders.

usb: musb: add support for JZ4740 usb device controller

2013-12-20T15:53:24+00:00

Add support for Ingenic JZ4740 USB Device Controller through a specific musb glue layer. JZ4740 UDC not being OTG compatible and missing some hardware registers, this musb glue layer is written from scratch to be used in gadget mode only and take silicon design specifics into account.

usb: musb dma: add cppi41 dma driver

2013-08-09T14:40:16+00:00

This driver is currently used by musb' cppi41 couter part. I may merge both dma engine user of musb at some point but not just yet. The driver seems to work in RX/TX mode in host mode, tested on mass storage. I increaed the size of the TX / RX transfers and waited for the core code to cancel a transfers and it seems to recover. v2..3: - use mall transfers on RX side and check data toggle. - use rndis mode on tx side so we haveon interrupt for 4096 transfers. - remove custom "transferred" hack and use dmaengine_tx_status() to compute the total amount of data that has been transferred. - cancel transfers and reclaim descriptors v1..v2: - RX path added - dma mode 0 & 1 is working - device tree nodes re-created.

usb: musb: dsps: use proper child nodes

2013-08-09T14:35:44+00:00

This moves the two instances from the big node into two child nodes. The glue layer ontop does almost nothing. There is one devices containing the control module for USB (2) phy, (2) usb and later the dma engine. The usb device is the "glue device" which contains the musb device as a child. This is what we do ever since. The new file musb_am335x is just here to prob the new bus and populate child devices. There are a lot of changes to the dsps file as a result of the changes: - musb_core_offset This is gone. The device tree provides memory ressources information for the device there is no need to "fix" things - instances This is gone as well. If we have two instances then we have have two child enabled nodes in the device tree. For instance the SoC in beagle bone has two USB instances but only one has been wired up so there is no need to load and init the second instance since it won't be used. - dsps_glue is now per glue device In the past there was one of this structs but with an array of two and each instance accessed its variable depending on the platform device id. - no unneeded copy of structs I do not know why struct dsps_musb_wrapper is copied but it is not necessary. The same goes for musb_hdrc_platform_data which allocated on demand and then again by platform_device_add_data(). One copy is enough.

usb: musb: add Kconfig options for HOST, GAGDET or DUAL_ROLE modes

2013-05-28T16:22:23+00:00

This makes building the actual object files optional to the selected mode, which saves users who know which kind of USB mode support they need some binary size. Unimplemented functions are stubbed out with static inline functions. Signed-off-by: Daniel Mack Acked-by: Peter Korsgaard Signed-off-by: Felipe Balbi

usb: musb: Add support for ti81xx platform

2012-05-04T10:59:34+00:00

TI81XX platform has two musb interfaces and uses CPPI4.1 DMA engine. It has builtin USB PHYs as AM35x. The current set of patches adds support for one instance and only in PIO mode.

usb: musb: use a Kconfig choice to pick the right DMA method

2011-12-12T09:51:41+00:00

The logic to allow only one DMA driver in MUSB is currently flawed, because it also allows picking no DMA driver at all and also not selecting PIO mode. Using a choice statement makes this foolproof for now and also simplifies the Makefile. Unfortunately, we will have to revisit this when we start supporting multiple ARM platforms in a single kernel binary, because at that point we will actually need to select multiple DMA drivers and pick the right one at run-time.

usb: musb: drop a gigantic amount of ifdeferry

2011-07-01T21:31:10+00:00

the MUSB IP is always OTG, so there's no point in adding so many ifdefs on the code. Drop those and always compile the driver for OTG support. This also allows us to drop the useless "driver mode" choice. For doing that, we need to make musb depend on both Host and Peripheral side.
