* usb: musb: USB_TI_CPPI41_DMA requires dmaengine supportArnd Bergmann2015-11-181-1/+1
| | | | | | | | | | | | | | | | The CPPI-4.1 driver selects TI_CPPI41, which is a dmaengine driver and that may not be available when CONFIG_DMADEVICES is not set: warning: (USB_TI_CPPI41_DMA) selects TI_CPPI41 which has unmet direct dependencies (DMADEVICES && ARCH_OMAP) This adds an extra dependency to avoid generating warnings in randconfig builds. Ideally we'd remove the 'select' statement, but that has the potential to break defconfig files.

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.

| | | | | | | | | | | | | | | | | | A recent bug fix I did that was marked for stable backports introduced a slightly wrong dependency on CONFIG_OMAP_CONTROL_PHY. I was missing the fact that the PHY driver already stubs out the omap_control_usb_set_mode, and we only need to add a dependency to prevent the musb-omap2430 driver from being built-in when the phy driver is a loadable module, but we should not prevent it from being built altogether when the phy driver is disabled.

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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

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.

We have also some more conversions to the new udc_start/udc_stop which makes us closer from dropping the old interfaces. USB_GADGET_DUALSPEED and USB_GADGET_SUPERSPEED are finally gone, thanks to Michal for his awesome work. Other than that, we have the usual set of miscellaneous changes and cleanups involving improvements to debug messages, removal of duplicated includes, moving dereference after NULL test, making renesas_hsbhs' irq handler Shared, unused code being dropped, prevention of sleep-inside-spinlock bugs and a race condition fix on udc-core.
| * | usb: gadget: get rid of USB_GADGET_{DUAL,SUPER}SPEEDMichal Nazarewicz2012-08-311-1/+0
| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This commit removes USB_GADGET_DUALSPEED and USB_GADGET_SUPERSPEED Kconfig options. Since now kernel allows many UDC drivers to be compiled, those options may turn to no longer be valid. For instance, if someone decides to build UDC that supports super speed and UDC that supports high speed only, the latter will be "assumed" to support super speed since USB_GADGET_SUPERSPEED will be selected by the former. The test of whether CONFIG_USB_GADGET_*SPEED was defined was just an optimisation which removed otherwise dead code (ie. if UDC is not dual speed, there is no need to handle cases that can happen if speed is high). This commit removes those checks. Signed-off-by: Michal Nazarewicz <mina86@mina86.com> Signed-off-by: Felipe Balbi <balbi@ti.com>

* usb: musb: use a Kconfig choice to pick the right DMA methodArnd Bergmann2011-12-121-23/+34
| | | | | | | | | | | | | | | | | | 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.
