* usb: musb: core: Convert the musb_platform_reset to have a return value.George Cherian2014-07-161-4/+6
| | | | | | | | | | | | | Currently musb_platform_reset() is only used by dsps. In case of BABBLE interrupt for other platforms the musb_platform_reset() is a NOP. In such situations no need to re-initialize the endpoints. Also in the latest silicon revision of AM335x, we do have a babble recovery mechanism without resetting the IP block. In preperation to add that support its better to have a rest_done return for musb_platform_reset().

* usb: musb: core: Convert babble recover work to delayed workGeorge Cherian2014-07-161-1/+1
| | | | | | | | | | | | | | | During babble condition both first disconnect of devices are initiated. Make sure MUSB controller is reset and re-initialized after all disconnects. To acheive this schedule a delayed work for babble recovery. While at that convert udelay to usleep_range.

* usb: musb: add a work_struct to recover from babble errorsDaniel Mack2014-04-211-0/+1
| | | | | | | | | | | | Handle BABBLE interrupt error conditions from a work struct handler. This indirection is necessary as we can't be certain that the phy functions don't sleep.

* usb: musb: add reset hook to platform opsDaniel Mack2014-04-211-0/+7

* usb: musb: finish suspend/reset work independently from musb_hub_control()Daniel Mack2013-12-191-0/+3
| | | | | | | | | | | | | | | | | | | | | Currently, resume and reset is completed when the USB core calls back the root hub, asking for the port's state. This results in unpredictable timing of state assertion, which in turn renders some USB devices unusable after resume. Fix this by moving the logic to end the reset and suspend state out of musb_hub_control() into separate functions called from delayed workers. GetPortStatus only reports the current state now, without taking any real action. The rh_timeout variable is kept in order to define a minimum time gap between reset and resume only. FWIW, in my case, a Verbatim "STORE N GO" mass storage device won't resume cleanly without this patch. Signed-off-by: Daniel Mack <zonque@gmail.com> Signed-off-by: Felipe Balbi <balbi@ti.com>

| * usb: musb: start musb on the udc side, tooSebastian Andrzej Siewior2013-10-111-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I have am335x-evm with one port running in OTG mode. Since commit fe4cb09 ("usb: musb: gadget: remove hcd initialization") the loaded gadget does non pop up on the host. All I see is |usb 4-5: new high-speed USB device number 52 using ehci-pci |usb 4-5: device descriptor read/64, error -110 Since a later commit 2cc65fe ("usb: musb: add musb_host_setup() and musb_host_cleanup()) the gadget shows up on the host again but only in OTG mode (because we have the host init code running). It does not work in device only mode. If running in OTG mode and the gadget is removed and added back (rmmod followed by modprobe of a gadget) then the same error is pops up on the host side. This patch ensures that the gadget side also executes musb_start() which puts the chip in "connect accept" mode. With this change the device works in OTG & device mode and the gadget can be added & removed multiple times. A device (if musb is in OTG mode acting as a host) is only recognized if it is attached during module load (musb_hdrc module). After the device unplugged and plugged again the host does not recognize it. We get a buch of errors if musb running in OTG mode, attached to a host and no gadget is loaded. Bah. This is one step forward. Host & device only mode should work. I will look at OTG later. I looked at this before commit fe4cb09 and OTG wasn't working there perfectly so I am not sure that it is a regression :) Cc: <stable@vger.kernel.org> # v3.11 Cc: Daniel Mack <zonque@gmail.com> Cc: Peter Korsgaard <jacmet@sunsite.dk> Signed-off-by: Sebastian Andrzej Siewior <bigeasy@linutronix.de> Signed-off-by: Felipe Balbi <balbi@ti.com>
* | usb: musb: omap2430: use the new generic PHY frameworkKishon Vijay Abraham I2013-09-281-0/+2
|/ | | | | | | | | | | | | | | Use the generic PHY framework API to get the PHY. The usb_phy_set_resume and usb_phy_set_suspend is replaced with power_on and power_off to align with the new PHY framework. musb->xceiv can't be removed as of now because musb core uses xceiv.state and xceiv.otg. Once there is a separate state machine to handle otg, these can be moved out of xceiv and then we can start using the generic PHY framework.

* usb: musb: factor out hcd initalizationDaniel Mack2013-05-281-0/+1
| | | | | | | | | | | | | | | | The musb struct is currently allocated along with the hcd, which makes it difficult to build a driver that only acts as gadget device. Fix this by allocating musb directly, and keep the hcd around as a pointer in the musb struct. struct hc_driver musb_hc_driver can now also be static to musb_host.c, and the macro musb_to_hcd() is just a pointer dereferencer for now, and will be eliminated later.

| | | | | | | | | | | | | | | | | | | | | | | | | | DMA mode 1 data corruption anomaly on Blackfin systems. This issue is specific to the Blackfin silicon as the bug appears to be related to the connection of the musb ip to the bus/dma fabric. Data corruption when using USB DMA mode 1. (Issue manager 17-01-0105) DMA mode 1 allows large size transfers to generate a single interrupt at the end of the entire transfer. The transfer is split up in packets of length specified in the Maximum Packet Size field for that endpoint. If the transfer size is not an integer multiple of the Maximum Packet Size, a short packet will be present at the end of the transfer. Under certain conditions this packet may be corrupted in the USB FIFO. Workaround: Use DMA mode 1 to transfer (n* Maximum Packet Size) and schedule DMA mode 0 to transfer the short packet. As an example if your transfer size is 33168 bytes and Maximum Packet Size equals 512, schedule [33168 - (33168 mod 512)] in DMA mode 1 and the remainder (33168 mod 512) in DMA mode 0.

* usb: musb: Adding musb support for OMAP4430Hema HK2010-12-101-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | OMAP4430 supports UTMI and ULPI types of transceiver interface. In UTMI mode: The PHY is embedded within OMAP4430. The transceiver functionality is split between the twl6030 PMIC chip and OMAP4430. The VBUS, ID pin sensing and OTG SRP generation part is integrated in TWL6030 and UTMI PHY functionality is embedded within the OMAP4430. There is no direct interactions between the MUSB controller and TWL6030 chip to communicate the session-valid, session-end and ID-GND events. It has to be done through a software by setting/resetting bits in one of the control module register of OMAP4430 which in turn toggles the appropriate signals to MUSB controller. musb driver is register for blocking notifications from the transceiver driver to get the event notifications for connect/disconnect and ID-GND. Based on these events call the transceiver init/shutdown function to configure the transceiver to toggle the VBUS valid, session end and ID_GND signals to musb and power on/off the internal PHY. For ID_GND event notifications, toggle the ID_GND signal and then wait for musb to be configured as "A" device, and then call the transceiver function to set the VBUS. In OTG mode and musb as a host, When the Micro A connector used, VBUS is turned on and session bit set. When the device is connected, enumeration goes through. When the device disconnected from the other end of the connector(ID is still grounded), link will detect the disconnect and end the session. When the device is connected back, there are no events generated in the TWL6030-usb, and link is already down. So the device is not detected. Removed the session bit disable code which will recognize the connect of the device. Limitation: In OTG host mode, if device is connected during boot, it does not get detected. If disconnect and connect it back or connect after boot only it works. Fix for this, I will submit seperate patch later.
