* usb/gadget: fix poller NPE in early pollingRobert Jarzmik2012-01-231-9/+10
| | | | | | | | | | | | | The timings of the poller calling have changed, digging out a latent bug in pxa27x udc controller. The polling routine is called before the probe function is called, and the driver internal are not initialized at that time. This triggers a NULL pointer exception. Fix it by moving poller registration after driver probe. Signed-off-by: Robert Jarzmik <robert.jarzmik@free.fr> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

* serial gadget: enable/disable on requestEric Bénard2012-01-044-19/+60
| | | | | | | | | | | | | | - add a usbserial command to enable/disable the serial gadget - allow dfu and usbserial to cohexist in the same barebox - add a timeout in u_serial so that we don't get locked if the user enable usbserial from a UART console but doesn't consume the data on the usbserial port created on the PC - remove debug or verbose printf - tested on i.MX25 & i.MX35 & usb-a926x Signed-off-by: Eric Bénard <eric@eukrea.com> Tested-by: Jean-Christophe PLAGNIOL-VILLARD <plagnioj@jcrosoft.com> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* dfu: fill bwPollTimeout and better handle detachEric Bénard2012-01-041-1/+8
| | | | | | | | | | | | | | | | | - bwPollTimeout is set to 10 ms, from the DFU spec, this is the minimum time, in milliseconds, that the host should wait before sending a subsequent DFU_GETSTATUS request. Without this, I get 25 seconds value and dfu-util waits twice 25s during download - when in IDLE and receiving DETACH, first return 0 to make dfu-util happy, then use a dfudetach variable to exit dfu (without an USB reset as per the comment on line 425) and return to runtime mode. - tested on i.MX25 & i.MX35 & usb-a926x Signed-off-by: Eric Bénard <eric@eukrea.com> Tested-by: Jean-Christophe PLAGNIOL-VILLARD <plagnioj@jcrosoft.com> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* fsl_udc: update and fixEric Bénard2012-01-041-9/+36
| | | | | | | | | | | - this patch sync fsl_udc.c with linux's driver, - add a poller on usb_gadget_poll to get serial gadget working, - return -EIO in usb_gadget_poll when udc is stopped (do detect cable disonnection) - tested on i.MX25 & i.MX35 Signed-off-by: Eric Bénard <eric@eukrea.com> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

* usb/gadget: make serial gadget resistant to cable unplugRobert Jarzmik2011-12-051-6/+18
| | | | | | | | | | | | | | As USB can have its cable plugged out anytime, make the serial gadget reliable in case of unplugging : - unregister the gadget_serial provided console - don't stay forever in the read loop if connection was cut This behaviour relies on correct implementation of usb_gadget_poll(), which should return an error if the USB cable was removed.

* usb/gadget: add USB serial connect and disconnectRobert Jarzmik2011-12-051-1/+4
| | | | | | | | | | | | | The serial gadget can only work if the serial function is properly connected on USB trigger (ie. on SET_CONFIGURATION or SET_INTERFACE USB message triggering set_alt() in composite.c). Make this connection and handle also the disconnection in f_serial. Signed-off-by: Robert Jarzmik <robert.jarzmik@free.fr> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* usb/gadget: use generic usb_gadget_poll() in u_serialRobert Jarzmik2011-12-051-3/+2
| | | | | | | | | Use the generic gadget polling function instead of the specific fsl function. This is a fix from a leftover in gadget development. Signed-off-by: Robert Jarzmik <robert.jarzmik@free.fr> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

* Fix error handling with malloc, memalign etc. Introduce xmemalign().Krzysztof Halasa2011-01-073-11/+2
| | | | | | | | | | | | | | The idea is to panic() when there is no memory available for normal operation. Exception: code which can consume arbitrary amount of RAM (example: files allocated in ramfs) must report error instead of panic(). This patch also fixes code which didn't check for NULL from malloc() etc. Usage: malloc(), memalign() return NULL when out of RAM. xmalloc(), xmemalign() always return non-NULL or panic().
