* usb: musb: omap: write directly to mailbox instead of using phyKishon Vijay Abraham I2012-09-112-7/+54
| | | | | | | | | | | | | The glue layer should directly write to mailbox register (present in control module) instead of calling phy layer to write to mailbox register. Writing to mailbox register notifies the core of events like device connect/disconnect. Currently writing to control module register is taken care in this driver which will be removed once the control module driver is in place.

* usb: musb: omap2430: don't loop indefinitely in interrupt.NeilBrown2012-08-141-1/+5
| | | | | | | | | | | | | | When called during resume_irqs, omap2430_musb_set_vbus() is run with interrupts disabled, In that case 'jiffies' never changes so the loop can loop forever. So impose a maximum loop count and add an 'mdelay' to ensure we wait a reasonable amount of time for bit to be cleared. This fixes a hang on resume.

This patch sets the NAK timeout interval for such QHs, and when a timeout triggers the next QH will be scheduled.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This provides a new API allows different OLPC architectures to override the EC driver. x86 and ARM OLPC machines use completely different EC backends. The olpc_ec_cmd is synchronous, and waits for the workqueue to send the command to the EC. Multiple callers can run olpc_ec_cmd() at once, and they will by serialized and sleep while only one executes on the EC at a time. We don't provide an unregister function, as that doesn't make sense within the context of OLPC machines - there's only ever 1 EC, it's critical to functionality, and it certainly not hotpluggable.

Further lack of checking any sort of errors from gpio_request() resulted in boot time warnings, tripping on the FLAG_REQUESTED test-and-set in gpio_ensure_requested(). As it turns out there's no particular need to bother with the two-stage registration, as the platform bus is already available at the point that we have to start caring. As such, it's easiest to simply fold these together in to a single init path, the ordering of which is ensured through the platform's mux registration, as usual. Reported-by: Rafael J.
