CONFIG_ARCH_OMAP34XX is now CONFIG_ARCH_OMAP3. But since drivers/usb/musb/omap2430.c use CONFIG_PM for these registers and functions, do the same for the header. Otherwise we get the following for most omap3 defconfigs: drivers/usb/musb/omap2430.c:261: error: expected identifier or '(' before 'do' drivers/usb/musb/omap2430.c:261: error: expected identifier or '(' before 'while' drivers/usb/musb/omap2430.c:268: error: expected identifier or '(' before 'do' drivers/usb/musb/omap2430.c:268: error: expected identifier or '(' before 'while' Signed-off-by: NTony Lindgren <tony@atomide.com> Signed-off-by: NFelipe Balbi <felipe.balbi@nokia.com> Signed-off-by: NGreg Kroah-Hartman <gregkh@suse.de>

All current Blackfin parts are using RTL v1.9, but they don't expose the hardware registers to probe this dynamically. So hardcode the version to v1.9 for now. Need to move the local hwvers related defines higher up in the header so that sub-musb headers may utilize them.

Adding support for MUSB register save and restore during system suspend and resume. Changes: - Added musb_save/restore_context() functions - Added platform specific musb_platform_save/restore_context() to handle platform specific jobs. - Maintaining BlackFin compatibility by adding read/write functions for registers which are not available in BlackFin Tested system suspend and resume on OMAP3EVM board.

MUSB: save hardware revision at init This can be used later to flag workarounds for issues affecting particular revisions. Saving this at init avoids having to read the HWVERS register multiple times in code. While at it, use macros to extract the version information instead of using hardcoded values.

Tested on OMAP3 host side with Creative (Live! Cam Optia) USB camera which uses high bandwidth isochronous IN endpoints. FIFO mode 4 is updated to provide the needed 4K endpoint buffer without breaking the g_nokia composite gadget configuration.

Minor cleanup of OTG timer handling: * unify decls for OTG time constants, in the core header * set up and use that timer in a more normal way * move to the driver struct, so it's usable outside core And tighten use and setup of T(a_wait_bcon) so that if it's used, it's always valid. (If that timer expires, the A-device will stop powering VBUS. For non-OTG systems, that will be a surprise.) No behavioral changes, other than more consistency when applying that core HNP timeout.

Let the otg_transceiver in MUSB be managed by an external driver; don't assume it's integrated. OMAP3 chips need it to be external, and there may be ways to interact with the transceiver which add functionality to the system. Platform init code is responsible for setting up the transeciver, probably using the NOP transceiver for integrated transceivers. External ones will use whatever the board init code provided, such as twl4030 or something more hands-off.

The gadget EP0 code routinely ignores an interrupt at end of the data phase because of musb_g_ep0_giveback() resetting the state machine to "idle, waiting for SETUP" phase prematurely. The driver also prematurely leaves the status phase on receiving the SetupEnd interrupt. As there were still unhandled endpoint 0 interrupts happening from time to time after fixing these issues, there turned to be yet another culprit: two distinct gadget states collapsed into one. The (missing) state that comes after STATUS IN/OUT states was typically indiscernible from them since the corresponding interrupts tend to happen within too little period of time (due to only a zero-length status packet in between) and so they got coalesced; yet this state is not the same as the next one which is associated with the reception of a SETUP packet. Adding this extra state seems to have fixed the rest of the unhandled interrupts that generic_interrupt() and davinci_interrupt() hid by faking their result and only emitting a debug message -- so, stop doing that.

The current MUSB host code doesn't make use of all the available FIFOs in for periodic transfers since it wrongly assumes the RX and TX sides of any given hw_ep always share one FIFO. Change: use 'in_qh' and 'out_qh' fields of the 'struct musb_hw_ep' to check the endpoint's business; get rid of the now-unused 'periodic' array in the 'struct musb'. Also optimize a loop induction variable in the endpoint lookup code.
