      omap: headers: Move remaining headers from include/mach to include/plat · ce491cf8
      由 Tony Lindgren 提交于 
      Move the remaining headers under plat-omap/include/mach
to plat-omap/include/plat. Also search and replace the
files using these headers to include using the right path.

This was done with:

#!/bin/bash
mach_dir_old="arch/arm/plat-omap/include/mach"
plat_dir_new="arch/arm/plat-omap/include/plat"
headers=$(cd $mach_dir_old && ls *.h)
omap_dirs="arch/arm/*omap*/ \
drivers/video/omap \
sound/soc/omap"
other_files="drivers/leds/leds-ams-delta.c \
drivers/mfd/menelaus.c \
drivers/mfd/twl4030-core.c \
drivers/mtd/nand/ams-delta.c"

for header in $headers; do
	old="#include <mach\/$header"
	new="#include <plat\/$header"
	for dir in $omap_dirs; do
		find $dir -type f -name \*.[chS] | \
			xargs sed -i "s/$old/$new/"
	done
	find drivers/ -type f -name \*omap*.[chS] | \
		xargs sed -i "s/$old/$new/"
	for file in $other_files; do
		sed -i "s/$old/$new/" $file
	done
done

for header in $(ls $mach_dir_old/*.h); do
	git mv $header $plat_dir_new/
done

      usb: musb: disable OTG AUTOIDLE only with omap3430 · 9a4b5e36
      由 Niilo Minkkinen 提交于 
      Omap3 MUSB AUTOIDLE functionality configured through OTG_SYSCONFIG
register prevents the device from going into retention.
This is a workaround (by Richard Woodruff/TI), as his comment :
> A new MUSB bug which is a match to data below was identified very
> recently (on hardware and in simulation).
> This bug is in 3430 and not 3630.
> As a priority test (and as new default) you should have engineers
> disable autoidle for MUSB block.
> This is the workaround which will show up in next errata.

      musb: add high bandwidth ISO support · a483d706
      由 Ajay Kumar Gupta 提交于 
      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.  (This is the only
gadget driver known to use enough endpoints to notice the change.)

      musb: use dma mode 1 for TX if transfer size equals maxpacket (v2) · d1043a26
      由 Anand Gadiyar 提交于 
      Currently, with Inventra DMA, we use Mode 0 if transfer size is less
than or equal to the endpoint's maxpacket size.  This requires that
we explicitly set TXPKTRDY for that transfer.

However the musb_g_tx code will not set TXPKTRDY twice if the last
transfer is exactly equal to maxpacket, even if request->zero is set.
Using Mode 1 will solve this; a better fix might be in musb_g_tx().

Without this change, musb will not correctly send out a ZLP if the
last transfer is the maxpacket size and request->zero is set.

      musb: support disconnect after HNP roleswitch · ab983f2a
      由 David Brownell 提交于 
      Adjust HNP state machines in MUSB driver so that they handle the
case where the cable is disconnected.  The A-side machine was
very wrong (unrecoverable); the B-Side was much less so.

 - A_PERIPHERAL ... as usual, the non-observability of the ID
   pin through Mentor's registers makes trouble.  We can't go
   directly to A_WAIT_VFALL to end the session and start the
   disconnect processing.  We can however sense link suspending,
   go to A_WAIT_BCON, and from there use OTG timeouts to finally
   trigger that A_WAIT_VFALL transition.  (Hoping that nobody
   reconnects quickly to that port and notices the wrong state.)

 - B_HOST ... actually clear the Host Request (HR) bit as the
   messages say, disconnect the peripheral from the root hub,
   and don't detour through a suspend state.  (In some cases
   this would eventually have cleaned up.)

Also adjust the A_SUSPEND transition to respect the A_AIDL_BDIS
timeout, so if HNP doesn't trigger quickly enough the A_WAIT_VFALL
transition happens as it should.

      musb: make initial HNP roleswitch work (v2) · 1de00dae
      由 David Brownell 提交于 
      Minor HNP bugfixes, so the initial role switch works:

 - A-Device:
     * disconnect-during-suspend enters A_PERIPHERAL state
     * kill OTG timer after reset as A_PERIPHERAL ...
     * ... and also pass that reset to the gadget
     * once HNP succeeds, clear the "ignore_disconnect" flag
     * from A_PERIPHERAL, disconnect transitions to A_WAIT_BCON

 - B-Device:
     * kill OTG timer on entry to B_HOST state (HNP succeeded)
     * once HNP succeeds, clear "ignore_disconnect" flag
     * kick the root hub only _after_ the state is adjusted

Other state transitions are left alone.  Notably, exit paths from
the "roles have switched" state ... A_PERIPHERAL handling of that
stays seriously broken.

      musb: otg timer cleanup · f7f9d63e
      由 David Brownell 提交于 
      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.

      musb: proper hookup to transceiver drivers · 84e250ff
      由 David Brownell 提交于 
      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.
