The tidy_up() function is only called by the (*detach). That function
unlinks any running urbs and frees all the allocated urbs and buffers
used by the driver.

Rename tidy_up() to usbdux_free_usb_buffers() and move all the parts
that don't deal with the freeing of the buffers directly into the
(*detach).

Also, remove all the unnecessary clearing of the pointers. The comedi
core will kfree() the private data after calling the (*detach).

Foe aesthetic reasons, do the kfree()'ing of the buffers and urbs in
the reverse order that they were allocated.

staging/lustre/obdclass: use a dummy structure for lu_ref_link

Move the definition of struct lu_ref_link to lu_ref.h.  If USE_LU_REF
is not defined then define it to be the empty struct.  Change the
return type of lu_ref_add() and lu_ref_add_atomic() to void.  Add
lu_ref_add_at() taking same arguments as lu_ref_add() togerther with a
pointer to a struct lu_ref_link and returning void.  Adjust all
structures containing a lu_ref_link pointer to contain a struct
lu_ref_link instead.  Use lu_ref_add_at() and lu_ref_del_at() to
handle embedded lu_ref_links.

[Original patch mainly changes lu_ref.[ch] but in upstream client we don't
have lu_ref code in the hope of moving to kobject refcounting. So the patch
only picks the other pieces of original patch, in order to keep code in
sync and make it easier to port future patches.]

it, or the code was changed to disable it for testing), let the usb core
know about this by clearing hcd->self.uses_dma.

By default, the usb core assumes that dma is used when a dma_mask is
set, but this might not always match the dma_enable value in dwc2. To
prevent problems resulting from a mismatch, better to explicitely
disable dma in this case (though everything seemed to work with the
wrong value of uses_dma as well, probably only resulted in some unneeded
work).

staging: dwc2: disable dma when no dma_mask was setup

If the platform or bus driver failed to setup a dma_mask, but the
hardware advertises support for DMA, before DMA would be enabled in
dwc2, but disabled in the usb core, making all connectivity break.

With this commit, the dwc2 driver will emit a warning and fall back to
slave mode in this case.

Note that since commit 642f2ec (staging: dwc2: Fix dma-enabled platform
devices using a default dma_mask) the platform bindings make sure a DMA
mask is always present, but having this check here anyway is probably a
good from a defensive programming standpoint (in case of changes to
platform.c or addition of new glue layers).

11 years agostaging: dwc2: add driver parameter to set AHB config register value
Paul Zimmerman [Tue, 16 Jul 2013 19:22:12 +0000 (12:22 -0700)]
staging: dwc2: add driver parameter to set AHB config register value

The dwc2 driver sets the value of the DWC2 GAHBCFG register to 0x6,
which is GAHBCFG_HBSTLEN_INCR4. But different platforms may require
different values. In particular, the Broadcom 2835 SOC used in the
Raspberry Pi needs a value of 0x10, otherwise the DWC2 controller
stops working after a short period of heavy USB traffic.

So this patch adds another driver parameter named 'ahbcfg'. The
default value is 0x6. Any platform needing a different value should
add a DT attribute to set it.

This patch also removes the 'ahb_single' driver parameter, since
that bit can now be set using 'ahbcfg'.

This patch does not add DT support to platform.c, I will leave that
to whoever owns the first platform that needs a non-default value.
