USB: xhci: Set TD size in transfer TRB.

The 0.95 xHCI specification requires software to set the "TD size" field
in each transaction request block (TRB).  This field gives the host
controller an indication of how much data is remaining in the TD
(including the buffer in the current TRB).  Set this field in bulk TRBs
and data stage TRBs for control transfers.

USB: musb: fix CONFIGDATA register read issue

INDEX register has to be set to '0' before reading
CONFIGDATA register which is only present in TI musb
platforms.

Currently the default register access mode is set to
FLAT_MODE thus INDEX register is not getting set
properly with musb_ep_select() which is just a nop
operation in FLAT_MODE.This invalid register read is

10 years agoUSB: aten uc2324 is really a moschip 7840
Russell Lang [Fri, 17 Jul 2009 09:29:20 +0000]
USB: aten uc2324 is really a moschip 7840

I've opened up the case, and the chips in the ATEN UC2324 are:

Moschip
MCS7840CV-AA
69507-6B1
0650
(USB to 4-port serial)

(logo with AF kerned together)  0748
24BC02
SINGLP
(unknown 8-pin chip)

(logo looks like 3 or Z in circle)
ZT3243LEEA    0752
B7A16420.T
(4 chips, so this will be RS232 line driver)
(Probably equivalent of Sipex SP3243)

So the ATEN 2324 (aten2011.c driver), is definitely the Moschip 7840,
and should use the mos7840.c driver.  I expect you will remove the
aten2011.c driver from the staging area.

From the aten2011.c source code, the device ID for the UC2322 (2 port
serial) is 0x7820, just like the Moschip evaluation board.  This value
should be added to the device id table of mos7840.c.

Here's a patch that adds these devices to the driver.

USB: ehci-orion: Call ehci_reset before ehci_halt

I noticed that USB initialization didn't setup correctly on my kirkwood
based board (OpenRD base) if I hadn't initialized USB in U-boot first.
The error message looks like this:

  ehci_hcd: USB 2.0 'Enhanced' Host Controller (EHCI) Driver
  orion-ehci orion-ehci.0: Marvell Orion EHCI
  orion-ehci orion-ehci.0: new USB bus registered, assigned bus number 1
  orion-ehci orion-ehci.0: can't setup
  orion-ehci orion-ehci.0: USB bus 1 deregistered
  orion-ehci orion-ehci.0: init orion-ehci.0 fail, -110
  orion-ehci: probe of orion-ehci.0 failed with error -110

which is caused by ehci_halt() timing out in the handshake() call. I
noticed that U-boot does a reset before calling handshake(), so this
patch does the same thing for Linux. USB now works for me.

USB: storage: raise timeout in usb_stor_Bulk_max_lun

Requests to get max LUN, for certain USB storage devices, require a
longer timeout before a correct reply is returned. This happens for a
Realtek USB Card Reader (0bda:0152), which has a max LUN of 3 but is set
to 0, thus losing functionality, because of the timeout occurring too
quickly.

to return a correct max LUN value as well.

10 years agomm: Pass virtual address to [__]p{te,ud,md}_free_tlb()
Benjamin Herrenschmidt [Wed, 22 Jul 2009 05:44:28 +0000]
mm: Pass virtual address to [__]p{te,ud,md}_free_tlb()

mm: Pass virtual address to [__]p{te,ud,md}_free_tlb()

Upcoming paches to support the new 64-bit "BookE" powerpc architecture
will need to have the virtual address corresponding to PTE page when
freeing it, due to the way the HW table walker works.

Basically, the TLB can be loaded with "large" pages that cover the whole
virtual space (well, sort-of, half of it actually) represented by a PTE
page, and which contain an "indirect" bit indicating that this TLB entry
RPN points to an array of PTEs from which the TLB can then create direct
entries. Thus, in order to invalidate those when PTE pages are deleted,
we need the virtual address to pass to tlbilx or tlbivax instructions.

The old trick of sticking it somewhere in the PTE page struct page sucks
too much, the address is almost readily available in all call sites and
almost everybody implemets these as macros, so we may as well add the
argument everywhere. I added it to the pmd and pud variants for consistency.

When a net device goes down or when the bnx2i driver is unloaded,
the code was not generating the ISCSI_KEVENT_IF_DOWN message
properly and this could cause the userspace driver to crash.

Also, based on experimentation, it was noticed that the Silvercrest is

While trying to fix an mt9v001 webcam, I noticed that HSCALE/VSCALE do
work with em28xx + webcam. The issue is that the scaling setup depends
on the number of visible rows/cols of the input image.

With mt9v011 (Silvercrest), the resolution is 640x480. So, the scaling
is different from a normal TV image (720x480 on NTSC). This were causing
a wrong scaling and a previous patch disabled scaling.

As each sensor have their different resolution setting, the xres/yres
should be adjusted accordingly with the input sensor.

V4L/DVB (12235): em28xx: detects sensors also with the generic em2750/2750 entry

Webcams in general don't have eeprom. So, the sensor hint code should be
called to properly detect what sensor is inside.
