* 'i2c-fixes' of git://aeryn.fluff.org.uk/bjdooks/linux:
i2c-s3c2410: fix check for being in suspend.
i2c-cpm: Detect and report NAK right away instead of timing out
|
| | |
| |
| |
| |
| |
| |
| |
| |
| |
| |
| |
| | |
As noted by Julia Lawall <julia@diku.dk>, we can never
trigger the check for being in suspend due to the result
of !readl(i2c->regs + S3C2410_IICCON) & S3C2410_IICCON_IRQEN
always being 0.
Add suspend/resume hooks to stop i2c transactions happening
until the driver has been resumed.

Make the driver report an ENXIO error immediately upon NAK instead of
waiting for another interrupt and getting a timeout.
When reading from a device that is not present or declines to respond
to, e.g., a non-existent register address, CPM immediately reports a
NAK condition in the TxBD, but the driver kept waiting until a timeout,
which takes 1 second and causes an ugly console error message.

This patch adds the "Superial" USB-Serial converter to pl2303 so that it
is detected, by the correct driver. Adds the relevant vendor:product
(5372:2303) to the device tables in pl2303.c & pl2303.h. The patch has
been tested against 2.6.24-22-generic.

When a driver unbinds from an interface, usbcore always sends a
Set-Interface request to reinstall altsetting 0. Unforunately, quite
a few devices have buggy firmware that crashes when it receives this
request.
To avoid such problems, this patch (as1180) arranges to send the
Set-Interface request only when the interface is not already in
altsetting 0.

The following patch adds in the USB PID for Ewert Energy System's CANdapter
device (CANBUS to USB-Serial which uses the FTDI 245R chipset) to the ftdi_sio
device driver.
The patch was tested successfully on Linux kernel 2.6.27 under Ubuntu.

The usbtmc driver forgot to export its device table to userspace.
Without this, it is never loaded properly when such a device is seen by

During a reset, releasing the swflag after it failed to be acquired would
cause a double unlock of the mutex. Instead, test whether acquisition of
the swflag was successful and if not, do not release the swflag. The reset
must still be done to bring the device to a quiescent state.

Attached is a patch which improves the output of ethtool (see below)
to some sensefull values with a sungem fibre card which uses the
sungem interal pcs connected to a serdes chip. The seriallink case in
the driver is untouched.
Most values are hardcoded, because gigabit fibre autoneg is anyways
limited and the driver don't really support much at the moment with
that hardware.

As reported by Hermann Lauer, PCS PHY support in the sungem
driver simply doesn't work.
When the chip is reset due to open, or some other similar operation,
the PCS is reset too but we don't program it back into a running
state. The result is no link when the device is brought up.
This partially rectifies the situation for the moment, by kicking
the PCS after a sungem chip reset so that it will renegotiate and
be re-enabled again.
The behavior is still a little bit dodgy as the added renegotiate
make the link take some time after bringing the interface up,
but this is a significant improvement in that things actually work
now :-)
Based almost entirely upon an initial patch by Hermann.

The test-unit-ready portion of this patch was causing boots to fail on
my test machine (as in http://lkml.org/lkml/2008/12/5/161). With this
patch in place, the system is booting reliably.
Mike Anderson found the same problem in the hp_hw_start_stop code,
and I applied the same solution in cdrom_read_cdda_bpc.

For the console, there is a 1:1 mapping of glyphs which cannot be found
in the current font. This seems to be meant as a kind of 'emergency
fallback' for fonts without unicode mapping which otherwise would
display nothing readable on the screen.
At the moment it affects all chars for which no substitution character
is defined. In particular this means that for all chars (>= 128) where
there is no iso88591-1/unicode character (e.g. control character area)
you'll get the very strange 1:1 mapping of the (cp437) graphics card
glyphs.
I'm pretty sure that the 1:1 mapping should only affect strict ASCII
code characters, i.e. chars < 128.
The patch limits the mapping as it probably was meant anyway.

There is a major bug in the cp437 to unicode translation table. Char
0x7c is mapped to U+00a5 which is the Yen sign and wrong. The right
mapping is U+00a6 (broken bar).
Furthermore, a mapping for U+00b4 (a widely used character) is missing
even though easily possible.
The patch fixes these, as well as it provides a few other useful
mappings.
The changes are as follows:
0x0f (enhancement) enables a sort of currency symbol
0x27 (bug) enables a sort of acute accent which is a widely used character
0x44 (enhancement) enables a sort of icelandic capital letter eth
0x7c (major bug) corrects mapping
0xeb (enhancement) enables a sort of icelandic small letter eth
0xee (enhancement) enables a sort of math 'element of'

- f3179748a157c21d44d929fd3779421ebfbeaa93 "radeonfb: Disable new color

In pci_create_slot(), the local variable 'slot_name' is allocated by
make_slot_name(), but never freed. We never use it after passing it to
the kobject core, so we should free it upon function exit.

The pktcdvd created class devices only export some sysfs files,
but have no char dev_t registered in the driver.
At class device creation time they copy the dev_t value of the
block device to the char device, wich will register a new char
device in the driver core and userspace, with a conflicting dev_t
value.
In many cases the class devices dev_t just points to a random
USB device. This fixes the sysfs "duplicate entry" errors.

The firewire nodemanager function "nodemgr_host_thread" contains a loop
that calls try_to_freeze near the top of the loop, but then delays for
up to 3.25 seconds (plus time to do work) before getting back to the top
of the loop. When starting a cycle post-boot, this doesn't seem to bite,
but it is causing a noticeable delay at boot time, when freezing
processes prior to starting to read the image.
The following patch adds invocation of try_to_freeze to the subloops
that are used in the body of this function. With these additions, the
time to freeze when starting to resume at boot time is virtually zero.
I'm no expert on firewire, and so don't know that we shouldn't check
the return value and jump back to the top of the loop or such like after
being frozen, but I submit it for your consideration.

The delay until nodemgr freezes was up to 0.25s (plus time for node
probes) in Linux 2.6.27 and older and up to 3.25s (plus ~) since Linux
2.6.28-rc1, hence much more noticeable.
try_to_freeze() without any jump is correct. The surrounding code in
the respective loops will catch whether another bus reset happens during
the freeze and handle it.
