pull request: wireless-next 2014-10-03
Please pull tihs batch of updates intended for the 3.18 stream!
For the iwlwifi bits, Emmanuel says:
"I have here a few things that depend on the latest mac80211's changes:
RRM, TPC, Quiet Period etc... Eyal keeps improving our rate control
and we have a new device ID. This last patch should probably have
gone to wireless.git, but at that stage, I preferred to send it to
-next and CC stable."
For (most of) the Atheros bits, Kalle says:
"The only new feature is testmode support from me. Ben added a new method
to crash the firmware with an assert for debug purposes. As usual, we
have lots of smaller fixes from Michal. Matteo fixed a Kconfig
dependency with debugfs. I fixed some warnings recently added to
checkpatch."
For the NFC bits, Samuel says:
"We've had major updates for TI and ST Microelectronics drivers, and a
few NCI related changes.
For TI's trf7970a driver:
- Target mode support for trf7970a
- Suspend/resume support for trf7970a
- DT properties additions to handle different quirks
- A bunch of fixes for smartphone IOP related issues
For ST Microelectronics' ST21NFCA and ST21NFCB drivers:
- ISO15693 support for st21nfcb
- checkpatch and sparse related warning fixes
- Code cleanups and a few minor fixes
Finally, Marvell added ISO15693 support to the NCI stack, together with a
couple of NCI fixes."
For the Bluetooth bits, Johan says:
"This 3.18 pull request replaces the one I did on Monday ("bluetooth-next
2014-09-22", which hasn't been pulled yet). The additions since the last
request are:
- SCO connection fix for devices not supporting eSCO
- Cleanups regarding the SCO establishment logic
- Remove unnecessary return value from logging functions
- Header compression fix for 6lowpan
- Cleanups to the ieee802154/mrf24j40 driver
Here's a copy from previous request that this one replaces:
'
Here are some more patches for 3.18. They include various fixes to the
btusb HCI driver, a fix for LE SMP, as well as adding Jukka to the
MAINTAINERS file for generic 6LoWPAN (as requested by Alexander Aring).
I've held on to this pull request a bit since we were waiting for a SCO
related fix to get sorted out first. However, since the merge window is
getting closer I decided not to wait for it. If we do get the fix sorted
out there'll probably be a second small pull request later this week.
'"
And,
"Unless 3.17 gets delayed this will probably be our last -next pull request for
3.18. We've got:
- New Marvell hardware supportr
- Multicast support for 6lowpan
- Several of 6lowpan fixes & cleanups
- Fix for a (false-positive) lockdep warning in L2CAP
- Minor btusb cleanup"
On top of all that comes the usual sort of updates to ath5k, ath9k,
ath10k, brcmfmac, mwifiex, and wil6210. This time around there are
also a number of rtlwifi updates to enable some new hardware and
to reconcile the in-kernel drivers with some newer releases of the
Realtek vendor drivers. Also of note is some device tree work for
the bcma bus.
Please let me know if there are problems!

We need a way to customize the behaviour of the EFI boot stub, in
particular, we need a way to disable the "chunking" workaround, used
when reading files from the EFI System Partition.
One of my machines doesn't cope well when reading files in 1MB chunks to
a buffer above the 4GB mark - it appears that the "chunking" bug
workaround triggers another firmware bug. This was only discovered with
commit 4bf7111f50 ("x86/efi: Support initrd loaded above 4G"), and
that commit is perfectly valid. The symptom I observed was a corrupt
initrd rather than any kind of crash.
efi= is now used to specify EFI parameters in two very different
execution environments, the EFI boot stub and during kernel boot.
There is also a slight performance optimization by enabling efi=nochunk,
but that's offset by the fact that you're more likely to run into
firmware issues, at least on x86. This is the rationale behind leaving
the workaround enabled by default.
Also provide some documentation for EFI_READ_CHUNK_SIZE and why we're
using the current value of 1MB.

The naming convention of this driver was always under the scanner, people
complained that it should have a more generic name than cpu0, as it manages all
CPUs that are sharing clock lines.
Also, in future it will be modified to support any number of clusters with
separate clock/voltage lines.
Lets rename it to 'cpufreq_dt' from 'cpufreq_cpu0'.

Since there's a lot of different functionality in i915_irq.c I've
decided to split it into different sections and pull in just the

When both 'cache-size' and 'cache-sets' are specified for a L2 cache
controller node, parse those properties and set up the
set size based on which type of L2 cache controller we are using.
Update the L2 cache controller Device Tree binding with the optional
'cache-size', 'cache-sets', 'cache-block-size' and 'cache-line-size'
properties. These come from the ePAPR specification.
Using the cache size, number of sets and cache line size we can
calculate desired associativity of the L2 cache. This is done
by the calculation:
set size = cache size / sets
ways = set size / line size
way size = cache size / ways = sets * line size
associativity = cache size / way size
Example output from the PB1176 DT that look like this:
L2: l2-cache {
compatible = "arm,l220-cache";
(...)
arm,override-auxreg;
cache-size = <131072>; // 128kB
cache-sets = <512>;
cache-line-size = <32>;
};
Ends up like this:
L2C OF: override cache size: 131072 bytes (128KB)
L2C OF: override line size: 32 bytes
L2C OF: override way size: 16384 bytes (16KB)
L2C OF: override associativity: 8
L2C: DT/platform modifies aux control register: 0x02020fff -> 0x02030fff
L2C-220 cache controller enabled, 8 ways, 128 kB
L2C-220: CACHE_ID 0x41000486, AUX_CTRL 0x06030fff
Which is consistent with the value earlier hardcoded for the
PB1176 platform.

The Armada SoC family implementation of this SPI hardware module has
extended the configuration register to allow for a wider range of SPI
clock rates. Specifically the Serial Baud Rate Pre-selection bits in the
SPI Interface Configuration Register now also use bits 6 and 7 as well.
Modify the baud rate calculation to handle these differences for the
Armada case. Potentially a baud rate can be setup using a number of
different pre-scalar and scalar combinations. This code tries all
possible pre-scalar divisors (8 in total) to try and find the most
accurate set.
This change introduces (and documents) a new device tree compatible
device name "armada-370-spi" to support this.
