=== Completed work items ===
none this week
=== Plans ===
Vacation 3 days this week and 5 days next week. Back again September 12.
== Highlights ==
* 1:1 with Deepak for the current status sync, concern shared.
* Send email to Will D for the offline cpu to bootloader mode, get
feedback from him and it seems Will get stuck there.
* i.MX6Q (4 Cortex-A9 cores SMP) u-boot upstream preparation.
== Plan ==
* 11.11 task
* i.MX6Q (4 Cortex-A9 cores SMP) u-boot upstream preparation.
Best Regards,
Jason Liu
=== i.MX6Q DT ===
* Rewrote the Freescale internal i.mx6q clock codes. With the common
pattern applied as much as possible, the LOC gets reduced to ~2K
from the original ~5K (including register header).
=== Plan ===
* Post i.mx6q series

Regards,
Shawn
== Manjunatha GK <manjugk> ==
=== Highlights ===
* submitted dt migrated patches(v2) for i2c controller along with
generic board files for omap3 and omap4
* The patch series was missing twl driver handling due platform_data
issue[was waiting for Grant's feedback]
* Benoit has posted patch series on top of v2 which eliminates
aux_data usage and handles twl driver
* was on vacation from 2011-08-29 to 2011-09-02
=== Plans ===
* omap dt migrated patches for i2c, twl and gpio are posted for review comments.
* rework for any comments and target patches for v3.2

* Submitted gic and interrupt combiner controller device tree support
patches for exynos4.
* Submitted rtc device tree support patch for samsung's rtc driver.
* Reviewed Linus W's pinctrl v5 patches and checked suitability for exynos4.
* Started working on device tree support for exynos4 keypad controller driver.
=== Plans ===

* Re-test pl330 dma controller device tree patches with v8 version of
pl330 driver update patches from Boojin Kim.
* Start preparation for single dt-enabled board file for smdkv310 and
origen boards.
=== Misc ===
* Will be on leave on September 9th.
I have put the tools, data and some conclusions from the work I did on
the flash storage performance investigation at
http://yxit.co.uk/public/flash-performance/
Here is a copy of the README file from there...
CONTENTS
doc/benchmark-results
Some conclusions drawn from timings of usecases.
doc/simulation-results
Some conclusions drawn from simulation of SD cards.
flashsim-usecases.sh
This scripts creates a filesystem then runs various usecases on
it whilst blktrace collects traces of the resulting block driver
activity.
traces/
This directory contains some traces already gathered using
flashsim-usecases.sh on some cards described in doc/cards
See traces/README for more.
doc/cards
This file contains results of running flashbench on various
cards.
flashsim/
Program to simulates the various algorithms used by flash
drives. This takes parsed blktrace output from a usecase and
produces an estimate of the write amplification.
process-traces.sh
Script to process the traces in directory traces/ and produce
timings and simulation results using flashsim.
http://git.yxit.co.uk/flashbench.git/
This contains an extension to the flashbench tool write blocks
in various patterns. It is designed as an aid to deducing the
algorithms used by SD cards. See commit

== Linus Walleij linusw ==
=== Highlights ===
* Pushed out v6 (Ice Cream Sanwich) of the pinctrl/pinmux subsystem:
http://marc.info/?l=linux-kernel&m=131486959614376&w=2
finally some consensus is building up with nVidia folks
* Found a regression in the Integrator resulting from PCI
consolidation work as part of hardware.h cleanup work.
http://marc.info/?l=linux-arm-kernel&m=131517245610289&w=2
* Discussed a standardized secure world interface through
Global Platforms TEE. Apparently there are many
stakeholders in this consortium.
=== Plans ===
* Help Niklas get device tree going
* v7 (Janitor) iteration of the pinctrl + pinmux subsystem
* Third round around the gpio.h cleanups.
* Test the PL08x patches on the Ericsson Research
PB11MPCore and submit platform data for using
pl08x DMA on that platform.
* Drive generalization of U300 and Nomadik GPIO
* Get into struct clk generalization and movement of clk
drivers into drivers/clk - handover from Jeremy Kerr.
We will do this in Cambridge or something like that.
* Watch the DBx500 PRCMU drivers update
=== Issues ===
* Shanghaiied for internal advisory at ST-Ericsson for
say 19% of working hours last week.
Thanks,
Linus Walleij
=== Highlights ===
* Did an IBM internal presentation on Android and how Linaro is helping
* Worked on my Kconfig talk for Linux Plumbers.
* Implemented the proposed config tooling for config fragments, as
discussed in my Kconfig talk.
* Did Beagle XM testing for the 11.08-rc Android Platform Images.
* Made final 11.08 linaro+android kernel, and managed to push it
properly through Gerrit
* Pinged Ingo about patches for 3.1 I sent to tglx, which haven't yet
been merged.
=== Plans ===
* On vacation until Linux Plumbers Conf. Will effectively be out for the
next two weeks.
=== Issues ===
* Number of patches queued for 3.1 still haven't been pulled into -tip
because of Thomas being offline. Concerned they might not make the 3.1
release while I'm out of town.
