[ACTIVITY] (John Stultz) Dec 5th - 9th

by John Stultz

=== Highlights === * Synced with GregKH on plans for adding some android patches to staging. * Reworked Android ashmem patches so they could be included in staging. Sent out for review to Greg and Android team. Got some feedback from Arve, and am working to address his concerns. * Worked out what other Android patches were necessary to get the staging kernel up and running with ICS (luckily, its only one more patch in addition to the ashmem changes). * Starting looking at requirements to get Android alarm-timer driver (and the pending patches I have to simplify the driver and make it use the upstreamed posix alarm timer code) into staging. * Sent mail to Andrey Konovalov with overview of the old linaro+android kernel maintenance process, and my understanding of the new goals around linaro kernel tree maintenance going forward. * Due to the shortened schedule this month, released an initial 11.12 Linaro+Android kernel so there is something to work with while Andrey ramps up to speed. === Plans === * Continue working to get ashmem patches for staging reviewed and acked by Android team. Push resulting queue to Greg. * Continue looking at android alarmtimer driver for staging. It requires the wakelock patches, so either I cut out wakelocks or wait for some form of wakelocks to go upstream. * Look into what other bits from the Android patch set could possibly go into staging. * Address the SCHEC_MC option getting dropped from android defconfigs. * Try to send the timekeeping locking changes to tglx. === Issues === * None.

[ACTIVITY][weekly][linaro] (Saugata Das) 2011-12-05 - 2011-12-09

by Saugata Das

== Saugata Das sdas == === Activity Summary === * Continued review and follow up on MMC-4.5 patches with Samsung. Helping on power OFF notify patch * Studying the blueprint for file system block size > 4KB, https://blueprints.launchpad.net/linux-linaro/+spec/vfs-larger-than-4k-bloc… * Studying the blueprint for data tag and context ID, https://blueprints.launchpad.net/linux-linaro/+spec/linaro-kernel-emmc4.5-c… === Plans === * Propose the data tag patch within next two weeks === Issues === * In order to use the Samsung 4.5 eMMC sample, we need to do hardware modification, which needs specialised equipments. Will need sometime to prepare the setup for verification of 4.5 patches.

[ACTIVITY][weekly][linaro] (Dave Martin) 2011-12-05 - 2011-12-09

by Dave Martin

== Dave Martin <dmart> == === Activity Summary === * Reviewing of Pawel's versatile express patches and related discussions (steadily progressing -- there are a few issues to resolve, but the series appears almost ready. Some issues came up when testing.) * Concluded that we should fix drivers to stop using NO_IRQ or assuming NO_IRQ == -1 on an as-needed basis. * Worked on some miscellaneous patches to do some Kconfig cleanup, a couple of errata workarounds relevant to vexpress etc. === Plans === * Propose AMBA driver changes to replace NO_IRQ with a test compatible with the "0 means no irq" convention. * Repost l2x0 Kconfig cleanup patches along with patch to clean up the dependencies of CONFIG_SMP. * Continue to miscellaneous outstanding DT issues (bindings, drivers) forward. === Work Items === https://blueprints.launchpad.net/linux-linaro/+spec/kernel-versatile-boad-d…: * Document outstanding AMBA tree bindings: INPROGRESS * Propose of/irq and/or AMBA driver changes to resolve NO_IRQ iinterface mismatch between OF drivers and (currently breaking pata_generic on vexpress): INPROGRESS * Post outstanding AMBA tree bindings upstream: TODO === Absences === Christmas (2011-12-19 - 2012-01-03)

[ACTIVITY] (Linus Walleij) 2011-12-03 - 2011-12-09

by Linus Walleij

== Linus Walleij linusw == === Highlights === * Sent out v6 of the pin config patch series - it is now stable, and functionality is in linux-next. * Working on generic pin config for ASICs that want to keep things simple. * Discussed DT mappings to pin controllers with Stephen Warren and Tony Lindgren. No consensus reached. * Ux500 mainlining since too little is happening: - Iterated AB5500 high voltage LEDs driver. * Reviewed the Switch class derived from Android by Samsung. This is very important stuff I feel. * Helped Sjur Brændeland to get M7400 XSHM patches into linux-next and will help him to establish a k.org repository. * Reviewed som MMC patch... === Plans === * Vacation 2011-12-19 thru 2012-01-06 * Drive generalization of Nomadik GPIO by using the pinctrl framework. drivers/gpio/gpio-nomadik.c * Test the PL08x patches on the Ericsson Research PB11MPCore and submit platform data for using pl08x DMA on that platform. * Look into other Ux500 stuff in need of mainlining... like the HWMON stuff. === Issues === * None, apart from some ST-Ericsson internal stuff. Thanks, Linus Walleij

[ACTIVITY] (Rajendra Nayak) Nov 28 - Dec 02

by Rajendra Nayak

== Rajendra Nayak <rnayak> == === Highlights === * Added support for pin-configuration for OMAP4 using the v4 of the pinconf core support patches. Data still in the driver and not moved to dt. Waiting on Tony;s series/patches for DT support and moving data out of the drivers. * Started looking at clock bindings and generic struct clock support patches. Experimented with moving OMAP clock data to dt which started to look very complex (moving all clock data). Had a call with Benoit/ Mike on this and for now working on moving only leaf clocks/mappings to dt keeping the rest of the clock tree in kernel. * omap-serial dt support patches acked by Rob. * Working with Aneesh V on omap4 EMIF driver dt support doing initial reviews. === Plans === * Repost TWL regulator support. (Still waiting for a repost of omap i2c/twl DT support patches) * Refine the experimental patches to move OMAP clock data to dt. * Rework some of the pinmux/pinconf support on top of changes Tony has been proposing/working on once they are available. === Misc === * Will be taking off the week before Xmas (19th to 23rd Dec) and work through the Xmas week.
