Status: https://wiki.linaro.org/OfficeofCTO/WeeklyReport Weekly meeting minutes: https://wiki.linaro.org/OfficeofCTO/2011-09-27 Highlights: -- Connect: preparing the sessions for STB, Server and 1 session on IVI. -- For 1109 several items did not reach enough results in order to announce/highlight as part of the release highlights. The status report above contains information on what was completed and what will be pushed to 11.10 -- ARMHF: + completing the ARMHF benchmarks, fixing + there was a report posted in http://lists.linaro.org/pipermail/cross-distro/2011-September/000054.html highlighting the major GNU/Linux distributors agreement on the technical configuration of ARM “hard-float” ports to keep binaries compatibles across distributions + Also Steve McIntyre is going to tend to the build farm of ARMHF (plus set a backup in case some of the boards are not running - eg due to a power failure), and push a toolchain patch to detect FP -- this is now less of an issue as we're going to use separate pathnames for armhf -- Boot architecture: plans are taking shape and Linaro will expand into doing UEFI related work and join UEFI. Several meetings have already taken place, there is a growing interest towards secure boot, and having a position over that technology from ARM platform and Linux perspectives -- ARM Server - Clobber setup is tested and documented (https://wiki.linaro.org/OfficeofCTO/NetworkBoot), also fixing errors and identifying problems related to that setup. Please let me know if there are any questions Best, -- Ilias Biris ilias.biris(a)linaro.org Project Manager, Linaro M: +358504839608, IRC: ibiris Skype: ilias_biris Linaro.org│ Open source software for ARM SoCs

[ANN] Linaro CI Build Service 11.09

by Deepti Kalakeri

Hello All, As part of greater Continuous Integration (CI) efforts at Linaro, the Infrastructure Team is tasked to develop and maintain a jenkins based, versatile service run in the cloud that will drive the build part of the continuous integration loop for engineering components. After an intense 11.09 cycle focused on developing a solution for doing large scale kernel CI building and testing, we are pleased to announce that the Linaro CI build service is now available for wider beta testing for L inaro engineering teams. If you are interested in trying out this service or if you have a kernel tree/defconfig that you would like to be continuously built on Linaro CI and tested in Linaro's LAVA lab, please get in touch with me and the infrastructure team, to discuss your steps to get started. Expect more updates and information from the Linaro CI front as we proceed. In the meantime visit the links below: 1. The Linaro CI Build service + https://ci.linaro.org 2. Details and background on the CI build service and how to request a new job + https://wiki.linaro.org/Platform/Infrastructure/LinaroCI 3. The list of the existing Kernel CI builds that are currently built and tested on daily basis can be found at + https://ci.linaro.org/jenkins/view/All%20CI/ 4. Daily tracking your Kernel CI build results is explained here + https://wiki.linaro.org/Platform/Infrastructure/LinaroCI#Monitoring_Build_F… 5. Daily tracking your Kernel CI runtime results is explained there + https://wiki.linaro.org/Platform/Infrastructure/LinaroCI#Finding_Test_Resul… 6. Future development ideas for the service + https://launchpad.net/linaro-ci/+milestone/backlog The 11.09 release is just a first step and more exciting and advanced continuous integration features are on their way. Linaro CI has already started showing results by finding bugs during our development/setup phase of Linaro CI build service. Visit our backlog milestone [6] in launchpad to get an up to date overview of ideas and deliverables in our planning pipeline. Here some samples of topics we discussed: 1. Extend the kernel CI effort by adopting further defconfigs and tracked trees and verification of the kernel builds on different kinds of boards in the LAVA lab. 2. Develop and host a one stop place for kernel CI tracking on LAVA dashboard, where engineers can continuously monitor their components for build and runtime failures. 3. Add support for adhoc kernel builds. This will allow kernel tree maintainers to try out pull requests and local developments in LAVA using a simple one time submit feature. 4. Improve CI support for downstream kernel maintainers (e.g. ubuntu, android). The goal is to make continuous downstream merging and integration of highly active upstream repositories very easy and efficient. The beginning of many milestones has just begin with a small step and your feedback will be of immense value in achieving the future milestones.

[Patch v4 08/11] Touch: DA9052 touchscreen driver

by ashishj3

This driver add support for DA9052 4-wire resistive ADC interfaced touchscreen controller. DA9052 is a MFD therefore this driver depends on DA9052 core driver for core functionalities. Signed-off-by: David Dajun Chen <dchen(a)diasemi.com> Signed-off-by: Ashish Jangam <ashish.jangam(a)kpitcummins.com> --- Changes since v4: - Add string "compile this driver as module" in kconfig - Replace struct da9052_tsi_reg with temp variable - Call schedule_delayed_work() from pen down irq handler - Mask data ready irq in pen up work - Disable IRQs in device close and enable it in device open - Remove set_bit() for ABS X,Y,Pressure as input_set_abs_params() does it Changes since v3: - Remove unrequire type cast - Prefix init code with _devinit - Remove check for workqueue reschedule - tsi_close() to wait for datardy intr completion - Remove seperate workqueue - Move cancel_work_sync to tsi_close() - Check for drv data before tsi priv data allocation Changes since v2: - Replace kthreads with workqueue - Remove kfifos - Taken care for bus type - Replace da9052_set/clear function with da9052_reg_update - Add open and close functionality --- drivers/input/touchscreen/Kconfig | 10 + drivers/input/touchscreen/Makefile | 1 + drivers/input/touchscreen/da9052_tsi.c | 374 ++++++++++++++++++++++++++++++++ 3 files changed, 385 insertions(+), 0 deletions(-) create mode 100755 drivers/input/touchscreen/da9052_tsi.c diff --git a/drivers/input/touchscreen/Kconfig b/drivers/input/touchscreen/Kconfig index cabd9e5..e4e3341 100644 --- a/drivers/input/touchscreen/Kconfig +++ b/drivers/input/touchscreen/Kconfig @@ -144,6 +144,16 @@ config TOUCHSCREEN_DA9034 Say Y here to enable the support for the touchscreen found on Dialog Semiconductor DA9034 PMIC. +config TOUCHSCREEN_DA9052 + tristate "Dialog DA9052 TSI" + depends on PMIC_DA9052 + help + Say y here to support the touchscreen found on + Dialog Semiconductor DA9052 PMIC + + To compile this driver as a module, choose M here: the + module will be called da9052-tsi. + config TOUCHSCREEN_DYNAPRO tristate "Dynapro serial touchscreen" select SERIO diff --git a/drivers/input/touchscreen/Makefile b/drivers/input/touchscreen/Makefile index 282d6f7..a4aeb25 100644 --- a/drivers/input/touchscreen/Makefile +++ b/drivers/input/touchscreen/Makefile @@ -18,6 +18,7 @@ obj-$(CONFIG_TOUCHSCREEN_BITSY) += h3600_ts_input.o obj-$(CONFIG_TOUCHSCREEN_BU21013) += bu21013_ts.o obj-$(CONFIG_TOUCHSCREEN_CY8CTMG110) += cy8ctmg110_ts.o obj-$(CONFIG_TOUCHSCREEN_DA9034) += da9034-ts.o +obj-$(CONFIG_TOUCHSCREEN_DA9052) += da9052_tsi.o obj-$(CONFIG_TOUCHSCREEN_DYNAPRO) += dynapro.o obj-$(CONFIG_TOUCHSCREEN_HAMPSHIRE) += hampshire.o obj-$(CONFIG_TOUCHSCREEN_GUNZE) += gunze.o diff --git a/drivers/input/touchscreen/da9052_tsi.c b/drivers/input/touchscreen/da9052_tsi.c new file mode 100755 index 0000000..e7418b3 --- /dev/null +++ b/drivers/input/touchscreen/da9052_tsi.c @@ -0,0 +1,374 @@ +/* + * TSI driver for Dialog DA9052 + * + * Copyright(c) 2011 Dialog Semiconductor Ltd. + * + * Author: David Dajun Chen <dchen(a)diasemi.com> + * + * This program is free software;

wiki feedback on new front page

by Andy Doan

Michael and I were tasked with making the front page of the Linaro wiki a little more developer focused and offloading some of the other information to the main website, linaro.org. We've put together a prototype page and would like to get some feedback before making the real switch: https://wiki.linaro.org/AndyDoan/Sandbox/FrontPage thanks, -andy
