[PATCH V4 0/5] Add MX51 basic DT support

by Jason Liu

From: Jason Liu <Jason Liu jason.hui(a)linaro.org> This patchset adds Freescale i.mx51 device tree support. This is based on git://git.secretlab.ca/git/linux-2.6 devicetree/test This patch has been tested on MX51 babbage board and can boot up succesfully to linux console with DT enabled. Grant, I think it's almost ready for you to merge it. V4: - Add Linaro sign off and copyrightt V3: - prefix the property name with the vendor name as like: "fsl,has-rts-cts" and "fsl,irda-mode" - use the ttymxc0 as the console - add FEC support, nfs can be used now Jason Liu (5): arm/dt: add basic mx51 device tree support arm/dt: add very basic dts file for babbage board serial/imx: parse from device tree support net/fec: check id_entry pointer before using it net/fec: add device tree matching support arch/arm/boot/dts/babbage.dts | 122 +++++++++++++++++++++++++++++++ arch/arm/mach-mx5/Kconfig | 8 ++ arch/arm/mach-mx5/Makefile | 1 + arch/arm/mach-mx5/board-dt.c | 65 ++++++++++++++++ arch/arm/mach-mx5/clock-mx51-mx53.c | 43 +++++++++++- arch/arm/plat-mxc/include/mach/common.h | 1 + drivers/net/fec.c | 25 +++++-- drivers/tty/serial/imx.c | 79 +++++++++++++++++--- 8 files changed, 327 insertions(+), 17 deletions(-) create mode 100644 arch/arm/boot/dts/babbage.dts create mode 100644 arch/arm/mach-mx5/board-dt.c

linaro android build system issues

by Michael Hudson-Doyle

Hi all, For some reason the jenkins instance that powers the android build system isn't auto provisioning slaves from ec2, so builds are being queued but not executed. If you notice this happen and it's blocking you, get an admin (asac, loic, patryk) to go to https://android-build.linaro.org/jenkins/computer/ and click the "provision via ec2" button, and a slave will be started and run the builds. You can click it more than once to get multiple slaves to clear the queue more quickly. The slaves will be de-provisioned after they have been idle for a little while, so we don't need to manually clean up after ourselves. I'll try and figure out what's going on and fix it next week. Cheers, mwh

[PATCH 0/5] add full platform dt clock support for mx51 babbage

by Shawn Guo

This patch set is to add full platform dt clock support for mx51 babbage, based on Jason's basic-mx51-dt patch. All mx51 non-dt clocks in clock-mx51-mx53.c are translated to dt ones. Shawn Guo (5): arm/dts: babbage: add all available clock nodes arm/mxc: add clk member 'rate' to ease dt fixed-clock support arm/dt: mx51: dynamically add clocks per dt nodes arm/dt: mx5: change timer init function to dt clock way of/clock: eliminate function __of_clk_get_from_provider arch/arm/boot/dts/babbage.dts | 495 +++++++++++- arch/arm/mach-mx5/board-dt.c | 9 +- arch/arm/mach-mx5/clock-mx51-mx53.c | 1401 +++++++++++++++++++++++++++++++- arch/arm/plat-mxc/include/mach/clock.h | 4 + drivers/of/clock.c | 23 +- 5 files changed, 1886 insertions(+), 46 deletions(-) Regards, Shawn

LAVA integration effort for Android validation

by Jeremy Chang

Hi, list: I am working on Validation part for Android, in which mainly inclusive of integrating existing benchmark and testing suites into abrek, like 0xbench and android CTS. For now in my thought, if these benchmark/testing can integrate with abrek, then it should be no much problem or extra effort for integrating further into LAVA. Though I have some questions regarding to validation. How to detect the early fail through serial console? like detecting the failure during kernel booting stage also before running init or getting the shell. I think this will be a job issued by the dispatcher though I don't know how this checking mechanism will be done. Would there be anything here needed to do specifically for Android? How to connect the devices in the farm? I checked the wiki page, Platform/Validation/Specs/HardwareSetup [1]. The network will be used. I am thinking what's needed for setting up a network environment for this? The device is needed to fetch a fixed ip by dhcp just after booting up? USB gadget is an alternative for Android and in most situation could be more convenient for personal testing. adb (Android Debug Bridge, running on host side) can connect to a device through USB or TCP/IP. I suppose there are device context for describing how to connect certain device probably, like Android devices. Regarding to remote device registration, adb can list all the attached device but we still need a way to distinguish from each device in the farm. IP is a way to distinguish between each of them, like: $ adb devices List of devices attached emulator-5554 device 192.168.85.102:5555 device Any feedback is appreciated. Thanks.
