Heads up: Manifest names have changed in linaro_android_2.3.5 and linaro-android-11.09-release

by Zach Pfeffer

Team, I'm modifying the builds and the manifests to use the term staging instead of LEB. All the tip builds have been switched over. I've turned off build everyday for the LEB- versions. Each of the new builds will have build everyday set. -Zach -- Zach Pfeffer Android Platform Team Lead, Linaro Platform Teams Linaro.org | Open source software for ARM SoCs Follow Linaro: http://www.facebook.com/pages/Linaro http://twitter.com/#!/linaroorg - http://www.linaro.org/linaro-blog

[Patch v3 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 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 | 7 + drivers/input/touchscreen/Makefile | 1 + drivers/input/touchscreen/da9052_tsi.c | 369 ++++++++++++++++++++++++++++++++ 3 files changed, 377 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..a5d2e7b 100644 --- a/drivers/input/touchscreen/Kconfig +++ b/drivers/input/touchscreen/Kconfig @@ -144,6 +144,13 @@ 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 + 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..0897340 --- /dev/null +++ b/drivers/input/touchscreen/da9052_tsi.c @@ -0,0 +1,369 @@ +/* + * TSI driver for Dialog DA9052 + * + * Copyright(c) 2011 Dialog Semiconductor Ltd. + * + * Author: David Dajun Chen <dchen(a)diasemi.com> + * + * This program is free software;

Improvements to kernel deb-pkg target for continuous integration

by James Westby

Hi, Here are two patches that are needed for the kernel CI effort. I would appreciate reviews on my first kernel patches to be submitted, and guidance for where to send them to get them accepted upstream. Needed in order to run the target when cross-building. Needed in order to stop jobs in the CI system from overwriting each others files. Thanks, James
