2012-08-10ARM: davinci: remove broken ntosd2_init_i2cArnd Bergmann
ntosd2_init_i2c walks the ntosd2_i2c_info array, which it expects to be populated with at least one member. gcc correctly warns about the out-of-bounds access here. Since this can not possibly work, it's better to disable i2c support entirely on this board.

exynos_pm_add_dev_to_genpd is used if one or more out of a large number of Kconfig symbols are enabled. However the new exynos_defconfig selects none of those, so the function becomes unused.

2012-08-09Input: eeti_ts: pass gpio value instead of IRQArnd Bergmann
The EETI touchscreen asserts its IRQ line as soon as it has data in its internal buffers. The line is automatically deasserted once all data has been read via I2C. Hence, the driver has to monitor the GPIO line and cannot simply rely on the interrupt handler reception. In the current implementation of the driver, irq_to_gpio() is used to determine the GPIO number from the i2c_client's IRQ value. As irq_to_gpio() is not available on all platforms, this patch changes this and makes the driver ignore the passed in IRQ. Instead, a GPIO is added to the platform_data struct and gpio_to_irq is used to derive the IRQ from that GPIO. If this fails, bail out. The driver is only able to work in environments where the touchscreen GPIO can be mapped to an IRQ. Without this patch, building raumfeld_defconfig results in: drivers/input/touchscreen/eeti_ts.c: In function 'eeti_ts_irq_active': drivers/input/touchscreen/eeti_ts.c:65:2: error: implicit declaration of function 'irq_to_gpio' [-Werror=implicit-function-declaration] Signed-off-by: Daniel Mack <zonque@gmail.com> Signed-off-by: Arnd Bergmann <arnd@arndb.de> Cc: stable@vger.kernel.org (v3.2+) Cc: Dmitry Torokhov <dmitry.torokhov@gmail.com> Cc: Sven Neumann <s.neumann@raumfeld.com> Cc: linux-input@vger.kernel.org Cc: Haojian Zhuang <haojian.zhuang@gmail.com>
2012-08-09ARM: tegra: more regulator fixes for HarmonyStephen Warren
Commit 3d55c29 "ARM: tegra: harmony: add regulator supply name and its input supply" was supposed to fix all the problems with regulators on Harmony. However, it appears that I only tested it when booting using board files, not when booting using device tree. This change fixes two problems with regulators when booting using device tree: 1) That patch only created the vdd_sys regulator when booting using a board file. Since this is the root of the whole regulator tree, this caused no regulators to successfully initialize when booting using device tree. The registration of vdd_sys is moved to fix this. 2) When booting use DT, the regulator core sets has_full_constraints, which in turn causes the core to turn off any regulators not marked as always on. Some of the affected regulators are required for basic system operation. To solve this, add always on constraints to all relevant regulators. This doesn't affect booting using a board file since nothing sets has_full_constraints in that case. Signed-off-by: Stephen Warren <swarren@nvidia.com> Signed-off-by: Arnd Bergmann <arnd@arndb.de>

2012-08-08s390/compat: fix mmap compat system callsHeiko Carstens
The native 31 bit and the compat behaviour for the mmap system calls differ: In native 31 bit mode the passed in address for the mmap system call will be unmodified passed to sys_mmap_pgoff(). In compat mode however the passed in address will be modified with compat_ptr() which masks out the most significant bit. The result is that in native 31 bit mode each mmap request (with MAP_FIXED) will fail where the most significat bit is set, while in compat mode it may succeed. This odd behaviour was introduced with d3815898 "[S390] mmap: add missing compat_ptr conversion to both mmap compat syscalls". To restore a consistent behaviour accross native and compat mode this patch functionally reverts the above mentioned commit.

2012-08-04ARM: mxs: Remove MMAP_MIN_ADDR setting from mxs_defconfigMarek Vasut
The CONFIG_DEFAULT_MMAP_MIN_ADDR was set to 65536 in mxs_defconfig, this caused severe breakage of userland applications since the upper limit for ARM is 32768. By default CONFIG_DEFAULT_MMAP_MIN_ADDR is set to 4096 and can also be changed via /proc/sys/vm/mmap_min_addr if needed. Quoting Russell King [1]: "4096 is also fine for ARM too. There's not much point in having defconfigs change it - that would just be pure noise in the config files." the CONFIG_DEFAULT_MMAP_MIN_ADDR can be removed from the defconfig altogether. This problem was introduced by commit cde7c41 (ARM: configs: add defconfig for mach-mxs).

Commit 88cde8b (ARM: dts: imx: update #interrupt-cells for gpio nodes) changes gpio #interrupt-cells from 1 to 2 without updating the users. It causes the gpio irq requesting call failing in client driver's probe function. Add the irq type cell for those gpio interrupt users to fix their driver probe failure.

2012-08-03ARM: imx: enable emi_slow_gate clock for imx5Shawn Guo
The imx5 common clock migration causes a regression with smsc911x driver on imx53-ard board, where a smsc lan9220 controller gets connected on imx53 with EIM interface. EIM needs clock emi_slow_gate to be functional. In the new imx5 clock driver, there is no use count incremented for the clock by enabling it, so the framework closes the clock at late init time and makes EIM stop working then. Enable emi_slow_gate in clock driver initialization to fix the regression. Cc: stable@vger.kernel.org Signed-off-by: Shawn Guo <shawn.guo@linaro.org> Acked-by: Sascha Hauer <s.hauer@pengutronix.de>

So it just got merged, and we got this staged branch that enables the coupled cpuidle code on OMAP. With a stable git workflow from the other maintainer we could have staged this earlier, but that wasn't the case so we have had to merge it late. The alternative is to hold it off until 3.7 but given that the code is well-isolated to OMAP and they are eager to see it go in, I didn't push back hard in that direction." * tag 'pm2' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: ARM: OMAP4: CPUidle: Open broadcast clock-event device.
