Specify the default mux and divider clocks in device tree to ensure the FIMC devices on Trats, Trats2, Universal_c210 and Odroid X2/U3 boards are clocked from recommended clock source and with maximum supported frequency. For Trats2 also the MIPI-CSIS and the camera sensor clocks are configured, the 'clock-frequency' property is deprecated in favour of 'assigned-clock-rates' property. Signed-off-by:

Recent patch by Tomasz Figa ("irqchip: gic: Fix core ID calculation when topology is read from DT") fixed GIC driver to filter cluster ID from values returned by cpu_logical_map() for SoCs having registers mapped without per-CPU banking making it is possible to add CPU nodes for Exynos4 SoCs. In case of Exynos SoCs these CPU nodes are also required by future changes adding initialization of cpuidle states in Exynos cpuidle driver through DT. Tested on Origen board (Exynos4210 SoC) and Trats2 (Exynos4412 SoC). Signed-off-by: -

The MAX77693 is a companion power management IC for smart phones and tablets. The MAX77693 contains input over-voltage protection (OVP), a fully-integrated 2.5A switching charger for Lithium Ion battery with integrated battery disconnect, OTG/accessory 5V output power, a high-current white LED driver for camera flash, two safeout LDOs, a haptic motor driver, Model Gauge m3 battery fuel gauge and MicroUSB Interface Controller (MUIC). I2C serial interface is used for communicating. Add MAX77693 node to the Trats2 board. This allows using: - charger regulator, - 2 safeout LDO regulators (for USB OTG), - extcon. Signed-off-by:

This patch adds a convenient macro which constructs an Exynos pinctrl pinconf node containing properties needed to configure sleep state of given pin with given parameters.

In MAX77686 PMIC two regulators dedicated for eMMC memory can be controlled both by I2C interface and a GPIO pin, with the resulting regulator state being a logical OR of both. Since the GPIO control is used both by the kernel and the lowest level bootloader at reset, the regulator should be disabled by I2C control to allow it to be turned off by GPIO control. This patch removes regulator-always-on properties from both regulators and, while at it, also unsupported regulator-mem-off. Signed-off-by:

Pull audit updates from Eric Paris: "So this change across a whole bunch of arches really solves one basic problem. We want to audit when seccomp is killing a process. seccomp hooks in before the audit syscall entry code. audit_syscall_entry took as an argument the arch of the given syscall. Since the arch is part of what makes a syscall number meaningful it's an important part of the record, but it isn't available when seccomp shoots the syscall... For most arch's we have a better way to get the arch (syscall_get_arch) So the solution was two fold: Implement syscall_get_arch() everywhere there is audit which didn't have it. Use syscall_get_arch() in the seccomp audit code. Having syscall_get_arch() everywhere meant it was a useless flag on the stack and we could get rid of it for the typical syscall entry. The other changes inside the audit system aren't grand, fixed some records that had invalid spaces. Better locking around the task comm field. Removing some dead functions and structs. Make some things static.
