2017-06-06arm: dts: am33xx: Remove redundant interrupt-parent propertySuniel Mahesh1-6/+0
Interrupt-parent property is defined in the root node as "interrupt-parent = <&intc>". This interrupt-parent value becomes the default for the system, so removed redundant "interrupt-parent" property from mmc, mac, lcdc and tscadc nodes.

2017-06-06ARM: dts: AM43XX: Remove min and max voltage values for dcdc3Keerthy3-6/+0
dcdc3 supplies to DDR on AM43x series. When we set both min and max values to the same value. The regulator framework sets that particular voltage. This is bad as we are changing the ddr voltage when executing from ddr. Hence remove the min and max values. The ddr supply voltage shall be set from bootloader when not executing from ddr and not while executing from kernel.

2017-06-06ARM: dts: twl4030: Add missing madc reference for bci subnodeMarek Belisko1-0/+2
The twl4030_charger driver expects an iio channel to detect the presence of an AC charger by looking at VAC (madc channel 11). This definition is missing in the device tree.

2017-06-02ARM: dts: rockchip: enable usb for rk3229 evb boardWilliam Wu1-0/+74
Rockchip's rk3229 evaluation board has one usb otg controller and three usb host controllers. Each usb controller connect with one usb2 phy port through UTMI+ interface. And the three usb host interfaces use the same GPIO VBUS drive. Let's enable them to support usb on rk3229 evb board.

2017-06-01ARM: dts: augment Moxa and Aspeed DTS for FTTMR010Linus Walleij3-9/+8
This augments the Moxa Art and Aspeed device trees to: - Explicitly name the clock "PCLK" as the Faraday FTTMR010 names it. - List the Moxa timer as compatible with the Faradat FTTMR010 vanilla version. - Add a comment that the Aspeed driver is a Faraday FTTMR010 derivative. - Pass all IRQs to the timer from Aspeed: they are all there so they should be in the device tree, we only use the first one anyways.

2017-05-30ARM: dts: da850: Add interrupt-controller property to gpio nodeKeerthy1-0/+2
The gpio node has 144 gpios. Each gpio is capable of generating an interrupt. Hence add interrupt-controller property to the gpio node. With this in place one can use interrupts property in device tree to request for the gpio interrupts. Signed-off-by: Keerthy <j-keerthy@ti.com> Signed-off-by: Sekhar Nori <nsekhar@ti.com>

2017-05-26x86/ftrace: Make sure that ftrace trampolines are not RWXThomas Gleixner1-6/+14
ftrace use module_alloc() to allocate trampoline pages. The mapping of module_alloc() is RWX, which makes sense as the memory is written to right after allocation. But nothing makes these pages RO after writing to them. Add proper set_memory_rw/ro() calls to protect the trampolines after modification.

It is also fine to leave interrupts enabled during this time as there's only one CPU running, and on_each_cpu() means to only run on the current CPU. If early_boot_irqs_disabled is set, it is safe to run cpu_flush_range() with interrupts disabled. Don't trigger a BUG_ON() in that case.
