2015-12-22ARM: dts: TS-4800: add basic device treeDamien Riegel
This device tree adds support for TS-4800 by Technologic Systems. This board is based on MX51-babbage, but there are some subtle differences in the pins used, and there is an additional FPGA that is memory-mapped.

2015-12-22ARM: dts: imx: ventana: Allow HDMI and LVDS to work simultaneouslyTim Harvey
Currently it is not possible to have HDMI and LVDS working simultaneously, because both ports try to use PLL5. Move the LVDS clock parent to PLL3_USB_OTG, so that HDMI and LVDS can be driven from independent sources.

2015-12-22ARM: 8482/1: l2x0: make it possible to disable outer sync from DTLinus Walleij
According to commit 2503a5ecd86c002506001eba432c524ea009fe7f "ARM: 6201/1: RealView: Do not use outer_sync() on ARM11MPCore boards with L220" Some PB11MPCore RealView core tiles have broken outer_sync. We got rid of the custom barriers from the machine by disabling outer sync, but that was just for the boardfile case. We have to be able to do the same in the device tree case. Since __l2c_init() is cloning and copying the L2C vtable, we pass an argument to this function to optionally numb the outer sync operation if desired, before initializing the cache. After this we can set up the cache correctly on the RealView PB11MPCore. This was tested on a PB11MPCore known to have the issue. Before this, spurious crashes would occur if we try to set up the cache properly, after this it boots rock solid.

2015-12-22ARM: 8488/1: Make IPI_CPU_BACKTRACE a "non-secure" SGIMarc Zyngier
Having IPI_CPU_BACKTRACE as SGI15 may not work if the kernel is running in non-secure mode and that the secure firmware has decided to follow ARM's recommendations that SGI8-15 should be reserved for secure purpose. Now that we are "only" using SGI0-6, change IPI_CPU_BACKTRACE to use SGI7, which makes it more likely to work.

2015-12-22ARM: 8487/1: Remove IPI_CALL_FUNC_SINGLEMarc Zyngier
Since 9a46ad6d6df3 ("smp: make smp_call_function_many() use logic similar to smp_call_function_single()"), the core IPI handling has been simplified, and generic_smp_call_function_interrupt is now the same as generic_smp_call_function_single_interrupt. This means that one of IPI_CALL_FUNC and IPI_CALL_FUNC_SINGLE has become redundant. We can then safely drop IPI_CALL_FUNC_SINGLE, and use only IPI_CALL_FUNC. This has the advantage of reducing the number of SGI IDs we're using (a fairly scarse resource). Tested on a dual A7 board.

2015-12-22ARM: 8485/1: cpuidle: remove cpu parameter from the cpuidle_ops suspend hookLorenzo Pieralisi
The suspend() hook in the cpuidle_ops struct is always called on the cpu entering idle, which means that the cpu parameter passed to the suspend hook always corresponds to the local cpu, making it somewhat redundant. This patch removes the logical cpu parameter from the ARM cpuidle_ops.suspend hook and updates all the existing kernel implementations to reflect this change.

The Empire Electronix D709 tablet is a fairly standard 7" A13 tablet, featuring usb-wifi, a micro-sd slot, micro-usb otg and headphone jack. Empire Electronix is written on the back of the tablet, the D709 model info can be found in the about tablet menu in android. The PCB has no markings to speak of. This dts file does not add support for the ft5x touchscreen found at i2c bus 1, addr 0x38, irq PG11, because it does not work out of the box. It seems it has been flashed with the wrong firmware and needs to have alternative firmware uploaded at boot to make the touchscreen work properly, when hot-booting from android into an upstream kernel the touchscreen does work. The Memsic MXC622X accelerometer at i2c bus 1, addr 0x15 also is not enabled as there is no driver for it.
