2016-03-21ARM: disable_nonboot_cpus before poweroffColibri_iMX6_LinuxImageV2.6Beta1_20160331Apalis_iMX6_LinuxImageV2.6Beta1_20160331Stefan Agner
If poweroff takes a bit more time (e.g. due to I2C call), it is quite likely that another timer interrupt fires. Timer interrupt get broadcasted through the timer interrupt callback tick_handle_oneshot_broadcast. This code broadcasts the timer interrupt to all CPU's in tick_broadcast_oneshot_mask. The only function which removes CPU from this mask is tick_shutdown_broadcast_oneshot which ultimately get called by _cpu_down (in kernel/cpu.c). The function disable_nonboot_cpus makes sure that the CPU's get properly taken down and _cpu_down gets called. With that no more broadcasts are sent to CPU's which are no longer online.

2016-03-18ARM: dts: imx7d-colibri: disable power keyStefan Agner
Disable SNVS power key functionality by default for Colibri i.MX 7 modules. The SNVS power key uses the ONOFF signal, which is directly controlled by reset and therefor not really a power key available to the user. Signed-off-by: Stefan Agner <stefan.agner@toradex.com>

2016-03-08ARM: dts: imx: fix invalid #address-cells valueTim Harvey
The invalid value of #address-cells in the imx6 pcie host controller node causes of_irq_parse_raw() to incorrectly advance through an interrupt-map table of more than one interrupt. We also take the opportunity to drop the unused #size-cells here. This patch resolves this issue and allows proper interrupt mapping for an imx6 pcie host connected to a P2P bridge when using legacy interrupts.

2015-12-26pm-imx6.c: fix power off by stop modeMax Krummenacher
With the 3.14.28 release of the kernel imx6_stop_mode_poweroff() does not enter stop mode. Thus the function does not switch of power but returns. This seems to be caused by the second processor which has been stopped. Set the WFI event mask for the stopped processor works around the issue.
