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.

2016-03-18rn5t567: register ARM reset callbackStefan Agner

2016-03-18rn5t567: do not register poweroffStefan Agner
The Colibri iMX7 uses the SNVS_PMIC_ON_REQ signal (connected to the PMIC's PMIC_ON_EXTIN GPIO) to power off the module. The SNVS RTC driver provides a poweroff callback which causes that signal to go low. However, the current PMIC driver registers a poweroff callback earlier and therefor the kernel uses the PMIC poweroff instead of the SNVS RTC poweroff callback.

2016-03-18ARM: dts: imx7d-colibri: disable power keyStefan Agner

The PIXDATA flags of the display_flags enum are controller centric, e.g. NEGEDGE means the controller shall drive the data signals on pixelclocks negative edge. However, the drivers flag is display centric: Sample the data on negative (falling) edge.

2016-03-09input: touchscreen: ad7879: fix default x/y axis assignmentStefan Agner
The measurements read from the controller which are temporarly stored in conversion_data, are interpreted wrong. The first measurement X+ contains the Y position, and the second measurement Y+ the X position (see also Table 11 Register Table in the data sheet). The problem is already known, the change 6680884a4420 ("Input: ad7879 - add option to correct xy axis") introduced a swap option. However, the meaning of this boolean was inverted since the underlaying values were already swapped. With this change, swap_xy = true actually swaps the two axis.

By configure runtime PM prior we enable the use of it, we close the gap for strange and unhandled conditions.

2016-03-08tty: serial: imx: disable DCD and RI interruptsStefan Agner
If the UART is in DTE mode, the signals DCD and RI are inputs. In this case, the control bits in UCR3_DCD and UCR3_RI control the interrupt of those two inputs. The two bits are 1 on reset, hence leading to an interrupt if one of those signal changes... However, as of now the interrupt handler does not handle these interrupts, leading to a interrupt strom. Solve the issue by explicitly disabling the two interrupts during initialization. Signed-off-by: Stefan Agner <stefan.agner@toradex.com> Acked-by: Max Krummenacher <max.krummenacher@toradex.com>
