2016-06-29can: mcp251x: fix resume when device is downColibri_iMX6_LinuxImageV2.6Beta2_20160701Apalis_iMX6_LinuxImageV2.6Beta2_20160701Stefan Agner
If a valid power regulator or a dummy regulator is used (which happens to be the case when no regulator is specified), restart_work is queued no matter whether the device was running or not at suspend time. Since work queues get initialized in the ndo_open callback, resuming leads to a NULL pointer exception. Reverse exactly the steps executed at suspend time: - Enable the power regulator in any case - Enable the transceiver regulator if the device was running, even in case we have a power regulator - Queue restart_work only in case the device was running Fixes: bf66f3736a94 ("can: mcp251x: Move to threaded interrupts instead of workqueues.")

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.

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.

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.
