2017-01-10rpmsg: use _debug variants for print_hex_dumpStefan Agner
Using print_hex_dump_debug avoids printing of every rpmsg message which is crucial when exchanging messages in higher rates.

2017-01-10rpmsg: imx: do not push data when no reader is availableStefan Agner
Pushing data while there is no reader seems to lock/crash the TTY layer in some way.

2017-01-10hexdump: do not print debug dumps for !CONFIG_DEBUGLinus Walleij
print_hex_dump_debug() is likely supposed to be analogous to pr_debug() or dev_dbg() & friends. Currently it will adhere to dynamic debug, but will not stub out prints if CONFIG_DEBUG is not set. Let's make it do the right thing, because I am tired of having my dmesg buffer full of hex dumps on production systems.

2017-01-10ARM: imx: define buffer count per VirtIO queueStefan Agner
Let RPMSG_NUM_BUFS to be the number of buffers per VirtIO queue, so that each queue (TX/RX) has 256 buffers. The change does not affect the number of buffers. But specifing per VirtIO queue aligns better with the way buffer sizes are specified on the FreeRTOS side (in platform_info.c).

2017-01-10gpio: mxc: clear interrupt mask/status optionallyStefan Agner
Add a kernel parameter ("gpio-mxc.noclearirq") to disable unconditional interrupt mask/clearing. This is useful when a second CPU (the Cortex-M4) is accessing the same GPIO bank. Using the same GPIO bank from the Cortex-A7 and M4 sounds risky, but it seems to work quite well. Most registers are write only (e.g. interrupt status register can be cleared with a single write), which makes them safe for concurrent access. However, sharing a single GPIO bank between two cores does not allow to use the Resource Domain Controller. Hence for secure applications assigning a dedicated GPIO bank is still preferable.

2017-01-10tty: 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.
