- /dev/ttyMCCp0 can be created.
- use schedule delayed work to kick off the demo
- one simple test app(mxc_mcc_tty_test.out) used to do
the mcc pty interface demo tests.
- m4 part of the mcc pingpong demo is required to be run
on m4.
- up to now, only the unsigned int decimal number is used
in the tests.
test how-to by the simple test app:
./mxc_mcc_tty_test.out /dev/ttyMCCp0 115200 R 1 512 &
echo <your input> > /dev/ttyMCCp0
then
<your input + 1> would be received the test app.

- based on sema4 driver, mcc stack, add the mcc_demo driver
by sysfs.
- mcc pingpong demo
- mcc can demo
NOTE:
- rdc should be disabled in m4 mqx side, otherwise, a9 linux would
fail to mount rootfs.
- add the m4 related clks at linux side, because that the m4's clks
would be turned off/on during linux boot up if they are not added
at linux clk definitions.
