Support the remote devices on the remote processor via the RPMSG bus on
i.MX platform.
Changes in v3:
- fix various format issue and return value check per Peng 's review
comments.
- add the logic to also populate the subnodes which are not in the
device map per Arnaud's request. (in imx_rproc.c)
- update the yaml per Frank's review comments.
Changes in v2:
- re-implemented the gpio driver per Linus Walleij's feedback by using
GPIOLIB_IRQCHIP helper library.
- fix various format issue per Mathieu/Peng 's review comments.
- update the yaml doc per Rob's feedback
