Signed-off-by: Haiyue Wang <haiyue.w...@linux.intel.com> --- Hi Joel & Andrew, The kcs-bmc-aspeed module has been in: https://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git/tree/drivers/char/ipmi/kcs_bmc_aspeed.c https://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git/tree/Documentation/devicetree/bindings/ipmi/aspeed-kcs-bmc.txt I updated the device tree node about kcs-bmc, this is passed on my board. And the patch is generated by rebasing on: https://git.kernel.org/pub/scm/linux/kernel/git/joel/aspeed.git Please help to review.
