[PATCH 0/3] HiSilicon LPC defconfig and DT patches

[PATCH 0/3] HiSilicon LPC defconfig and DT patches

[John Garry]

This series introduces 3 patches, to enable the
HISILICON_LPC config in the arm64 defconfig
and also add the relevant LPC DT entries.

For hip06 UART support, we depend on this patch:
https://lkml.org/lkml/2018/4/27/258

John Garry (3):
  arm64: defconfig: Enable HISILICON_LPC
  arm64: dts: hisi: Enable Hisi LPC node for hip06
  arm64: dts: hisi: Enable Hisi LPC node for hip07

[PATCH 1/3] arm64: defconfig: Enable HISILICON_LPC

[John Garry]

Now that the driver has been merged for the HiSilicon
LPC host, enable the relevant config.

Turning on this config will also enable config
INDIRECT_PIO, which would have not been enabled
previously - see config info for more details.

Series applied into the hisilicon tree.
Thanks!
