Message-ID<qCZbA-1Xo-13@gated-at.bofh.it>
this patchset fixes the bug that eth can't initial successful on hip05-D02
because the dts files doesn't match the source code.

yankejian (2):
  dts: hisi: fixes no syscon error when init mdio
  net: hns: fixes no syscon error when init mdio

change log:
v2:
 1) update the related documented in the binding as well
 2) use the normal naming conventions using '-' instead of '_', and
    update the related *.c files.

#1285078 — [PATCH v2 next 1/2] dts: hisi: fixes no syscon error when init mdio

Subject[PATCH v2 next 1/2] dts: hisi: fixes no syscon error when init mdio
Message-ID<qCZlf-20I-15@gated-at.bofh.it>
In reply to#1285077
Signed-nux start up, we get the log below:
"Hi-HNS_MDIO 803c0000.mdio: no syscon hisilicon,peri-c-subctrl
 mdio_bus mdio@803c0000: mdio sys ctl reg has not maped       "

the source code about the subctrl is dealled with syscon, but dts doesn't.
it cause such fault. so this patch adds the syscon info on dts files to
fixes it. and it adds documentation for the devicetree bindings used by
DT files of Hisilicon Hip05-D02 development board.
