[PATCH v1 00/10] provide ethernet support for ar9344 and TP-LINK TL-WDR4300

[Oleksij Rempel]

This patches should go on top of my previous set "[PATCH v1 1/3] net: ath79: add ag71xx Ethernet driver"
It is enabling networking support for ar9344 on TP-LINK TL-WDR4300 router.

Oleksij Rempel (10):
  net: ath79: add ar9344 support
  MIPS: dts: ar9331: update compatible for mac0 node
  MIPS: dts: ar9344: add mac0 node
  MIPS: dts: tl_wdr4300: enable mac0
  MIPS: dts: tl_wdr4300: add alias for spiflash
  MIPS: dts: tl_wdr4300: remove RO flag from barebox partition
  add phy: ar8327 driver
  rename tplink devicetree
  MIPS: tplink-wdr4300_defconfig: add network support
  MIPS: dts: ar9344: add APB bus

The 'volatile' looks rather unnecessary.

lowercase letters for hex numbers please.

This is a loop counter, no need to specify the width of the variable,
plain 'int' looks better here.

Please use dev_err when printing device specific messages.

Shouldn't you return an error here instead of continuing?

Port %d of what device?? dev_* functions really make it easy to add
helpful context to such messages.

s/versio/version/. Also the usual printk/dev_* beefing. It would be nice
