Subject: [PATCH v3 0/9] arc_emac: fixes the emac issues and cleanup emac drivers

Hi all,
This series patches are based on kernel 4.5-rc7+ version.
Linux version 4.5.0-rc7-next-20160311+ (wxt@nb) (...) #45 SMP Sun Mar 13 16:17:56

The history patch in here:
Patch-v1: https://lkml.org/lkml/2016/3/11/209
Patch-v2: https://lkml.org/lkml/2016/3/13/39

Verified on kylin board with my github.
https://github.com/Caesar-github/rockchip/tree/kylin/next

That's verified on kylin board with ubuntu os.

This series patches are built all pass with Mr.robot on
https://github.com/Caesar-github/linux/tree/build-emac-v3

How to test and verify?

You can refer to the following wiki document.

1) This series has 6 patches: (1--->9)
net: arc_emac: make the rockchip emac document more compatible
net: arc_emac: add phy reset is optional for device tree
net: arc_emac: support the phy reset for emac driver
net: arc: trivial: cleanup the emac driver
clk: rockchip: add node-id for rk3036 emac hclk
clk: rockchip: associate the rk3036 HCLK_EMAC clock-id
clk: rockchip: add clock-id for rk3036 emac pll source clock
clk: rockchip: associate SCLK_MAC_PLL and disable reparenting on rk3036
ARM: dts: rockchip: add support emac for RK3036

2) This series patches have the following descriptions:

Hi Rob, David:
PATCH[1/9-2/9]: ====>
net: arc_emac: make the rockchip emac document more compatible
net: arc_emac: add phy reset is optional for device tree

The patches change the rockchip emac document for more compatible and
Add the phy reset property for document.
---

Hi David
PATCH[3/9]: ====>
net: arc_emac: support the phy reset for emac driver

The emac didn't work on kylin board since in some case the clocks parent changed.
The kylin hardware connects the phy reset pin, we should use it with real world.
As the previous patch discuss on https://patchwork.kernel.org/patch/8186801/

And as sergei/Heiko suggestions on
https://patchwork.kernel.org/patch/8564571/
---

Hi David
PATCH[4/9]: ====>
net: arc: trivial: cleanup the emac driver

The first time to look the emac drivers, I think that have to cleanup the drivers with scripts.
Although it's the trivial things, in order to be more read.

Hi Heiko,Michael,Stephen:
PATCH[5/9-8/9]: ====> clk: rockchip: rk3036: fix and add node id for emac clock

Four-part from https://patchwork.kernel.org/patch/8564581/
clk: rockchip: add node-id for rk3036 emac hclk
clk: rockchip: associate the rk3036 HCLK_EMAC clock-id
clk: rockchip: add clock-id for rk3036 emac pll source clock
clk: rockchip: associate SCLK_MAC_PLL and disable reparenting on rk3036

Add the emac needed clocks for rk3036 SoCs
---

Hi Heiko:
PATCH[9/9]: ====>
ARM: dts: rockchip: add support emac for RK3036

Add the emac needed main info for rk3036 dts.
---

Thanks your reviewing! :)


Changes in v3:
- %s/he/the
- Add the Cc people
- As Sergei comments, the original name is better, so
  %s/reset-gpios/phy-reset-gpios
- Add the Cc people.
- Caused the build error since the missing include head file.
- %s/reset/phy-reset to match the device tree.
- Add the Cc people
- Add the Cc people.
- Add the Cc people.
- Add the Cc people.
- Add the Cc people.
- Add the Cc people.
- rename reset-gpio to phy-reset-gpios.
- change the commit.
- remove the pcfg_output_high, that's really not needed for emac.
- Add the Cc people.
- Fixes the 'zhengxing' to 'Xing Zheng'.

Changes in v2:
- change the commit and remove the repeat the name 'rockchip'.
- %s/phy-reset-gpios/reset-gpios
- As the pervious version, Sergei and Heiko comments on
  https://patchwork.kernel.org/patch/8564571/.
- Nevermind, add signed-off since Heiko the original patch,
  refer the Heiko's test patch on
  https://github.com/mmind/linux-rockchip/commit/a943c588783438ff1c508dfa8c79f1709aa5775e
  :)
- As the robot notice the build error since overflow in implicit
  constant conversion.
- rename phy-reset-gpio to reset-gpios.
