[PATCH net-next v2 0/3] ave: fix the activation issues for some UniPhier SoCs

[Kunihiko Hayashi]

This add the following stuffs to fix the activation issues and satisfy
requirements for AVE ethernet driver implemented on some UniPhier SoCs.

- Add support for additional necessary clocks and resets, because the kernel
  is stalled on Pro4 due to lack of them.

- Check whether the SoC supports the specified phy-mode

- Add DT property support indicating system controller that has the feature
  for configurating phy-mode including built-in phy on LD11.

v1: https://www.spinics.net/lists/netdev/msg494904.html

Changes since v1:
- Add 'Reviewed-by' lines

Kunihiko Hayashi (3):
  net: ethernet: ave: add multiple clocks and resets support as required
    property
  dt-bindings: net: ave: add syscon-phy-mode property to configure
    phy-mode setting
  net: ethernet: ave: add support for phy-mode setting of system

[PATCH net-next v2 1/3] net: ethernet: ave: add multiple clocks and resets support as required property

[Kunihiko Hayashi]

When the link is becoming up for Pro4 SoC, the kernel is stalled
due to some missing clocks and resets.

The AVE block for Pro4 is connected to the GIO bus in the SoC.
Without its clock/reset, the access to the AVE register makes the
system stall.

In the same way, another MAC clock for Giga-bit Connection and
the PHY clock are also required for Pro4 to activate the Giga-bit feature
and to recognize the PHY.

To satisfy these requirements, this patch adds support for multiple clocks
and resets, and adds the clock-names and reset-names to the binding because
we need to distinguish clock/reset for the AVE main block and the others.

Also, make the resets a required property. Currently, "reset is
optional" relies on that the bootloader or firmware has deasserted
the reset before booting the kernel.  Drivers should work without
such expectation.

[PATCH net-next v2 3/3] net: ethernet: ave: add support for phy-mode setting of system controller

[Kunihiko Hayashi]

This patch adds support for specifying system controller that configures
phy-mode setting.

According to the DT property "phy-mode", it's necessary to configure the
controller, which is used to choose the settings of the MAC suitable,
for example, mdio pin connections, internal clocks, and so on.

Supported phy-modes are SoC-dependent. The driver allows phy-mode to set
"internal" if the SoC has a built-in PHY, and {"mii", "rmii", "rgmii"}
if the SoC supports each mode. So we have to check whether the phy-mode
is valid or not.

This adds the following features for each SoC:
- check whether the SoC supports the specified phy-mode
- configure the controller accroding to phy-mode

The DT property accepts one argument to distinguish them for multiple MAC
instances.

ethernet@65000000 {
	...
	socionext,syscon-phy-mode = <&soc_glue 0>;
};

ethernet@65200000 {
	...
	socionext,syscon-phy-mode = <&soc_glue 1>;
};
