[U-Boot] [PATCH v4 1/7] arch: arm: mach-rockchip: rk3288: Enable regulators in board_init

[Janine Hagemann]

Use regulators_enable_boot_on() to init all the regulators with
regulator-boot-on property. This is relevant for all rk3288-boards.

[U-Boot] [PATCH v4 3/7] drivers: net: designware: Add reading of DT phy-handle node

[Janine Hagemann]

Add the ability to read the phy-handle node of the
gmac.  Upon reading this handle the phy-id
can be stored based on the reg node in the DT.

The phy-handle also needs to be stored and passed
to the phy to access any phy data that is available.

which is 25 MHz. Set CLK_O_SEL to channel A transmit
clock so we have 125 MHz on CLK_OUT.

[U-Boot] [PATCH v4 6/7] net: gmac_rockchip: Fix a register write in rk3328_gmac_set_to_rgmii

[Janine Hagemann]

We have to use RK3328_RXCLK_DLY_ENA_GMAC_ENABLE instead of
RK3328_RXCLK_DLY_ENA_GMAC_MASK in rk3328_gmac_set_to_rgmii()
to enable the RX delay.
The MASK was used in a wrong way.

[U-Boot] [PATCH v4 7/7] net: gmac_rockchip: Add handeling for RGMII_ID/RXID/TXID

[Janine Hagemann]

Using PHY internal delays in combination with the phy-mode
rgmii-id/rxid/txid was not possible. Only rgmii was supported.

Now we can disable rockchip's gmac delay lines and also use
rgmii-id/rxid/txid.

Based on commit eaf70ad14cbb ("net: stmmac: dwmac-rk: Add
handling for RGMII_ID/RXID/TXID") for mainline linux kernel.
