Re: [U-Boot] [PATCH v2 41/56] rockchip: clk: rk3368: add support for GMAC (SLCK_MAC) clock

On 26 July 2017 at 04:40, Philipp Tomsich philipp.tomsich@theobroma-systems.com wrote:

To enable the GMAC on the RK3368, we need to set up the clocking appropriately to generate a tx_clk for the MAC.

This adds an implementation that implements the use of the <&ext_gmac> clock (i.e. an external 125MHz clock for RGMII provided by the PHY). This is the clock setup used by the boards currently supported by U-Boot (i.e. Geekbox, Sheep and RK3368-uQ7).

This includes the change from commit

• rockchip: clk: rk3368: define GMAC_MUX_SEL_EXTCLK
