From c6433083f5930fdf52ad47c8c0459719c810dc89 Mon Sep 17 00:00:00 2001 From: Chen-Yu Tsai Date: Sun, 17 Jan 2021 18:07:08 +0800 Subject: arm64: dts: rockchip: rk3328: Add clock_in_out property to gmac2phy node The gmac2phy is integrated with the PHY within the SoC. Any properties related to this integration can be included in the .dtsi file, instead of having board dts files specify them separately. Add the clock_in_out property to specify the direction of the PHY clock. This is the minimum required to have gmac2phy working on Linux. Other examples include assigned-clocks, assigned-clock-rates, and assigned-clock-parents properties, but the hardware default plus the implementation requesting the appropriate clock rate also works.
