The first four patches address GMAC clock parents. On these boards the DTS lists SCLK_GMACx in assigned-clocks but only provides a parent for SCLK_GMACx_RX_TX, so SCLK_GMACx keeps whatever parent the bootloader or the hardware reset left. Add CLK_MACx_2TOP explicitly so the GMAC main clock always comes from the internal source. BPI-R2 Pro additionally describes clock_in_out wrongly ("input" while the port is a fixed-link with no external 125 MHz clock); switch it to "output" to match the hardware. On RK3568 clock_in_out does not change the hardware clock routing today, so that part is a description fix. The last patch fixes USB OTG power on the Ariaboard Photonicat. On battery power the USB port is dead because usb2phy0_otg is fed from a regulator that only exists when the DC input is present. Add a boost regulator gated by the existing vcc5v0_usb30_otg0 rail and switch the PHY supply to it, restoring USB host functionality on battery. --- Coia Prant (5): arm64: dts: rockchip: fix GMAC clock parents on 9Tripod X3568 v4 arm64: dts: rockchip: fix GMAC clock parents on Graperain G3568 v2 arm64: dts: rockchip: fix GMAC clock setup on BPI-R2 Pro arm64: dts: rockchip: fix GMAC clock parent on Photonicat arm64: dts: rockchip: fix USB OTG power on Photonicat in battery mode .../dts/rockchip/rk3568-9tripod-x3568-v4.dts | 4 ++-- .../boot/dts/rockchip/rk3568-bpi-r2-pro.dts | 4 +++- .../rockchip/rk3568-graperain-g3568-v2.dts | 4 ++-- .../boot/dts/rockchip/rk3568-photonicat.dts | 21 +++++++++++++++++-- 4 files changed, 26 insertions(+), 7 deletions(-) -- 2.47.3
