The "qca,clk-out-frequency" is calculated incorrectly for AR8035 due to incorrect masking of priv->clk_25m_reg and priv->clk_25m_mask.
This same issue has been already fixed in the kernel by:
commit b1f4c209d84057b6d40b939b6e4404854271d797 Author: Oleksij Rempel o.rempel@pengutronix.de Date: Wed Apr 1 11:57:32 2020 +0200
net: phy: at803x: fix clock sink configuration on ATH8030 and ATH8035
The masks in priv->clk_25m_reg and priv->clk_25m_mask are one-bits-set for the values that comprise the fields, not zero-bits-set.
This patch fixes the clock frequency configuration for ATH8030 and ATH8035 Atheros PHYs by removing the erroneous "~".
To reproduce this bug, configure the PHY with the device tree binding "qca,clk-out-frequency" and remove the machine specific PHY fixups.

Apply the same fix in the U-Boot driver.
Tested on a i.MX6 Hummingboard.
