Julien Dusser 87627b2d76 ath79: add QCA956x SERDES init workaround ... This commit add a workaround for non working SGMII link observed on some QCA956x SoCs. The workaround originates part from the U-Boot source code from QCA, part from the implementation from TP-Link found in the GPL tarball for the EAP245v1. Extends commit 0d416a8d3b for QCA956x. Note that reset is the same on QCA955x and QCA956x, same register offset and values. Auto calibration is done on u-boot, but always fall back to default value 0x7. Add a DTS entry serdes-cal in case a device require another value.
