This adds serdes support to the LS1088ARDB. I have tested the QSGMII ports as well as the two 10G ports. The SFP slot is now fully supported, instead of being modeled as a fixed-link. Linux hangs around when the serdes is initialized if the si5341 is enabled with the in-tree driver, so I have modeled it as a two fixed clocks instead. There are a few registers in the QIXIS FPGA which control the SFP GPIOs; I have modeled them as discrete GPIO controllers for now. I never saw the AQR105 interrupt fire; not sure what was going on, but I have removed it to force polling. The MC firmware needs to be fairly new (it must support DPAA2_MAC_FEATURE_PROTOCOL_CHANGE), and the DPC needs to set the macs to MAC_LINK_TYPE_BACKPLANE. This will break ethernet if those features are not enabled. I am not sure what the upstreaming plan should be. Signed-off-by: Sean Anderson <sean.anderson@seco.com> --- Changes in v8: - Rename serdes phy handles like the LS1046A - Add SFP slot binding - Fix incorrect lane ordering (it's backwards on the LS1088A just like it is in the LS1046A). - Fix duplicated lane 2 (it should have been lane 3). - Fix incorrectly-documented value for XFI1. - Remove interrupt for aquantia phy. It never fired for whatever reason, preventing the link from coming up. - Add GPIOs for QIXIS FPGA. - Enable MAC1 PCS - Remove si5341 binding Changes in v4: - Convert to new bindings .../boot/dts/freescale/fsl-ls1088a-rdb.dts | 168 +++++++++++++++++- 1 file changed, 166 insertions(+), 2 deletions(-)
