This commit back ports the DPLL related commits from the upstream kernel that are identified by Intel to provide the expected SyncE/GNSS functionality. There are totally 46 back ported commits included the four commits I added are used to resolve the conflicts during back porting. The 0046 patch is cherry picked from kernel-6.9. The 0031-0045 patches are cherry picked from kernel-6.8. The 0001-0030 patches are cherry picked from kernel-6.7. We also change the in-tree ice driver version to 6.6.40-stx.2 from 6.6.40-stx.1. * To fix the conflict of 91e43ca0090b ("ice: fix linking when CONFIG_PTP_1588_CLOCK=n"), we cherry pick 12a5a28b565b ("ice: remove ICE_F_PTP_EXTTS feature flag") and 89776a6a702e ("ice: check netlist before enabling ICE_F_GNSS"). Adjust 12a5a28b565b because 0d1b22367ec2 ("ice: fix pin assignment for E810-T without SMA control") already included the part code of 12a5a28b565b. https://git.yoctoproject.org/linux-yocto/commit/?id=0d1b22367ec2 * Cherry pick 7049fd5df7 ("netlink: specs: remove redundant type keys from attributes in subsets") to fix the the conflict of c3c6ab95c397 ("dpll: spec: add support for pin-dpll signal phase offset/adjust.") * Cherry pick be16574609f1 ("ice: introduce hw->phy_model for handling PTP PHY differences") to fix the confilict of 6db5f2cd9ebb ("ice: dpll:fix output pin capabilities"). Verification: - Build kernel and out of tree modules success for rt and std. - Install success onto a All-in-One lab with rt kernel. - Boot up successfully in the lab. - interfaces are up and pass packets for rt and std. - Check dmesg to see DDP package is loaded successfully and the version is 1.3.36.0 for rt and std, that is same with the OOT ice-1.14.9 driver. - The SyncE/GNSS functionality tests were done by the network team.
