From: Matt Ranostay <mranostay@xxxxxx> Add dt node for the single instance of WIZ (SERDES wrapper) and SERDES module shared by PCIe, eDP and USB. Signed-off-by: Matt Ranostay <mranostay@xxxxxx> Signed-off-by: Ravi Gunasekaran <r-gunasekaran@xxxxxx> --- I had reviewed this patch in the v7 series [0]. Since I'm taking over upstreaming this series, I removed the self Reviewed-by tag. [0] - https://lore.kernel.org/lkml/4173e0c6-61d9-5b79-44ec-317870de070b@xxxxxx/ Changes from v12: * Disabled only nodes that need additional info Changes from v11: * Cleaned up comments Changes from v10: * Fixed dtbs warnings by adding "reg" property to the mux-controller nodes * Documented the reason for disabling the nodes by default * Removed Link tag from commit message Changes from v9: * Disabled serdes related nodes by default in common DT file Changes from v8: * No change Changes from v7: * Updated mux-controller node name Changes from v6: * Fixed the incorrect "compatible" property Changes from v5: * Removed Cc tag from commit message Changes from v4: * No change Changes from v3: * No change Changes from v2: * Reworked SERDES + WIZ enablement patchset to use properies for clocks defines versus entire devicetree nodes. Results in cleaner code that doesn't break dt-schema or the driver functionality.
