| |
AM64 uses the same SERDES as in J7200, however AM642 EVM doesn't have a clock generator (unlike J7200 base board). Here the clock from the SERDES has to be routed to the PCIE connector. This series adds support to drive reference clock output from SERDES and also adds SERDES (torrent) and SERDES wrapper (WIZ) bindings.
v1 of the patch series can be found @ [1] v2 of the patch series can be found @ [3]
Changes from v2: *) Sent the DT bindings as a separate series [4] *) Remove enabling PHY output clock in isolation mode
Changes from v1: *) Model the internal clocks without device tree input (Add #clock-cells to SERDES DT nodes for getting a reference to the clock using index to phandle). This is in accordance with comment given by Rob [2]. However the existing method to model clocks from device tree is not removed to support upstreamed device tree. *) Included a patch to fix modifying static data by instance specific initializations. *) Added a fix to delete "clk_div_sel" clk provider during cleanup
