changes v3:
- add Reviewed-by: Abel Vesa <abel.vesa@xxxxxxxxxx>
- rebase on top of abelvesa/for-next
changes v2:
- remove "ARM: imx6q: use of_clk_get_by_name() instead of_clk_get() to
get ptp clock" patch
- fix build warnings
- add "Acked-by: Lee Jones <lee@xxxxxxxxxx>"
- reword some commits as suggested by Fabio
Most of i.MX SoC variants have configurable FEC/Ethernet reference
lock
used by RMII specification. This functionality is located in the
general purpose registers (GRPx) and till now was not implemented as
part of SoC clock tree.
With this patch set, we move forward and add this missing functionality
to some of i.MX clk drivers. So, we will be able to configure clock
opology
by using devicetree and be able to troubleshoot clock dependencies
by using clk_summary etc.
Currently implemented and tested i.MX6Q, i.MX6DL and i.MX6UL variants.
