[PATCH linux dev-5.3 v2 0/8] ftgmac100: Support AST2600 RMII

[Andrew Jeffery]

Hello,

This series adds support for ungating RMII RCLK on the AST2500 and AST2600,
enabling use of NCSI for the MACs if u-boot does not ungate the clock for us.

The patches have not yet been sent upstream, but I intend to do so once we're
through the 5.4 merge window to avoid some of them disappearing into the
net-next void.

v2:
* Support AST2500 RCLK as well.
* Add fixed RCLK clocks and describe correct parent clocks
* Re-order the patches to group clock and net changes.
* Update all the 2500- and 2600-based devicetrees

Tested by pinging a remote host on Tacoma (2600, u-boot does not configure
RCLK) and Witherspoon (2500, manually disabled RCLK in u-boot before booting
the kernel) hardware, and used QEMU to ensure the driver probes correctly on
Palmetto (2400, no gate for RCLK).

Please review!

Andrew
