From 1bf4b15b1975f4554cb3346dc82b02f5f4a1271b Mon Sep 17 00:00:00 2001 From: Tony Lindgren Date: Tue, 17 Mar 2020 09:45:24 -0700 Subject: clk: ti: Fix dm814x clkctrl for ethernet We are missing alwon ethernet clock for dm814x and this prevents us from probing the CPSW with device tree only data. Looks like Ethernet currently only works if it has been enabled in the bootloader. Looks like relying on the bootloader clocks is not an issue with the mainline kernel currently, but it will be an issue when configuring CPSW Ethernet to probe with device tree data only as we will be managing the clocks.

Note that as we now also start using the clkctrl clock binding on dm816x, the board specific dts files must also have compatible "ti,dm816". This is needed for the clkctrl clocks to probe properly, so any out of tree dts files may need to be updated accordingly.
