[PATCH net-next 01/10] dt-bindings: doc: net: keystone-netcp: document cpts

The Keystone 2 66AK2HK/E/L 1G Ethernet Switch Subsystems contains The Common Platform Time Sync (CPTS) module which is in general compatible with CPTS module found on TI AM3/4/5 SoCs. So, the basic support for Keystone 2 CPTS is available by default, but not documented. The Keystone 2 CPTS module

[PATCH net-next 02/10] net: ethernet: ti: cpts: use devm_get_clk_from_child

Use devm_get_clk_from_child() instead of devm_clk_get() and this way allow to group CPTS DT properties in sub-node for better code readability and maintenance. Roll-back to devm_clk_get() if devm_get_clk_from_child() fails for backward compatibility. Signed-off-by: Grygorii Strashko ---
