[PATCH V3 02/10] tty: serial: bcm63xx: Add support for unnamed clock outputs from DT

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



The original non-DT bcm63xx clk code ignores the struct device argument
and looks up a global clock name.  DT platforms, by contrast, often just
use a phandle to reference a clock node with no "clock-output-names"
property.  Modify the UART driver to support both schemes.
