Subject: [PATCH 15/30] net: dsa: mt7530: call port 6 setup from
|
|||
|
|
mt7530_mac_config()

mt7530_pad_clk_setup() is called if port 6 is enabled. It used to do more
|
|||
|
|
things than setting up port 6. That part was moved to more appropriate
|
|||
|
|
locations, mt7530_setup() and mt7530_pll_setup().
|
|||
|
|
|
|||
|
|
Now that all it does is set up port 6, rename it to mt7530_setup_port6(),
|
|||
|
|
and move it to a more appropriate location, under mt7530_mac_config().
|
|||
|
|
|
|||
|
|
Change mt7530_setup_port6() to void as there're no error cases.
|
|||
|
|
|
|||
|
|
Leave an empty mt7530_pad_clk_setup() to satisfy the pad_setup function
|
|||
|
|
pointer.
|
|||
|
|
|
|||
|
|
This is the code path for setting up the ports before:
|
|||
|
|
|
|||
|
|
dsa_switch_ops :: phylink_mac_config() -> mt753x_phylink_mac_config()
|
|||
|
|
-> mt753x_mac_config()
|
|||
|
|
-> mt753x_info :: mac_port_config() -> mt7530_mac_config()
|
|||
|
|
-> mt7530_setup_port5()
|
|||
|
|
-> mt753x_pad_setup()
|
|||
|
|
-> mt753x_info :: pad_setup() -> mt7530_pad_clk_setup()
|
|||
|
|
|
|||
|
|
This is after:
|
|||
|
|
|
|||
|
|
dsa_switch_ops :: phylink_mac_config() -> mt753x_phylink_mac_config()
|
|||
|
|
-> mt753x_mac_config()
|
|||
|
|
-> mt753x_info :: mac_port_config() -> mt7530_mac_config()
|
|||
|
|
-> mt7530_setup_port5()
|
|||
|
|
-> mt7530_setup_port6()
