4 Subject: [PATCH 33/48] net: dsa: mt7530: call port 6 setup from
7 Content-Type: text/plain; charset=UTF-8
8 Content-Transfer-Encoding: 8bit
10 mt7530_pad_clk_setup() is called if port 6 is enabled. It used to do more
11 things than setting up port 6. That part was moved to more appropriate
12 locations, mt7530_setup() and mt7530_pll_setup().
14 Now that all it does is set up port 6, rename it to mt7530_setup_port6(),
15 and move it to a more appropriate location, under mt7530_mac_config().
17 Change mt7530_setup_port6() to void as there're no error cases.
19 Leave an empty mt7530_pad_clk_setup() to satisfy the pad_setup function
22 This is the code path for setting up the ports before:
24 dsa_switch_ops :: phylink_mac_config() -> mt753x_phylink_mac_config()
25 -> mt753x_mac_config()
26 -> mt753x_info :: mac_port_config() -> mt7530_mac_config()
27 -> mt7530_setup_port5()
29 -> mt753x_info :: pad_setup() -> mt7530_pad_clk_setup()
33 dsa_switch_ops :: phylink_mac_config() -> mt753x_phylink_mac_config()
34 -> mt753x_mac_config()
35 -> mt753x_info :: mac_port_config() -> mt7530_mac_config()
36 -> mt7530_setup_port5()
37 -> mt7530_setup_port6()
