of_mdio: move of_mdio_parse_addr to header file

2017-06-13T18:00:16+00:00

The of_mdio_parse_addr() helper function is useful to other code, but the module dependency chain causes issues. To work around this, we can move of_mdio_parse_addr() to be an inline function in the header file. This gets rid of the dependencies and still allows for the reuse of code.

of_mdio: Correct check against CONFIG_OF

2017-03-24T19:51:04+00:00

CONFIG_OF_MDIO is actually what triggers the build of drivers/of/of_mdio.c, so providing inline stubs when CONFIG_OF_MDIO=y should be based on that symbol as well. Signed-off-by: Florian Fainelli Signed-off-by: David S. Miller

of_mdio: add helper to deregister fixed-link PHYs

Add helper to deregister fixed-link PHYs registered using of_phy_register_fixed_link(). Convert the two drivers that care to deregister their fixed-link PHYs to use the new helper, but note that most drivers currently fail to do so. Signed-off-by: Johan Hovold Signed-off-by: David S. Miller

of_mdio: select fixed phy support unconditionally

2016-06-28T09:47:52+00:00

Calling the fixed-phy functions when CONFIG_FIXED_PHY=m as a previous change tried cannot work if the caller is in built-in code: drivers/of/built-in.o: In function `of_phy_register_fixed_link': of_reserved_mem.c:(.text+0x85e0): undefined reference to `fixed_phy_register' Making of_mdio depend on 'FIXED_PHY || !FIXED_PHY' would solve this dependency by enforcing that OF_MDIO itself becomes a loadable module when FIXED_PHY=y, but that creates a different dependency as it breaks any built-in ethernet driver that uses of_mdio. Making FIXED_PHY a bool option also cannot work, since it depends on PHYLIB, which again is tristate. This version now uses 'select FIXED_PHY' to ensure that the fixed-phy portion of of_mdio is not optional. The main downside of this is a small increase in code size for cases that do not need fixed phy support, but it should avoid all of the link-time problems.
