net: phy: micrel: use generic config_init for KSZ8021/KSZ8031

2014-12-26T21:19:50+00:00

Use generic config_init callback also for KSZ8021 and KSZ8031.

This has been avoided this far due to commit b838b4aced99 ("phy/micrel:
KSZ8031RNL RMII clock reconfiguration bug"), which claims that the PHY
becomes unresponsive if the broadcast-disable flag is set before
configuring the clock mode.

Turns out that the problem seemingly worked-around by the above
mentioned commit was really due to a hardware-configuration issue, where
the PHY was in fact strapped to address 3 rather than 0.

net: phy: micrel: add support for clock-mode select to KSZ8081/KSZ8091

2014-11-21T19:08:56+00:00

Micrel KSZ8081 and KSZ8091 PHYs have the RMII Reference Clock Select
bit, which is used to select 25 or 50 MHz clock mode.

Note that on some revisions of the PHY (e.g. KSZ8081RND) the function of
this bit is inverted so that setting it enables 25 rather than 50 MHz
mode. Add a new device-tree property
"micrel,rmii-reference-clock-select-25-mhz" to describe this.

net: phy: micrel: add generic clock-mode-select support

2014-11-21T19:08:56+00:00

Add generic RMII-Reference-Clock-Select support.

Several Micrel PHY have an RMII-Reference-Clock-Select bit to select
25 MHz or 50 MHz clock mode. Recently, support for configuring this
through device tree for KSZ8021 and KSZ8031 was added.

Generalise this support so that it can be configured for other PHY types
as well.

Note that some PHY revisions (of the same type) has this bit inverted.
This should be either configurable through a new device-tree property,
or preferably, determined based on PHY ID if possible.

Also note that this removes support for setting 25 MHz mode from board
files which was also added by the above mentioned commit 45f56cb82e45
("net/phy: micrel: Add clock support for KSZ8021/KSZ8031").

net: phy: micrel: add has-broadcast-disable flag to type data

2014-11-21T19:08:56+00:00

Add has_broadcast_disable flag to type-data and generic config_init.

This allows us to remove the ksz8081 config_init callback.

Note that ksz8021_config_init is kept for now due to a95a18afe4c8
("phy/micrel: KSZ8031RNL RMII clock reconfiguration bug").

Parse the "micrel,led-mode" property at probe, rather than at config_init

net: phy: micrel: add device-type abstraction

2014-11-21T19:08:56+00:00

Add structured device-type information and support for generic led-mode
setup to the generic config_init callback.

This is a first step in ultimately getting rid of device-type specific
callbacks.
