[PATCH] phy: marvell: remove LED config override

From: Clemens Gruber
Date: Fri Jun 10 2016 - 13:44:00 EST


Configuring the PHY LED registers for the Marvell 88E1510 and others is
not possible, because regardless of the values in marvell,reg-init, it
is later overridden in m88e1121_config_aneg with a non-standard default.

This became visible after we moved the call of marvell_of_reg_init in
commit 79be1a1c9090 ("phy: marvell: Fix and unify reg-init behavior").
Moving it to _config_init was necessary due to the PHY state machine
getting stuck if the PHY interrupts were not enabled early on.
As that default LED configuration is set in _config_aneg, it overrides
the marvell,reg-init configuration from the device tree.

This patch removes this override and allows the user to again set the
PHY LED configuration through marvell,reg-init or if that does not
exist, keep the original defaults as documented in the datasheet.
