2019-11-27net: dm: fec: Fix regulator enable when using DM_REGULATORAdam Ford
When DM_REGULATOR is enabled, the driver attempts to call regulator_autoset() which expects the regulators to be on at boot and/or always on and fails if they are not true. For a more generic approach, this patch just calls regulator_set_enable() which shouldn't have such restrictions.

2019-04-11net: dm: fec: Fix phy-reset-duration clamping and defaultsMartin Fuzzey
The DT binding says: - phy-reset-duration : Reset duration in milliseconds. Should present only if property "phy-reset-gpios" is available. Missing the property will have the duration be 1 millisecond. Numbers greater than 1000 are invalid and 1 millisecond will be used instead. However the current code: - clamps values greater than 1000ms to 1000ms rather than 1. - does not initialize the delay if the property does not exist (else clause mismatch) - returns an error if phy-reset-gpios is not defined Fix all this and simplify by using dev_read_u32_default() Signed-off-by: Martin Fuzzey <martin.fuzzey@flowbird.group> Acked-by: Joe Hershberger <joe.hershberger@ni.com> (cherry picked from commit 331fcabe4f9b4c7ec58d070da039f875673c9c9d) Signed-off-by: Max Krummenacher <max.krummenacher@toradex.com>
