From 6be109b31ccdb9c98e7be12687171f6602527a5d Mon Sep 17 00:00:00 2001 From: Arun Ramamurthy Date: Wed, 22 Apr 2015 16:04:11 -0700 Subject: phy: core: Add devm_of_phy_get_by_index to phy-core Some generic drivers, such as ehci, may use multiple phys and for such drivers referencing phy(s) by name(s) does not make sense. Instead of inventing new naming schemes and using custom code to iterate through them, such drivers are better of using nameless phy bindings and using this newly introduced API to iterate through them.

The workaround for this is to disable squelch detect before de-asserting reset, and re-enabling it after the reset de-assert is done. Add a sunxi specific phy function to allow the sunxi-musb glue to do this.
