From 3f9f8a5b83f8aec40c9f4ee496046a695e333c45 Mon Sep 17 00:00:00 2001 From: Mateusz Kulikowski Date: Thu, 31 Mar 2016 23:12:17 +0200 Subject: [PATCH] ehci-hcd: Add init_after_reset Some host controllers need addidional initialization after ehci_reset() In non-dm implementation it is possible to use CONFIG_EHCI_HCD_INIT_AFTER_RESET. This patch adds similar option to ehci drivers using dm.
