From 165316e38f7391b9269d2539edc1cceac25c16cc Mon Sep 17 00:00:00 2001 From: Fabian Vogt Date: Mon, 26 Sep 2016 14:26:45 +0200 Subject: [PATCH] serial: pl01x: expose skip_init platdata option in DT To be able to represent the skip-init platdata element with OF_CONTROL, it needs to be read from the device tree as well and put into the platform data.
