From: Fabian Vogt Date: Mon, 26 Sep 2016 12:26:45 +0000 (+0200) Subject: serial: pl01x: expose skip_init platdata option in DT X-Git-Tag: v2017.01-rc1~171 X-Git-Url: https://git.sur5r.net/?a=commitdiff_plain;h=165316e38f7391b9269d2539edc1cceac25c16cc;p=u-boot 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.
