From: Trent Piepho Date: Fri, 10 May 2019 17:49:08 +0000 (+0000) Subject: net: phy: ti: Fix clock output DT property X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=2529dea8931849c2bf8ee32963ee846e8e06e390;p=u-boot.git net: phy: ti: Fix clock output DT property The code block reading the DT property for the clock output control was before the phy's DT node pointer was set, so it could never work. Move it after the node pointer is set. Also store the unsigned 32-bit property into an unsigned value, not a signed value, as the former will cause a problem if value overflows. For instance, if one were to add 0xffffffff as a code to mean the clock output should be turned off.
