From: Adam Ford Date: Tue, 2 Apr 2019 19:32:04 +0000 (-0500) Subject: ARM: dts: imx6q-logicpd: Reduce inrush current on USBH1 X-Git-Tag: v5.2-rc1~46^2^2~3^2 X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=7aedca875074b33795bc77066b325898b1eb8032;p=thirdparty%2Fkernel%2Flinux.git ARM: dts: imx6q-logicpd: Reduce inrush current on USBH1 Some USB peripherals draw more power, and the sourcing regulator take a little time to turn on. This patch fixes an issue where some devices occasionally do not get detected, because the power isn't quite ready when communication starts, so we add a bit of a delay.
