From: Roger Quadros Date: Thu, 13 Aug 2015 10:28:42 +0000 (+0300) Subject: usb: phy: phy-generic: Fix reset behaviour on legacy boot X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=762982db33b23029e98c844611e2e8beeb75bc0d;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git usb: phy: phy-generic: Fix reset behaviour on legacy boot The gpio-desc migration done in v4.0 caused a regression with legacy boots due to reversed reset logic. e.g. omap3-beagle USB host breaks on legacy boot. Request the reset GPIO with GPIOF_ACTIVE_LOW flag so that it matches the driver logic and pin behaviour.
