From 5206265f78e4e313bc982e289248a239cb3409e2 Mon Sep 17 00:00:00 2001 From: Marek Szyprowski Date: Wed, 11 Dec 2019 15:51:55 +0100 Subject: ARM: dts: exynos: Correct USB3503 GPIOs polarity Current USB3503 driver ignores GPIO polarity and always operates as if the GPIO lines were flagged as ACTIVE_HIGH. Fix the polarity for the existing USB3503 chip applications to match the chip specification and common convention for naming the pins. The only pin, which has to be ACTIVE_LOW is the reset pin. The remaining are ACTIVE_HIGH. This change allows later to fix the USB3503 driver to properly use generic GPIO bindings and read polarity from DT.
