Subject: [PATCH AUTOSEL 5.4 008/107] ARM: dts: sun8i: a83t: Correct USB3503 GPIOs polarity
Date: Fri, 24 Jan 2020 09:16:38 -0500 [thread overview]
Message-ID: <20200124141817.28793-8-sashal@kernel.org> (raw)
In-Reply-To: <20200124141817.28793-1-sashal@kernel.org>
From: Marek Szyprowski <m.szyprowski@samsung•com>
[ Upstream commit 1c226017d3ec93547b58082bdf778d9db7401c95 ]
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.
