Subject: [PATCH AUTOSEL 4.9 1/3] pinctrl: rockchip: enable gpio pclk for rockchip_gpio_to_irq
Date: Tue, 17 Nov 2020 07:57:57 -0500 [thread overview]
Message-ID: <20201117125759.600148-1-sashal@kernel.org> (raw)
From: Jianqun Xu <jay.xu@rock-chips.com>
[ Upstream commit 63fbf8013b2f6430754526ef9594f229c7219b1f ]
There need to enable pclk_gpio when do irq_create_mapping, since it will
