Subject: [PATCH] phy-rockchip-pcie: remove deassert of phy_rst from exit callback
Date: Thu, 13 Oct 2016 12:42:13 +0800 [thread overview]
Message-ID: <1476333733-9696-1-git-send-email-shawn.lin@rock-chips.com> (raw)
The deassert of phy_rst from exit callback is incorrect as when
doing phy_exit, we expect the phy_rst is on asserted state which was
done by power_off callback, but not deasserted state. Meanwhile when
disabling clk_pciephy_ref, the assert/deassert signal can't actually
take effect on the phy. So let's fix it anyway.
