From 6d3d156eddbd89ce8b62eb54240a7f8c1edab531 Mon Sep 17 00:00:00 2001 From: Andre Przywara Date: Mon, 10 May 2021 11:01:31 +0100 Subject: [PATCH 012/158] drv:phy: sun4i-usb: Allow reset line to be shared The USB HCIs (and PHYs?) in Allwinner's newer generation SoCs (H616) rely on the reset line of USB PHY 2 to be de-asserted, even when only one of the other PHYs is actually in use. To make those ports work, we include this reset line in the HCIs' resets property, which requires this line to be shareable. Change the call to allocate the reset line to mark it as shared, to enable the other ports on those SoCs.
