From 737e05bf034e9ce4cba97bdc818ded181ef23e4b Mon Sep 17 00:00:00 2001 From: Yoshihiro Shimoda Date: Fri, 21 Sep 2018 16:54:17 +0900 Subject: arm64: dts: renesas: revise properties for R-Car Gen3 SoCs' usb 2.0 R-Car Gen3 SoCs need to enable/deassert clocks/resets of both usb 2.0 host (included phy) and peripheral. Otherwise, other side device cannot work correctly. So, this patch revises properties of clocks and resets. After that, each device driver can enable/deassert clocks/resets by its self. Notes: - To work the renesas_usbhs driver correctly when host side drivers are disabled and the renesas_usbhs driver doesn't have multiple clock management, this patch doesn't change the order of the clocks property in each hsusb node. - This patch doesn't have any side-effects even if the renesas_usbhs driver doesn't have reset_control and multiple clock management.
