Subject: [PATCH v3 05/15] phy: renesas: rcar-gen3-usb2: Check dr_mode when not using OTG
Date: Tue, 14 May 2019 09:55:55 -0500 [thread overview]
Message-ID: <20190514145605.19112-6-chris.brandt@renesas.com> (raw)
In-Reply-To: <20190514145605.19112-1-chris.brandt@renesas.com>
When not using OTG, the PHY will need to know if it should function as
host or peripheral by checking dr_mode in the PHY node (not the parent
controller node).
Signed-off-by: Chris Brandt <chris.brandt@renesas.com>
---
v3:
* changed 'if' to 'switch'
* use rcar_gen3_set_host_mode() instead of writel()
v2:
* added braces to else statement
* check if dr_mode is "host"
