Subject: [PATCH v9 34/38] phy: rockchip: usbdp: Rename mode to hw_mode
Date: Thu, 02 Jul 2026 01:36:12 +0200	[thread overview]
Message-ID: <20260702-rockchip-usbdp-cleanup-v9-34-e31efbb62d2e@collabora.com> (raw)
In-Reply-To: <20260702-rockchip-usbdp-cleanup-v9-0-e31efbb62d2e@collabora.com>

Rename mode field to hw_mode to make clear that this is the modes
currently supported by the hardware, but not necessarily requested
by software. I.e. it is only set by either the USB-C state machine
or device-tree if the PHY is used in a fixed routing setup.
