Subject: [PATCH v4 13/16] phy: rockchip: usbdp: Rename mode_change to phy_needs_reinit
Date: Tue, 28 Apr 2026 18:13:52 +0200	[thread overview]
Message-ID: <20260428-rockchip-usbdp-cleanup-v4-13-7775671ece22@collabora.com> (raw)
In-Reply-To: <20260428-rockchip-usbdp-cleanup-v4-0-7775671ece22@collabora.com>

Right now the mode_change property is set whenever the mode changes
between USB-only, DP-only and USB-DP. It is needed, because on any
mode change the PHY needs to be re-initialized. Apparently at least
DP also requires a re-init when the cable orientation is changed,
which is currently not being done (except when the orientation switch
also involves a mode change). Prepare for this by renaming mode_change
to phy_needs_reinit.
