Subject: [PATCH v8 05/12] phy: qcom: qmp-usbc: Move reset config into PHY cfg
Date: Mon, 15 Dec 2025 20:42:01 +0800	[thread overview]
Message-ID: <20251215-add-displayport-support-for-qcs615-platform-v8-5-cbc72c88a44e@oss.qualcomm.com> (raw)
In-Reply-To: <20251215-add-displayport-support-for-qcs615-platform-v8-0-cbc72c88a44e@oss.qualcomm.com>

From: Xiangxu Yin <xiangxu.yin@oss.qualcomm.com>

The original reset list only works for USB-only PHYs. USB3DP PHYs require
different reset names such as "dp_phy", so they need a separate list.

Moving reset configuration into qmp_phy_cfg allows per-PHY customization
without adding special-case logic in DT parsing. The legacy DT path keeps
using the old hardcoded list, while non-legacy paths use cfg->reset_list.
