Subject: [PATCH v1 1/2] phy: qcom-qmp-pcie: add x4 lane EP support for sa8775p
Date: Tue, 7 Nov 2023 18:34:52 +0530 [thread overview]
Message-ID: <1699362294-15558-2-git-send-email-quic_msarkar@quicinc.com> (raw)
In-Reply-To: <1699362294-15558-1-git-send-email-quic_msarkar@quicinc.com>
Add support for x4 lane end point mode PHY found on sa8755p platform.
Reusing existing serdes and pcs_misc table for EP and moved
BIAS_EN_CLKBUFLR_EN register from RC serdes table to common serdes
table as this register is part of both RC and EP.
