Subject: [PATCH v7 4/4] clk: qcom: add clock controller driver for qca8386/qca8084
Date:   Thu, 14 Sep 2023 13:46:39 +0800
Message-ID: <20230914054639.13075-5-quic_luoj@quicinc.com>
In-Reply-To: <20230914054639.13075-1-quic_luoj@quicinc.com>

The clock controller driver of qca8386/qca8084 is registered
as the MDIO device, the hardware register is accessed by MDIO bus
that is normally used to access general PHY device, which is
different from the current existed qcom clock controller drivers
using ioremap to access hardware clock registers.

MDIO bus is common utilized by both qca8386/qca8084 and other
PHY devices, so the mutex lock mdio_bus->mdio_lock should be
used instead of using the mutex lock of remap.

To access the hardware clock registers of qca8386/qca8084, there
is special MDIO frame sequence(three MDIO read/write operations)
need to be sent to device.
