Greetings,
This patch series addresses a missing hardware description issue for the
Qualcomm IPQ5018 Internal Ethernet PHY, where the data paths fail to
function correctly unless their dedicated RX and TX clocks are
explicitly enabled.
Further testing revealed that leaving these clocks unmanaged by the
kernel, they were inadvertently left enabled by the bootloader / QSDK
platform, which masked the issue. Testing a fresh network configuration
path exposed that the data link fails to work without explicit software
gating.
To correctly introduce the required multi-clock properties, the IPQ5018
binding definition must first be split away from the shared
qca,ar803x.yaml schema. This isolation is required because ar803x
references the generic ethernet-phy.yaml, which enforces a strict
single-clock limit constraint.
- Patch 1: Splits the IPQ5018 definitions to its own bindings schema
to accommodate the multi-clock requirement.
- Patch 2: Appends the missing RX/TX clock definitions into the IPQ5018
device tree before driver modification to avoid the driver
failing to probe.
- Patch 3: Updates the Qualcomm AT803x PHY driver framework to safely
acquire, enable, and gate these clocks upon link state
changes for runtime power optimization.
