[PATCH 1/4] dt-bindings: mtd: qcom,nandc: Add MDM9607 QPIC NAND controller
From: Stephan Gerhold
Date: Mon Jun 08 2026 - 09:27:56 EST
Add the qcom,mdm9607-nand compatible for the QPIC NAND controller used
inside the MDM9607 SoC.
On MDM9607, there is only a single controllable clock for the NAND
controller (RPM_SMD_QPIC_CLK). The same situation also applies e.g. for
qcom,sdx55-nand, but the corresponding device tree (qcom-sdx55.dtsi) works
around that by assigning a dummy clock (&nand_clk_dummy) to the second
clock ("aon") that is required by the dt-bindings. This is not really
useful, so avoid doing that for new platforms by excluding the second "aon"
clock entry in the dt-bindings.
