The mtd binding is always $ref'ed by other bindings, default selector should be from other binding files which ref'ed it. Now, "$nodename" in mtd.yaml turns into a "select" automatically such that a few binding check issues reported because it conflicts with sram devices(eg, qcom,imem.yaml, rules in folder sram/*) To avoid the automatically created "select" in mtd.yaml, adding: select: false Suggested-by: Bjorn Andersson <quic_bjorande@xxxxxxxxxxx> Fixes: 7bdc671822e9 ("dt-bindings: mtd: physmap: Reuse the generic definitions") Signed-off-by: Zhenhua Huang <quic_zhenhuah@xxxxxxxxxxx> --- Hi Bjorn, As the idea is from your comment, I added "Suggested-by" you. Please tell me if that's not suitable. Thanks.
