You are breaking both forward and backwards compatibility changing both the dts and the driver. If that is fine to do, then explicitly say so. A secondary issue is the binding and dts go via differ trees and we end up with intermittent warnings. > > Signed-off-by: Guodong Xu > --- > v2: Remove providers from the dts example. > Pass the 'make dt_binding_check' test. > --- > .../devicetree/bindings/mfd/spacemit,p1.yaml | 49 +++++++++++++++++++++- > 1 file changed, 47 insertions(+), 2 deletions(-) _______________________________________________ linux-riscv mailing list linux-riscv@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-riscv
