Please also provide fix for other boards, I think you may not be able to test all boards, but make sure the patches are available, so people who interested can test, P.S I can help on milkv jupiter board > > Signed-off-by: Guodong Xu > --- > Guodong Xu (4): > regulator: spacemit-p1: Fix n_voltages for BUCK and LDO regulators > dt-bindings: mfd: spacemit,p1: Add individual regulator supply properties > regulator: spacemit-p1: Update supply names > riscv: dts: spacemit: k1-bananapi-f3: Update PMIC supply properties > > .../devicetree/bindings/mfd/spacemit,p1.yaml | 58 +++++++++++++++++++++- > arch/riscv/boot/dts/spacemit/k1-bananapi-f3.dts | 12 ++++- > drivers/regulator/spacemit-p1.c | 25 ++++++---- > 3 files changed, 80 insertions(+), 15 deletions(-) > --- > base-commit: c8a4a774a9b0d2c86593492625874e27e9cbc9a9 > change-id: 20260122-spacemit-p1-ae596efe885f > > Best regards, > -- > Guodong Xu > -- Yixun Lan (dlan) _______________________________________________ linux-riscv mailing list linux-riscv@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-riscv
