No. hisilicon,hi6421-pmic is used by this driver drivers/mfd/hi6421-pmic-core.c which provides support for the Hi6421 variants that don't use a MIPI SPMI bus. The "hisilicon,hi6421-spmi" compatible is for the new driver: drivers/mfd/hi6421-spmi-pmic.c And it is defined at: Documentation/devicetree/bindings/mfd/hisilicon,hi6421-spmi-pmic.yaml Both DT bindings and the driver were promoted from staging on this patch: https://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging.git/commit/?h=staging-next&id=9bd9e0de1cf5b89c4854be505ac0a418ddcc01bf Regards, Mauro _______________________________________________ linux-arm-kernel mailing list linux-arm-kernel@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-arm-kernel
