[PATCH 2/5] mfd: intel_soc_pmic: Select designware i2c-bus driver

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



The Crystal Cove PMIC provides an ACPI OPRegion handler, which must be
available before other drivers using it are loaded, which is why
INTEL_SOC_PMIC is a bool.

Just having the driver is not enough, the driver for the i2c-bus must
also be built in, to ensure this, this patch adds a select for it.

While at it this patch also changes the human readable name of the Kconfig
option to make clear the INTEL_SOC_PMIC option selects support for the
Intel Crystal Cove PMIC and documents why this is a bool.
