Subject: [PATCH 02/14] mfd: arizona: Add MODULE_SOFTDEP("pre: arizona_ldo1")
Date: Sun, 27 Dec 2020 22:12:20 +0100	[thread overview]
Message-ID: <20201227211232.117801-3-hdegoede@redhat.com> (raw)
In-Reply-To: <20201227211232.117801-1-hdegoede@redhat.com>

The (shared) probing code of the arizona-i2c and arizona-spi modules
takes the following steps during init:

1. Call mfd_add_devices() for a set of early child-devices, this
includes the arizona_ldo1 device which provides one of the
core-regulators.

2. Bulk enable the core-regulators.

3. Read the device id.

4. Call mfd_add_devices() for the other child-devices.

This sequence depends on 1. leading to not only the child-device
being created, but also the driver for the child-device binding
to it and registering its regulator.

This requires the arizona_ldo1 driver to be loaded before the
shared probing code runs. Add a doftdep for this to both modules to
ensure that this requirement is met.

Note this mirrors the existing MODULE_SOFTDEP("pre: wm8994_regulator")
in the wm8994 code, which has a similar init sequence.
