Cover letter [PATCH v1 0/3] ASoC: cs42l42: Fix handling of hard reset
These patches fix 3 problems with hard reset:
1. Ensure a minimum reset pulse width
2. Deal with ACPI overriding the requested default GPIO state
3. Avoid a race condition when hard-resetting a SoundWire peripheral that is already enumerated
