Subject: [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

Richard Fitzgerald (3):
  ASoC: cs42l42: Ensure a reset pulse meets minimum pulse width.
  ASoC: cs42l42: Don't rely on GPIOD_OUT_LOW to set RESET initially low
  ASoC: cs42l42: Avoid stale SoundWire ATTACH after hard reset
