Subject: [PATCH v6 11/16] ALSA: hda: cs35l41: Remove cs35l41_hda_reg_sequence struct
Date: Sat, 9 Apr 2022 10:13:10 +0100 [thread overview]
Message-ID: <20220409091315.1663410-12-tanureal@opensource.cirrus.com> (raw)
In-Reply-To: <20220409091315.1663410-1-tanureal@opensource.cirrus.com>
Remove cs35l41_hd_reg_sequence as it adds a layer of flexibility not needed.
As cs35l41_hda_(start/stop)_bst is a single register, it can be replaced by
regmap_update_bits with usleep_range to wait for the same 3000us that
reg_sequence had.
