Subject: [PATCH] ASoC: codecs: aw88261: only check PLL and clock state at
power-up

The SYSST check performed during device start requires SWS (amplifier switching, bit 8) and BSTS (boost finished, bit 9) on top of PLL lock and clock stability. Those bits cannot be asserted at this point in the
sequence: the check runs after amppd release but before the hmute/ULS-hmute release, and the amplifier neither switches nor finishes ramping its boost converter while it is still muted. With the Fairphone (Gen. 6) firmware profile, aw88261_dev_start() therefore always fails with

check sysst fail, reg_val=0x0011, check:0x311

and playback aborts, even though the amplifier is fine and PLL lock and stable clocks are present.

Check only PLL lock and clock stability, for which a definition already exists; this still re-validates the clocks after amppd release (aw88261_dev_check_syspll() checked them before it). This matches the vendor aw882xx driver, which only validates PLL lock and clock stability at this stage, and the in-tree aw88399 driver, which skips the SWS check whenever the amplifier may legitimately not be switching (AW88399_BIT_SYSST_NOSWS_CHECK).

PATCH 1/2 ASoC: codecs: aw88261: reduce log spam

From: Val Packett <[email protected]>

[ Upstream commit d90c361af215a9fa2a986d9f47d554d0cf3401dd ]

This driver would create a wall of logspam during initialization due to e.g. the PLL not being ready while waiting for it to stabilize. Change intermediate dev_err() calls to dev_dbg() to reduce the noise.

While here, log the detected chip ID when that check fails.
