[PATCH] SoC: rt5682s: Disable jack detection interrupt during suspend
by Matthias Kaehlcke 14 Feb '23

14 Feb '23

The rt5682s driver switches its regmap to cache-only when the device suspends and back to regular mode on resume. When the jack detect interrupt fires rt5682s_irq() schedules the jack detect work. This can result in invalid reads from the regmap in cache-only mode if the work runs before the device has resumed: [ 19.672162] rt5682s 2-001a: ASoC: error at soc_component_read_no_lock on rt5682s.2-001a for register: [0x000000f0] -16 Disable the jack detection interrupt during suspend and re-enable it on resume. The driver already schedules the jack detection work on resume, so any state change during suspend is still handled.

[PATCH] ASoC: tlv320adcx140: extend list of supported samplerates
by Alexandru Ardelean 14 Feb '23

14 Feb '23

From: Steffen Aschbacher <steffen.aschbacher(a)stihl.de> The 'tlv320adcx140' driver currently supports 3 devices: TLV320ADC3140, TLV320ADC5140 and TLV320ADC6140. All 3 devices, support higher samplerates, up to 768-kHz according to their datasheets. In our applications, we only tested (and worked) with 96 kHz and 192 kHz. This change extends the list of supported sample-rates for these devices with 96 & 192 kHz.
