Subject: [PATCH 0/9] ASoC: ux500: Fix MSP lifecycle, clocking and resources
Date: Wed, 02 Sep 2026 00:43:43 +0200 [thread overview]
Message-ID: <20260902-ux500-msp-fixes-v1-0-da1447fd9f7b@kernel.org> (raw)
Repair independent correctness problems in the DB8500 multichannel
serial port driver. The series fixes duplex and repeated-prepare stream
ownership, error propagation, frame and divider programming, FIFO
watermarks, DAI validation, reset handling, and MMIO resource ownership.
It also removes obsolete PRCMU QoS calls which are unconditional stubs.
The register programming follows the DB8500 v2 reference manual. These
changes are independent of the later sound-card devicetree conversion.
