Subject: [PATCH 0/2] ASoC: Add flag to ignore 0Hz sysclk requests
Date: Tue, 17 Mar 2026 09:49:08 +0000 [thread overview]
Message-ID: <20260317094910.1582011-1-sheetal@nvidia.com> (raw)
Commit 2458adb8f92a ("SoC: simple-card-utils: set 0Hz to sysclk
when shutdown") introduced 0Hz sysclk requests during stream
shutdown. On Tegra platforms, clocks such as AUD_MCLK have a
minimum allowed frequency, so passing 0Hz results in Boot and
Power Management Processor (BPMP) clock controller errors.
This series adds an ignore_zero_sysclk flag to simple-card-utils
so that platform drivers can opt out of these 0Hz requests, and
enables it for the Tegra audio graph card.
