From: Jairaj Arava <jairaj.arava(a)intel.com> [ Upstream commit c1c1fc8103f794a10c5c15e3c17879caf4f42c8f ] In some Chrome platforms if OEM's use their own string as SYS_VENDOR than "Google", it leads to firmware load failure from intel/sof/community path. Hence, changing SYS_VENDOR to PRODUCT_FAMILY in which "Google" is used as common prefix and is supported in all Chrome platforms.

[Sound-open-firmware] [PATCH AUTOSEL 5.19 24/36] ASoC: SOF: add quirk to override topology mclk_id
by Sasha Levin 10 Oct '22

10 Oct '22

From: Pierre-Louis Bossart <pierre-louis.bossart(a)linux.intel.com> [ Upstream commit d136949dd8e2e309dc2f186507486b71cbe9acdb ] Some Intel-based platforms rely on a topology file that hard-codes the use of MCLK0. This is incorrect in 10% of the cases. Rather than generating yet another set of topology files, this patch adds a kernel module parameter to override the topology value. In hindsight, we should never have allowed mclks to be specified in topology, this is a hardware-level information that should not have been visible in the topology. Future patches will try to set this value automagically, e.g. by parsing the NHLT content.
