Chen-Yu Tsai 3b13b5a4f2 ASoC: mediatek: use reserved memory or enable buffer pre-allocation ... [ Upstream commit ec4a10ca4a ] In commit 32c9c06adb ("ASoC: mediatek: disable buffer pre-allocation") buffer pre-allocation was disabled to accommodate newer platforms that have a limited reserved memory region for the audio frontend. Turns out disabling pre-allocation across the board impacts platforms that don't have this reserved memory region. Buffer allocation failures have been observed on MT8173 and MT8183 based Chromebooks under low memory conditions, which results in no audio playback for the user. Since some MediaTek platforms already have dedicated reserved memory pools for the audio frontend, the plan is to enable this for all of them. This requires device tree changes. As a fallback, reinstate the original policy of pre-allocating audio buffers at probe time of the reserved memory pool cannot be found or used. This patch covers the MT8173, MT8183, MT8186 and MT8192 platforms for now, the reason being that existing MediaTek platform drivers that supported reserved memory were all platforms that mainly supported ChromeOS, and is also the set of devices that I can verify.
