ASoC: mediatek: use reserved memory or enable buffer pre-allocation [ Upstream commit ec4a10ca4a68ec97f12f4d17d7abb74db34987db ] In commit 32c9c06adb5b ("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.

Note that MT8186 was left out of this because it is registering some extra sinegen controls in the AFE-PCM probe callback and needs extra cleanups to be able to use the common bits.

ASoC: mediatek: mt8183: Check runtime resume during probe [ Upstream commit f0334fbfd107682d0c95f3f71e25f6127038e2b9 ] The MT8183 AFE probe uses pm_runtime_get_sync() before reading hardware defaults into the regmap cache, but does not check whether runtime resume failed. If regmap_reinit_cache() then fails, the temporary runtime PM usage count is also not released. Use pm_runtime_resume_and_get() so resume failures abort probe without leaking a usage count, and release the temporary reference before handling the regmap cache result.

ASoC: mediatek: mt8192: Check runtime resume during probe [ Upstream commit e24d5dde56a50946020b134fa8448869093db76a ] The MT8192 AFE probe enables runtime PM temporarily while reinitializing the regmap cache from hardware, but it uses pm_runtime_get_sync() without checking the return value. If runtime resume fails, probe keeps going without the device necessarily being accessible, and pm_runtime_get_sync() may leave the PM usage count incremented. The regmap_reinit_cache() failure path also returns before dropping the temporary PM reference and before clearing pm_runtime_bypass_reg_ctl. Use pm_runtime_resume_and_get() so resume failures do not leak a usage count, and clear the temporary bypass flag after dropping the probe PM reference on all regmap_reinit_cache() outcomes.
