Subject: [RFC PATCH v2 3/3] ASoC: tegra: Enable flat_cache_default_is_zero for audio drivers
From: Sheetal <sheetal@...dia.com>
Set flat_cache_default_is_zero flag in Tegra audio driver regmap
configurations.
Tegra APE hardware has numerous registers with zero power-on-reset
values. Use flat_cache_default_is_zero to mark cache entries as valid
instead of adding all these registers to reg_defaults arrays.
This patch depends on:
