[PATCH v2 06/12] ASoC: qdsp6: q6afe: use of_platform_populate/depopulate()

From: Srinivas Kandagatla <hidden>
Date: 2018-06-26 09:22:40
Also in: alsa-devel, linux-arm-kernel, linux-arm-msm, lkml
Subsystem: qcom audio (asoc) drivers, sound, sound - soc layer / dynamic audio power management (asoc), the rest · Maintainers: Srinivas Kandagatla, Jaroslav Kysela, Takashi Iwai, Liam Girdwood, Mark Brown, Linus Torvalds

Now that the child nodes have there own compatible strings,
Use of_platform_populate/depopulate() instead of less common
of_platform_device_create()/destroy().
