To allow this code to be used with driver model, change it to pass the data down to each function. Use the name 'priv' consistently throughout. Also rename max98095_update_bits() to max98095_bic_or() which is more descriptive and shorter, thus breaking fewer lines with the parameter addition.

This wouldn't matter except that a long sound (more than a second) has to be created as a single buffer, thus using a lot of memory. To better mimic what real sound drivers do, add support for double buffering in sandbox.

It supports setup() and play() methods. The sound_find_codec_i2s() function allows locating the linked codec and i2s devices. They can be referred to from uclass-private data. Add a uclass and a test for sound.

Simon Glass Date: Mon, 10 Dec 2018 10:37:44 -0700 Subject: [PATCH 33/40] dm: exynos: sound: Convert to use driver model Update snow's device tree and config to use driver model for sound. Also update the others as best we can. Spring does not appear to have audio support in the kernel. The smdk5250 and smdk5420 boards use a wolfson codec which I cannot test with. So the only boards that is tested and known to work are snow, pit and pi.
