dm: sandbox: Allow selection of sample rate and channels

2018-12-13T23:37:09Z

At present these parameters are hard-coded in the sdl interface code. Allow them to be specified by the driver instead. Signed-off-by: Simon Glass

dm: sound: Complete migration to driver model

2018-12-13T23:36:41Z

All users of sound are converted to use driver model. Drop the old code and the CONFIG_DM_SOUND option. Signed-off-by: Simon Glass

dm: sandbox: sound: Convert to use driver model

2018-12-13T23:36:30Z

Update sandbox's device tree and config to use driver model for sound. Use the double buffer for sound output so that we don't need to wait for the sound to complete before returning. Signed-off-by: Simon Glass

dm: core: Add a function to read into a unsigned int

2018-12-13T23:32:49Z

The current dev_read...() functions use s32 and u32 which are convenient for device tree but not so useful for normal code, which often wants to use normal integers for values. Add a helper which supports returning an unsigned int. Also add signed versions of the unsigned readers. Signed-off-by: Simon Glass

dm: sound: Create a uclass for sound

2018-12-13T23:32:49Z

The sound driver pulls together the audio codec and i2s drivers in order to actually make sounds. 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. Signed-off-by: Simon Glass

dm: sandbox: Update sound to use two buffers

2018-12-13T23:32:49Z

At present we use a single buffer for sound which means we cannot be playing one sound while queueing up the next. 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. Signed-off-by: Simon Glass

dm: sound: Create a uclass for i2s

2018-12-13T23:32:49Z

The i2s bus is commonly used with audio codecs. It provides a way to stream digital data sychronously in both directions. U-Boot only supports audio output, so this uclass is very simple, with a single tx_data() method. Add a uclass and a test for i2s. Signed-off-by: Simon Glass

dm: sound: Create a uclass for audio codecs

2018-12-13T23:32:49Z

An audio codec provides a way to convert digital data to sound and vice versa. Add a simple uclass which just supports setting the parameters for the codec. Signed-off-by: Simon Glass

- DWC3 and UDC cleanup

syscon: dm: Add a new method to get a regmap from DTS

2018-12-07T15:31:45Z

syscon_regmap_lookup_by_phandle() can be used to get the regmap of a syscon device from a reference in the DTS. It operates similarly to the linux version of the namesake function. Signed-off-by: Jean-Jacques Hiblot Reviewed-by: Simon Glass
