test: test sandbox sound driver more rigorously

2022-12-05T16:43:21Z

Consider unexpected values for frequency: * negative frequency * zero frequency * frequency exceeding sampling frequency As in these cases the sum of the samples is zero also check the count of the samples. Signed-off-by: Heinrich Schuchardt Reviewed-by: Simon Glass

sound: avoid endless loop

2022-12-05T16:43:21Z

'sound play 1 100000' results in an endless loop on the sandbox. If the frequency exceeds half the sampling rate, zero out the output buffer. Fixes: 511ed5fdd389 ("SOUND: SAMSUNG: Add I2S driver") Signed-off-by: Heinrich Schuchardt Reviewed-by: Simon Glass

sound: enable building DA7219 driver with ACPIGEN=n

2022-07-08T13:05:47Z

sandbox_defconfig builds the DA7219 driver. It should be possible to build the sandbox without ACPI support. ACPI support in the DA7219 driver is only needed when creating an ACPI table. Fix building with ACPIGEN=n. Fixes: 0324b7123e22 ("sound: Add an ACPI driver for Dialog Semicondutor da7219") Signed-off-by: Heinrich Schuchardt

snd: enable building max98357a driver with ACPIGEN=n

sound: Fix buffer overflow in square wave generation

2022-04-29T15:11:36Z

Data is written for each channel but is only tracked as having one channel written. This resulted in a buffer overflow and corruption of the allocator's metadata which caused further problems when the buffer was later freed. This could be observed with sandbox unit tests. Resolve the overflow by tracking the writes for each channel.

tegra: i2c: Drop LOG_DEBUG

We should not enable debugging by default. Drop this. Signed-off-by: Simon Glass

common: Drop asm/global_data.h from common header

2021-02-02T20:33:42Z

Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include at all, so remove that include. Signed-off-by: Simon Glass Signed-off-by: Tom Rini

dm: treewide: Rename ..._platdata variables to just ..._plat

Try to maintain some consistency between these variables by using _plat as a suffix for them. Signed-off-by: Simon Glass
