* tegra: i2c: Drop LOG_DEBUGSimon Glass2021-03-271-1/+0
| | | | | | We should not enable debugging by default. Drop this. Signed-off-by: Simon Glass <sjg@chromium.org>
* common: Drop asm/global_data.h from common headerSimon Glass2021-02-021-0/+1
| | | | | | | | | | | | 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 <asm/global_data.h> at all, so remove that include.

* dm: treewide: Rename ..._platdata variables to just ..._platSimon Glass2020-12-131-1/+1
| | | | | | | Try to maintain some consistency between these variables by using _plat as a suffix for them. Signed-off-by: Simon Glass <sjg@chromium.org>
* dm: treewide: Rename ofdata_to_platdata() to of_to_plat()Simon Glass2020-12-132-4/+4
| | | | | | | This name is far too long. Rename it to remove the 'data' bits. This makes it consistent with the platdata->plat rename. Signed-off-by: Simon Glass <sjg@chromium.org>
* dm: treewide: Rename 'platdata' variables to just 'plat'Simon Glass2020-12-131-1/+1
| | | | | | | | | | We use 'priv' for private data but often use 'platdata' for platform data. We can't really use 'pdata' since that is ambiguous (it could mean private or platform data). Rename some of the latter variables to end with 'plat' for consistency. Signed-off-by: Simon Glass <sjg@chromium.org>
* dm: treewide: Rename auto_alloc_size members to be shorterSimon Glass2020-12-1312-14/+14
| | | | | | | | | | | | This construct is quite long-winded. In earlier days it made some sense since auto-allocation was a strange concept. But with driver model now used pretty universally, we can shorten this to 'auto'. This reduces verbosity and makes it easier to read. Coincidentally it also ensures that every declaration is on one line, thus making dtoc's job easier. Signed-off-by: Simon Glass <sjg@chromium.org>
* x86: sound: Correct error handlingSimon Glass2020-11-062-3/+3
| | | | | | | | A few functions have changed to return pin numbers or I2C addresses. The error checking for some of the callers is therefore wrong. Fix them. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Bin Meng <bmeng.cn@gmail.com>
* dm: acpi: Use correct GPIO polarity type in acpi_dp_add_gpio()Simon Glass2020-09-251-1/+1
| | | | | | | This function currently accepts the IRQ-polarity type. Fix it to use the GPIO type instead. Signed-off-by: Simon Glass <sjg@chromium.org>

| | | | | | | | | | This chip is used on coral and we need to generate ACPI tables for sound to make it work. Add a driver that does just this (i.e. at present does not actually support playing sound).

* dm: core: Create a new header file for 'compat' featuresSimon Glass2020-02-051-0/+1
| | | | | | | | | | | | At present dm/device.h includes the linux-compatible features. This requires including linux/compat.h which in turn includes a lot of headers. One of these is malloc.h which we thus end up including in every file in U-Boot. Apart from the inefficiency of this, it is problematic for sandbox which needs to use the system malloc() in some files. Move the compatibility features into a separate header file. Signed-off-by: Simon Glass <sjg@chromium.org>
* sandbox: sound: Handle errors better in sound_beep()Simon Glass2020-02-051-1/+4
| | | | | | | At present an error does not stop the sound-output loop. This is incorrect since nothing can be gained by trying to continue. Fix it. Signed-off-by: Simon Glass <sjg@chromium.org>
* sound: Add a new stop_play() methodSimon Glass2020-02-052-1/+31
| | | | | | | | | | | At present there is no positive indication that U-Boot has finished sending sound data. This means that it is not possible to power down an audio codec, for example. Add a new method that is called once all sound data has been sent. Add a new method for this, called when the sound_play() call is done. Signed-off-by: Simon Glass <sjg@chromium.org>

| | | | | | | | | When testing the sound system we don't need the hear the beeps. The testing works by checking the data that would be emitted.

| | | | | | | | | | | | The Intel High-definition Audio is a newer-generation audio system which provides for transfer of a large number of audio stream, each containing up to 16 channels. Add support for HDA as a library which can be used by other drivers. U-Boot currently uses only two channels (stereo).

| | | | | | | | | | Some audio codecs such as Intel HDA do not need to use digital data to play sounds, but instead have a way to emit beeps. Add this interface as an option. If the beep interface is not supported, then the sound uclass falls back to the I2S interface. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Bin Meng <bmeng.cn@gmail.com>

| | | | | | | | | | | | At present the 'beep' sound generates a waveform for only one channel even if two are being used. This means that the beep is twice the frequency it should be. Correct this by making it a parameter. The fix in a previous commit was correct for sandbox but not for other boards.

| | | | | | | | | | | 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 <sjg@chromium.org>
