For configuration items with a size of 16, scarlett2_usb_get_config() was filling *buf with little-endian data. Update it to convert to CPU endian. This function is not currently used so affects nothing yet; will be used by the upcoming talkback feature. Signed-off-by:

The 18i8 and 18i20 Gen 3 support "speaker switching". Add a Speaker Switch control which can be set to Off/Main/Alt. When speaker switching is enabled or disabled, the interface may change the state of the Analog Outputs 3 and 4 routing and the global mute button, so use a flag private->speaker_switching_switched to note that those should be checked when the next "monitor other" notification is received.

Enabling/disabling speaker switching will update the mux configuration. To prepare for this, add a private->mux_updated flag and update the scarlett2_mux_src_enum_ctl_get() callback to check it. Signed-off-by:

Save the struct snd_kcontrol pointers for the sw_hw and mux controls. This is in preparation for speaker switching support which needs to be able to update those controls. Signed-off-by:

Split part of scarlett2_sw_hw_enum_ctl_put() out into scarlett2_sw_hw_change() so that the code which actually makes the change is available in its own function. This will be used by the speaker switching support which needs to set the SW/HW switch to HW when speaker switching is enabled. Signed-off-by:

Some inputs on Gen 3 models support software-selectable phantom power. Add support for getting and setting the state of those switches and the "Phantom Power Persistence" switch. Co-developed-by:

Some inputs on Gen 3 models have an "air" feature which can be enabled from the driver or (model-dependent) from the front panel. Add support for getting and setting the state of those switches. Signed-off-by:

Add initial support for the Focusrite Scarlett Solo and 2i2 devices: - They have no mixer - They don't support reporting sync status or levels - The configuration space is laid out differently to the other models - There is no level (line/inst) switch on input 1 of the Solo Co-developed-by:

Move scarlett2_usb_get() and scarlett2_usb_get_config() above the functions relating to updating the configuration so that scarlett2_usb_set_config() can call scarlett2_usb_get() in a subsequent patch. Signed-off-by:

Some models allow the level and pad settings to be controlled from the front-panel of the device. For these, the device will send an "input-other" notification to prompt the driver to re-read the status of those settings. Signed-off-by:

The current way of the scarlett2 mixer code managing the usb_mixer_elem_info object is wrong in two ways: it passes its internal index to the head.id field, and the val_type field is uninitialized. This ended up with the wrong execution at the resume because a bogus unit id is passed wrongly. Also, in the later code extensions, we'll have more mixer elements, and passing the index will overflow the unit id size (of 256). This patch corrects those issues. It introduces a new value type, USB_MIXER_BESPOKEN, which indicates a non-standard mixer element, and use this type for all scarlett2 mixer elements, as well as initializing the fixed unit id 0 for avoiding the overflow.

The Level Meter control had a fixed number of channels and therefore only worked with the 18i20 Gen 2. Fix the control to contain the correct number of channels. Signed-off-by:

The scarlett2_ports struct contains both generic (hardware IDs and descriptions) and model-specific (port count) data. Remove the generic data from the scarlett2_device_info struct so it is not repeated for every model. Signed-off-by:

Some Gen 3 devices do not put all of the mux entries for the same port types together in order in the "set mux" message data. To prepare for this, replace the struct scarlett2_ports num[] array and the assignment_order[] array with mux_assignment[], a list of port types and ranges that is defined in the struct scarlett2_device_info.

For each analogue output, in addition to the output volume (gain) control, the hardware also has a mute control. Add ALSA mute controls for each analogue output. If the device has the line_out_hw_vol feature, then the mute control is disabled along with the output volume control when the switch is set to HW. Signed-off-by:

The info variable is not used by snd_scarlett_gen2_init() except to pass it to snd_scarlett_gen2_controls_create(), so move the lookup into that function. Signed-off-by:

Add the USB device ID to the scarlett2_device_info struct so that the switch statement which finds the appropriate struct can be replaced with a loop that looks through an array of pointers to those structs. Suggested-by:

The function hda_tegra_first_init() neglects to check the return value after executing platform_get_irq(). hda_tegra_first_init() should check the return value (if negative error number) for errors so as to not pass a negative value to the devm_request_irq(). Fix it by adding a check for the return value irq_id. Signed-off-by:

At extending the available mixer values for 32bit types, we forgot to add the corresponding entries for the format dump in the proc output. This may result in OOB access. Here adds the missing entries.

Fix mixer control callbacks to use the correct members of the struct snd_ctl_elem_value. The use of value.integer and value.enumerated were swapped in a few places. Update scarlett2_mux_src_enum_ctl_put() to use min() instead of clamp() as value.enumerated.item is unsigned. Signed-off-by:

The private->vol_updated flag was being checked outside of the mutex_lock/unlock() of private->data_mutex leading to the volume data being fetched twice from the device unnecessarily or old volume data being returned.
