Add a control to retrieve the power status from the interface (bus-powered, external-powered, or insufficient power). Mark the new scarlett2_notify_power_status() function with __always_unused until it gets used when the Gen 4 notification callback function arrays are added. Signed-off-by:

When phantom power is enabled or disabled, the autogain control cannot be enabled until the interface has signalled that the change is complete and the input is unmuted. Update those controls to be read-only during this time. Signed-off-by:

While the autogain function is running, the other input controls (select, link, gain, safe, level, air, and phantom) can't be modified. Update those controls to be read-only during this time. Signed-off-by:

Some devices in the Scarlett Gen 4 series have support for software-controllable input gain. Along with this comes a channel select option, an auto-gain feature, "safe" mode, and linking two channels into a stereo pair. Mark the new scarlett2_notify_input_*() functions with __always_unused until they get used when the Gen 4 notification callback function arrays are added. Signed-off-by:

Extend the existing "air" option support from Scarlett Gen 3, which had two states (off/on), to accommodate Scarlett Gen 4's new state: Presence + Drive. Signed-off-by:

Gen 2/3 interfaces would only use 0/1 values for input level and phantom power switch controls. Gen 4 interfaces use the second bit to indicate that the state should be changed (or is changing), and the input is to be muted (or is muted) while that happens. Add a "mute" flag to config items to enable this behaviour for the level/phantom controls. Signed-off-by:

Writing Scarlett Gen 4 parameters differs from Gen 2 and Gen 3: - the values are written into a shared write location - the values are only byte-sized - the read locations now extend beyond 0xFF - a separate NVRAM save step is no longer required This patch implements that alternate write style, triggered by setting the config item size field to zero. The write address is specified through a new config set field gen4_write_addr. Signed-off-by:

The Focusrite Scarlett Gen 4 Solo has Air and Phantom Power controls on analogue input #2 (the Gen 3 Solo had these controls on analogue input #1). Add air_input_first and phantom_first device info options to cater for this. These options are similar to the level_input_first option that was added for the Gen 3 Solo, but these new options do not require adjusting the index of the control. Signed-off-by:

The notification value for monitor_other on the large interfaces is the same as the notification value for direct_monitor on the 3rd Gen small interfaces. Add a separate scarlett3a_notifications array and split out the direct_monitor handling. Signed-off-by:

Gen 2/3 devices have a single notification value for "input other" changes. Gen 4 has separate notification values for level, pad, air, and phantom power changes. Therefore, split the input_other_updated field and the scarlett2_update_input_other() function into the four components so that they can be handled separately later. Signed-off-by:

db_scale_scarlett2_gain is the TLV for the output volume controls. Gen 4 has software-controllable input gain controls, so rename this to db_scale_scarlett2_volume so we can use that name for the inputs. Signed-off-by:

Currently-supported interfaces with a mixer have per-channel volume controls, but this changes in Gen 4. Add a check so that the Playback Volume and associated controls don't get created unless the SCARLETT2_CONFIG_LINE_OUT_VOLUME config item is present. Signed-off-by:

By splitting config set gen2 into gen2a/b (for 6i6/18i8 vs 18i20), and gen3b into gen3b/c (for 4i4/8i6 vs 18i8/18i20), we can use scarlett2_has_config_item() instead of the per-device line_out_hw_vol. As Gen 4 has a master volume control but no SW/HW switches, check for both SCARLETT2_CONFIG_MASTER_VOLUME and SCARLETT2_CONFIG_SW_HW_SWITCH as needed, even though for Gen 2 and Gen 3 the former implies the latter.

Scarlett Gen 2 and Gen 3 devices combine volume and dim/mute notifications. The Scarlett 4i4 Gen 4 has volume change notification but no dim/mute control so split dim_mute_update out from vol_update. Signed-off-by:

The struct scarlett2_usb_volume_status matched the config space layout of a few volume controls that could be read together and were in fixed locations between Gen 2 and Gen 3 devices. Gen 4 devices have removed, moved, and new related controls, so this needs to be cleaned up. By adding SCARLETT2_CONFIG_MASTER_VOLUME (the only config item that didn't already have its own entry, because it is read-only), we can remove: - struct scarlett2_usb_volume_state, - #define SCARLETT2_USB_VOLUME_STATUS_OFFSET, and - scarlett2_usb_get_volume_status() and replace with calls to scarlett2_usb_get_config().

Add ioctls: - SCARLETT2_IOCTL_SELECT_FLASH_SEGMENT - SCARLETT2_IOCTL_ERASE_FLASH_SEGMENT - SCARLETT2_IOCTL_GET_ERASE_PROGRESS The settings or the firmware flash segment can be selected and then erased (asynchronous operation), and the erase progress can be monitored. If the erase progress is not monitored, then subsequent hwdep operations will block until the erase is complete. Once the erase is started, ALSA controls that communicate with the device will all return -EBUSY, and the device must be rebooted. Signed-off-by:
