ASoC: rt722-sdca: Add a control to support CAE firmware update
Realtek CAE requires specific tuning parameters based on the system vendor and SKU. This patch adds a kcontrol to trigger the firmware loading process. Signed-off-by: Jack Yu <jack.yu@realtek.com> Link: https://patch.msgid.link/20260520053243.3645180-1-jack.yu@realtek.com Signed-off-by: Mark Brown <broonie@kernel.org>
