The patch ASoC: Add MediaTek MT6660 Speaker Amp Driver has been applied to the asoc tree at https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git for-5.6 All being well this means that it will be integrated into the linux-next tree (usually sometime in the next 24 hours) and sent to Linus during the next merge window (or sooner if it is a bug fix), however if problems are discovered then the patch may be dropped or reverted. You may get further e-mails resulting from automated or manual testing and review of the tree, please engage with people reporting problems and send followup patches addressing any issues that are reported if needed. If any updates are required or you are submitting further changes they should be sent as incremental updates against current git, existing patches will not be replaced. Please add any relevant lists and maintainers to the CCs when replying to this mail. Thanks, Mark >From f289e55c6eeb4391101a42334e8c69bf8c9fe987 Mon Sep 17 00:00:00 2001 From: Jeff Chang <jeff_chang@xxxxxxxxxxx> Date: Thu, 16 Jan 2020 13:46:37 +0800 Subject: [PATCH] ASoC: Add MediaTek MT6660 Speaker Amp Driver The MT6660 is a boosted BTL class-D amplifier with V/I sensing. A built-in DC-DC step-up converter is used to provide efficient power for class-D amplifier with multi-level class-G operation. The digital audio interface supports I2S, left-justified, right-justified, TDM and DSP A/B format for audio in with a data out used for chip information like voltage sense and current sense, which are able to be monitored via DATAO through proper Signed-off-by: Jeff Chang <jeff_chang@xxxxxxxxxxx> Link: https://lore.kernel.org/r/1579153597-23286-1-git-send-email-richtek.jeff.chang@xxxxxxxxx Signed-off-by: Mark Brown <broonie@xxxxxxxxxx> --- sound/soc/codecs/Kconfig | 10 + sound/soc/codecs/Makefile | 2 + sound/soc/codecs/mt6660.c | 509 ++++++++++++++++++++++++++++++++++++++ sound/soc/codecs/mt6660.h | 77 ++++++ 4 files changed, 598 insertions(+) create mode 100644 sound/soc/codecs/mt6660.c create mode 100644 sound/soc/codecs/mt6660.h diff --git a/sound/soc/codecs/Kconfig b/sound/soc/codecs/Kconfig index de3f13dafc3c..52c51a9c5505 100644 --- a/sound/soc/codecs/Kconfig +++ b/sound/soc/codecs/Kconfig @@ -125,6 +125,7 @@ config SND_SOC_ALL_CODECS select SND_SOC_ML26124 if I2C select SND_SOC_MT6351 if MTK_PMIC_WRAP select SND_SOC_MT6358 if MTK_PMIC_WRAP + select SND_SOC_MT6660 if I2C select SND_SOC_NAU8540 if I2C select SND_SOC_NAU8810 if I2C select SND_SOC_NAU8822 if I2C @@ -1573,6 +1574,15 @@ config SND_SOC_MT6358 Enable support for the platform which uses MT6358 as external codec device. +config SND_SOC_MT6660 + tristate "Mediatek MT6660 Speaker Amplifier" + depends on I2C + help + MediaTek MT6660 is a smart power amplifier which contain + speaker protection, multi-band DRC, equalizer functions. + Select N if you don't have MT6660 on board. + Select M to build this as module. + config SND_SOC_NAU8540 tristate "Nuvoton Technology Corporation NAU85L40 CODEC" depends on I2C diff --git a/sound/soc/codecs/Makefile b/sound/soc/codecs/Makefile index 751f2b4d095b..7bd87a6371cf 100644 --- a/sound/soc/codecs/Makefile +++ b/sound/soc/codecs/Makefile @@ -123,6 +123,7 @@ snd-soc-msm8916-analog-objs := msm8916-wcd-analog.o snd-soc-msm8916-digital-objs := msm8916-wcd-digital.o snd-soc-mt6351-objs := mt6351.o snd-soc-mt6358-objs := mt6358.o +snd-soc-mt6660-objs := mt6660.o snd-soc-nau8540-objs := nau8540.o snd-soc-nau8810-objs := nau8810.o snd-soc-nau8822-objs := nau8822.o @@ -419,6 +420,7 @@ obj-$(CONFIG_SND_SOC_MSM8916_WCD_ANALOG) +=snd-soc-msm8916-analog.o obj-$(CONFIG_SND_SOC_MSM8916_WCD_DIGITAL) +=snd-soc-msm8916-digital.o obj-$(CONFIG_SND_SOC_MT6351) += snd-soc-mt6351.o obj-$(CONFIG_SND_SOC_MT6358) += snd-soc-mt6358.o +obj-$(CONFIG_SND_SOC_MT6660) += snd-soc-mt6660.o obj-$(CONFIG_SND_SOC_NAU8540) += snd-soc-nau8540.o obj-$(CONFIG_SND_SOC_NAU8810) += snd-soc-nau8810.o obj-$(CONFIG_SND_SOC_NAU8822) += snd-soc-nau8822.o diff --git a/sound/soc/codecs/mt6660.c b/sound/soc/codecs/mt6660.c new file mode 100644 index 000000000000..a36c416caad4 --- /dev/null +++ b/sound/soc/codecs/mt6660.c @@ -0,0 +1,509 @@ +// SPDX-License-Identifier: GPL-2.0 // + +// Copyright (c) 2019 MediaTek Inc. + +#include <linux/module.h> +#include <linux/kernel.h> +#include <linux/version.h> +#include <linux/err.h> +#include <linux/i2c.h> +#include <linux/pm_runtime.h> +#include <linux/delay.h> +#include <linux/debugfs.h> +#include <sound/soc.h> +#include <sound/tlv.h> +#include <sound/pcm_params.h> + +#include "mt6660.h" + +struct reg_size_table { + u32 addr;
