Notable differences against SM8550 LPASS pin controller: 1. Additional address space for slew rate thus driver uses LPI_FLAG_SLEW_RATE_SAME_REG and sets slew rate via different register. 2. Two new pin mux functions: qca_swr_clk and qca_swr_data Signed-off-by: Krzysztof Kozlowski Reviewed-by: Konrad Dybcio --- drivers/pinctrl/qcom/Kconfig | 10 + drivers/pinctrl/qcom/Makefile | 1 + .../pinctrl/qcom/pinctrl-sm8650-lpass-lpi.c | 255 ++++++++++++++++++ 3 files changed, 266 insertions(+) create mode 100644 drivers/pinctrl/qcom/pinctrl-sm8650-lpass-lpi.c diff --git a/drivers/pinctrl/qcom/Kconfig b/drivers/pinctrl/qcom/Kconfig index f84c0d3b7951..e0f2829c15d6 100644 --- a/drivers/pinctrl/qcom/Kconfig +++ b/drivers/pinctrl/qcom/Kconfig @@ -124,4 +124,14 @@ config PINCTRL_SM8550_LPASS_LPI (Low Power Island) found on the Qualcomm Technologies Inc SM8550 platform. +config PINCTRL_SM8650_LPASS_LPI + tristate "Qualcomm Technologies Inc SM8550 LPASS LPI pin controller driver" + depends on ARM64 || COMPILE_TEST + depends on PINCTRL_LPASS_LPI + help + This is the pinctrl, pinmux, pinconf and gpiolib driver for the + Qualcomm Technologies Inc LPASS (Low Power Audio SubSystem) LPI + (Low Power Island) found on the Qualcomm Technologies Inc SM8650 + platform. + endif diff --git a/drivers/pinctrl/qcom/Makefile b/drivers/pinctrl/qcom/Makefile index 5910e08c84ce..f7b410e59bf1 100644 --- a/drivers/pinctrl/qcom/Makefile +++ b/drivers/pinctrl/qcom/Makefile @@ -58,5 +58,6 @@ obj-$(CONFIG_PINCTRL_SM8450) += pinctrl-sm8450.o obj-$(CONFIG_PINCTRL_SM8450_LPASS_LPI) += pinctrl-sm8450-lpass-lpi.o obj-$(CONFIG_PINCTRL_SM8550) += pinctrl-sm8550.o obj-$(CONFIG_PINCTRL_SM8550_LPASS_LPI) += pinctrl-sm8550-lpass-lpi.o +obj-$(CONFIG_PINCTRL_SM8650_LPASS_LPI) += pinctrl-sm8650-lpass-lpi.o obj-$(CONFIG_PINCTRL_SC8280XP_LPASS_LPI) += pinctrl-sc8280xp-lpass-lpi.o obj-$(CONFIG_PINCTRL_LPASS_LPI) += pinctrl-lpass-lpi.o diff --git a/drivers/pinctrl/qcom/pinctrl-sm8650-lpass-lpi.c b/drivers/pinctrl/qcom/pinctrl-sm8650-lpass-lpi.c new file mode 100644 index 000000000000..6e4be91ff085 --- /dev/null +++ b/drivers/pinctrl/qcom/pinctrl-sm8650-lpass-lpi.c @@ -0,0 +1,255 @@ +// SPDX-License-Identifier: GPL-2.0-only +/* + * Copyright (c) 2022-2023 Linaro Ltd. + */ + +#include +#include +#include + +#include "pinctrl-lpass-lpi.h" + +enum lpass_lpi_functions { + LPI_MUX_dmic1_clk, + LPI_MUX_dmic1_data, + LPI_MUX_dmic2_clk, + LPI_MUX_dmic2_data, + LPI_MUX_dmic3_clk, + LPI_MUX_dmic3_data, + LPI_MUX_dmic4_clk, + LPI_MUX_dmic4_data, + LPI_MUX_i2s0_clk, + LPI_MUX_i2s0_data, + LPI_MUX_i2s0_ws, + LPI_MUX_i2s1_clk, + LPI_MUX_i2s1_data, + LPI_MUX_i2s1_ws, + LPI_MUX_i2s2_clk, + LPI_MUX_i2s2_data, + LPI_MUX_i2s2_ws, + LPI_MUX_i2s3_clk, + LPI_MUX_i2s3_data, + LPI_MUX_i2s3_ws, + LPI_MUX_i2s4_clk, + LPI_MUX_i2s4_data, + LPI_MUX_i2s4_ws, + LPI_MUX_qca_swr_clk, + LPI_MUX_qca_swr_data, + LPI_MUX_slimbus_clk, + LPI_MUX_slimbus_data, + LPI_MUX_swr_rx_clk, + LPI_MUX_swr_rx_data, + LPI_MUX_swr_tx_clk, + LPI_MUX_swr_tx_data, + LPI_MUX_wsa_swr_clk, + LPI_MUX_wsa_swr_data, + LPI_MUX_wsa2_swr_clk, + LPI_MUX_wsa2_swr_data, + LPI_MUX_ext_mclk1_a, + LPI_MUX_ext_mclk1_b, + LPI_MUX_ext_mclk1_c, + LPI_MUX_ext_mclk1_d, + LPI_MUX_ext_mclk1_e, + LPI_MUX_gpio, + LPI_MUX__, +};
