From 916354e7c7c08aedff37bdf322e049836aa8d2aa Mon Sep 17 00:00:00 2001 From: Antoniu Miclaus Date: Tue, 21 Oct 2025 10:53:46 +0000 Subject: [PATCH] iio: adc: ad4080: add support for AD4086 Add support for AD4086 14-bit SAR ADC. The AD4086 differs from AD4080 in resolution (14-bit vs 20-bit) and LVDS CNV clock count maximum (4 vs 7). Changes: - Add AD4086_CHIP_ID definition (0x0056) - Create ad4086_channel with 14-bit resolution and 16-bit storage - Add ad4086_chip_info with lvds_cnv_clk_cnt_max = 4 - Register AD4086 in device ID and OF match tables Signed-off-by: Antoniu Miclaus Signed-off-by: Jonathan Cameron --- drivers/iio/adc/ad4080.c | 15 +++++++++++++++ 1 file changed, 15 insertions(+) diff --git a/drivers/iio/adc/ad4080.c b/drivers/iio/adc/ad4080.c index e2cdca2e91749..d6d0688adc3db 100644 --- a/drivers/iio/adc/ad4080.c +++ b/drivers/iio/adc/ad4080.c @@ -129,6 +129,7 @@ #define AD4081_CHIP_ID 0x0051 #define AD4083_CHIP_ID 0x0053 #define AD4084_CHIP_ID 0x0054 +#define AD4086_CHIP_ID 0x0056 #define AD4080_LVDS_CNV_CLK_CNT_MAX 7 @@ -444,6 +445,8 @@ static const struct iio_chan_spec ad4083_channel = AD4080_CHANNEL_DEFINE(16, 16) static const struct iio_chan_spec ad4084_channel = AD4080_CHANNEL_DEFINE(16, 16); +static const struct iio_chan_spec ad4086_channel = AD4080_CHANNEL_DEFINE(14, 16); + static const struct ad4080_chip_info ad4080_chip_info = { .name = "ad4080", .product_id = AD4080_CHIP_ID, @@ -484,6 +487,16 @@ static const struct ad4080_chip_info ad4084_chip_info = { .lvds_cnv_clk_cnt_max = 2, }; +static const struct ad4080_chip_info ad4086_chip_info = { + .name = "ad4086", + .product_id = AD4086_CHIP_ID, + .scale_table = ad4080_scale_table, + .num_scales = ARRAY_SIZE(ad4080_scale_table), + .num_channels = 1, + .channels = &ad4086_channel, + .lvds_cnv_clk_cnt_max = 4, +}; + static int ad4080_setup(struct iio_dev *indio_dev) { struct ad4080_state *st = iio_priv(indio_dev); @@ -642,6 +655,7 @@ static const struct spi_device_id ad4080_id[] = { { "ad4081", (kernel_ulong_t)&ad4081_chip_info }, { "ad4083", (kernel_ulong_t)&ad4083_chip_info }, { "ad4084", (kernel_ulong_t)&ad4084_chip_info }, + { "ad4086", (kernel_ulong_t)&ad4086_chip_info }, { } }; MODULE_DEVICE_TABLE(spi, ad4080_id); @@ -651,6 +665,7 @@ static const struct of_device_id ad4080_of_match[] = { { .compatible = "adi,ad4081", &ad4081_chip_info }, { .compatible = "adi,ad4083", &ad4083_chip_info }, { .compatible = "adi,ad4084", &ad4084_chip_info }, + { .compatible = "adi,ad4086", &ad4086_chip_info }, { } }; MODULE_DEVICE_TABLE(of, ad4080_of_match); -- 2.47.3
