PCM1753: Regarding Linux Driver Support for PCM1753

Murali Chikkanna

Part Number: PCM1753

Hi TI,

Our team is currently working on integrating the PCM1753 into a Linux environment for our project.
In our research, we came across some E2E forums indicating that there was no Linux driver support for the PCM1753 about five years ago.
we are reaching out to inquire about the current status of Linux driver support for the PCM1753.
We are particularly interested in knowing if Texas Instruments has since developed or released Linux drivers for this product.

If there have been any updates or changes to the support status of PCM1753 in a Linux environment, we would greatly appreciate any information or guidance
you can provide.

Thank & Regards,

Murali Chikkanna

Sorry, we have no pcm1753 driver code, you can use this code for reference, pcm1789-i2c.c « codecs « soc « sound - kernel/git/torvalds/linux.git - Linux kernel source tree

You will change following setting in your code
const struct regmap_config pcm1789_regmap_config = {
	.reg_bits		= 8,
	.val_bits		= 16, /*pcm1753 register value is 16bit*/
	.max_register		= PCM1789_DAC_VOL_RIGHT,
	.reg_defaults		= pcm1789_reg_defaults,
	.num_reg_defaults	= ARRAY_SIZE(pcm1789_reg_defaults),
	.writeable_reg		= pcm1789_writeable_reg,
	.readable_reg		= pcm1789_accessible_reg,
};
