davinci_spi_probe(9)

🌸 NAME 🌸

okay bestie, this is davinci_spi_probe(9) from the Kernel API Manual, and it's literally the probe function for the SPI Master Controller. That's the whole name. Iconic. 💅

✨ SYNOPSIS ✨

int davinci_spi_probe (struct platform_device *pdev );

🎀 ARGUMENTS 🎀

• pdev — the platform_device structure that contains the plateform specific data. (Yes, plateform — that's the spelling in the source, bestie 😭🙈)

💅 DESCRIPTION 💅

According to Linux Device Model, this function will be invoked by Linux with a platform_device struct that contains the device specific info. So like, Linux hands it the device tea. 🫖

Then it gets to work: this function will map the SPI controller's memory, register IRQ, reset the SPI controller, and set its registers to default value. All the setup vibes. ✨

It will also invoke spi_bitbang_start to create work queue so that client driver can register transfer method to work queue. That's the whole flow, no cap. 🔥
