STRUCT DAVINCI_SPI_PLATFORM_DATA(9)

📦 version 7.3.1, in nixpkgs unstable

💖 NAME 💖

okay bestie, welcome to struct davinci_spi_platform_data from the Kernel API Manual — yep, the title near the top is struct davin...latform_data(9) because truncation is doing its main character thing 😭. This page is literally Platform data for SPI master device on DaVinci ✨. That's the whole NAME vibe.

🌸 SYNOPSIS 🌸

Here's the struct, copied exactly, no edits, no cap:

       struct davinci_spi_platform_data {
           u8 version;
           u8 num_chipselect;
           u8 intr_line;
           u8 prescaler_limit;
           bool cshold_bug;
           enum dma_event_q        dma_event_q;
        };

🎀 Members 🎀

  • version — version of the SPI IP, bestie. Different DaVinci devices have slightly varying versions of the same IP. It's giving "same IP, different eras" 💅.
  • num_chipselect — number of chipselects supported by this SPI master. That's the count, periodt.
  • intr_line — interrupt line used to connect the SPI IP to the ARM interrupt controller withn the SoC. Possible values are 0 and 1. Yes, "withn" is right there in the original — don't come for me 😭.
  • prescaler_limit — max clock prescaler value. Big "respect the limit" energy.
  • cshold_bug — set this to true if the SPI controller on your chip requires a write to CSHOLD bit in between transfers (like in DM355). So if your chip is giving DM355, flip it to true 💅.
  • dma_event_q — DMA event queue to use if SPI_IO_TYPE_DMA is used for any device on the bus. Okay so this is the queue vibe for DMA situations.
