STRUCT MADERA_PDATA(9)

✨ NAME ✨

struct madera_pdata(9) — from the Kernel API Manual — is the Configuration data for Madera devices struct. bestie, it’s the bundle of settings for Madera devices, and we’re gonna go through every single member, no skipping 💖

🌸 SYNOPSIS 🌸

       struct madera_pdata {
           struct gpio_desc *reset;
           struct arizona_ldo1_pdata ldo1;
           struct arizona_micsupp_pdata micvdd;
           unsigned int irq_flags;
           int gpio_base;
           const struct pinctrl_map *gpio_configs;
           int n_gpio_configs;
           u32 gpsw[MADERA_MAX_GPSW];
           struct madera_codec_pdata codec;
        };

💅 Members 💅

okay so every field is doing its little main-character thing:

• reset — the GPIO controlling /RESET; NULL means none. 💀
• ldo1 — substruct of pdata for the LDO1 regulator. 🎀
• micvdd — substruct of pdata for the MICVDD regulator. 🧚
• irq_flags — mode for the primary IRQ; defaults to active low. ⭐
• gpio_base — base GPIO number. 🔢
• gpio_configs — array of GPIO configurations (see Documentation/driver-api/pin-control.rst). 🦋
• n_gpio_configs — number of entries in gpio_configs. 🍓
• gpsw — general purpose switch mode setting. It depends on the external hardware connected to the switch. (See the SW1_MODE field in the datasheet for the available values for your codec.) 🔥
• codec — substruct of pdata for the ASoC codec driver. 🌈
