STRUCT TI_ST_PLAT_DATA(9)

💅 NAME 💅

okay so struct ti_st_plat_data(9) is from the Kernel API Manual, and it's literally the platform data shared between the ST driver and the platform-specific board file which adds the ST device. main character struct energy, no cap 💖

✨ SYNOPSIS ✨

here's the struct exactly as it appears, bestie — do not come for the spacing:

       struct ti_st_plat_data {
           u32 nshutdown_gpio;
           unsigned char dev_name[UART_DEV_NAME_LEN];
           u32 flow_cntrl;
           u32 baud_rate;
           int (*suspend)(struct platform_device *, pm_message_t);
           int (*resume)(struct platform_device *);
           int (*chip_enable) (struct kim_data_s *);
           int (*chip_disable) (struct kim_data_s *);
           int (*chip_asleep) (struct kim_data_s *);
           int (*chip_awake) (struct kim_data_s *);
        };

• nshutdown_gpio — the Host's GPIO line to which the chip's BT_EN is connected. that's the pin's whole vibe check 🔌
• dev_name — the UART/TTY name to which the chip is interfaced, like /dev/ttyS1 ✨
• flow_cntrl — should always be 1, since UART's CTS/RTS is used for PM purposes. no cap, always 1, periodt 👑
• baud_rate — the baud rate supported by the Host UART controller; this will be shared across with the chip via a HCI VS command from the User-Space Init Mgr application. slay 🦋
• suspend — the OG page leaves this line with no separate blurb; its resume description is right below 👇
• resume — legacy PM routines hooked to platform specific board file, so as to take chip-host interface specific action. 😭
• chip_enable — no separate text on this line in the OG page; it sits with chip_disable below 🫶
• chip_disable — Platform/Interface specific mux mode setting, GPIO configuring, Host side PM disabling etc.. can be done here. 💅
• chip_asleep — no separate blurb on this line in the OG page; see chip_awake below 🌙
• chip_awake — Chip specific deep sleep states is communicated to Host specific board-xx.c to take actions such as cut UART clocks when chip asleep or run host faster when chip awake etc.. 🔥
