CONFIG_PANEL_LCD_PROTO: LCD communication mode (0=parallel 8 bits, 1=serial)

General informations

The Linux kernel configuration item CONFIG_PANEL_LCD_PROTO has multiple definitions:

LCD communication mode (0=parallel 8 bits, 1=serial) found in drivers/auxdisplay/Kconfig

The configuration item CONFIG_PANEL_LCD_PROTO:

• prompt: LCD communication mode (0=parallel 8 bits, 1=serial)
• type: int
• depends on: CONFIG_PANEL_PROFILE ="0" && CONFIG_PANEL_LCD ="1"
• defined in drivers/auxdisplay/Kconfig
• found in Linux kernels: 4.12–4.20, 5.0–5.19, 6.0–6.12, 6.13-rc+HEAD

Help text

This driver now supports any serial or parallel LCD wired to a parallel port. But before assigning signals, the driver needs to know if it will be driving a serial LCD or a parallel one. Serial LCDs only use 2 wires (SDA/SCL), while parallel ones use 2 or 3 wires for the control signals (E, RS, sometimes RW), and 4 or 8 for the data. Use 0 here for a 8 bits parallel LCD, and 1 for a serial LCD.
