Firmware archive for the Realtek RTS5455 USB Type-C power delivery controller on Compal board LA-H151P, revision 1.0. The RTS5455 handles Type-C PD negotiation, so a corrupt image can cause charging or USB-C display problems even when the BIOS is fine. The firmware sits in a small dedicated flash next to the controller and is written with an SPI programmer. LA-xxxxP is Compal numbering. Confirm the board and revision match before flashing.
