// UNKNOWABLE CARGO-CULTED MYSTERY MEAT

// I copied this command sequence from the Linux MIPI driver for the ST7701,
// written in C. The author of that driver _also_ had no idea what this
// command sequence does or means, and claims to have himself copied it from
// a sample provided by a Sitronix engineer. Since this is a Linux SPI
// driver for the ST7701S written in Rust, there's ample opportunity for
// something to not line up.
//
// May whatever gods you pray to have mercy on our souls.
