Hi Konstantin
- ctx->gpios.updn = devm_gpiod_get(&dsi->dev, "updn", GPIOD_OUT_LOW);
- if (IS_ERR(ctx->gpios.updn)) {
- dev_err(&dsi->dev, "Couldn't get our updn GPIO\n");
- return PTR_ERR(ctx->gpios.updn);
- }
This gpio is never used, it is only read from DT
The gpio is initialized with low state. The state may be inverted by DT. The same for the "shlr". It is a vertical / horizontal inversion.
Ohh, then it makes sense again. Consider adding a comment so this becomes more obvious
