Hello, thank you for the feedback.

According to the downstream kernel's log, it seems like the panel and
the touchscreen controller are considered to be embedded in the same unit
(for example in [1]), with the touch input being transmitted via HID-over-I2C,
and since I did not find any reset gpio handling in that driver I opted to
include this reset here, unless there is a better way of going about this.

Best regards,

Diogo
