Traits with private bounds.

[strongwar]

pub struct Lcd<T,TX,RX>
where
    T: esp32_hal::prelude::_esp_hal_spi_InstanceDma<TX, RX>,
    TX:esp32_hal::dma::private::Tx, 
    RX:esp32_hal::dma::private::Rx,
{
    spi: T,
    fch: u8,
    fcl: u8,
}

I am trying to define a struct that holds a SpiDma struct, however, when I try to set its traits I can't since the TX and RX traits require private bounds. Is there a way to get around this?

Probably we were too strict here and the traits should be made public

Another user (on Matrix chat) also ran into this before

We are always happy to receive a PR - I can also look into this but currently I am a bit busy with something else so it might take some time
