This commit breaks my hardware configuration with ESP32-C3 + ST7789 based display. At least SPI2_HOST won't work at all.

Reverted. I'll double check next week. Sorry for the troubles :/

@arktrin did the initialization of the SPI master failed? I don't have any C3 module to test.

[arktrin]

I'm not sure what is happening, it compiles without any errors but SPI doesn't work at all.

[C47D]

It's been a while since I touch the SPI code, but maybe we should add some logging and use idf monitor to try found the issue.

Sorry for delay, I'm getting this error for my ESP32-C3:
spi: spi_bus_initialize(762): invalid dma channel, chip only support spi dma channel auto-alloc

[arktrin]

Just for testing I've replaced spi_bus_initialize(host, &buscfg, (spi_dma_chan_t)dma_channel); with spi_bus_initialize(host, &buscfg, 0); . Now spi configured and dma is not used at all but I'm getting another error:
E (1584) spi_master: check_trans_valid(689): txdata transfer > host maximum

[arktrin]

Not looking in the right place, spi_bus_initialize(host, &buscfg, 3); is the proper initialization for ESP32-C3 with auto-dma.

I've done PR #153 with a slight change to workaround the problem.
