I got it compiled against my kernel, but not sure how to add it in my board file (My platform has no DT support). Should it be registered as spi slave device , I tried adding the following, { .modalias = "fb_ssd1306", .irq = -1, .max_speed_hz = 16000000, .bus_num = 2, .chip_select = 0, .mode = SPI_MODE_0, }, But nothing came up how do I register ? any quick pointer would be helpful.
