## Summary It is now possible to configure SPI delays for st7789 controller if `CONFIG_SPI_DELAY_CONTROL` is set. Default values for SPI peripheral may be too long or too short, therefore the display controller set its own values as required. The default values in configuration are taken from the reference manual, but it is possible they may require tuning for different revisions or temperatures for example. ## Impact None unless `CONFIG_SPI_DELAY_CONTROL` is set, otherwise the delays are determined by ST7789 config options. This brings new configuration options for ST7789, but these have no effect on current config files. ## Testing Tested on 320 x 240 large display connected as 3 wire on SPI bus with DMA and 135 x 240 large display connected as 4 wire on SPI with DMA. -- This is an automated message from the Apache Git Service.
