When a SPI instance offers I2S feature, two nodes are defined in SoC device tree to support both SPI and I2S. Merge SPI node and I2S nodes into a single node, to avoid hardware description duplication and compilation warnings. spi2sx label is used to identify the SPI instances which are supporting I2S feature. Rename nodes, to match new labels of SPI/I2S nodes in the SoC device tree on following boards: - STMP32MP15xx-DKx - STMP32MP157C-EV1 - STMP32MP15xx-dhcor-avenger96 - STMP32MP15xx-dhcom-drc02 In DT check utility, the spi2s2 node is identified as an spi node. The check_spi_bus_reg() function issues a warning "missing or empty reg property" if reg property is not defined in child nodes. Add reg property to STM32 I2S port node on STM32MP15XX-DK board to match this requirement and add related unit-address in node name.
