Wan Ahmad Zainie e539f435cb spi: dw: Add support for DesignWare DWC_ssi ... This patch adds initial support for DesignWare DWC_ssi soft IP. DWC_ssi is the enhanced version of DW_apb_ssi, which is currently supported by this driver. Their registers are same, but the bit fields of register CTRLR0 are different. DWC_ssi has additional features compared to DW_apb_ssi. Major enhancements in DWC_ssi are hyper bus protocol, boot mode support and advanced XIP support. DWC_ssi is an AHB slave device, whilst DW_apb_ssi is an APB slave device.
