This soft IP is an AMBA version 2.0-compliant AHB slave device. Existing driver already supports the older APB version. Intel Keem Bay SPI controller is using this IP. This patchset is tested on Keem Bay evaluation module board. Changes since v4: - Rebased to latest linux-next, since v4 does not apply cleanly. Changes since v3: - DT changes for feature addition is done on snps,dw-apb-ssi.txt. - And then convert the updated snps,dw-apb-ssi.txt to DT schema format. Changes since v2: - Rebased to v5.7-rc4. - Change the order of the patches i.e. dt-bindings patches go last. Changes since v1: - Rework the third patch based on Rob's feedback.
