Subject: [PATCH v2 2/2] spi: dw: Add support for snps,dwc-ssi-2.00a
Date: Fri, 19 Jun 2026 07:34:43 -0700	[thread overview]
Message-ID: <20260619143443.22267-3-changhuang.liang@starfivetech.com> (raw)
In-Reply-To: <20260619143443.22267-1-changhuang.liang@starfivetech.com>

Add a new compatible entry "snps,dwc-ssi-2.00a" for the Synopsys
DesignWare SSI controller version 2.00a. This variant uses the same
initialization routine as snps,dwc-ssi-1.01a (dw_spi_hssi_init).
