Subject: [PATCH 01/25] dt-bindings: net: dwmac: Validate PBL for all IP-cores
Date: Mon, 14 Dec 2020 12:15:51 +0300	[thread overview]
Message-ID: <20201214091616.13545-2-Sergey.Semin@baikalelectronics.ru> (raw)
In-Reply-To: <20201214091616.13545-1-Sergey.Semin@baikalelectronics.ru>

Indeed the maximum DMA burst length can be programmed not only for DW
xGMACs, Allwinner EMACs and Spear SoC GMAC, but in accordance with [1]
for Generic DW *MAC IP-cores. Moreover the STMMAC set of drivers parse
the property and then apply the configuration for all supported DW MAC
devices. All of that makes the property being available for all IP-cores
the bindings supports. Let's make sure the PBL-related properties are
validated for all of them by the common DW MAC DT schema.

[1] DesignWare Cores Ethernet MAC Universal Databook, Revision 3.73a,
    October 2013, p. 380.
