Message-ID: <20230530095138.1302-2-pranavi.somisetty@amd.com> Date: Tue, 30 May 2023 03:51:37 -0600 From: Pranavi Somisetty <pranavi.somisetty@....com> To: <davem@...emloft.net>, <edumazet@...gle.com>, <kuba@...nel.org>, <pabeni@...hat.com>, <robh+dt@...nel.org>, <krzysztof.kozlowski+dt@...aro.org>, <nicolas.ferre@...rochip.com>, <claudiu.beznea@...rochip.com> CC: <git@....com>, <michal.simek@....com>, <harini.katakam@....com>, <radhey.shyam.pandey@....com>, <pranavi.somisetty@....com>, <netdev@...r.kernel.org>, <linux-kernel@...r.kernel.org>, <devicetree@...r.kernel.org> Subject: [PATCH net-next v3 1/2] dt-bindings: net: cdns,macb: Add rx-watermark property watermark value is the minimum amount of packet data required to activate the forwarding process. The watermark implementation and maximum size is dependent on the device where Cadence MACB/GEM is used. Signed-off-by: Pranavi Somisetty <pranavi.somisetty@....com> --- Changes v2: None (patch added in v2) Changes v3: 1. Fixed DT schema error: "scalar properties shouldn't have array keywords". 2. Modified description of rx-watermark to include units of the watermark value. 3. Modified the DT property name corresponding to rx_watermark in pbuf_rxcutthru to "cdns,rx-watermark". 4. Modified commit description to remove references to Xilinx platforms, since the changes aren't platform specific. --- Documentation/devicetree/bindings/net/cdns,macb.yaml | 9 +++++++++ 1 file changed, 9 insertions(+) diff --git a/Documentation/devicetree/bindings/net/cdns,macb.yaml b/Documentation/devicetree/bindings/net/cdns,macb.yaml index bef5e0f895be..2c733c061dce 100644 --- a/Documentation/devicetree/bindings/net/cdns,macb.yaml +++ b/Documentation/devicetree/bindings/net/cdns,macb.yaml @@ -109,6 +109,14 @@ properties: power-domains: maxItems: 1 + cdns,rx-watermark: + $ref: /schemas/types.yaml#/definitions/uint16 + description: + Set watermark value for pbuf_rxcutthru reg and enable + rx partial store and forward.
