Subject: [PATCH net-next 2/2] net: stmmac: select STMMAC_RELATIVE_FLEX_PPS for stm32 SoCs
Date: Thu, 24 Jul 2025 14:31:19 +0200 [thread overview]
Message-ID: <20250724-relative_flex_pps-v1-2-37ca65773369@foss.st.com> (raw)
In-Reply-To: <20250724-relative_flex_pps-v1-0-37ca65773369@foss.st.com>
In order to simplify the generation of flexible PPS signals by passing
an time offset relative to the MAC system time, select
STMMAC_RELATIVE_FLEX_PPS for DWMAC_STM32 config.
E.g: "echo "0 3 0 1 1" > /sys/class/ptp/ptp0/period" generates a PPS
that has a 1s period, 3 seconds after entering the command for ptp0 clock,
given that the MAC system time stays stable.
