These workarounds are implemented throughout + * this driver. This section documents the known issues and their corresponding + * mitigation strategies. + * + * 1. Unreliable Link Detection and Synchronized Reset Deadlock + * ------------------------------------------------------------ + * After a link loss or during link establishment, the DP83TG720 PHY may fail + * to detect or report link status correctly. As of June 2025, no public + * errata sheet for the DP83TG720 PHY documents this behavior. + * The "DP83TC81x, DP83TG72x Software Implementation Guide" application note + * (SNLA404, available at https://www.ti.com/lit/an/snla404/snla404.pdf) + * recommends performing a soft restart if polling for a link fails to establish + * a connection after 100ms. This procedure is adopted as the workaround for the + * observed link detection issue. + * + * However, in point-to-point setups where both link partners use the same + * driver (e.g. Linux on both sides), a synchronized reset pattern may emerge. + * This leads to a deadlock, where both PHYs reset at the same time and + * continuously miss each other during auto-negotiation. + * + * To address this, the reset procedure includes two components: + * + * - A **fixed minimum delay of 1ms** after a hardware reset. The datasheet + * "DP83TG720S-Q1 1000BASE-T1 Automotive Ethernet PHY with SGMII and RGMII" + * specifies this as the "Post reset stabilization-time prior to MDC preamble + * for register access" (T6.2), ensuring the PHY is ready for MDIO + * operations. + * + * - An **additional asymmetric delay**, empirically chosen based on + * master/slave role. This reduces the risk of synchronized resets on both + * link partners. Values are selected to avoid periodic overlap and ensure + * the link is re-established within a few cycles. + * + * The functions that implement this logic are: + * - dp83tg720_soft_reset() + * - dp83tg720_get_next_update_time() + * + * 2. Polling-Based Link Detection and IRQ Support + * ----------------------------------------------- + * Due to the PHY-specific limitation described in section 1, link-up events + * cannot be reliably detected via interrupts on the DP83TG720. Therefore, + * polling is required to detect transitions from link-down to link-up. + * + * While link-down events *can* be detected via IRQs on this PHY, this driver + * currently does **not** implement interrupt support. As a result, all link + * state changes must be detected using polling. + * + * Polling behavior: + * - When the link is up: slow polling (e.g. 1s). + * - When the link just went down: fast polling for a short time. + * - When the link stays down: fallback to slow polling. + * + * This design balances responsiveness and CPU usage.
