Subject: [U-Boot] [PATCH v1 0/2] sun8i_emac: set MDC divider for MDIO read/write
Date: Fri, 17 Feb 2017 18:46:51 +0100 [thread overview]
Message-ID: <cover.1487340707.git.philipp.tomsich@theobroma-systems.com> (raw)
To ensure compatibility with all PHYs, we need to keep the MDIO clock
(MDC) below 2.5MHz (the guaranteed operating limit from IEEE 802.3),
even if some PHYs will tolerate higher speeds.
This changeset also cleans up the MDIO read/write functions by
removing pointless bit-masking in a variable initialised to 0.
