SGMII configuration depends on proper GT setting that's why when node has phys property call PSGTR driver to configure it properly.
Signed-off-by: Michal Simek <[email protected]> --- Changes in v3: - Separate phy init from phy power on (IP reset has to be between) Changes in v2: - Handle also cases where phy reference doesn't exist which means that u-boot doesn't need to configure it (configured via psu_init for example) - Error out where reference exists but driver is not compiled in - reported by Sean drivers/net/zynq_gem.c | 20 ++++++++++++++++++++ 1 file changed, 20 insertions(+) diff --git a/drivers/net/zynq_gem.c b/drivers/net/zynq_gem.c index 5cbe8d28304b..b751d28e611f 100644 --- a/drivers/net/zynq_gem.c +++ b/drivers/net/zynq_gem.c @@ -12,6 +12,7 @@ #include <common.h> #include <cpu_func.h> #include <dm.h> +#include <generic-phy.h> #include <log.h> #include <net.h> #include <netdev.h> @@ -715,6 +716,19 @@ static int zynq_gem_probe(struct udevice *dev) void *bd_space; struct zynq_gem_priv *priv = dev_get_priv(dev); int ret; + struct phy phy; + + if (priv->interface == PHY_INTERFACE_MODE_SGMII) { + ret = generic_phy_get_by_index(dev, 0, &phy); + if (!ret) { + ret = generic_phy_init(&phy); + if (ret) + return ret; + } else if (ret != -ENOENT) { + debug("could not get phy (err %d)\n", ret); + return ret; + } + } ret = zynq_gem_reset_init(dev); if (ret) @@ -771,6 +785,12 @@ static int zynq_gem_probe(struct udevice *dev) if (ret) goto err3; + if (priv->interface == PHY_INTERFACE_MODE_SGMII && phy.dev) { + ret = generic_phy_power_on(&phy); + if (ret) + return ret; + } + return ret; err3: -- 2.34.1
