Hi:
I work on one board based on at9g25evk board now. I find one issue that phy
IC isn't reset, so network can't work. Only the different crystal with evk
board is connected to PHY IC. I copy the phy-reset part of at9260 to at9g25. It
can work now. Please the maintainer of at9gx5 check this. The modification I do
is as below:
+
+#ifdef CONFIG_MACB
+int at91sam9x5ek_macb_hw_init(void)
+{
+ struct at91_pmc *pmc = (struct at91_pmc *)ATMEL_BASE_PMC;
+ struct at91_port *pioa = (struct at91_port *)ATMEL_BASE_PIOA;
+ struct at91_rstc *rstc = (struct at91_rstc *)ATMEL_BASE_RSTC;
+ unsigned long erstl;
+
+ /* Enable EMAC clock */
+ writel(1 << ATMEL_ID_EMAC0, &pmc->pcer);
+
+ erstl = readl(&rstc->mr) & AT91_RSTC_MR_ERSTL_MASK;
+
+ /* Need to reset PHY -> 500ms reset */
+ writel(AT91_RSTC_KEY | AT91_RSTC_MR_ERSTL(13) |
+ AT91_RSTC_MR_URSTEN, &rstc->mr);
+
+ writel(AT91_RSTC_KEY | AT91_RSTC_CR_EXTRST, &rstc->cr);
+
+ /* Wait for end hardware reset */
+ while (!(readl(&rstc->sr) & AT91_RSTC_SR_NRSTL))
+ ;
+
+ /* Restore NRST value */
+ writel(AT91_RSTC_KEY | erstl | AT91_RSTC_MR_URSTEN,
+ &rstc->mr);
+
+ at91_macb_hw_init();
+}
+#endif
