Could you use read_poll_timeout() for this ? read_poll_timeout() "op"
would be "xpcs_phy_read_pma" and "args" would be "dev,
PMA_MP_12G_16G_25G_SRAM)" , this:
"
ret = read_poll_timeout(xpcs_phy_read_pma, val, val & PMA_SRAM_INIT_DN,
10000, 500000, dev, PMA_MP_12G_16G_25G_SRAM);
if (ret)
... timeout ...
"
+ } while (!(val & PMA_SRAM_INIT_DN));
+
+ /* Assert SRAM external loading done */
+ xpcs_phy_write(dev, XPCS_PHY_GLOBAL, XPCS_PHY_REG(GLOBAL_CTRL_EX_0),
+ GLOBAL_CTRL_EX_0_PHY_SRAM_BYPASS);
+
+ /* 4.3 Poll for vendor-specific soft reset */
+ begin = get_timer(0);
+ do {
+ val = xpcs_read(dev, MDIO_MMD_PCS, XPCS_PHY_REG(PCS_DIG_CTRL1));
+ if (get_timer(begin) > 500) {
+ dev_err(dev, "Polling timeout, line: %d\n", __LINE__);
+ goto timeout;
