嗨,WayneWWW,
另外再請教一個問題:
tegra的PCIE驅動在哪裏檢測到發現PCIE設備並控制拉高rst呢?相關位置能否指點一下,
我們想學習一下。
Hi,
If this is rel-32 branch, then the driver code is kernel/nvidia/drivers/pci/dwc/pcie-tegra.c.
→
/* de-assert RST */
val = readl(pcie->appl_base + APPL_PINMUX);
val |= APPL_PINMUX_PEX_RST;
writel(val, pcie->appl_base + APPL_PINMUX);
thank you!
