We observed that the clk_pciephy_ref is still enabled when we fail to probe the driver. root@linaro-alip:~# grep pcie /sys/kernel/debug/clk/clk_summary clk_pciephy_ref 1 1 24000000 0 0 clk_pcie_pm 0 0 24000000 0 0 clk_pcie_core_cru 0 0 125000000 0 0 clk_pciephy_ref100m 0 0 100000000 0 0 aclk_pcie 0 0 148500000 0 0 aclk_perf_pcie 0 0 148500000 0 0 pclk_pcie 0 0 37125000 0 0 clk_pcie_core 0 0 0 0 0 clk_pciephy_ref is used by the PHY driver and we need to properly disable it for this case. Add error handling in rockchip_pcie_init_port() and rockchip_pcie_resume_noirq() to fix this issue.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
