Before this can be applied: - Run "git log --oneline drivers/pci/controller/pcie-rockchip-host.c" and make your subject line match in structure and style. - Add a commit log. It should explain the problem this fixes. Since this changes a timeout, you should be able to cite something in the spec (either the PCIe spec or the Rockchip spec) that describes the time needed. - Add a signed-off-by: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/Documentation/process/submitting-patches.rst?id=v5.11#n361 - CC the relevant maintainers (use ./scripts/get_maintainer.pl) > --- > drivers/pci/controller/pcie-rockchip-host.c | 4 ++-- > 1 file changed, 2 insertions(+), 2 deletions(-) > > diff --git a/drivers/pci/controller/pcie-rockchip-host.c b/drivers/pci/controller/pcie-rockchip-host.c > index f1d08a1b1591..9da831b2b7c2 100644 > --- a/drivers/pci/controller/pcie-rockchip-host.c > +++ b/drivers/pci/controller/pcie-rockchip-host.c > @@ -332,7 +332,7 @@ static int rockchip_pcie_host_init_port(struct rockchip_pcie *rockchip) > /* 500ms timeout value should be enough for Gen1/2 training */ > err = readl_poll_timeout(rockchip->apb_base + PCIE_CLIENT_BASIC_STATUS1, > status, PCIE_LINK_UP(status), 20, > - 500 * USEC_PER_MSEC); > + 1000 * USEC_PER_MSEC); > if (err) { > dev_err(dev, "PCIe link training gen1 timeout!\n"); > goto err_power_off_phy; > @@ -349,7 +349,7 @@ static int rockchip_pcie_host_init_port(struct rockchip_pcie *rockchip) > > err = readl_poll_timeout(rockchip->apb_base + PCIE_CORE_CTRL, > status, PCIE_LINK_IS_GEN2(status), 20, > - 500 * USEC_PER_MSEC); > + 1000 * USEC_PER_MSEC); > if (err) > dev_dbg(dev, "PCIe link training gen2 timeout, fall back to gen1!\n"); > } > -- > 2.17.1 >
