They do what i want them to do. I've hot no idea, if they are acceptable in that form. diff -Napur a/drivers/tty/serial/meson_uart.c b/drivers/tty/serial/meson_uart.c --- a/drivers/tty/serial/meson_uart.c 2017-03-09 21:09:47.000000000 +0100 +++ b/drivers/tty/serial/meson_uart.c 2017-03-22 19:01:38.581613578 +0100 @@ -600,6 +600,7 @@ static int meson_uart_probe(struct platf struct resource *res_mem, *res_irq; struct uart_port *port; struct clk *clk; + struct clk *core_clk; int ret = 0; if (pdev->dev.of_node) @@ -625,6 +626,15 @@ static int meson_uart_probe(struct platf if (!port) return -ENOMEM; + core_clk = devm_clk_get(&pdev->dev, "core"); + if (!IS_ERR(core_clk)) { + ret = clk_prepare_enable(core_clk); + if(ret) { + dev_err(&pdev->dev, "couldn't enable clkc\n"); + return ret; + } + } + clk = clk_get(&pdev->dev, NULL); if (IS_ERR(clk)) return PTR_ERR(clk);
