That means that when there are multiple capes ++being loaded in parallel the ones with the lowest priority number are loaded ++first. ++ ++Applying the device tree overlay makes the cape operational, as if it was part ++of the kernel's booting device tree. +diff --git a/Documentation/printk-formats.txt b/Documentation/printk-formats.txt +index 5962949..d1ba882 100644 +--- a/Documentation/printk-formats.txt ++++ b/Documentation/printk-formats.txt +@@ -324,10 +324,49 @@ Network device features: + + Passed by reference. + ++Command from struct task_struct ++ ++ %pT ls ++ ++ For printing executable name excluding path from struct ++ task_struct. ++ ++ Passed by reference. ++ ++Device tree nodes: ++ ++ %pO[fnpPcCFr] ++ ++ For printing device tree nodes.
