+# %n the "kernel number" of the device.
+#    For example, 'sda3' has a "kernel number" of '3'
+# %e the smallest number for that name which does not matches an existing node
+# %k the kernel name for the device
+# %M the kernel major number for the device
+# %m the kernel minor number for the device
+# %b the bus id for the device

+# %s{filename} the content of a sysfs attribute
+# %% the '%' char itself

+# Backward compatibility with old OMAP UART-style ttyO0 naming
