20457828b7bbSWolfram Sang	  This option enables support for a sloppy logic analyzer using polled
20467828b7bbSWolfram Sang	  GPIOs. Use the 'tools/gpio/gpio-sloppy-logic-analyzer' script with
20477828b7bbSWolfram Sang	  this driver. The script will make it easier to use and will also
20487828b7bbSWolfram Sang	  isolate a CPU for the polling task. Note that this is a last resort
20497828b7bbSWolfram Sang	  analyzer which can be affected by latencies, non-deterministic code
20507828b7bbSWolfram Sang	  paths, or NMIs. However, for e.g. remote development, it may be useful
20517828b7bbSWolfram Sang	  to get a first view and aid further debugging.
20527828b7bbSWolfram Sang
20537828b7bbSWolfram Sang	  If this driver is built as a module it will be called
20547828b7bbSWolfram Sang	  'gpio-sloppy-logic-analyzer'.
