Changes in V4: -Created new patch to simplify code with dev_err_probe(). -Updated minor review comments. -Created new patch to check gpio-width. Changes in V3: -Created separate patch to arrange headers in sorting order. -Updated dt-bindings. -Created separate patch for Clock changes and runtime resume. and suspend. -Created separate patch for spinlock changes. -Created separate patch for remove support. -Fixed coverity errors. -Updated minor review comments.
