+Subject: [PATCH 23/43] v4l: Group media bus pixel codes by types and sort them alphabetically
+
+Adding new pixel codes at the end of the enumeration will soon create a
+mess, so group the pixel codes by type and sort them by bus_width, bits
+per component, samples per pixel and order of subsamples.
+
+As the codes are part of the kernel ABI their value can't change when a
+new code is inserted in the enumeration, so they are given an explicit
+numerical value. When inserting a new pixel code developers must use and
+update the next free value.
+
