+Subject: [PATCH] spi/of: Use DT aliases for assigning bus number
+
+Linux assigns a number to each spi_master in the system, but when the
+platform used the device tree, the numbers are dynamically assigned and
+are not predictable. In general this shouldn't matter since the kernel
+doesn't use the bus number for anything other than matching a bus to
+spi_boardinfo (not used for DT). However, sometimes userspace needs to
+figure out which bus is which, so it makes sense to use the global
+/aliases namespace to choose a specific bus number.
+
+It is safe to derive the bus number from an alias because aliases will
+never cause two buses to try and use the same bus number. (At one time
+the cell-index property was used for this purpose, but cell-index has
+the risk of an id collision).
