+Subject: tty: serial: drop ATH79 specific SoC symbols
+
+QCA MIPS support is being converted to pure OF. As part of this we are
+dropping the SOC_AR* symbols. Additionally the SERIAL_AR933X style tty
+is also found on a few SoCs newer that the AR933x.
+
+This patch changes the dependency to ATH79, thus fixing the 2 issues
+described above.
