+Subject: [PATCH 178/203] BCM270X_DT: Use fixed-factor-clock for uart1
+
+The BCM2835 mini-UART is almost 8250-compatible, but there is
+a factor-of-two difference in the clock divider for the baud rate.
+The standard 8250 driver can be used unmodified provided we lie to it
+about the clock frequency, pretending it is double the actual value.
+The mini-UART block shares the core clock, and the current firmware
+uses a DT-parameter to update the clock-frequency property. Although it
+works, this isn't ideal because it exposes the firmware to a driver
+problem.
+
+This patch uses the fixed-factor-clock module to create a clock that is
+always twice the frequency of the core clock. (N.B. These "fixed" clocks
+just describe an existing clock, rather than changing any hardware
+settings.)
