-/**
- * intel_update_watermarks - update FIFO watermark values based on current modes
- *
- * Calculate watermark values for the various WM regs based on current mode
- * and plane configuration.
- *
- * There are several cases to deal with here:
- * - normal (i.e. non-self-refresh)
- * - self-refresh (SR) mode
- * - lines are large relative to FIFO size (buffer can hold up to 2)
- * - lines are small relative to FIFO size (buffer can hold more than 2
- * lines), so need to account for TLB latency
- *
- * The normal calculation is:
- * watermark = dotclock * bytes per pixel * latency
- * where latency is platform & configuration dependent (we assume pessimal
- * values here).
- *
- * The SR calculation is:
- * watermark = (trunc(latency/line time)+1) * surface width *
- * bytes per pixel
- * where
- * line time = htotal / dotclock
- * surface width = hdisplay for normal plane and 64 for cursor
- * and latency is assumed to be high, as above.
- *
- * The final value programmed to the register should always be rounded up,
- * and include an extra 2 entries to account for clock crossings.
- *
- * We don't use the sprite, so we can ignore that. And on Crestline we have
- * to set the non-SR watermarks to 8.

+ * intel_update_watermarks - update FIFO watermark values based on current modes
+ *
+ * Calculate watermark values for the various WM regs based on current mode
+ * and plane configuration.
+ *
+ * There are several cases to deal with here:
+ * - normal (i.e. non-self-refresh)
+ * - self-refresh (SR) mode
+ * - lines are large relative to FIFO size (buffer can hold up to 2)
+ * - lines are small relative to FIFO size (buffer can hold more than 2
+ * lines), so need to account for TLB latency
+ *
+ * The normal calculation is:
+ * watermark = dotclock * bytes per pixel * latency
+ * where latency is platform & configuration dependent (we assume pessimal
+ * values here).
+ *
+ * The SR calculation is:
+ * watermark = (trunc(latency/line time)+1) * surface width *
+ * bytes per pixel
+ * where
+ * line time = htotal / dotclock
+ * surface width = hdisplay for normal plane and 64 for cursor
+ * and latency is assumed to be high, as above.
+ *
+ * The final value programmed to the register should always be rounded up,
+ * and include an extra 2 entries to account for clock crossings.
+ *
+ * We don't use the sprite, so we can ignore that. And on Crestline we have
+ * to set the non-SR watermarks to 8.
