/**
* 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
* 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.
