+ * ATI Mach64 CT clock synthesis description.
+ *
+ * All clocks on the Mach64 can be calculated using the same principle:
+ *
+ * XTALIN * x * FB_DIV
+ * CLK = ----------------------
+ * PLL_REF_DIV * POST_DIV
+ *
+ * XTALIN is a fixed speed clock. Common speeds are 14.31 MHz and 29.50 MHz.
+ * PLL_REF_DIV can be set by the user, but is the same for all clocks.
+ * FB_DIV can be set by the user for each clock individually, it should be set
+ * between 128 and 255, the chip will generate a bad clock signal for too low
+ * values.
+ * x depends on the type of clock; usually it is 2, but for the MCLK it can also
+ * be set to 4.
+ * POST_DIV can be set by the user for each clock individually, Possible values
+ * are 1,2,4,8 and for some clocks other values are available too.
+ * CLK is of course the clock speed that is generated.
+ *
+ * The Mach64 has these clocks:
+ *
+ * MCLK The clock rate of the chip
+ * XCLK The clock rate of the on-chip memory
+ * VCLK0 First pixel clock of first CRT controller
+ * VCLK1 Second pixel clock of first CRT controller
+ * VCLK2 Third pixel clock of first CRT controller
+ * VCLK3 Fourth pixel clock of first CRT controller
+ * VCLK Selected pixel clock, one of VCLK0, VCLK1, VCLK2, VCLK3
+ * V2CLK Pixel clock of the second CRT controller.
+ * SCLK Multi-purpose clock
+ *
+ * - MCLK and XCLK use the same FB_DIV
+ * - VCLK0 .. VCLK3 use the same FB_DIV
+ * - V2CLK is needed when the second CRTC is used (can be used for dualhead);
+ * i.e. CRT monitor connected to laptop has different resolution than built
+ * in LCD monitor.
+ * - SCLK is not available on all cards; it is know to exist on the Rage LT-PRO,
+ * Rage XL and Rage Mobility. It is know not to exist on the Mach64 VT.
+ * - V2CLK is not available on all cards, most likely only the Rage LT-PRO,
+ * the Rage XL and the Rage Mobility
+ *
+ * SCLK can be used to:
+ * - Clock the chip instead of MCLK
+ * - Replace XTALIN with a user defined frequency
+ * - Generate the pixel clock for the LCD monitor (instead of VCLK)
+ */
+
+ /*
+ * It can be quite hard to calculate XCLK and MCLK if they don't run at the
+ * same frequency. Luckily, until now all cards that need asynchrone clock
+ * speeds seem to have SCLK.
+ * So this driver uses SCLK to clock the chip and XCLK to clock the memory.
+ */
+
+/* ------------------------------------------------------------------------- */
+
+/*
+ * PLL programming (Mach64 CT family)
+ *
+ *
+ * This procedure sets the display fifo. The display fifo is a buffer that
+ * contains data read from the video memory that waits to be processed by
+ * the CRT controller.
+ *
+ * On the more modern Mach64 variants, the chip doesn't calculate the
+ * interval after which the display fifo has to be reloaded from memory
+ * automatically, the driver has to do it instead.

+ * must be in a contigiuos format. The 2 bit cursor code values are
+ * as follows:
+ *
+ * 00 - pixel colour = CURSOR_CLR_0
+ * 01 - pixel colour = CURSOR_CLR_1
+ * 10 - pixel colour = transparent (current display pixel)

+ *
