20 * SiRFprimaII clock controller
21 * - 2 oscillators: osc-26MHz, rtc-32.768KHz
22 * - 3 standard configurable plls: pll1, pll2 & pll3
23 * - 2 exclusive plls: usb phy pll and sata phy pll
24 * - 8 clock domains: cpu/cpudiv, mem/memdiv, sys/io, dsp, graphic, multimedia,
25 * display and sdphy.
26 * Each clock domain can select its own clock source from five clock sources,
27 * X_XIN, X_XINW, PLL1, PLL2 and PLL3. The domain clock is used as the source
28 * clock of the group clock.
29 * - dsp domain: gps, mf
30 * - io domain: dmac, nand, audio, uart, i2c, spi, usp, pwm, pulse
31 * - sys domain: security
