2 	bool "AT91 clock drivers"
6 	  This option is used to enable the AT91 clock driver.
7 	  The driver supports the AT91 clock generator, including
8 	  the oscillators and PLLs, such as main clock, slow clock,
9 	  PLLA, UTMI PLL. Clocks can also be a source clock of other
10 	  clocks a tree structure, such as master clock, usb device
11 	  clock, matrix clock and generic clock.
12 	  Devices can use a common clock API to request a particular
13 	  clock, enable it and get its rate.
19 	  This option is used to enable the AT91 UTMI PLL clock
20 	  driver. It is the clock provider of USB, and UPLLCK is the
21 	  output of 480 MHz UTMI PLL, The souce clock of the UTMI
22 	  PLL is the main clock, so the main clock must select the
31 	  clock driver. There are H64MX and H32MX matrixes clocks,
33 	  matrix clock is to be configured as MCK if MCK does not
40 	  This option is used to enable the AT91 generic clock
41 	  driver. Some peripherals may need a second clock source
42 	  that may be different from the system clock. This second
43 	  clock is the generic clock (GCLK) and is managed by
