 42	bool "OMAP multiplexing support"
 43	default y
 44	help
 45	  Pin multiplexing support for OMAP boards. If your bootloader
 46	  sets the multiplexing correctly, say N. Otherwise, or if unsure,
 47	  say Y.
 48
 49config OMAP_MUX_DEBUG

 52	help
 53	  Makes the multiplexing functions print out a lot of debug info.
 54	  This is useful if you want to find out the correct values of the
 55	  multiplexing registers.

 60	default y
 61	help
 62	  Choose Y here to warn whenever driver initialization logic needs
 63	  to change the pin multiplexing setup.	 When there are no warnings
 64	  printed, it's safe to deselect OMAP_MUX for your product.

 66config OMAP_32K_TIMER
 67	bool "Use 32KHz timer"
 68	depends on ARCH_OMAP16XX
 69	default ARCH_OMAP16XX
 70	help
 71	  Select this option if you want to enable the OMAP 32KHz timer.
 72	  This timer saves power compared to the OMAP_MPU_TIMER, and has
 73	  support for no tick during idle. The 32KHz timer provides less
 74	  intra-tick resolution than OMAP_MPU_TIMER. The 32KHz timer is
 75	  currently only available for OMAP16XX, 24XX, 34XX, OMAP4/5 and DRA7XX.
 76
 77	  On OMAP2PLUS this value is only used for CONFIG_HZ and
 78	  CLOCK_TICK_RATE compile time calculation.
 79	  The actual timer selection is done in the board file
 80	  through the (DT_)MACHINE_START structure.
 81
 82config OMAP_MPU_TIMER
 83	bool "Use mpu timer"
 84	depends on ARCH_OMAP1
 85	help
 86	  Select this option if you want to use the OMAP mpu timer. This
 87	  timer provides more intra-tick resolution than the 32KHz timer,
 88	  but consumes more power.
 89
 90config OMAP_SERIAL_WAKE
 91	bool "Enable wake-up events for serial ports"
 92	depends on ARCH_OMAP1 && OMAP_MUX
 93	default y
 94	help
 95	  Select this option if you want to have your system wake up
 96	  to data on the serial RX line. This allows you to wake the
 97	  system from serial console.
 98
 99config OMAP_RESET_CLOCKS
100	bool "Reset unused clocks during boot"
101	depends on ARCH_OMAP
102	help
103	  Say Y if you want to reset unused clocks during boot.
104	  This option saves power, but assumes all drivers are
105	  using the clock framework. Broken drivers that do not
106	  yet use clock framework may not work with this option.
107	  If you are booting from another operating system, you
108	  probably do not want this option enabled until your
109	  device drivers work properly.
