22 config OMAP_RESET_CLOCKS
23 bool "Reset unused clocks during boot"
26 Say Y if you want to reset unused clocks during boot.
27 This option saves power, but assumes all drivers are
28 using the clock framework. Broken drivers that do not
29 yet use clock framework may not work with this option.
30 If you are booting from another operating system, you
31 probably do not want this option enabled until your
32 device drivers work properly.
35 bool "OMAP multiplexing support"
39 Pin multiplexing support for OMAP boards. If your bootloader
40 sets the multiplexing correctly, say N. Otherwise, or if unsure,
44 bool "Multiplexing debug output"
47 Makes the multiplexing functions print out a lot of debug info.
48 This is useful if you want to find out the correct values of the
49 multiplexing registers.
51 config OMAP_MUX_WARNINGS
52 bool "Warn about pins the bootloader didn't set up"
56 Choose Y here to warn whenever driver initialization logic needs
57 to change the pin multiplexing setup. When there are no warnings
58 printed, it's safe to deselect OMAP_MUX for your product.
62 default OMAP_MPU_TIMER
67 Select this option if you want to use the OMAP mpu timer. This
68 timer provides more intra-tick resolution than the 32KHz timer,
69 but consumes more power.
72 bool "Use 32KHz timer"
73 depends on ARCH_OMAP16XX
75 Select this option if you want to enable the OMAP 32KHz timer.
76 This timer saves power compared to the OMAP_MPU_TIMER, and has
77 support for no tick during idle. The 32KHz timer provides less
78 intra-tick resolution than OMAP_MPU_TIMER. The 32KHz timer is
79 currently only available for OMAP-16xx.
83 config OMAP_32K_TIMER_HZ
84 int "Kernel internal timer frequency for 32KHz timer"
86 depends on OMAP_32K_TIMER
89 Kernel internal timer frequency should be a divisor of 32768,
93 bool "Use dual-mode timer"
94 depends on ARCH_OMAP16XX
96 Select this option if you want to use OMAP Dual-Mode timers.
99 prompt "Low-level debug console UART"
101 default OMAP_LL_DEBUG_UART1
103 config OMAP_LL_DEBUG_UART1
106 config OMAP_LL_DEBUG_UART2
109 config OMAP_LL_DEBUG_UART3
114 config OMAP_SERIAL_WAKE
115 bool "Enable wake-up events for serial ports"
119 Select this option if you want to have your system wake up
120 to data on the serial RX line. This allows you to wake the
121 system from serial console.
