40config OMAP_MUX
41	bool "OMAP multiplexing support"
42	default y
43	help
44	  Pin multiplexing support for OMAP boards. If your bootloader
45	  sets the multiplexing correctly, say N. Otherwise, or if unsure,
46	  say Y.
47
48config OMAP_MUX_DEBUG
49	bool "Multiplexing debug output"
50	depends on OMAP_MUX
51	help
52	  Makes the multiplexing functions print out a lot of debug info.
53	  This is useful if you want to find out the correct values of the
54	  multiplexing registers.
55
56config OMAP_MUX_WARNINGS
57	bool "Warn about pins the bootloader didn't set up"
58	depends on OMAP_MUX
59	default y
60	help
61	  Choose Y here to warn whenever driver initialization logic needs
62	  to change the pin multiplexing setup.	 When there are no warnings
63	  printed, it's safe to deselect OMAP_MUX for your product.

65config OMAP_32K_TIMER
66	bool "Use 32KHz timer"
67	depends on ARCH_OMAP16XX
68	default ARCH_OMAP16XX
69	help
70	  Select this option if you want to enable the OMAP 32KHz timer.
71	  This timer saves power compared to the OMAP_MPU_TIMER, and has
72	  support for no tick during idle. The 32KHz timer provides less
73	  intra-tick resolution than OMAP_MPU_TIMER. The 32KHz timer is
74	  currently only available for OMAP16XX, 24XX, 34XX, OMAP4/5 and DRA7XX.
75
76	  On OMAP2PLUS this value is only used for CONFIG_HZ and
77	  CLOCK_TICK_RATE compile time calculation.
78	  The actual timer selection is done in the board file
79	  through the (DT_)MACHINE_START structure.
80
81config OMAP_MPU_TIMER
82	bool "Use mpu timer"
83	depends on ARCH_OMAP1
84	help
85	  Select this option if you want to use the OMAP mpu timer. This
86	  timer provides more intra-tick resolution than the 32KHz timer,
87	  but consumes more power.
88
89config OMAP_SERIAL_WAKE
90	bool "Enable wake-up events for serial ports"
91	depends on ARCH_OMAP1 && OMAP_MUX
92	default y
93	help
94	  Select this option if you want to have your system wake up
95	  to data on the serial RX line. This allows you to wake the
96	  system from serial console.
97
98config OMAP_RESET_CLOCKS
99	bool "Reset unused clocks during boot"
100	depends on ARCH_OMAP
101	help
102	  Say Y if you want to reset unused clocks during boot.
103	  This option saves power, but assumes all drivers are
104	  using the clock framework. Broken drivers that do not
105	  yet use clock framework may not work with this option.
106	  If you are booting from another operating system, you
107	  probably do not want this option enabled until your
108	  device drivers work properly.

124	depends on ARCH_OMAP15XX
125	help
126	  Support for the Palm Tungsten E PDA.  To boot the kernel, you'll
127	  need a PalmOS compatible bootloader; check out
128	  http://palmtelinux.sourceforge.net/ for more information.
129	  Say Y here if you have this PDA model, say N otherwise.

136	  Support for the Siemens SX1 phone. To boot the kernel,
137	  you'll need a SX1 compatible bootloader; check out
138	  http://forum.oslik.ru and
139	  https://www.handhelds.org/moin/moin.cgi/SiemensSX1
140	  for more information.
