4 bool "Enable driver model for timer drivers"
7 Enable driver model for timer access. It uses the same API as
8 lib/time.c, but now implemented by the uclass. The first timer
9 will be used. The timer is usually a 32 bits free-running up
10 counter. There may be no real tick, and no timer interrupt.
13 bool "Enable driver model for timer drivers in SPL"
14 depends on TIMER && SPL
16 Enable support for timer drivers in SPL. These can be used to get
17 a timer value when in SPL, or perhaps for implementing a delay
18 function. This enables the drivers in drivers/timer as part of an
22 bool "Enable driver model for timer drivers in TPL"
23 depends on TIMER && TPL
25 Enable support for timer drivers in TPL. These can be used to get
26 a timer value when in TPL, or perhaps for implementing a delay
27 function. This enables the drivers in drivers/timer as part of an
31 bool "Allow timer to be used early in U-Boot"
34 In some cases the timer must be accessible before driver model is
35 active. Examples include when using CONFIG_TRACE to trace U-Boot's
36 execution before driver model is set up. Enable this option to
37 use an early timer. These functions must be supported by your timer
38 driver: timer_early_get_count() and timer_early_get_rate().
41 bool "Altera timer support"
44 Select this to enable a timer for Altera devices. Please find
45 details on the "Embedded Peripherals IP User Guide" of Altera.
47 config ATMEL_PIT_TIMER
48 bool "Atmel periodic interval timer support"
51 Select this to enable a periodic interval timer for Atmel devices,
52 it is designed to offer maximum accuracy and efficient management,
53 even for systems with long response time.
55 config CADENCE_TTC_TIMER
56 bool "Cadence TTC (Triple Timer Counter)"
59 Enables support for the cadence ttc driver. This driver is present
60 on Xilinx Zynq and ZynqMP SoCs.
63 bool "Sandbox timer support"
64 depends on SANDBOX && TIMER
66 Select this to enable an emulated timer for sandbox. It gets
70 bool "x86 Time-Stamp Counter (TSC) timer support"
71 depends on TIMER && X86
73 Select this to enable Time-Stamp Counter (TSC) timer for x86.
76 bool "Omap timer support"
79 Select this to enable an timer for Omap devices.
82 bool "Aspeed ast2400/ast2500 timer support"
84 default y if ARCH_ASPEED
86 Select this to enable timer for Aspeed ast2400/ast2500 devices.
87 This is a simple sys timer driver, it is compatible with lib/time.c,
88 but does not support any interrupts. Even though SoC has 8 hardware
89 counters, they are all treated as a single device by this driver.
90 This is mostly because they all share several registers which
91 makes it difficult to completely separate them.
94 bool "STi timer support"
98 Select this to enable a timer for STi devices.
101 bool "ARC timer support"
102 depends on TIMER && ARC && CLK
104 Select this to enable built-in ARC timers.
105 ARC cores may have up to 2 built-in timers: timer0 and timer1,
106 usually at least one of them exists. Either of them is supported
110 bool "AG101P timer support"
111 depends on TIMER && NDS32
113 Select this to enable a timer for AG01P devices.
115 config ATCPIT100_TIMER
116 bool "ATCPIT100 timer support"
119 Select this to enable a ATCPIT100 timer which will be embeded
120 in AE3XX, AE250 boards.
122 config ROCKCHIP_TIMER
123 bool "Rockchip timer support"
126 Select this to enable support for the timer found on
130 bool "STM32 timer support"
133 Select this to enable support for the timer found on
