config TIMER |
|
bool "Enable driver model for timer drivers" |
|
depends on DM |
|
help |
|
Enable driver model for timer access. It uses the same API as |
|
lib/time.c, but now implemented by the uclass. The first timer |
|
will be used. The timer is usually a 32 bits free-running up |
|
counter. There may be no real tick, and no timer interrupt. |
|
|
|
config SPL_TIMER |
|
bool "Enable driver model for timer drivers in SPL" |
|
depends on TIMER && SPL |
|
help |
|
Enable support for timer drivers in SPL. These can be used to get |
|
a timer value when in SPL, or perhaps for implementing a delay |
|
function. This enables the drivers in drivers/timer as part of an |
|
SPL build. |
|
|
|
config TPL_TIMER |
|
bool "Enable driver model for timer drivers in TPL" |
|
depends on TIMER && TPL |
|
help |
|
Enable support for timer drivers in TPL. These can be used to get |
|
a timer value when in TPL, or perhaps for implementing a delay |
|
function. This enables the drivers in drivers/timer as part of an |
|
TPL build. |
|
|
|
config TIMER_EARLY |
|
bool "Allow timer to be used early in U-Boot" |
|
depends on TIMER |
|
help |
|
In some cases the timer must be accessible before driver model is |
|
active. Examples include when using CONFIG_TRACE to trace U-Boot's |
|
execution before driver model is set up. Enable this option to |
|
use an early timer. These functions must be supported by your timer |
|
driver: timer_early_get_count() and timer_early_get_rate(). |
|
|
|
config ALTERA_TIMER |
|
bool "Altera timer support" |
|
depends on TIMER |
|
help |
|
Select this to enable a timer for Altera devices. Please find |
|
details on the "Embedded Peripherals IP User Guide" of Altera. |
|
|
|
config ATMEL_PIT_TIMER |
|
bool "Atmel periodic interval timer support" |
|
depends on TIMER |
|
help |
|
Select this to enable a periodic interval timer for Atmel devices, |
|
it is designed to offer maximum accuracy and efficient management, |
|
even for systems with long response time. |
|
|
|
config CADENCE_TTC_TIMER |
|
bool "Cadence TTC (Triple Timer Counter)" |
|
depends on TIMER |
|
help |
|
Enables support for the cadence ttc driver. This driver is present |
|
on Xilinx Zynq and ZynqMP SoCs. |
|
|
|
config DESIGNWARE_APB_TIMER |
|
bool "Designware APB Timer" |
|
depends on TIMER |
|
help |
|
Enables support for the Designware APB Timer driver. This timer is |
|
present on Altera SoCFPGA SoCs. |
|
|
|
config SANDBOX_TIMER |
|
bool "Sandbox timer support" |
|
depends on SANDBOX && TIMER |
|
help |
|
Select this to enable an emulated timer for sandbox. It gets |
|
time from host os. |
|
|
|
config X86_TSC_TIMER |
|
bool "x86 Time-Stamp Counter (TSC) timer support" |
|
depends on TIMER && X86 |
|
help |
|
Select this to enable Time-Stamp Counter (TSC) timer for x86. |
|
|
|
config OMAP_TIMER |
|
bool "Omap timer support" |
|
depends on TIMER |
|
help |
|
Select this to enable an timer for Omap devices. |
|
|
|
config AST_TIMER |
|
bool "Aspeed ast2400/ast2500 timer support" |
|
depends on TIMER |
|
default y if ARCH_ASPEED |
|
help |
|
Select this to enable timer for Aspeed ast2400/ast2500 devices. |
|
This is a simple sys timer driver, it is compatible with lib/time.c, |
|
but does not support any interrupts. Even though SoC has 8 hardware |
|
counters, they are all treated as a single device by this driver. |
|
This is mostly because they all share several registers which |
|
makes it difficult to completely separate them. |
|
|
|
config STI_TIMER |
|
bool "STi timer support" |
|
depends on TIMER |
|
default y if ARCH_STI |
|
help |
|
Select this to enable a timer for STi devices. |
|
|
|
config ARC_TIMER |
|
bool "ARC timer support" |
|
depends on TIMER && ARC && CLK |
|
help |
|
Select this to enable built-in ARC timers. |
|
ARC cores may have up to 2 built-in timers: timer0 and timer1, |
|
usually at least one of them exists. Either of them is supported |
|
in U-Boot. |
|

|
config AG101P_TIMER |
|
bool "AG101P timer support" |
|
depends on TIMER && NDS32 |
|
help |
|
Select this to enable a timer for AG01P devices. |
|

|
depends on TIMER |
|
help |
|
Select this to enable a ATCPIT100 timer which will be embeded |
|
in AE3XX, AE250 boards. |
