| 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 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. |
| |
| config AE3XX_TIMER |
| bool "AE3XX timer support" |
| depends on TIMER && NDS32 |
| help |
| Select this to enable a timer for AE3XX devices. |
