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"
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"
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"
33 # initr_bootstage() requires a timer and is called before initr_dm()
34 # so only the early timer is available
37 In some cases the timer must be accessible before driver model is
40 use an early timer. These functions must be supported by your timer
44 bool "AG101P timer support"
47 Select this to enable a timer for AG01P devices.
50 bool "Altera timer support"
53 Select this to enable a timer for Altera devices. Please find
61 associated with timer tick.
64 bool "ARC timer support"
73 bool "Aspeed ast2400/ast2500 timer support"
77 Select this to enable timer for Aspeed ast2400/ast2500 devices.
78 This is a simple sys timer driver, it is compatible with lib/time.c,
85 bool "ATCPIT100 timer support"
88 Select this to enable a ATCPIT100 timer which will be embedded
92 bool "Atmel periodic interval timer support"
95 Select this to enable a periodic interval timer for Atmel devices,
110 Enables support for the Designware APB Timer driver. This timer is
114 bool "MPC83xx timer support"
117 Select this to enable support for the timer found on
125 This timer is present on Renesas RZ/A1 R7S72100 SoCs.
128 int "x86 TSC timer frequency in MHz when used as the early timer"
133 early timer and the frequency can neither be calibrated via some
144 At the moment, only the first timer is used by the driver.
147 bool "Omap timer support"
150 Select this to enable an timer for Omap devices.
153 bool "RISC-V timer support"
156 Select this to enable support for a generic RISC-V S-Mode timer
160 bool "Rockchip timer support"
163 Select this to enable support for the timer found on
167 bool "Sandbox timer support"
170 Select this to enable an emulated timer for sandbox. It gets
174 bool "STi timer support"
178 Select this to enable a timer for STi devices.
181 bool "STM32 timer support"
184 Select this to enable support for the timer found on
188 bool "x86 Time-Stamp Counter (TSC) timer support"
191 Select this to enable Time-Stamp Counter (TSC) timer for x86.
194 bool "Read the TSC timer base on start-up"
197 On x86 platforms the TSC timer tick starts at the value 0 on reset.
198 This it makes no sense to read the timer on boot and use that as the
208 bool "x86 TSC timer uses native calibration"
211 Selects native timer calibration for TPL and don't include the other
217 bool "MediaTek timer support"
220 Select this to enable support for the timer found on
224 bool "Microchip 64-bit periodic interval timer support"
228 interval timer.
