2023-03-13efi: Use a fixed value for the timer clockSimon Glass
It is not yet clear how to read the timer via EFI. The current value seems much too high on a Framework laptop I tried. Adjust it to a lower hard-coded value for now. Signed-off-by: Simon Glass <[email protected]>
2023-03-06timer: fttmr010: return a previously deleted driver now ported to DMSergei Antonov
The fttmr010 timer driver was deleted by commit 29fc6f24926e ("ARM: remove a320evb board support") The original source file was: arch/arm/cpu/arm920t/a320/timer.c Return the driver to the codebase in a DM compatible form. A platform using fttmr010 will be submitted later. This hardware is described in the datasheet [1], starting from page 348. According to the datasheet, there is a Revision Register at offset 0x3C, which is not present in 'struct fttmr010'. Add it and debug() print revision in probe function.

2023-02-11timer: Tidy up use of notraceSimon Glass
Tracing is typically enabled by the time driver model starts up, so there is no point in adding a 'notrace' to the timer-init function. However, once the driver model timer is enabled, we do need to be able to access the timer's private data when reading the timer, so add it to the core function needed for that. Update the function's documentation while we are here. Signed-off-by: Simon Glass <[email protected]>

2023-01-20global: Finish CONFIG -> CFG migrationTom Rini
At this point, the remaining places where we have a symbol that is defined as CONFIG_... are in fairly odd locations. While as much dead code has been removed as possible, some of these locations are simply less obvious at first. In other cases, this code is used, but was defined in such a way as to have been missed by earlier checks. Perform a rename of all such remaining symbols to be CFG_... rather than CONFIG_...

2023-01-17timer: orion-timer: Fix problem in early_init_done()Stefan Roese
It was noticed that Clearfog is currently broken with this newly introduced early_init_done() function. Apparently the timer is enabled here when U-Boot is run but not configured - at least not correctly. Resulting in a hangup in the timer reading functions. To fix this, also read the value of the reload register and check it's value with the one written to by U-Boot. Only if this matches, the init has already been done.

We've noticed that at least one Kirkwood board (Pogo v4) has problems with the new orion DM timer implementation. Debugging revealed that this issue is related with the static variable "early_init_done" which does not work correctly before relocation in all cases. This patch removes this static variable and replaces it's functionality via a function that detects if the timer is already initialized.

2022-11-22timer: xilinx-timer: use timer_conv_64() to fix timer wrap aroundOvidiu Panait
Current xilinx_timer_get_count() implementation does not take into account the periodic 32-bit wrap arounds, as it directly returns the 32-bit counter register value. The roll-overs cause problems in the upper timer layers, as generic timer code expects an incrementing 64-bit value from get_count() to work correctly.

2022-11-02timer: add SP804 UCLASS timer driverAndre Przywara
The "Arm Ltd. Dual-Timer Module (SP804)" is a simple 32-bit count-down timer IP with interrupt functionality, and is used in some SoCs from various vendors. Add a simple DM compliant timer driver, to allow users of the SP804 to switch to DM_TIMER. This relies on the input clock to be accessible via the DM clock framework, which should be fine as we probably look at fixed-clock's here anyway. We re-program the control register in the probe() function, but keep the divider in place, in case this has been set to something on purpose before.

2021-12-27Finish conversion of CONFIG_SYS_CLK_FREQ to KconfigTom Rini
In order to finish moving this symbol to Kconfig for all platforms, we need to do a few more things. First, for all platforms that define this to a function, introduce CONFIG_DYNAMIC_SYS_CLK_FREQ, similar to CONFIG_DYNAMIC_DDR_CLK_FREQ and populate clock_legacy.h. This entails also switching all users from CONFIG_SYS_CLK_FREQ to get_board_sys_clk() and updating a few preprocessor tests. With that done, all platforms that define a value here can be converted to Kconfig, and a fall-back of zero is sufficiently safe to use (and what is used today in cases where code may or may not have this available). Make sure that code which calls this function includes <clock_legacy.h> to get the prototype. Signed-off-by: Tom Rini <[email protected]>
