lib: utils/timer: Use fdt_driver for initialization

2024-11-28T12:27:20Z

The timer driver subsystem does not need any extra data, so it can use `struct fdt_driver` directly. The generic fdt_timer_init() performs a best-effort initialization of all matching DT nodes. Signed-off-by: Samuel Holland Reviewed-by: Anup Patel

treewide: Make carray arrays const and NULL-terminated

2024-11-28T11:39:17Z

This allows the compiler to generate significantly better code, because it does not have to maintain either the loop counter or loop limit. Plus there are half as many symbols to relocate. This also simplifies passing carray arrays to helper functions. Signed-off-by: Samuel Holland Reviewed-by: Anup Patel

platform: Drop timer warm init and exit hooks

2024-11-05T12:09:31Z

Now that driver lifecycle is managed from within the SBI timer core, platforms need only to initialize the driver once during cold init. Remove the remaining platform hooks that are no longer used. Signed-off-by: Samuel Holland Reviewed-by: Anup Patel

lib: utils/timer: Constify FDT pointers in parsing functions

2024-08-24T07:32:48Z

Indicate that none of these functions modify the devicetree by constifying the parameter type. Signed-off-by: Samuel Holland Reviewed-by: Andrew Jones Reviewed-by: Anup Patel

lib: utils/timer: Skip initialize timer when dt is not enabled

2024-06-13T13:01:40Z

When the dt node has a status property and the value is not ok or okay, skip initializing timer. Signed-off-by: Xiang W Reviewed-by: Anup Patel

lib: utils: Improve fdt_timer

2023-05-26T07:17:22Z

Remove dummy driver. Optimize fdt_timer_cold_init to exit the loop early. Signed-off-by: Xiang W Reviewed-by: Anup Patel

lib: utils/timer: Generate FDT timer driver list at compile-time

2022-05-13T03:56:20Z

Instead of having FDT timer driver list hard-coded in the C source, we generate it using carray.sh at compile-time. Signed-off-by: Anup Patel Reviewed-by: Atish Patra

include: sbi_utils: Introduce an helper to get fdt base address

2021-11-02T05:53:16Z

This simply adds an helper to get fdt address which is more explicit than sbi_scratch_thishart_arg1_ptr. Signed-off-by: Alexandre Ghiti Reviewed-by: Xiang W Reviewed-by: Anup Patel

lib: utils/timer: Add FDT based ACLINT MTIMER driver

2021-06-24T04:09:53Z

We add a new FDT based ACLINT MTIMER driver which works for both CLINT device and standalone ACLINT MTIMER device. Signed-off-by: Anup Patel Reviewed-by: Bin Meng Reviewed-by: Xiang W

lib: utils: Try other FDT drivers when we see SBI_ENODEV

2021-05-24T10:19:21Z

We should try other FDT drivers when we see SBI_ENODEV returned by cold_init() of FDT driver. Signed-off-by: Anup Patel Reviewed-by: Atish Patra Reviewed-by: Xiang W
