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

lib: sbi: Simplify timer platform operations

2021-04-28T11:30:49Z

Instead of having timer_value(), timer_event_start(), and timer_event_stop() callbacks in platform operations, it will be much simpler for timer driver to directly register these operations as device to the sbi_timer implementation. Signed-off-by: Anup Patel Reviewed-by: Alistair Francis

lib: utils/timer: Initialize all matching timer DT nodes

2020-05-23T05:06:53Z

We can have multiple matching DT nodes of the same FDT timer driver so in this case we should call cold_init() for all matching DT nodes instead of just first matching DT node. Signed-off-by: Anup Patel Reviewed-by: Atish Patra

lib: utils: Extend fdt_find_match() Implementation

2020-05-23T05:06:33Z

We extend fdt_find_match() implementation by adding node offset parameter which represents the first node to match from. The improved fdt_find_match() can be used to find multiple match nodes. Signed-off-by: Anup Patel Reviewed-by: Atish Patra

lib: utils: Add simple FDT timer framework

2020-05-01T04:27:55Z

We add simple timer framework which will select and use timer driver based on details in FDT passed by previous booting stage. Signed-off-by: Anup Patel Reviewed-by: Atish Patra
