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: Add fdt_parse_clint_node() function

2020-05-23T05:06:46Z

We add fdt_parse_clint_node() function which will be used by fdt_ipi_clint and fdt_timer_clint drivers to parse CLINT details from DT node. Signed-off-by: Anup Patel Reviewed-by: Atish Patra

lib: utils: Allow CLINT functions to be used for multiple CLINTs

2020-05-23T05:06:43Z

We extend CLINT cold init function to have a "struct clint_data *" parameter pointing to CLINT details. This allows platforms to use CLINT functions for multiple CLINT instances. When multiple CLINTs are present, the platform can also provide one of the CLINT as reference CLINT for other CLINTs. This will help CLINTs to sync their time value with reference CLINT using a time_delta computed in warm init function. 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
