lib: sbi: Add generic timer delay loop function

2021-09-26T14:22:15Z

We now have frequency of the timer device provided by the platform support so we can emulate desired delay using a loop where the number loop iterations are based on timer frequency. This patch provides sbi_timer_delay_loop() for above purpose. Signed-off-by: Anup Patel Reviewed-by: Bin Meng Reviewed-by: Xiang W

lib: sbi: Add timer frequency to struct sbi_timer_device

2021-09-26T14:22:10Z

Generic mdelay() and udelay() functions can be provided by the sbi_timer framework if timer frequency is available in the timer instance provided by the platform support or timer driver. This patch adds timer frequency (timer_freq) member in the struct sbi_timer_device for above purpose. Signed-off-by: Anup Patel Reviewed-by: Bin Meng 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: Add timer exit API

2020-01-07T06:40:55Z

We add sbi_timer_exit() API for OpenSBI exit path handling in sbi_exit() implementation. Signed-off-by: Anup Patel Reviewed-by: Atish Patra

lib: Emulate HTIMEDELTA CSR for platforms not having TIME CSR

2019-09-30T10:06:14Z

For platforms not having TIME CSR, we trap-n-emulate TIME CSR read/write in OpenSBI. Same rationale applies to HTIMEDELTA CSR as well so we trap-n-emulate HTIMEDELTA CSR for platforms not having TIME CSR. Signed-off-by: Anup Patel

lib: Remove target_hart and hartid parameter from TIMER callbacks

2019-01-23T03:09:26Z

The target_hart and hartid paramter of TIMER callbacks is not required because it always current hartid which can be obtained using sbi_current_hartid() API. Signed-off-by: Anup Patel

lib: Simplify sbi_platform timer_init() hooks

2018-12-27T04:05:09Z

Instead of having separate timer_init() hooks for cold and warm boot, this patch updates struct sbi_platform to have just one timer_init() hook. The type of boot (cold or warm) is now a boolean flag parameter for the updated timer_init() hook. Signed-off-by: Anup Patel
