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: utils/timer: Simplify MTIMER synchronization

2021-08-14T03:37:42Z

We simplify MTIMER synchronization as follows: 1) Detect MTIMER devices with unique (or non-shared) MTIME register at boot-time 2) Select first MTIMER device with no associated HART as our reference MTIMER device 3) Only synchronize MTIMER devices with unique (or non-shared) MTIME register using reference MTIMER device 4) Directly update the MTIME register at time of synchronization because MTIME is a read/write register.
