KernelVersion: 6.20
Contact: Jinlong Mao <jinlong.mao@oss.qualcomm.com>, Tao Zhang <tao.zhang@oss.qualcomm.com>, Jie Gan <jie.gan@oss.qualcomm.com>
Description:
(RW) Set mode the of the syncr counter.
mode 0 - COUNT[11:0] value represents the approximate number of bytes moved between two ASYNC packet requests
mode 1 - the bits COUNT[11:7] are used as a power of 2. for example, we could insert an async packet every 8K
data by writing a value 13 to the COUNT[11:7] field.
