The Realtek SOCs of the RTL83XX and RTL93XX series have at least 5 known
|
|
timers with corresponding interrupt lines . Their speed is derived from the
|
|
Lexra Bus (LXB) by dividers. Each timer has a block of 4 control registers in
|
|
the address range 0xb800xxxx with following start offsets.
|
|
|
|
RTL83XX: 0x3100, 0x3110, 0x3120, 0x3130, 0x3140
|
|
RTL93XX: 0x3200, 0x3210, 0x3220, 0x3230, 0x3240
