This driver supports clock controller of Sophgo CV18XX series SoC.
|
|
The driver require a 25MHz Oscillator to function generate clock.
|
|
It includes PLLs, common clock function and some vendor clock for
|
|
IPs of CV18XX series SoC

help
|
|
This driver supports the PLL clock controller on the
|
|
Sophgo SG2042 SoC. This clock IP uses three oscillators with
|
|
frequency of 25 MHz as input, which are used for Main/Fixed
|
|
PLL, DDR PLL 0 and DDR PLL 1 respectively.

help
|
|
This driver supports the Clock Generator on the
|
|
Sophgo SG2042 SoC. This clock IP depends on SG2042 PLL clock
|
|
because it uses PLL clocks as input.
|
|
This driver provides clock function such as DIV/Mux/Gate.

help
|
|
This driver supports the RP((Riscv Processors)) subsystem clock
|
|
controller on the Sophgo SG2042 SoC.
|
|
This clock IP depends on SG2042 Clock Generator because it uses
|
|
clock from Clock Generator IP as input.
|
|
This driver provides Gate function for RP.
