The CPU peripherals on RTL83xx/RTL930x are connected to the CPU via the Lexra bus. This bus can provide a clock signal to these peripherals, but no clock driver is currently available. Instead, use a fixed-clock to provide the clock frequency, and update the dependent peripherals. Lexra bus clock frequencies: - RTL838x: 200MHz - RTL839x: 200MHz - RTL930x: 175MHz Signed-off-by: Sander Vanheule <sander@svanheule.net> -- v2: - Lexra clock defintion for RTL930x, update peripherals --- target/linux/realtek/dts-5.10/rtl838x.dtsi | 10 ++++++++-- target/linux/realtek/dts-5.10/rtl930x.dtsi | 11 +++++------ 2 files changed, 13 insertions(+), 8 deletions(-)
