Hi,
What is the SPI Clk operating Frequency for A64 Board's SPI in UEXT1 connector (SPI0)? I tried to check user manual as well as A64 SOC Data sheet, I couldn't find it.

Hi
I mean, max freq for SPI_CLK supported by A64, I tried to check that in A64 data sheet, there is no info on max clock speed of SPI_CLK. Can you please help?
