The PLL rate tables are from the kernel https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?i...
That patch is three years old. That patch is for MX8M Mini clock, not for MX8M(Q).
You can use the abbreviated commit ID instead: 43cdaa1567ad3 ("clk: imx8mm: Move 1443X/1416X PLL clock structure to common place") But that seems to be the wrong commit.
That's the commit where the imx8m PLL frequency table is moved to a common file for use by all of the imx8m variants. The imx8mq linux driver does not even use the frequency tables so there is not a specific commit for it.
Isn't large part of this driver coming from these tables ?
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/log/drive...
When I said tables I was referring to the PLL frequency tables.
The driver is modelled after the u-boot imx8mm u-boot driver with register and mux updates from the imx8mq reference manual. Very little comes from the imx8mq kernel driver. Mainly I just verified mux naming and register offsets against that driver.
That reminds me that I need to send a kernel patch for the monitor muxes.
