<tokyovigilante> loki666: paulk: thanks, I think this iteration of the TCON node may have been optimised for passing the kernel linter, not for correctness.

<apritzel> wens: I have this for the CPU clocks, please feel free to complete and fix this: https://gist.github.com/apritzel/11db4ccd644d4d0bf1d72088a94587c5
<apritzel> for the MCU clocks, I grabbed the BSP code and tried to fix this, but didn't get very far. It's probably still the best approach

<parthiban> apritzel: Thanks for the hint about address mapping for 4GB. Rank for the issue and now managed to boot kernel with 4GB. Still testing with stress-ng fails to work, but mtest passes.

<parthiban> Also to add, DDR Controller used in A133 matches exactly with the one in STM32MP1/2.
<parthiban> Should the kernel be passed with memory node in dts to know the exact DRAM size? or u-boot passes it? Am still reading the code.
<apritzel> U-Boot fills in the DT memory node, in generic code, just a sec ....
<parthiban> cat /proc/device-tree/memory/reg doesn't have anything filled. So am not sure
<apritzel> boot/fdt_support.c:fdt_fixup_memory_banks()
<apritzel> parthiban: if you get this far, it must be in there. How did you check? reg is binary content, so if you just "cat" it, you won't see much on the terminal. Use "hexdump -C reg"
<apritzel> also, please use /sys/firmware/devicetree/base instead of the deprecated /proc/device-tree directory
<apritzel> parthiban: is there documentation available for this STM32 DRAM controller?
<parthiban> It's public in ST's page.
<parthiban> Chapter 14: DDR3L/DDR4/LPDDR4 controller (DDRCTRL)

<paulk> parthiban: yes the DDR controller is a synopsys mctl2
<parthiban> but still the PHY didn't match.
<paulk> uMCTL2* sorry
<paulk> indeed the PHY is a separate block, connected via DFI interface, which allows to mix and match between different vendors
<paulk> the DDR controller is also used in TI jacinto 7 and imx8 which also have docs available
<paulk> maybe you can get lucky and find the same phy there ;)
<parthiban> Thanks, I will have a look. From Cody's initial work it didn't match with any I think https://linux-sunxi.org/A133/DRAMC

<BroderTuck> Noticed something on the Wifi page on the wifi. The aw859 is listed but not the aw869 found on for example the walnutpi that junari has. Would appreciate if it could be added with its sdio id
