What's the status of the GPMC interface on K3 architecture, especially for AM65, AM62 and other Jacinto 7 CPU devices ? TI currently don't recommend to use it for now even if there are still some GPMC use case with FPGA devices: https://e2e.ti.com/support/processors-group/processors/f/processors-forum/994191/am6442-am64x-gpmc-support This patch series add omap-gpmc support for AM64 Soc but as of kernel 5.18-rc2, there is no devicetree using ti,am64-gpmc. This patch seems missing (at least): https://git.ti.com/cgit/ti-linux-kernel/ti-linux-kernel/commit/?h=ti-linux-5.10.y&id=55c102a75d399896c7396229cd687bf97afb5cf6 Thanks!
