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!

Ok, I understand. DT changes are still under review [1] and are not yet merged in 5.18-rc6. Sorry for the noise.

Hi, TI's AM64 SoC contains one GPMC module. Add driver support for it. cheers, -roger Changelog: v4 - move compatible match table to header file so it can be used by GPMC driver even when NAND driver is not enabled or as a module. GPMC driver is always enabled as built-in. - Select OMAP_GPMC driver from MTD_NAND_OMAP2 driver config as OMAP_GPMC is not essential for ARCH_K3 boot. v3 - use compatible match table for checking for NAND controller node in GPMC driver. v2 - update DT binding doc to make reg-names and power-domains property required only for specific SoC.
