2025-11-22memory: tegra186-emc: Fix missing put_bpmpJon Hunter
Commit a52ddb98a674 ("memory: tegra186-emc: Simplify and handle deferred probe with dev_err_probe()") accidently dropped a call to 'put_bpmp' to release a handle to the BPMP when getting the EMC clock fails. Fix this by restoring the 'goto put_bpmp' if devm_clk_get() fails.

Add support to enable Memory Controller (MC) and External Memory Controller (EMC) drivers for Tegra264. The nodes for MC and EMC are mostly the same as Tegra234 but differ in number of channels and interrupt numbers. The patch also adds the bandwidth manager definitions required for Tegra264 and uses them to populate the memory client table.

2025-05-16memory: omap-gpmc: Switch to irq_domain_create_linear()Jiri Slaby (SUSE)
irq_domain_add_linear() is going away as being obsolete now. Switch to the preferred irq_domain_create_linear(). That differs in the first parameter: It takes more generic struct fwnode_handle instead of struct device_node. Therefore, of_fwnode_handle() is added around the parameter. Note some of the users can likely use dev->fwnode directly instead of indirect of_fwnode_handle(dev->of_node). But dev->fwnode is not guaranteed to be set for all, so this has to be investigated on case to case basis (by people who can actually test with the HW).

2025-05-07memory: Add STM32 Octo Memory Manager driverPatrice Chotard
Octo Memory Manager driver (OMM) manages: - the muxing between 2 OSPI busses and 2 output ports. There are 4 possible muxing configurations: - direct mode (no multiplexing): OSPI1 output is on port 1 and OSPI2 output is on port 2 - OSPI1 and OSPI2 are multiplexed over the same output port 1 - swapped mode (no multiplexing), OSPI1 output is on port 2, OSPI2 output is on port 1 - OSPI1 and OSPI2 are multiplexed over the same output port 2 - the split of the memory area shared between the 2 OSPI instances. - chip select selection override. - the time between 2 transactions in multiplexed mode. - check firewall access.

Add support for RZ/G3E xSPI. Compared to RPC-IF, it can support writes on memory-mapped area. Introduce struct rpcif_impl for holding the function pointers and data to handle the differences between xspi and rpc-if interface.
