2022-08-16memory: dfl-emif: Update the dfl emif driver support revision 1Debarati Biswas1-5/+57
The next generation (revision 1) of the DFL EMIF feature device requires support for more than 4 memory banks. It does not support the selective clearing of memory banks. A capability register replaces the previous control register, and contains a bitmask to indicate the presence of each memory bank. This bitmask aligns with the previous control register bitmask that served the same purpose. The control and capability registers are treated like a C Union structure in order to support both the new and old revisions of the EMIF device.

While the smi-common configuration is specific to this SoC, on the LARB side, this is similar to MT8173, in the sense that it doesn't need the port in LARB, and the register layout is also compatible with that one, which makes us able to fully reuse the smi-larb platform data struct that was introduced for MT8173.

Add support for logging memory controller errors on Tegra186, Tegra194 and Tegra234. On these SoCs, interrupts can occur on multiple channels. Add support required to read the status of interrupts across multiple channels, log and clear them. Also add new interrupts supported on these SoCs.

From Tegra186 onwards, the memory controller supports multiple channels. Add support for mapping the address spaces of these channels and specify the number of channels supported by Tegra186, Tegra194 and Tegra234. In case of old bindings, channels won't be present. If channels are not present then print a warning and continue so that backward compatibility will be preserved in driver. During error interrupts from memory controller, appropriate registers from these channels need to be accessed for logging error info.

2022-04-29memory: omap-gpmc: Allow building as a moduleRoger Quadros2-21/+24
Allow OMAP_GPMC to be built as a module. When building this driver as a module, the symbol 'of_default_bus_match_table' will not be found as it is not being exported. The of_match_node() call is redundant anyways as of_platform_default_populate() already takes care of matching with 'of_default_bus_match_table'. So get rid of that call. This will also resolve the module build failure. Move compatible match table to the end where it is usually expected.

So far for armv7 TI platforms, GPMC was being selected by arch/arm/mach-* architecture Kconfig files. For K3 platforms, GPMC is no longer required for basic boot and cannot be always enabled by default by mach- Kconfig. We need a way for user (or board defconfig) to enable it if required so make OMAP_GPMC Kconfig option always visible. Drop COMPILE_TEST as build fails if IRQ_DOMAIN is not enabled.

2022-04-21memory: renesas-rpc-if: Fix HF/OSPI data transfer in Manual ModeGeert Uytterhoeven1-14/+46
HyperFlash devices fail to probe: rpc-if-hyperflash rpc-if-hyperflash: probing of hyperbus device failed In HyperFlash or Octal-SPI Flash mode, the Transfer Data Enable bits (SPIDE) in the Manual Mode Enable Setting Register (SMENR) are derived from half of the transfer size, cfr. the rpcif_bits_set() helper function. However, rpcif_reg_{read,write}() does not take the bus size into account, and does not double all Manual Mode Data Register access sizes when communicating with a HyperFlash or Octal-SPI Flash device. Fix this, and avoid the back-and-forth conversion between transfer size and Transfer Data Enable bits, by explicitly storing the transfer size in struct rpcif, and using that value to determine access size in rpcif_reg_{read,write}(). Enforce that the "high" Manual Mode Read/Write Data Registers (SM[RW]DR1) are only used for 8-byte data accesses. While at it, forbid writing to the Manual Mode Read Data Registers, as they are read-only.

Commit 3e25f800afb8 ("memory: fsl_ifc: populate child devices without relying on simple-bus") was trying to replace the "simple-bus" compatible with explicit bus populate in the driver.
