Its main purposes are: - to translate AXI transactions into the appropriate external device protocol - to meet the access time requirements of the external devices All external devices share the addresses, data and control signals with the controller. Each external device is accessed by means of a unique Chip Select. The FMC2 performs only one access at a time to an external device. Changes in v5: - NAND: - do not display errors if the driver is deferred. - look at the parent compatible string to match what we expect. - bindings: - add Rob reviewed-by tag on patch 3. - fix indent descriptions. - add new NFC compatible string to handle reg number of entries. Changes in v4: - bindings: - fix filename: st,stm32-fmc2-ebi.yaml Changes in v3: - NAND: - rename labels used on errors - add in the commit log the reason to increase FMC2_TIMEOUT_MS (patch 3) - add Miquel reviewed-by tag (patches 2/4/5/9) - EBI: - move in memory folder - merge MFD and BUS drivers to avoid a MFD driver - bindings: - pattern name has been modified - vendor properties have been modified - s/_/-/ - add unit suffix (-ns) on timing properties Christophe Kerello (6): mtd: rawnand: stm32_fmc2: do not display errors if the driver is deferred dt-bindings: mtd: update STM32 FMC2 NAND controller documentation dt-bindings: memory-controller: add STM32 FMC2 EBI controller documentation memory: stm32-fmc2-ebi: add STM32 FMC2 EBI controller driver mtd: rawnand: stm32_fmc2: use regmap APIs mtd: rawnand: stm32_fmc2: get resources from parent node .../memory-controllers/st,stm32-fmc2-ebi.yaml | 252 ++++ .../bindings/mtd/st,stm32-fmc2-nand.yaml | 83 +- drivers/memory/Kconfig | 10 + drivers/memory/Makefile | 1 + drivers/memory/stm32-fmc2-ebi.c | 1206 ++++++++++++++++++++ drivers/mtd/nand/raw/Kconfig | 1 + drivers/mtd/nand/raw/stm32_fmc2_nand.c | 311 ++--- 7 files changed, 1688 insertions(+), 176 deletions(-) create mode 100644 Documentation/devicetree/bindings/memory-controllers/st,stm32-fmc2-ebi.yaml create mode 100644 drivers/memory/stm32-fmc2-ebi.c
