Hi Lee, There has not been any comment on that series since a while and we have other series on hold, waiting for the first 4 patches to be taken. Could you have a look at those 4 patches and take them if you don't have any comment ?
Sorry for the delay, I have been on vacation. I'm not sure why why those patches are preventing the application of the remainder of the set. They are only documentation entries and I have Acked them already?

The EBI (External Bus Interface) is used to access external peripherals (NOR, SRAM, NAND, and other specific devices like ethernet controllers). Each device is assigned a CS line and an address range and can have its own configuration (timings, access mode, bus width, ...). This driver provides a generic DT binding to configure a device according to its requirements. For specific device controllers (like the NAND one) the SMC timings should be configured by the controller driver through the matrix and smc syscon regmaps. The first 4 patches introduce 2 syscon devices needed to configure the EBI bus, patch 5 and 6 adds support for the EBI bus, and the remaining patches declares the EBI related nodes in sama5d3 dts[i] files. Changes since v4: - fix inconsistencies in SMC and MATRIX registers definition - add missing compatible strings for at91sam9rl SoC - fix DT bindings documentation - replace "atmel,generic-dev" property by "atmel,specialized-logic" Changes since v3: - added AT91_MATRIX_USBPUCR_PUON definition - removed useless macros (those directly returning SoC specific register offsets) - use syscon_regmap_lookup_by_phandle instead of of_parse_phandle + syscon_node_to_regmap - drop AT91_EBICSA_REGFIELD and AT91_MULTI_EBICSA_REGFIELD macros Changes since v2: - minor fixes int DT bindings doc - fix SMC macros - make use of SMC macros defined in include/linux/mfd/syscon/atmel-smc.h Changes since v1: - almost everything :-) Boris Brezillon (11): mfd: syscon: Add atmel-matrix registers definition mfd: syscon: Add Atmel Matrix bus DT binding documentation mfd: syscon: Add atmel-smc registers definition mfd: syscon: Add Atmel SMC binding doc memory: add Atmel EBI (External Bus Interface) driver memory: atmel-ebi: add DT bindings documentation ARM: at91: select ATMEL_EBI when compiling a kernel for at91sam9 or sama5d3 ARM: at91/dt: add HSMC (Static Memory Controller) node in sama5d3 dtsi ARM: at91/dt: add matrix node in sama5d3 dtsi ARM: at91/dt: add EBI (External Bus Interface) node in sama5d3 dtsi ARM: at91/dt: add NOR definition in sama5d3xcm dtsi .../bindings/memory-controllers/atmel-ebi.txt | 155 ++++++ .../devicetree/bindings/mfd/atmel-matrix.txt | 24 + .../devicetree/bindings/mfd/atmel-smc.txt | 19 + arch/arm/boot/dts/sama5d3.dtsi | 93 ++++ arch/arm/boot/dts/sama5d3xcm.dtsi | 33 ++ arch/arm/mach-at91/Kconfig | 2 + drivers/memory/Kconfig | 11 + drivers/memory/Makefile | 1 + drivers/memory/atmel-ebi.c | 579 +++++++++++++++++++++ include/linux/mfd/syscon/atmel-matrix.h | 117 +++++ include/linux/mfd/syscon/atmel-smc.h | 173 ++++++ 11 files changed, 1207 insertions(+) create mode 100644 Documentation/devicetree/bindings/memory-controllers/atmel-ebi.txt create mode 100644 Documentation/devicetree/bindings/mfd/atmel-matrix.txt create mode 100644 Documentation/devicetree/bindings/mfd/atmel-smc.txt create mode 100644 drivers/memory/atmel-ebi.c create mode 100644 include/linux/mfd/syscon/atmel-matrix.h create mode 100644 include/linux/mfd/syscon/atmel-smc.h
