| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The MR25 family doesn't support JEDEC, so they need explicit mentioning in the list of supported spi IDs. This makes it possible to add these using for example: compatible = "everspin,mr25h40"; There was already an entry for mr25h256. Move that one out of the "keep for compatibility" section and put in a new group for Everspin MRAMs. Signed-off-by: Uwe Kleine-König <u.kleine-koenig@pengutronix.de> Acked-by: Rob Herring <robh@kernel.org> Signed-off-by: Cyrille Pitchen <cyrille.pitchen@atmel.com>

* mtd: nand: Add an option to maximize the ECC strengthBoris Brezillon2016-09-231-0/+9
| | | | | | | | | | | | | | | | | | | The generic NAND DT bindings allows one to tweak the ECC strength and step size to their need. It can be used to lower the ECC strength to match a bootloader/firmware config, but might also be used to get a better reliability. In the latter case, the user might want to use the maximum ECC strength without having to explicitly calculate the exact value (this value not only depends on the OOB size, but also on the NAND controller, and can be tricky to extract). Add a generic 'nand-ecc-maximize' DT property and the associated NAND_ECC_MAXIMIZE flag, to let ECC controller drivers select the best ECC strength and step-size on their own.

Versatile flash chips are actually just standard CFI chips, but they have one or two bits in a system controller to control VPP and write protection.

| | | | | | | | | | | | | | | | | | Starting with the SAMA5D2, there is a new revision of the Atmel PMECC controller that can correct 32 bits in each sector. This controller is not 100% compatible with the previous revision that corrected a maximum of 24 bits by sector, as some register addresses overlap. Using information from the device tree, we can configure the driver to work with both versions.

Particularly, there was a proposal to use this node for the AFS parser too. It can pose a (small) problem to try to differentiate the following nodes: // using binding as currently specified partitions { #address-cells = <x>; #size-cells = <y>; partition@0 { ...; }; }; and // proposed future binding partitions { compatible = "arm,arm-flash-structure"; }; It's especially difficult if other uses of this node start having subnodes. So, since the "partitions" node is new in v4.4, let's fixup the binding before release so that it requires a compatible property, so it's much clearer to distinguish. e.g.: // proposed partitions { compatible = "fixed-partitions"; #address-cells = <x>; #size-cells = <y>; partition@0 { ...; }; }; [1] Subject: "mtd: create a partition type device tree binding" http://lkml.kernel.org/g/20151113220039.GA74382@google.com http://lists.infradead.org/pipermail/linux-mtd/2015-November/063355.html http://lists.infradead.org/pipermail/linux-mtd/2015-November/063364.html Cc: Michal Suchanek <hramrach@gmail.com> Signed-off-by: Brian Norris <computersforpeace@gmail.com> Acked-by: Rob Herring <robh@kernel.org>
