2015-05-20mtd: Allow compile test of GPIO consumers if !GPIOLIBGeert Uytterhoeven1-1/+1
The GPIO subsystem provides dummy GPIO consumer functions if GPIOLIB is not enabled. Hence drivers that depend on GPIOLIB, but use GPIO consumer functionality only, can still be compiled if GPIOLIB is not enabled. Relax the dependency on GPIOLIB if COMPILE_TEST is enabled, where appropriate.

2015-05-15mtd: nand: add NAND driver "library" for Broadcom STB NAND controllerBrian Norris1-0/+8
This core originated in Set-Top Box chips (BCM7xxx) but is used in a variety of other Broadcom chips, including some BCM63xxx, BCM33xx, and iProc/Cygnus. It's been used only on ARM and MIPS SoCs, so restrict it to those architectures. There are multiple revisions of this core throughout the years, and almost every version broke register compatibility in some small way, but with some effort, this driver is able to support v4.0, v5.0, v6.x, v7.0, and v7.1. It's been tested on v5.0, v6.0, v6.1, v7.0, and v7.1 recently, so there hopefully are no more lurking inconsistencies. This patch adds just some library support, on which platform drivers can be built.

2015-02-05mtd: kconfig: replace PPC_OF with PPCKevin Hao1-1/+1
The PPC_OF is a ppc specific option which is used to mean that the firmware device tree access functions are available. Since all the ppc platforms have a device tree, it is aways set to 'y' for ppc. So it makes no sense to keep a such option in the current kernel. Replace it with PPC. Signed-off-by: Kevin Hao <haokexin@gmail.com> Signed-off-by: Brian Norris <computersforpeace@gmail.com>
2014-11-04mtd: nand: gpio: improve comments about GPIO assisted operationGerhard Sittig1-2/+4
The drivers/mtd/nand/gpio.c driver does not GPIO bitbang the complete NAND protocol, but instead is GPIO _assisted_ -- a memory mapped interface communicates commands and data, and only few control signals are connected to GPIO pins. Expand comments in the driver source and in the Kconfig description to better reflect the very nature of the driver. The previous text could be mistaken for complete GPIO bitbanging.

It wasn't selecting CONFIG_MEMORY. So we never built drivers/memory/fsl_ifc.o and so we have nothing to link the above symbols against. Since the goal of the original commit was to relocate the driver to an arch independent location, it only makes sense to relocate the Kconfig setting there as well. But that alone won't fix the build failure; for that we ensure whoever selects FSL_IFC also selects MEMORY.

The MTD subsystem has its own small museum of ancient NANDs in a form of the CONFIG_MTD_NAND_MUSEUM_IDS configuration option. The museum contains stone age NANDs with 256 bytes pages, as well as iron age NANDs with 512 bytes per page and up to 8MiB page size. It is with great sorrow that I inform you that the museum is being decommissioned. The MTD subsystem is out of budget for Kconfig options and already has too many of them, and there is a general kernel trend to simplify the configuration menu. We remove the stone age exhibits along with closing the museum, but some of the iron age ones are transferred to the regular NAND depot. Namely, only those which have unique device IDs are transferred, and the ones which have conflicting device IDs are removed.

The Denali controller can also be found in SoC devices attached to a simple bus. Move the PCI specific parts into denali_pci so that we can add a denali_dt that uses the same driver but for a device tree driver instead of a PCI based device.

2012-11-05ARM: plat-nomadik: move MTU, kill plat-nomadikLinus Walleij1-1/+1
This moves the MTU timer driver from arch/arm/plat-nomadik to drivers/clocksource and moves the header file to the platform_data directory. As this moves the last file being compiled to an object out of arch/arm/plat-nomadik, we have to "turn off the light" and delete the plat-nomadik directory, because it is not allowed to have an empty Makefile in a plat-* directory. This is probably also a desired side effect of depopulating the arch/arm directory of drivers. Luckily we have just deleted all the <plat/*> include files prior to this so by moving the last one we may delete the directory. After this all the Ux500 and Nomadik device drivers live outside of the arch/arm hierarchy.

2012-09-29mtd: docg4: add missing HAS_IOMEM dependencyPeter Huewe1-1/+1
While building an allyesconfig for UML I received this error message(s): drivers/mtd/nand/docg4.c: In function 'probe_docg4': drivers/mtd/nand/docg4.c:1272:2: error: implicit declaration of function 'ioremap' [-Werror=implicit-function-declaration] drivers/mtd/nand/docg4.c:1272:10: warning: assignment makes pointer from integer without a cast [enabled by default] drivers/mtd/nand/docg4.c:1327:2: error: implicit declaration of function 'iounmap' [-Werror=implicit-function-declaration] which is caused by the missing implementations on UML.

Just as Artem suggested: "Both UBI and JFFS2 are able to read verify what they wrote already. There are also MTD tests which do this verification. So I think there is no reason to keep this in the NAND layer, let alone wasting RAM in the driver to support this feature. Besides, it does not work for sub-pages and many drivers have it broken. It hurts more than it provides benefits." So kill MTD_NAND_VERIFY_WRITE entirely.

With device tree support in place, we should not use IMX_HAVE_PLATFORM_MXC_NAND as a dependency for selecting the mxc_nand driver.
