2014-03-10mtd: delete non-required instances of include <linux/init.h>Paul Gortmaker
None of these files are actually using any __init type directives and hence don't need to include <linux/init.h>. Most are just a left over from __devinit and __cpuinit removal, or simply due to code getting copied from one driver to the next.

2014-01-07mtd: nand-gpio: don't waste memory for OF failureBrian Norris
We shouldn't try to allocate a resource until we're sure the of_property_read_u64() call didn't fail. This is especially important if we use this code for both CONFIG_OF and !CONFIG_OF builds, since of_property_read_u64() will always return -ENOSYS for !CONFIG_OF.

2014-01-07mtd: nand-gpio: Remove unnecessary OOM messagesJingoo Han
The site-specific OOM messages are unnecessary, because they duplicate the MM subsystem generic OOM message. Signed-off-by: Jingoo Han <jg1.han@samsung.com> Signed-off-by: Brian Norris <computersforpeace@gmail.com>

2012-12-13mtd: nand/gpio: use io{read,write}*_rep accessorsMatthew Leach
The {read,write}s{b,w,l} operations are not defined by all architectures and are being removed from the asm-generic/io.h interface. This patch replaces the usage of these string functions in the mtd gpio accessors with io{read,write}{8,16,32}_rep calls instead.

2012-09-29mtd: kill MTD_NAND_VERIFY_WRITEHuang Shijie
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.

2012-01-09mtd: gpio-nand: add device tree bindingsJamie Iles
Add device tree bindings so that the gpio-nand driver may be instantiated from the device tree. This also allows the partitions to be specified in the device tree. v7: - restore runtime device tree/non device tree detection v6: - convert to mtd_device_parse_register() v5: - fold dt config helpers into a single gpio_nand_of_get_config() v4: - get io sync address from gpio-control-nand,io-sync-reg property rather than a resource - clarified a few details in the binding v3: - remove redundant cast and a couple of whitespace/naming changes v2: - add CONFIG_OF guards for non-dt platforms - compatible becomes gpio-control-nand - clarify some binding details Signed-off-by: Jamie Iles <jamie@jamieiles.com> Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@linux.intel.com> Signed-off-by: David Woodhouse <David.Woodhouse@intel.com>
