2014-01-07mtd: lpc32xx_mlc: Remove unnecessary OOM messagesJingoo Han1-8/+2
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> Acked-by: Roland Stigge <stigge@antcom.de> Signed-off-by: Brian Norris <computersforpeace@gmail.com>
2014-01-03mtd: nand: lpc32xx_mlc: drop custom write_page callbackBrian Norris1-15/+1
This driver doesn't need its own custom chip->write_page callback; the only "custom" requirement is that this driver does not support subpage writes, which we can avoid using the NAND_NO_SUBPAGE_WRITE flag. With NAND_NO_SUBPAGE_WRITE, the default routine (nand_write_page()) should perform the equivalent operations.

2013-11-07mtd: nand: lpc32xx_mlc: Remove redundant of_match_ptrSachin Kamat1-1/+1
The data structure of_match_ptr() protects is always compiled in. Hence of_match_ptr() is not needed. Signed-off-by: Sachin Kamat <sachin.kamat@linaro.org> Signed-off-by: Brian Norris <computersforpeace@gmail.com>
2013-08-31mtd: nand: use dev_get_platdata()Jingoo Han1-1/+1
Use the wrapper function for retrieving the platform data instead of accessing dev->platform_data directly. Signed-off-by: Jingoo Han <jg1.han@samsung.com> Signed-off-by: Brian Norris <computersforpeace@gmail.com> Signed-off-by: David Woodhouse <David.Woodhouse@intel.com>
2013-08-05mtd: nand: lpc32xx: remove unnecessary platform_set_drvdata()Jingoo Han1-2/+0
The driver core clears the driver data to NULL after device_release or on probe failure, since commit 0998d0631001288a5974afc0b2a5f568bcdecb4d (device-core: Ensure drvdata = NULL when no driver is bound). Thus, it is not needed to manually clear the device driver data to NULL.

2013-05-18drivers/mtd/nand: don't check resource with devm_ioremap_resourceWolfram Sang1-5/+0
devm_ioremap_resource does sanity checks on the given resource. No need to duplicate this in the driver. Signed-off-by: Wolfram Sang <wsa@the-dreams.de>
2013-04-05mtd: nand: subpage write support for hardware based ECC schemesGupta, Pekon1-2/+2
This patch adds support for subpage (partial-page) writes when using hardware based ECC schemes. Advantages: (1) reduces storage overhead when using file-systems like UBIFS, which store LEB header at page-size granularity. (2) allows independent subpage writes, thereby increasing NAND storage efficiency for non-page aligned data. + updated cafe_nand and lpc32xx_mlc NAND drivers for change in chip->write_page interface.

2013-01-26mtd: Convert to devm_ioremap_resource()Thierry Reding1-5/+4
Convert all uses of devm_request_and_ioremap() to the newly introduced devm_ioremap_resource() which provides more consistent error handling. devm_ioremap_resource() provides its own error messages so all explicit error messages can be removed from the failure code paths.

2012-09-29mtd: lpc32xx_mlc: Cleanup after DT-only conversionRoland Stigge1-28/+18
The LPC32xx's DT-only conversion of the MLC NAND driver makes NAND config via platform_data obsolete. Dropped by this patch. Further, the driver really needs CONFIG_OF, which is already reflected by the dependency on ARCH_LPC32XX which depends on CONFIG_OF. So also dropping CONFIG_OF ifdefs. There is still platform_data necessary to supply the dma_filter callback for the dma engine. This is a completely different data structure than the old platform_data for NAND config, so renaming some old "pdata" variable to "ncfg" to prevent confusion with the new platform data.
