2018-04-29mtd: rawnand: gpmi: drop dma_ops_typeSascha Hauer3-55/+23
The GPMI nand driver puts dma_ops_type in its private data struct. Based on the ops type the DMA callback handler unmaps previously mapped buffers. Instead of unmapping the buffers in the DMA callback handler, do this in the caller directly which waits for the DMA transfer to finish. This makes the whole dma_ops_type mechanism unnecessary.

2018-04-29mtd: rawnand: add a way to pass an ID table with nand_scan()Miquel Raynal1-4/+6
As part of the work of migrating all the drivers to nand_scan(), and because nand_scan() does not provide a way to pass an ID table, rename the function nand_scan_with_ids() and add a third parameter to give a flash ID table (like what was done with nand_scan_ident()). Create a nand_scan() helper that is just a wrapper of nand_scan_with_ids(), passing NULL as the ID table. This way a controller drivers can continue using nand_scan() transparently.

An error after nand_scan_tail() should trigger a nand_cleanup(). The helper mtd_device_parse_register() returns an error code that should be checked and nand_cleanup() called accordingly. However, in this driver, fsl_ifc_chip_remove() which is called upon error already triggers a nand_release() which is wrong, because a nand_release() should be triggered only if an mtd_register() succeeded.

2018-04-29mtd: rawnand: diskonchip: Replace mdelay with usleep_range in doc_probeJia-Ju Bai1-2/+2
doc_probe() is never called in atomic context. doc_probe() is only called by init_nanddoc(), which is only set as a parameter of module_init(). This function is not called in atomic context. Despite never getting called from atomic context, doc_probe() calls mdelay() to busily wait. This is not necessary and can be replaced with usleep_range() to avoid busy waiting. This is found by a static analysis tool named DCNS written by myself. And I also manually check it.

2018-04-26mtd: rawnand: davinci: don't acquire and enable clockSekhar Nori1-24/+1
NAND itself is an asynchronous interface, it does not have any clock input. DaVinci NAND driver acquires clock for AEMIF (asynchronous external memory interface) which is an on-chip IP to which NAND is connected. The same clock is also enabled in AEMIF driver (either present drivers/memory or from machine code for some older platforms). AEMIF timing must be initialized before NAND can be accessed. This ensures that AEMIF clock is enabled too. Remove the superfluous clock acquisition and enable in DaVinci NAND driver. Tested on K2L, K2HK, K2E, DA850 EVM, DA850 LCDK in device-tree boot and DM644x EVM in legacy boot.

When opening a device with write access, ubiblock_open returns an error code. Currently, this error code is -EPERM, but this is not the right value. The open function for other block devices returns -EROFS when opening read-only devices with FMODE_WRITE set. When used with dm-verity, the veritysetup userspace tool is expecting EROFS, and refuses to use the ubiblock device. Use -EROFS for ubiblock as well. As a result, veritysetup accepts the ubiblock device as valid.

Currently on a imx6sx-sdb board, which has two SPI NOR chips connected to QSPI2 the following output from /proc/mtd is seen: dev: size erasesize name mtd0: 01000000 00010000 "21e4000.qspi" mtd1: 01000000 00010000 "21e4000.qspi" Attempts to partition them on the kernel command line result in both chips with identical (and identically named) partitions, which is an inconvenient behavior. Assign a different mtd->name for each mtd device to avoid this problem. After this change the output from /proc/mtd becomes: dev: size erasesize name mtd0: 01000000 00010000 "21e4000.qspi-0" mtd1: 01000000 00010000 "21e4000.qspi-1" In order to keep mtdparts compatibility keep the mtd->name unchanged when a single SPI NOR is present.

An error after nand_scan_tail() should trigger a nand_cleanup(). The helper mtd_device_parse_register() returns an error code that should be checked and nand_cleanup() called accordingly.

This mode is not used by any existing setup and should not be used because it overwrites the BBMs. Let's just remove it before someone starts using it.

2018-03-29mtd: rawnand: marvell: Fix clock resource by adding a register clockGregory CLEMENT1-6/+28
On Armada 7K/8K we need to explicitly enable the register clock. This clock is optional because not all the SoCs using this IP need it but at least for Armada 7K/8K it is actually mandatory. The binding documentation is updated accordingly. Signed-off-by: Gregory CLEMENT <gregory.clement@bootlin.com> Signed-off-by: Boris Brezillon <boris.brezillon@bootlin.com>

2018-03-29mtd: physmap_of: update struct map_info's swap as per map requirementPrabhakar Kushwaha1-0/+6
It is not necessary for all device's maps to be CFI_HOST_ENDIAN. Maps device can be Big endian or little endian. Currently it is being taken care using CONFIG_MTD_CFI_LE_BYTE_SWAP or CONFIG_MTD_CFI_BE_BYTE_SWAP i.e. compile time. Now update struct map_info's swap field based on device characteristics defined in device tree.

In the commit 2c77c57d22adb ("mtd: move code adding master MTD out of mtd_add_device_partitions()") behavior of mtd_device_parse_register() has very slightly changed. It's a pretty non-significant order change to match updated function behavior.
