2023-07-27mtd: Explicitly include correct DT includesRob Herring1-1/+0
The DT of_device.h and of_platform.h date back to the separate of_platform_bus_type before it was merged into the regular platform bus. As part of that merge prepping Arm DT support 13 years ago, they "temporarily" include each other. They also include platform_device.h and of.h. As a result, there's a pretty much random mix of those include files used throughout the tree. In order to detangle these headers and replace the implicit includes with struct declarations, users need to explicitly include the correct includes.

2023-04-11mtd: nand: Convert to platform remove callback returning voidUwe Kleine-König1-4/+2
The .remove() callback for a platform driver returns an int which makes many driver authors wrongly assume it's possible to do error handling by returning an error code. However the value returned is (mostly) ignored and this typically results in resource leaks. To improve here there is a quest to make the remove callback return void. In the first step of this quest all drivers are converted to .remove_new() which already returns void. Trivially convert this driver from always returning zero in the remove callback to the void returning variant.

2020-10-26mtd: rawnand: mxc: Move the ECC engine initialization to the right placeFabio Estevam1-12/+5
No ECC initialization should happen during the host controller probe. In fact, we need the probe function to call nand_scan() in order to: - identify the device, its capabilities and constraints (nand_scan_ident()) - configure the ECC engine accordingly (->attach_chip()) - scan its content and prepare the core (nand_scan_tail()) Moving these lines to mxcnd_attach_chip() fixes a regression caused by a previous commit supposed to clarify these steps. When moving the ECC initialization from probe() to attach(), get rid of the pdata usage to determine the engine type and let the core decide instead. Tested on a imx27-pdk board.

2018-06-19mtd: rawnand: mxc: set spare area size register explicitlyMartin Kaiser1-1/+4
The v21 version of the NAND flash controller contains a Spare Area Size Register (SPAS) at offset 0x10. Its setting defaults to the maximum spare area size of 218 bytes. The size that is set in this register is used by the controller when it calculates the ECC bytes internally in hardware. Usually, this register is updated from settings in the IIM fuses when the system is booting from NAND flash. For other boot media, however, the SPAS register remains at the default setting, which may not work for the particular flash chip on the board. The same goes for flash chips whose configuration cannot be set in the IIM fuses (e.g. chips with 2k sector size and 128 bytes spare area size can't be configured in the IIM fuses on imx25 systems). Set the SPAS register explicitly during the preset operation. Derive the register value from mtd->oobsize that was detected during probe by decoding the flash chip's ID bytes. While at it, rename the define for the spare area register's offset to NFC_V21_RSLTSPARE_AREA. The register at offset 0x10 on v1 controllers is different from the register on v21 controllers.
