mtd: Explicitly include correct DT includes 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.

mtd: nand: Convert to platform remove callback returning void 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.

mtd: nand: mxic-ecc: Fix mxic_ecc_data_xfer_wait_for_completion() when irq is used wait_for_completion_timeout() and readl_poll_timeout() don't handle their return value the same way. wait_for_completion_timeout() returns 0 on time out (and >0 in all other cases) readl_poll_timeout() returns 0 on success and -ETIMEDOUT upon a timeout. In order for the error handling path to work in both cases, the logic against wait_for_completion_timeout() needs to be inverted.

mtd: nand: mxic-ecc: Support SPI pipelined mode Introduce the support for another possible configuration: the ECC engine may work as DMA master (pipelined) and move itself the data to/from the NAND chip into the buffer, applying the necessary corrections/computations on the fly. This driver offers an ECC engine implementation that must be instatiated from a SPI controller driver.

mtd: nand: mxic-ecc: Add Macronix external ECC engine support Some SPI-NAND chips do not support on-die ECC. For these chips, correction must apply on the SPI controller end. In order to avoid doing all the calculations by software, Macronix provides a specific engine that can offload the intensive work. Add Macronix ECC engine support, this engine can work in conjunction with a SPI controller and a raw NAND controller, it can be pipelined or external and supports linear and syndrome layouts. Right now the simplest configuration is supported: SPI controller external and linear ECC engine.
