| * mtd: spi-nor / spi / MFD: Convert intel-spi to SPI MEMMark Brown2022-02-156-1181/+0
| |\ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Merge series from Mika Westerberg <mika.westerberg@linux.intel.com>: Based on discussion on the patch I sent some time ago here: http://lists.infradead.org/pipermail/linux-mtd/2021-June/086867.html it turns out that the preferred way to deal with the SPI flash controller drivers is through SPI MEM which is part of Linux SPI subsystem. This series does that for the intel-spi driver. This also renames the driver to follow the convention used in the SPI subsystem. The first patch improves the write protection handling to be slightly more safer. The following two patches do the conversion itself. Note the Intel SPI flash controller only allows commands such as read, write and so on and it internally uses whatever addressing etc. it figured from the SFDP on the flash device. base-commit: e783362eb54cd99b2cac8b3a9aeac942e6f6ac07

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The preferred way to implement SPI-NOR controller drivers is through SPI subsubsystem utilizing the SPI MEM core functions. This converts the Intel SPI flash controller driver over the SPI MEM by moving the driver from SPI-NOR subsystem to SPI subsystem and in one go make it use the SPI MEM functions. The driver name will be changed from intel-spi to spi-intel to match the convention used in the SPI subsystem.

| * | spi: make remove callback a void functionUwe Kleine-König2022-02-094-12/+4
| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The value returned by an spi driver's remove function is mostly ignored. (Only an error message is printed if the value is non-zero that the error is ignored.) So change the prototype of the remove function to return no value. This way driver authors are not tempted to assume that passing an error to the upper layer is a good idea. All drivers are adapted accordingly. There is no intended change of behaviour, all callbacks were prepared to return 0 before.

| * | mtd: core: Fix a conflict between MTD and NVMEM on wp-gpios propertyChristophe Kerello2022-02-211-0/+2
| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Wp-gpios property can be used on NVMEM nodes and the same property can be also used on MTD NAND nodes. In case of the wp-gpios property is defined at NAND level node, the GPIO management is done at NAND driver level. Write protect is disabled when the driver is probed or resumed and is enabled when the driver is released or suspended. When no partitions are defined in the NAND DT node, then the NAND DT node will be passed to NVMEM framework. If wp-gpios property is defined in this node, the GPIO resource is taken twice and the NAND controller driver fails to probe. A new Boolean flag named ignore_wp has been added in nvmem_config. In case ignore_wp is set, it means that the GPIO is handled by the provider. Lets set this flag in MTD layer to avoid the conflict on wp_gpios property.

* | mtd: rawnand: brcmnand: Fixed incorrect sub-page ECC statusdavid regan2022-01-311-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The brcmnand driver contains a bug in which if a page (example 2k byte) is read from the parallel/ONFI NAND and within that page a subpage (512 byte) has correctable errors which is followed by a subpage with uncorrectable errors, the page read will return the wrong status of correctable (as opposed to the actual status of uncorrectable.) The bug is in function brcmnand_read_by_pio where there is a check for uncorrectable bits which will be preempted if a previous status for correctable bits is detected. The fix is to stop checking for bad bits only if we already have a bad bits status.

This caused the board to reset. Playing about with the probe() function shows that the problem lies in the core clock being switched off before the nandc_unalloc() routine has completed. If we look at how qcom_nandc_remove() tears down allocated resources we see the expected order is qcom_nandc_unalloc(nandc); clk_disable_unprepare(nandc->aon_clk); clk_disable_unprepare(nandc->core_clk); dma_unmap_resource(&pdev->dev, nandc->base_dma, resource_size(res), DMA_BIDIRECTIONAL, 0); Tweaking probe() to both bring up and tear-down in that order removes the reset if we end up deferring elsewhere.

| * | dmaengine: qcom-adm: stop abusing slave_id configArnd Bergmann2021-12-171-2/+12
| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The slave_id was previously used to pick one DMA slave instead of another, but this is now done through the DMA descriptors in device tree. For the qcom_adm driver, the configuration is documented in the DT binding to contain a tuple of device identifier and a "crci" field, but the implementation ends up using only a single cell for identifying the slave, with the crci getting passed in nonstandard properties of the device, and passed through the dma driver using the old slave_id field. Part of the problem apparently is that the nand driver ends up using only a single DMA request ID, but requires distinct values for "crci" depending on the type of transfer. Change both the dmaengine driver and the two slave drivers to allow the documented binding to work in addition to the ad-hoc passing of crci values. In order to no longer abuse the slave_id field, pass the data using the "peripheral_config" mechanism instead.

Otherwise this rate change can lead to an unresponsive GPMI core which results in DMA timeouts and failed driver probe: [ 4.072318] gpmi-nand 112000.gpmi-nand: DMA timeout, last DMA ... [ 4.370355] gpmi-nand 112000.gpmi-nand: Chip: 0, Error -110 ...

Other than stated in i.MX 6 erratum ERR007117, it should be sufficient to gate only gpmi_io because all other bch/nand clocks are derived from different clock roots. The i.MX6 reference manuals state that changing clock muxers can cause glitches but are silent about changing dividers. But tests showed that these glitches can definitely happen on i.MX6ULL. For i.MX7D/8MM in turn, the manual guarantees that no glitches can happen when changing dividers.

Indeed, the old JZ4740 NAND driver (removed in 5.4) did use the 'OOB first' flag that existed back then. Use the newly created nand_read_page_hwecc_oob_first() to address this issue. This issue was not found when the new ingenic-nand driver was developed, most likely because the Device Tree used had the nand-ecc-mode set to "hw_oob_first", which seems to not be supported anymore.
