| * | 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.

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.

Right after the OOB data was read, it called nand_read_page_op() to reset the read cursor to the beginning of the page. This caused the first page to be read twice: in that call, and later in the loop. Address that issue by changing the call to nand_read_page_op() to nand_change_read_column_op(), which will only reset the read cursor.

Flash parameters and settings that are SFDP discoverable should not be duplicated via flash_info flags at flash declaration. - Remove debugfs entries that duplicate sysfs entries. SPI NOR manufacturer drivers changes: - Use late_init() hook in various drivers to make it clear that those flash parameters are either not declared in the JESD216 SFDP standard, or the SFDP tables which define those flash parameters are not defined by the flash. - Fix mtd size for s3an flashes. - Write 2 bytes when disabling Octal DTR mode: 1 byte long transactions are not allowed in 8D-8D-8D mode.

This is problematic for 8D-8D-8D protocol where odd length data phase is invalid since one cycle transfers 2 bytes and odd number of bytes would mean half a cycle is left over. This could result in a controller rejecting the op as "not supported" even though it actually supports the protocol. Change the data length to 2 bytes in these templates. One might argue that this should only be done for 8D-8D-8D operations but when talking about these templates, there is no functional difference between one and two bytes, even in STR modes.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | spi_nor_setup() configures the SPI NOR memory. Setting the addr width is too a configuration, hence we can move the spi_nor_set_addr_width() in spi_nor_setup().

Keep the old way of initializing the flash, until all the flashes are converted to use either PARSE_SFDP or SPI_NOR_SKIP_SFDP. Flashes that declare PARSE_SFDP do not have a roll-back mechanism because if spi_nor_parse_sfdp() returns an error it means that either BFPT is not supported, thus SFDP is not supported and the user didn't correctly declared the flash_info entry, or some memalloc failed. Either way we should return an error. The rest of the SFDP tables are optional, if one of the optional SFDP tables fails, we just continue. We would like to get rid of the default_init() hook, so the spi_nor_manufacturer_init_params() is not called in the new sequnce of flash initialization. Split spi_nor_info_init_params() in spi_nor_init_default_params() and spi_nor_no_sfdp_init_params(). spi_nor_init_default_params() is called for all the flashes regardless if they support SFDP or not. spi_nor_no_sfdp_init_params() is called just for the flashes that do not define SFDP and initializes parameters and setting solely based on flash_info data.

Introduce a dedicated function for setting the fixup_flags and emphasise when those flash_info flags should be set: when the SNOR_F_4B_OPCODES/SNOR_F_IO_MODE_EN_VOLATILE setttings can not be discovered by SFDP for this particular flash because the SFDP table that indicates this support is not defined in the flash. In case the table for his support is defined but has wrong values, one should instead use a post_sfdp() hook to set the SNOR_F equivalent flag. No functional change intended in this patch.

The rest of the flags were already set after the spi_nor_init_params().
