2016-11-19mtd: nand: tango: Cleanup raw_write and raw_readMarc Gonzalez1-8/+6
Drop raw_write return value (no longer used). Drop raw_read return value (for symmetry). Signed-off-by: Marc Gonzalez <[email protected]> Signed-off-by: Boris Brezillon <[email protected]>
2016-11-19mtd: nand: tango: Enable custom page accessorsMarc Gonzalez1-1/+6
Enable NAND_ECC_CUSTOM_PAGE_ACCESS in the tango NFC driver. Fixup the "raw" page accessors to send the proper NAND commands. Signed-off-by: Marc Gonzalez <[email protected]> Signed-off-by: Boris Brezillon <[email protected]>
2016-11-19mtd: nand: Support controllers with custom pageMarc Gonzalez2-3/+43
If your controller already sends the required NAND commands when reading or writing a page, then the framework is not supposed to send READ0 and SEQIN/PAGEPROG respectively. Signed-off-by: Marc Gonzalez <[email protected]> Signed-off-by: Boris Brezillon <[email protected]>

2016-11-19mtd: nand: denali: remove "Spectra:" prefix from printk stringsMasahiro Yamada1-6/+5
As far as I understood from the Kconfig menu deleted by commit be7f39c5ecf5 ("Staging: delete spectra driver"), the "Spectra" is specific to Intel Moorestown Platform. The Denali NAND controller IP is used for various SoCs such as Altera SOCFPGA, Socionext UniPhier, etc. The platform specific strings are not preferred in this driver.

2016-11-19mtd: nand: denali: remove detect_partition_feature()Masahiro Yamada2-38/+0
The denali->fwblks is set by detect_partition_feature(), but it is not referenced from anywhere. That means the struct member fwblks and the whole of detect_partition_feature() are unneeded. The comment block implies this function is only for Intel platforms. I found drivers/staging/spectra used to exist, but it was deleted by commit be7f39c5ecf5 ("Staging: delete spectra driver") 5 years ago. So, I guess nobody would need this function any more.

The struct member "idx" was used as an index for debug_array long ago, but the DEBUG_DENALI feature was removed by commit 7cfffac06ca0 ("nand/denali: use dev_xx debug function to replace nand_dbg_print and some printk").
