Tudor Ambarus 5f340402bb mtd: spi-nor: Remove debugfs entries that duplicate sysfs entries
SPI NOR sysfs defines partname and jedec_id device attributes, which
duplicate the information from debugfs. Since the sysfs directory
structure and the attributes in each directory define an ABI between the
kernel and user space, thus it can never be removed, remove the debugfs
entries so that we don't duplicate the information.

Pratyush Yadav 9de3cb1cc9 mtd: spi-nor: micron-st: write 2 bytes when disabling Octal DTR mode
The Octal DTR configuration is stored in the CFR0V register. This
register is 1 byte wide. But 1 byte long transactions are not allowed in
8D-8D-8D mode. The next byte address contains the CFR1V register, which
contains the number of dummy cycles. This is very fortunate since the
enable path changes the value of this register. Reset the value to its
default when disabling Octal DTR mode. This way, both changes to the
flash state made when enabling can be reverted in one single
transaction.

The Octal DTR configuration is stored in the CFR5V register. This
register is 1 byte wide. But 1 byte long transactions are not allowed in
8D-8D-8D mode. Since the next byte address does not contain any
register, it is safe to write any value to it. Write a 0 to it.

Pratyush Yadav 0d051a4982 mtd: spi-nor: core: use 2 data bytes for template ops
The template ops used in spi_nor_spimem_check_pp() and
spi_nor_spimem_check_readop() currently set the data phase to 1 byte
long. 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.

Roger Quadros 4695a3cf00 mtd: rawnand: omap2: fix force_8bit flag behaviour for DMA mode
