2018-07-19mtd: rawnand: tegra: check bounds of die_nr properlyStefan Agner
The Tegra driver currently only support a single chip select, hence check boundaries accordingly. This fixes a off by one issue catched with Smatch: drivers/mtd/nand/raw/tegra_nand.c:476 tegra_nand_select_chip() warn: array off by one? 'nand->cs[die_nr]' Also warn in case the stack asks for a chip select we currently do not support.

2018-07-19mtd: rawnand: add default values for dynamic timingsMiquel Raynal
Some timings like tBERS (block erase time), tCCs (change column setup time), tPROG (page program time) and tR (page read time) are derived from the ONFI parameter page. They are set in the SDR interface only if the chip is ONFI compliant. It makes these timings unreliable and prevent the driver to use one of these four values with a non-ONFI chip. Fix this situation by taking the highest possible value (or a default one) value for each missing timing (stored as unsigned 16-bit entries in the parameter page). This makes tBERS and tPROG being ~65ms while typical values are at most a few milliseconds. As these are timeouts, it is not impacting at all the performances in nominal use. tR maximum time and tCCS minimum time (delay to wait after a change column) are set, according to the ONFI specification, to default 'slow' values; respectively 200us and 500ns.

2018-07-18mtdchar: fix overflows in adjustment of `count`Jann Horn
The first checks in mtdchar_read() and mtdchar_write() attempt to limit `count` such that `*ppos + count <= mtd->size`. However, they ignore the possibility of `*ppos > mtd->size`, allowing the calculation of `count` to wrap around. `mtdchar_lseek()` prevents seeking beyond mtd->size, but the pread/pwrite syscalls bypass this. I haven't found any codepath on which this actually causes dangerous behavior, but it seems like a sensible change anyway.

2018-07-18mtd: Fallback to ->_read/write() when ->_read/write_oob() is missingMiquel Raynal
Some MTD sublayers/drivers are implementing ->_read/write() and not ->_read/write_oob(). While for NAND devices both are usually valid, for NOR devices, using the _oob variant has no real meaning. But, as the MTD layer is supposed to hide as much as possible the flash complexity to the user, there is no reason to error out while it is just a matter of rewritting things internally. Add a fallback on mtd->_read() (resp. mtd->_write()) when the user calls mtd_read_oob() (resp. mtd_write_oob()) while mtd->_read_oob() (resp. mtd->_write_oob) is not implemented. There is already a fallback on the _oob variant if the former is used. Signed-off-by: Miquel Raynal <miquel.raynal@bootlin.com> Signed-off-by: Boris Brezillon <boris.brezillon@bootlin.com>

This patch restores the suspend and resume hooks that the old driver used to have. Apart from stopping and starting the clocks, the resume callback also nullifies the selected_chip pointer, so the next command that is issued will re-select the chip and thereby restore the timing registers. Factor out some code from marvell_nfc_init() into a new function marvell_nfc_reset() and also call it at resume time to reset some registers that don't retain their contents during low-power mode. Without this patch, a PXA3xx based system would cough up an error similar to the one below after resume.
