2020-09-11spi: spi-fsl-dspi: use XSPI mode instead of DMA for DPAA2 SoCsVladimir Oltean
The arch/arm64/boot/dts/freescale/fsl-ls208xa.dtsi device tree lacks DMA channels for DSPI, so naturally, the driver fails to probe: [ 2.945302] fsl-dspi 2100000.spi: rx dma channel not available [ 2.951134] fsl-dspi 2100000.spi: can't get dma channels In retrospect, this should have been obvious, because LS2080A, LS2085A LS2088A and LX2160A don't appear to have an eDMA module at all. Looking again at their datasheets, the CTARE register (which is specific to XSPI functionality) seems to be documented, so switch them to XSPI mode instead.

2020-09-11hwrng: imx-rngc - add quality to use it as kernel entropy poolMarco Felsch
The RNGB can generate 2^20 words (1 word == 4 byte) of 'random' data after the seed pool was initialized. The pool needs to be reseeded if more words are required. The reseeding is done automatically since commit 3acd9ea9331c ("hwrng: imx-rngc - use automatic seeding"). We can't retrieve the TRNG values directly so we need a other way to get the quality level. We know that the PRNG uses 20.000 entropy samples from the TRNG to generate 2^20 words (1MiB) and the quality level is defined as (in bits of entropy per 1024 bits of input). So the quality level can be calculated by: 20.000 * 1024 ------------- = ~ 19.5 2^20 Signed-off-by: Marco Felsch <m.felsch@pengutronix.de> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

2020-09-10hdlc_ppp: add range checks in ppp_cp_parse_cr()Dan Carpenter
There are a couple bugs here: 1) If opt[1] is zero then this results in a forever loop. If the value is less than 2 then it is invalid. 2) It assumes that "len" is more than sizeof(valid_accm) or 6 which can result in memory corruption. In the case of LCP_OPTION_ACCM, then we should check "opt[1]" instead of "len" because, if "opt[1]" is less than sizeof(valid_accm) then "nak_len" gets out of sync and it can lead to memory corruption in the next iterations through the loop. In case of LCP_OPTION_MAGIC, the only valid value for opt[1] is 6, but the code is trying to log invalid data so we should only discard the data when "len" is less than 6 because that leads to a read overflow.

2020-09-10net: phy: call phy_disable_interrupts() in phy_attach_direct() insteadYoshihiro Shimoda
Since the micrel phy driver calls phy_init_hw() as a workaround, the commit 9886a4dbd2aa ("net: phy: call phy_disable_interrupts() in phy_init_hw()") disables the interrupt unexpectedly. So, call phy_disable_interrupts() in phy_attach_direct() instead. Otherwise, the phy cannot link up after the ethernet cable was disconnected. Note that other drivers (like at803x.c) also calls phy_init_hw(). So, perhaps, the driver caused a similar issue too.

2020-09-10floppy: use bdev_check_media_changeChristoph Hellwig
Switch to use bdev_check_media_change instead of check_disk_change and call floppy_revalidate manually. Given that floppy_revalidate only deals with media change events, the extra call into ->revalidate_disk from bdev_disk_changed is not required either, so stop wiring up the method.
