| * dmaengine: at_xdmac: fix software lockup at_xdmac_tx_status()Cyrille Pitchen2014-11-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | According to the Atmel eXtended DMA controller datasheet, requesting a DMA transfer flush for a channel is only revelant when this transfer is source peripheral synchronized. So we have to check this condition before requesting a channel flush by writing the channel bit into the Global channel SoftWare Flush (GSWF) register then waiting for flush to complete by monitoring the end of Flush Interrupt Status (FIS) bit in the Channel Interrupt Status (CIS) register. Indeed, for non source peripheral synchronized transfer, writing the channel bit into the GSWF register does nothing. Especially, the FIS bit is never set into the CIS register. The former code looped forever waiting for this bit to be set.

With the restructuring of the m25p80.c driver and the SPI NOR library framework, we omitted proper listing of the SPI device IDs. This means m25p80.c wouldn't auto-load (modprobe) properly when built as a module. For now, we duplicate the device IDs into both modules. - The OMAP / ELM modules were depending on an implicit link ordering. Use deferred probing so that the new link order (in 3.18-rc) can still allow for successful probing. - Fix suspend/resume support for LH28F640BF NOR flash" * tag 'for-linus-20141102' of git://git.infradead.org/linux-mtd: mtd: cfi_cmdset_0001.c: fix resume for LH28F640BF chips mtd: omap: fix mtd devices not showing up mtd: m25p80,spi-nor: Fix module aliases for m25p80 mtd: spi-nor: make spi_nor_scan() take a chip type name, not spi_device_id mtd: m25p80: get rid of spi_get_device_id

All units are reset...". As workaround we refresh the PCR value as done initially on chip setup. This behavior and the fix are confirmed by our tests done on 2 different Zaurus collie units with kernel 3.17.

The MODULE_DEVICE_TABLE() macro doesn't work with extern definitions, but its use was also removed at the same time. Now if m25p80 is built as a module it doesn't get the necessary aliases to be loaded automatically. A clean solution to this will involve defining the list of device IDs in spi-nor.h and removing struct spi_device_id from the spi-nor API, but this is quite a large change. As a quick fix suitable for stable, copy the device IDs back into m25p80.
