2017-05-31net: dsa: remove dev arg of dsa_register_switchVivien Didelot6-6/+6
The current dsa_register_switch function takes a useless struct device pointer argument, which always equals ds->dev. Drivers either call it with ds->dev, or with the same device pointer passed to dsa_switch_alloc, which ends up being assigned to ds->dev. This patch removes the second argument of the dsa_register_switch and _dsa_register_switch functions. Signed-off-by: Vivien Didelot <vivien.didelot@savoirfairelinux.com> Signed-off-by: David S.

2017-05-30nfp: support long reads and writes with the cpp helpersJakub Kicinski2-18/+72
nfp_cpp_{read,write}() helpers perform device memory mapping (setting the PCIe -> NOC translation BARs) and accessing it. They, however, currently implicitly expect that the length of entire operation will fit in one BAR translation window. There is a number of 16MB windows available, and we don't really need to access such large areas today. If the user, however, manages to trick the driver into making a big mapping (e.g. by providing a huge fake FW file), the driver will print a warning saying "No suitable BAR found for request" and a stack trace - which most users find concerning. To be future-proof and not scare users with warnings, make the nfp_cpp_{read,write}() helpers do accesses chunk by chunk if the area size is large. Set the notion of "large" to 2MB, which is the size of the smallest BAR window. Signed-off-by: Jakub Kicinski <jakub.kicinski@netronome.com> Signed-off-by: David S. Miller <davem@davemloft.net>
