[PATCH] ezchip: nps_enet: check if napi has been completed

trapped in interrupt hanlder chain as we had never been able to disabale ethernet interrupts again. So this patch makes nps_enet_poll() func verify return value of napi_complete_done() and enable interrupts only in case all scheduled work has been completed. Signed-off-by: Vlad Zakharov <v

update timer frequencies

some minor changes to timekeeping framework to resolve this issue (special flag that allows such changes or something like this?). Thanks. -- Best regards, Vlad Zakharov <vzak...@synopsys.com>

[PATCH 3/3] arc: get rate from clk driver instead of reading device tree

n't work as rate may change during the time or even "clock-frequency" property may not be presented at all. So this commit replaces reading device tree with getting rate from clock driver. This approach is much more flexible and will work for both fixed and mutable clocks. Sign

This patch series replaces reading device tree with getting CPU clock frequency via clock driver in show_cpuinfo function. In order to achieve this we also add cpu nodes to device tree which describes SMP system and add "clocks" properties to all ARC cpu nodes. Vlad Zakharov (3):
