Stephen Boyd 38ff87f77a sched_clock: Make ARM's sched_clock generic for all architectures
Nothing about the sched_clock implementation in the ARM port is
specific to the architecture. Generalize the code so that other
architectures can use it by selecting GENERIC_SCHED_CLOCK.

Arnd Bergmann 8024206dbf ARM: tegra: cleanup
This branch includes various cleanup of the core Tegra support.
 
 * Unification of the separate board-dt-tegra*.c files into a single
   tegra.c, now that everything is DT-driven and basically identical.
 * Use of_clk_get() in the Tegra clocksource driver so that clocks are
   described in DT rather than hard-coding clock names.
 * Some cleanup of the PMC-related code, with the aim that the PMC
   "driver" contains more of the code that touches PMC registers, rather
   than spreading PMC register accesses through other files.
 * Conversion of the "PMC" driver to acquire resources describe in device
   tree rather than hard-coding them.
 * Use of common code for the CPU sleep TLB invalidation.
 
 This branch is based on the previous fixes pull request.

Peter De Schrijver 6f88fb8af6 clocksource: tegra: move to of_clk_get
The new clockframework introduced DT IDs for each clock. To be able to remove
the device registrations, this driver needs to be updated to use the DT IDs.
Note that the actual removal of the clk_register_clkdev() calls will be done
in a later series.

Now that we have OF based init with CLKSRC_OF, convert smp_twd init
function to use it and covert all callers of
twd_local_timer_of_register.

Rob Herring 1d16cfb3ae clocksource: tegra20: use the device_node pointer passed to init
We've already matched the node, so use the node pointer passed in. The rtc
init was intermingled with the timer init, so split this out to a separate
init function.

Rob Herring effbfdd7ba clocksource: pass DT node pointer to init functions
In cases where we have multiple nodes of the same type, we may need the
node pointer to know which node was matched. Passing the node pointer
also keeps the init function from having to match the node a 2nd time.

Update bcm2835, vt8500, and tegra20 init functions for the new function
prototype. Further tegra20 clean-ups are in follow-up commit.
