Input: atmel_mxt_ts - add support for reset line

2018-11-29T12:54:04+00:00

Provide support for controlling reset pin. If this is not driven
correctly the device will be held in reset and will not respond.

give up on gcc ilog2() constant optimizations

2018-09-12T07:21:45+00:00

gcc-7 has an "optimization" pass that completely screws up, and
generates the code expansion for the (impossible) case of calling
ilog2() with a zero constant, even when the code gcc compiles does not
actually have a zero constant.

And we try to generate a compile-time error for anybody doing ilog2() on
a constant where that doesn't make sense (be it zero or negative).  So
now gcc7 will fail the build due to our sanity checking, because it
created that constant-zero case that didn't actually exist in the source
code.

There's a whole long discussion on the kernel mailing about how to work
around this gcc bug.  The gcc people themselevs have discussed their
"feature" in

   https://gcc.gnu.org/bugzilla/show_bug.cgi?id=72785

but it's all water under the bridge, because while it looked at one
point like it would be solved by the time gcc7 was released, that was
not to be.

So now we have to deal with this compiler braindamage.

And the only simple approach seems to be to just delete the code that
tries to warn about bad uses of ilog2().

So now "ilog2()" will just return 0 not just for the value 1, but for
any non-positive value too.

It's not like I can recall anybody having ever actually tried to use
this function on any invalid value, but maybe the sanity check just
meant that such code never made it out in public.

crypto: Add a flag to identify crypto instances

2017-12-21T01:05:35+00:00

The upcomming crypto user configuration api needs to identify
crypto instances. This patch adds a flag that is set if the
algorithm is an instance that is build from templates.
