2018-04-05T03:07:20+00:00

Pull char/misc updates from Greg KH:
 "Here is the big set of char/misc driver patches for 4.17-rc1.

  There are a lot of little things in here, nothing huge, but all
  important to the different hardware types involved:

   -  thunderbolt driver updates

   -  parport updates (people still care...)

   -  nvmem driver updates

   -  mei updates (as always)

   -  hwtracing driver updates

   -  hyperv driver updates

   -  extcon driver updates

   -  ... and a handful of even smaller driver subsystem and individual
      driver updates

  All of these have been in linux-next with no reported issues"

nvmem: disallow modular CONFIG_NVMEM

2018-04-04T15:47:50+00:00

The new of_get_nvmem_mac_address() helper function causes a link error
with CONFIG_NVMEM=m:

drivers/of/of_net.o: In function `of_get_nvmem_mac_address':
of_net.c:(.text+0x168): undefined reference to `of_nvmem_cell_get'
of_net.c:(.text+0x19c): undefined reference to `nvmem_cell_read'
of_net.c:(.text+0x1a8): undefined reference to `nvmem_cell_put'

I could not come up with a good solution for this, as the code is always
built-in. Using an #if IS_REACHABLE() check around it would solve the
link time issue but then stop it from working in that configuration.
Making of_nvmem_cell_get() an inline function could also solve that, but
seems a bit ugly since it's somewhat larger than most inline functions,
and it would just bring that problem into the callers.  Splitting the
function into a separate file might be an alternative.

This uses the big hammer by making CONFIG_NVMEM itself a 'bool' symbol,
which avoids the problem entirely but makes the vmlinux larger for anyone
that might use NVMEM support but doesn't need it built-in otherwise.

nvmem: sunxi-sid: fix H3 SID controller support

2018-03-14T18:28:15+00:00

It seems that doing some operation will make the value pre-read on H3
SID controller wrong again, so all operation should be performed by
register.

Change the SID reading to use register only.

nvmem: add i.MX7 support to snvs-lpgpr

2018-03-14T18:28:14+00:00

The i.MX7 family has similar SNVS hardware so make the snvs-lpgpr
support it along with the i.MX6 family. The register interface is the
same except for the number and offset of the general purpose registers.

There's "dev" variable for this already. Use it.

Simplify code a bit by using of_device_get_match_data() instead of
of_match_device().
