      regulator: tps6586x: Add and use correct voltage table · 844a4f0d
      Stefan Agner authored 
      

Depending on the regulator version, the voltage table might be
different. Use version specific regulator tables in order to select
correct voltage table. For the following regulator versions different
voltage tables are now used:

  * TPS658623: Use correct voltage table for SM2
  * TPS658643: New voltage table for SM2

Both versions are in use on the Colibri T20 module. Make use of the
correct tables by requesting the correct SM2 voltage of 1.8V.

This change is not backward compatible since an old driver is not able
to correctly set that value. The value 1.8V is out of range for the old
driver and will refuse to probe the device. The regulator starts with
default settings and the driver shows appropriate error messages.

On Colibri T20, the old value used to work with TPS658623 since the
driver applied a wrong voltage table too. However, the TPS658643 used
on V1.2 devices uses yet another voltage table and those broke that
pseudo-compatibility. The regulator driver now has the correct voltage
table for both regulator versions and those the correct voltage can be
used in the device tree.

      ARM: shmobile: r8a7790.dtsi: ficx i2c[0-3] clock reference · 2450badf
      Ben Dooks authored 
      

The R8A7790's dtsi file i2c0, i2c1, i2c2, and i2c3 nodes have clock
references to the mstp3_clks clock node, however these clocks are in the
mstp9_clks node.

The error was introducted in 72197ca7 ("ARM: shmobile: r8a7790:
 Reference clocks") which is in Simon's current development tree.

This patch fixes the following error:

of_clk_src_onecell_get: invalid clock index 31
i2c-rcar e6508000.i2c: cannot get clock
i2c-rcar: probe of e6508000.i2c failed with error -2

      dt/bindings: remove device_type "network" references · 35129175
      Grant Likely authored 
      

device_type is deprecated and the kernel doesn't require it in most
cases. The only exceptions for flat tree users are the "gianfar",
"ucc_geth" and "ibm,emac" bindings, and arguably that requirement could
be relaxed for ucc_geth and ibm,emac (that is a task for separate
patches though).

This patch removes references to device_type="network" from the binding
documentation where possible and removes the properties from ARM and
microblaze dts files. This patch does not modify the powerpc .dts files
since there are a much larger number of them affected and I think the
ucc_geth, ibm,emac and gianfar users should be addressed before clearing
out the references to reduce the chance of breakage.
