net/wan/fsl_ucc_hdlc: add hdlc-bus support

2017-05-18T14:28:39+00:00

This adds support for hdlc-bus mode to the fsl_ucc_hdlc driver. This can
be enabled with the "fsl,hdlc-bus" property in the DTS node of the
corresponding ucc.

This aligns the configuration of the UPSMR and GUMR registers to what is
done in our ucc_hdlc driver (that only support hdlc-bus mode) and with
the QuickEngine's documentation for hdlc-bus mode.

GUMR/SYNL is set to AUTO for the busmode as in this case the CD signal
is ignored. The brkpt_support is enabled to set the HBM1 bit in the
CMXUCR register to configure an open-drain connected HDLC bus.

fsl/qe: add bit description for SYNL register for GUMR

2017-05-18T14:28:39+00:00

Merge tag 'powerpc-4.12-2' of git://git.kernel.org/pub/scm/linux/kernel/git/powerpc/linux

2017-05-12T17:04:09+00:00

Pull more powerpc updates from Michael Ellerman:
 "The change to the Linux page table geometry was delayed for more
  testing with 16G pages, and there's the new CPU features stuff which
  just needed one more polish before going in. Plus a few changes from
  Scott which came in a bit late. And then various fixes, mostly minor.

  Summary highlights:

   - rework the Linux page table geometry to lower memory usage on
     64-bit Book3S (IBM chips) using the Hash MMU.

   - support for a new device tree binding for discovering CPU features
     on future firmwares.

   - Freescale updates from Scott:
      "Includes a fix for a powerpc/next mm regression on 64e, a fix for
       a kernel hang on 64e when using a debugger inside a relocated
       kernel, a qman fix, and misc qe improvements."

  Thanks to: Christophe Leroy, Gavin Shan, Horia Geantă, LiuHailong,
  Nicholas Piggin, Roy Pledge, Scott Wood, Valentin Longchamp"

Since commit 5093bb965a163 ("powerpc/QE: switch to the cpm_muram
implementation"), muram area is not part of immrbar mapping anymore
so immrbar_virt_to_phys() is not usable anymore.

The hardware descriptors have big endian (BE) format.
Provide proper endianness handling for the remaining
descriptor fields, to ensure they are correctly
accessed by non-BE CPUs too.
