[PATCH v6 0/4] Add samsung-matisselte and common matisse dtsi

[Stefan Hansson]

This series adds a common samsung-matisse dtsi and reworks
samsung-matisse-wifi to use it, and introduces samsung-matisselte. I
choose matisselte over matisse-lte as this is how most other devices
(klte, s3ve3g) do it and it is the codename that Samsung gave the
device. See individual commits for more information.

---
Changes since v1:

 - Rebased on latest linux-next
 - Added qcom,msm8226 compatible to matisselte inspired by recent Lumia
   830 patch. This is done as in v1, the patch was rejected because I
   included the msm8226 dtsi despite not marking matisselte as
   compatible with msm8226, and I was not sure how to resolve that. As
   such, I'm copying what was done in the Lumia 830 (microsoft-tesla)
   patch given that it was accepted.

Changes since v2:

 - Updated commit message for UART patch to explain why it was added.
 - Gave more flags to git to provide a hopefully more readable patch.

Changes since v3:

 - Collect tags.
 - Remove spurious copyright notice.
 - Miscellaneous fixes following review feedback.

Changes since v4:

 - Collect tags.
 - Enable SD card support on matisselte.

Changes since v5:

 - Rebased on latest linux-next.

[PATCH v6 1/4] ARM: dts: qcom: samsung-matisse-common: Add initial common device tree

[Stefan Hansson]

According to the dts from the kernel source code released by Samsung,
matissewifi and matisselte only have minor differences in hardware, so
use a shared dtsi to reduce duplicated code. Additionally, this should
make adding support for matisse3g easier should someone want to do that
at a later point.

As such, add a common device tree for all matisse devices by Samsung
based on the matissewifi dts. Support for matisselte will be introduced
in a later patch in this series and will use the common dtsi as well.

[PATCH v6 3/4] ARM: dts: qcom: Add support for Samsung Galaxy Tab 4 10.1 LTE (SM-T535)

[Stefan Hansson]

Add a device tree for the Samsung Galaxy Tab 4 10.1 (SM-T535) LTE tablet
based on the MSM8926 platform.

The common dtsi is also modified to describe the widest constraints,
which required modifications to the matisse-wifi dts.

This was not enabled in the matisse-wifi tree. Without this, it is not
possible to use the USB port for serial debugging via a "Carkit debug
cable".
