[PATCH 01/15] ARM: shmobile: r8a7790: switch console back to scif0

[Simon Horman]

From: Ulrich Hecht <ulrich.hecht+renesas@gmail.com>

The boot loader uses scif0, and so must we if we want earlycon to work.

Partially reverts 7c0558941 ("ARM: shmobile: r8a7790: switch from scif
to scifa").

[PATCH 02/15] ARM: shmobile: bockw dts: define sdhi0 pins with pull-ups

[Simon Horman]

From: Ulrich Hecht <ulrich.hecht+renesas@gmail.com>

Ensures that the pull-ups for pins SD0_CD and SD0_WP are enabled.

This is one of two features from the DT reference platform that are
still missing in MP.

[PATCH 11/15] ARM: shmobile: silk: Move SPI FLASH partitions to subnode

[Simon Horman]

From: Geert Uytterhoeven <geert+renesas@glider.be>

As of commits 5cfdedb7b9a0fe38 ("mtd: ofpart: move ofpart partitions to a
dedicated dt node") and fe2585e9c29a650a ("doc: dt: mtd: support partitions
in a special 'partitions' subnode"), having partitions as direct subnodes
of an mtd device is discouraged. Hence move the SPI FLASH partitions to a
"partitions" subnode.

Based on similar work for the koelsch board by Geert Uytterhoeven.

[PATCH 12/15] ARM: shmobile: alt: Correct scif2 pfc

[Simon Horman]

22b160713cb6 ("ARM: shmobile: alt: Add pfc pins to DT") introduced pfc pins
to the alt device tree but did not reference them. This patch fixes scif2
pfc by adding references to the scif2 pins.

[PATCH 13/15] ARM: shmobile: alt: Correct ether pfc

[Simon Horman]

22b160713cb6 ("ARM: shmobile: alt: Add pfc pins to DT") introduced pfc pins
to the alt device tree but did not reference them. This patch fixes ether
pfc by:

* Referencing ether pins
* Adding and referencing phy1 pins
* Removing ether b pins. These are not used in the configuration
  of the alt board used for testing and empirically their presence
  prevents ethernet from functioning correctly in that environment.

[PATCH 14/15] ARM: shmobile: r8a7740 dtsi: Add L2 cache-controller node

[Simon Horman]

From: Geert Uytterhoeven <geert+renesas@glider.be>

Add the missing L2 cache-controller node, and link the CPU node to it.
This will allow migration to the generic l2c OF initialization.

The L2 cache is an ARM L2C-310 (r3p1-150rel0), of size 256 KiB (32 KiB x
8 ways).
