This enhances the DTs for the IOT2050, primarily by added support for
upcoming Production Generation 2 (PG2) and by ordering the MMC devices
consistently across variants.

Changes in 3:
 - move mmc alias back into board DTs
 - add patch to enable R5F cores for rproc

Changes in v2:
 - move mmc alias to SoC level
 - split up into PG2 preparation and addition patch
 - add link to product homepage

This ensures that the SD card will remain mmc0 across Basic and Advanced
devices, also avoiding surprises for users coming from the downstream
kernels.

The IOT2050 devices described so far are using SR1.0 silicon, thus do
not have the additional PRUs of the ICSSG of the SR2.0. Disable them.

From: Jan Kiszka <jan.kiszka@siemens.com>

Analogously to the am654-base-board, configure the mailboxes for the the
two R5F cores, add them and the already existing memory carve-outs to
the related MCU nodes. Allows to load applications under Linux onto the
cores, e.g. the RTI watchdog firmware.

* [PATCH v3 4/5] arm64: dts: ti: iot2050: Prepare for adding 2nd-generation boards

From: Jan Kiszka <jan.kiszka@siemens.com>

The current IOT2050 devices are Product Generation 1 (PG1), using SR1.0
AM65x silicon. Upcoming PG2 devices will use SR2.x SoCs and will
therefore need separate device trees. Prepare for that by factoring out
common bits that will be shared across both generations.

At this chance, drop a link to the product homepage to in the top-level
dts files.

* [PATCH v3 4/5] arm64: dts: ti: iot2050: Prepare for adding 2nd-generation boards
@ 2021-09-09 19:41   ` Jan Kiszka
  0 siblings, 0 replies; 24+ messages in thread
From: Jan Kiszka @ 2021-09-09 19:41 UTC (permalink / raw)
  To: Nishanth Menon, Tero Kristo, Rob Herring
  Cc: linux-arm-kernel, linux-kernel, devicetree, Bao Cheng Su, Chao Zeng

From: Jan Kiszka <jan.kiszka@siemens.com>

The current IOT2050 devices are Product Generation 1 (PG1), using SR1.0
AM65x silicon. Upcoming PG2 devices will use SR2.x SoCs and will
therefore need separate device trees. Prepare for that by factoring out
common bits that will be shared across both generations.

At this chance, drop a link to the product homepage to in the top-level
dts files.

* [PATCH v3 5/5] arm64: dts: ti: iot2050: Add support for product generation 2 boards

From: Jan Kiszka <jan.kiszka@siemens.com>

This adds the devices trees for IOT2050 Product Generation 2 (PG2)
boards. We have Basic and an Advanced variants again, differing in
number of cores, RAM size, availability of eMMC and further details.
The major difference to PG1 is the used silicon revision (SR2.x on
PG2).
