[PATCH v2 0/2] Add STM32MP157 discovery boards support

[Alexandre Torgue]

This patch series add support of two new discovery boards based on
STM32MP157 MPU: stm32mp157a-dk1 and stm32mp157c-dk2.

stm32mp157a-dk1 board embeds a STM32MP157a SOC with AC package (TFBGA361,
148 ios) and 512MB of DDR3. Several connections are available on this boards:
4*USB2.0, 1*USB2.0 typeC, SDcard, RJ45, HDMI, Arduino connector, ...

stm32mp157c-dk2 board complements stm32mp157a-dk1 board with a display panel
(otm8009a) and a Murata Wifi/BT combo. It embeds a STM32MP157c SOC with AC
package.

Those patches enable basic support for a kernel boot.

Alex

[PATCH 2/2] ARM: dts: stm32: add initial support of stm32mp157c-dk2 board

[Alexandre Torgue]

Add support of stm32mp157c discovery2 board (part number: STM32MP157C-DK2).
This board is a "super-set" of stm32mp157a-dk1. It embeds a STM32MP157c SOC
with AC package (TFBGA361, 148 ios) and 512MB of DDR3. Same connections
than stm32mp157a-dk1 board are available. Display panel (otm8009a) and
Murata wifi/BT combo is added.

This patch adds basic support for a kernel boot and enable otm8009a display
panel.

Typo in title, it's a v1 not a v2.
