Merge tag 'arm-dt-5.18' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc
Pull ARM devicetree updates from Arnd Bergmann:
"After a somewhat quiet 5.17 release, the size of the DT changes is a
bit larger again. There are nine new SoC that get added, all of them
related to existing platforms:
- Airoha (formerly Mediatek/EcoNet) EN7523 networking SoC and EVB
- Mediatek mt6582 tablet platform with the Prestigio PMT5008 3G
tablet
- Microchip Lan966 networking SoC and it evaluation board
- Qualcomm Snapdragon 625/632 midrange phone SoCs, with the LG Nexus
5X and Fairphone FP3 phones
- Renesas RZ/G2LC and RZ/V2L general-purpose embedded SoCs, along
with their evaluation boards
- Samsung Exynos 850 phone SoC and reference board
- Samsung Exynos7885 with the Samsung Galaxy A8 (2018) phone
- Tesla FSD (Fully Self-Driving), an automotive SoC loosely derived
from the Samsung Exynos family.
- TI K3/AM62 SoC and reference board
Support for additional functionality in existing dts files is added
all over the place: Samsung, Renesas, Mstar, wpcm450, OMAP, AT91,
Allwinner, i.MX, Tegra, Aspeed, Oxnas, Qualcomm, Mediatek, and
Broadcom.
Samsung has a rework for its pinctrl schema that is a bit tricky and
requires driver changes to be included here.
A few more platforms only have smaller cleanups and DT Schema fixes,
this includes SoCFPGA, ux500, ixp4xx, STi, Xilinx Zynq, LG, and Juno.
The new machines are really too many to list, but I'll do it anyway:
Allwinner:
- A20-Marsboard development board
Amlogic:
- Amediatek X96-AIR (Amlogic S905X3)
- CYX A95XF3-AIR (Amlogic S905X3)
- Haochuangy H96-Max (Amlogic S905X3)
- Amlogic AQ222 (Amlogic S4)
- OSMC Vero 4K+ (Amlogic S905D)
Arm Juno:
- Separate DT depending on SCMI firmware version
Aspeed:
- Quanta S6Q BMC (AST2600)
- ASRock ROMED8HM3 (AST2500)
Broadcom:
- Raspberry Pi Zero 2 W
Marvell MVEBU/Armada:
- Ctera C200 V1 NAS (kirkwood)
- Ctera C200 V2 NAS (armada-370)
Mstar:
- DongShanPiOne, a low-end embedded board
- Miyoo Mini handheld game console
NXP i.MX:
- Numerous i.MX8M Mini based boards in even more variations, but
none based on other SoCs this time:
Protonic PRT8MM, emCON-MX8M Mini, Toradex Verdin, and
Gateworks GW7903
Qualcomm:
- Google Herobrine R1 Chromebook platform (Snapdragon 7c Gen 3)
- SHIFT6mq phone (Snapdragon 845)
- Samsung Galaxy Book2 (Snapdragon 850)
- Snapdragon 8 Gen 1 Hardware Development Kit
TI OMAP:
- SanCloud BeagleBone Enhanced WiFi
Rockchip:
- Pine64 PineNote ereader tablet (rk356x)
- Bananapi-R2-Pro (rk356x)
STM32:
- emtrion emSBS-Argon embedded board (stm32mp157c)"
