[PATCH 0/2] TQMa91xx support

[PATCH 0/2] TQMa91xx support

[Alexander Stein]

Hi,

this series supports i.MX91 based module series TQMa91xx. It is available
in a socketable variant (CA [1]) and as an LGA variant (LA [2]). Both
are covered by the same device tree file.
The hardware is identical to their TQMa93xx counterparts, just a different SoC.

This series depends on the i.MX91 SoC support [3].

Best regards
Alexander Stein

[PATCH 1/2] dt-bindings: arm: fsl: add TQMa91xxLA SOM

[Alexander Stein]

TQMa91xxLA is a SOM variant in the TQ-Systems GmbH TQMa91xx series using
NXP i.MX91 CPU on an LGA type board.
MBa91xxCA is a starterkit base board for TQMa91xxLA on an adapter board.

[PATCH 2/2] arm64: dts: freescale: add initial device tree for TQMa91xxCA/MBa91xxCA

[Alexander Stein]

This adds support for TQMa91xxCA module attached to MBa91xxCA board.
TQMa91xx is a SOM using i.MX91 SOC. The SOM features PMIC, RAM, e-MMC and
some optional peripherals like SPI-NOR, RTC, EEPROM, gyroscope and
secure element.

Your commit is for TQMa91xxCA and TQMa91xxLA.
However, the commit message only specifies TQMa91xxLA.
The TQMa91xxCA is missing from the commit subject and message.

You are right. There is no direct user in DT, but their connection is fixed
to JTAG. I'll hook it up to gpio3, as the GPIOs on these pads belong
to this controller.

Device tree spec name recommendation only mentions gyrometer, but this is a
gyroscope, so I will go with the latter one.
