BeagleBoard.org BeagleBone AI rev A1 does not include a board identifier I2C EEPROM due to a design oversight. These boards have been put into production and are generally available now.

The board identifier information, however, has been included in the second eMMC linear boot partition (/dev/mmcblk1boot1).

This patch works by: * First, looking for a board identifier I2C EEPROM and if not found, * Then seeing if the boot mode matches BeagleBone AI with eMMC in the boot chain to make sure we don't enable eMMC pinmuxes on boards that don't support it, and * Finally, initializes the eMMC pins and reading the header.

BeagleBoard.org BeagleBone AI is an open source hardware single board computer based on the Texas Instruments AM5729 SoC featuring dual-core 1.5GHz Arm Cortex-A15 processor, dual-core C66 digital signal processor (DSP), quad-core embedded vision engine (EVE), Arm Cortex-M4 processors, dual programmable realtime unit industrial control subsystems and more. The board features 1GB DDR3L, USB3.0 Type-C, USB HS Type-A, microHDMI, 16GB eMMC flash, 1G Ethernet, 802.11ac 2/5GHz, Bluetooth, and BeagleBone expansion headers.

For more information, refer to: https://beaglebone.ai

The corresponding patch against the mainline linux kernel can be found at: https://patchwork.kernel.org/patch/11254903/

This patch introduces the BeagleBone AI device tree.

Note that the device use the "ti,tpd12s016" component which is software compatible with "ti,tpd12s015". Thus we only use the latter driver.

Due to small modifications in ocp, a tag was added to dra7.dtsi in the ocp component.
