2020-01-20arm: dts: k3-am654-base-board: enable USB1Vignesh Raghavendra
Add pinmux for USB1 and enable it as a peripheral port in U-Boot specific dtsi since U-Boot does not support OTG. Disable USB0 as its not available on the baseboard. Signed-off-by: Vignesh Raghavendra <vigneshr@ti.com> Signed-off-by: Lokesh Vutla <lokeshvutla@ti.com>
2019-10-11arm: dts: k3-am65-mcu: Add MCU domain R5F DT nodesSuman Anna
The AM65x SoCs has a single dual-core Arm Cortex-R5F processor subsystem/cluster (MCU_R5FSS0) within the MCU domain. This cluster can be configured at boot time to be either run in a LockStep mode or in an Asymmetric Multi Processing (AMP) fashion in Split-mode. This subsystem has 64 KB each Tightly-Coupled Memory (TCM) internal memories for each core split between two banks - ATCM and BTCM (further interleaved into two banks). There are some IP integration differences from standard Arm R5 clusters such as the absence of an ACP port, presence of an additional TI-specific Region Address Translater (RAT) module for translating 32-bit CPU addresses into larger system bus addresses etc. Add the DT node for the MCU domain R5F cluster/subsystem, the two R5 cores are added as child nodes to the main cluster/subsystem node. The cluster is configured to run in Split-mode by default, with the ATCMs enabled to allow the R5 cores to execute code from DDR with boot-strapping code from ATCM. The inter-processor communication between the main A72 cores and these processors is achieved through shared memory and Mailboxes.

2019-07-17arm64: dts: k3-am654-base-board: Add I2C GPIO expander @ 0x38Andreas Dannenberg
The AM654 base board has a TCA9554/PCA9554-type GPIO expander on the wkup_i2c0 bus at address 0x38 that is used to detect the presence of daughter cards. Add a respective DTS description of this expander to enable its use. Signed-off-by: Andreas Dannenberg <dannenberg@ti.com> Reviewed-by: Lokesh Vutla <lokeshvutla@ti.com>
2019-07-17arm: dts: k3-am654-base-board: Enable wkup_i2c0 across all boot stagesAndreas Dannenberg
To enable the use of an EEPROM-based board detection scheme we need to be able to access the I2C bus associated with the EEPROMs across all 3 stages of U-Boot: R5 SPL, A53 SPL, and A53 U-Boot (proper). So go ahead and add/update the wkup_i2c0 peripheral module DTS definitions and its associated pinmux node accordingly.

2019-07-17arm64: dts: k3: Sync sdhci0 node from kernel and change driver nameFaiz Abbas
Sync the sdhci0 node from kernel. This changes the compatible that is required to be there in the driver. Change the same for the SD card node which is not yet supported in kernel. This also syncs the main_pmx0 node as a side effect. Also change the name of the driver to match the compatible in kernel.
