From 945e48a39c957924bc84d1a6c137da039e13855b Mon Sep 17 00:00:00 2001 From: Wadim Egorov Date: Wed, 21 May 2025 07:33:39 +0200 Subject: [PATCH 01/33] arm64: dts: ti: k3-am642-phyboard-electra: Fix PRU-ICSSG Ethernet ports For the ICSSG PHYs to operate correctly, a 25 MHz reference clock must be supplied on CLKOUT0. Previously, our bootloader configured this clock, which is why the PRU Ethernet ports appeared to work, but the change never made it into the device tree. Add clock properties to make EXT_REFCLK1.CLKOUT0 output a 25MHz clock.

This is HW PoR configuration, the slew rate requirements without ST enabled are pretty tough for these devices. We've noticed spurious GPIO interrupts even with noise-free edges but not meeting slew rate requirements (3.3E+6 V/s for 3.3v LVCMOS). It's not obvious why one might want to disable the PoR-enabled ST on any pin. Just enable it by default. As it's not possible to provide OR-able macros to disable the ST, shall anyone require it, provide a set of new macros with _NOST suffix.

It features up to four Cortex-A53 cores (1.4GHz), two Cortex-R5F cores, and a C7x DSP with 2 TOPS MMA. Key interfaces include multi-channel McASP audio, TSN-capable Gigabit Ethernet, and a range of peripherals (UART, SPI, I2C, CAN, USB, eMMC/SD, OSPI, CSI). It supports LPDDR4/DDR4, secure boot with hardware security, and low-power modes with CAN/GPIO/UART wakeup. This SoC is of part K3 AM62x family, which includes the AM62A and AM62P variants. A key distinction is that the AM62D does not include multimedia components such as the video encoder/decoder, MJPEG encoder, Vision Processing Accelerator (VPAC) for image signal processing, or the display subsystem. Additionally, the AM62D has a different pin configuration compared to the AM62A, which impacts embedded software development. This adds dt bindings for TI's AM62D2 family of devices.

To reduce duplication, AM62D support reuses the AM62A dtsi and the necessary overrides will be handled in SOC specific dtsi file and a board specific dts. Add basic support for AM62D2-EVM.
