stm32mp: stpmic1: remove the debug unit request by debugger

Depending on backup register value, U-Boot SPL maintains the debug unit
powered-on for debugging purpose; only BUCK1 is required for powering
the debug unit, so revert the setting for all the other power lanes,
except BUCK3 that has to be always on.

,openocd for example, to update the STM32MP15 backup register when it is
required to debug SPL after reset. After deeper analysis this behavior
will be never supported in tools so the associated code, will be never

The AM62 SoC family is the follow on AM335x built on K3 Multicore SoC
architecture platform, providing ultra-low-power modes, dual display,
multi-sensor edge compute, security and other BOM-saving integration.
The AM62 SoC targets broad market to enable applications such as
Industrial HMI, PLC/CNC/Robot control, Medical Equipment, Building
Automation, Appliances and more.

Some highlights of this SoC are:

* Quad-Cortex-A53s (running up to 1.4GHz) in a single cluster.
  Pin-to-pin compatible options for single and quad core are available.
* Cortex-M4F for general-purpose or safety usage.
* Dual display support, providing 24-bit RBG parallel interface and
  OLDI/LVDS-4 Lane x2, up to 200MHz pixel clock support for 2K display
  resolution.
* Selectable GPUsupport, up to 8GFLOPS, providing better user experience
  in 3D graphic display case and Android.
* PRU(Programmable Realtime Unit) support for customized programmable
  interfaces/IOs.
* Integrated Giga-bit Ethernet switch supporting up to a total of two
  external ports (TSN capable).
* 9xUARTs, 5xSPI, 6xI2C, 2xUSB2, 3xCAN-FD, 3x eMMC and SD, GPMC for
  NAND/FPGA connection, OSPI memory controller, 3xMcASP for audio,
  1x CSI-RX-4L for Camera, eCAP/eQEP, ePWM, among other peripherals.
* Dedicated Centralized System Controller for Security, Power, and
  Resource Management.
* Multiple low power modes support, ex: Deep sleep,Standby, MCU-only,
  enabling battery powered system design.

AM625 is the first device of the family. Add DT bindings for the same.

2 years agomisc: Add support for nvmem cells
Sean Anderson [Thu, 5 May 2022 17:11:39 +0000 (13:11 -0400)]
misc: Add support for nvmem cells

This adds support for "nvmem cells" as seen in Linux. The nvmem device
class in Linux is used for various assorted ROMs and EEPROMs. In this
sense, it is similar to UCLASS_MISC, but also includes
UCLASS_I2C_EEPROM, UCLASS_RTC, and UCLASS_MTD. New drivers corresponding
to a Linux-style nvmem device should be implemented as one of the
previously-mentioned uclasses. The nvmem API acts as a compatibility
layer to adapt the (slightly different) APIs of these uclasses. It also
handles the lookup of nvmem cells.

While nvmem devices can be accessed directly, they are most often used
by reading/writing contiguous values called "cells". Cells typically
hold information like calibration, versions, or configuration (such as
mac addresses).

nvmem devices can specify "cells" in their device tree:

qfprom: eeprom@700000 {
#address-cells = <1>;
#size-cells = <1>;
reg = <0x00700000 0x100000>;

/* ... */

tsens_calibration: calib@404 {
reg = <0x404 0x10>;
};
};

which can then be referenced like:

tsens {
/* ... */
nvmem-cells = <&tsens_calibration>;
nvmem-cell-names = "calibration";
};

The tsens driver could then read the calibration value like:

struct nvmem_cell cal_cell;
u8 cal[16];
nvmem_cell_get_by_name(dev, "calibration", &cal_cell);
nvmem_cell_read(&cal_cell, cal, sizeof(cal));

Because nvmem devices are not all of the same uclass, supported uclasses
must register a nvmem_interface struct. This allows CONFIG_NVMEM to be
enabled without depending on specific uclasses. At the moment,
nvmem_interface is very bare-bones, and assumes that no initialization
is necessary. However, this could be amended in the future.

Although I2C_EEPROM and MISC are quite similar (and could likely be
unified), they present different read/write function signatures. To
abstract over this, NVMEM uses the same read/write signature as Linux.
In particular, short read/writes are not allowed, which is allowed by
MISC.

The functionality implemented by nvmem cells is very similar to that
provided by i2c_eeprom_partition. "fixed-partition"s for eeproms does
not seem to have made its way into Linux or into any device tree other
than sandbox. It is possible that with the introduction of this API it
would be possible to remove it.
