Add VTM thermal support. In the Voltage Thermal Management Module(VTM), K3 J72XX supplies a voltage reference and a temperature sensor feature that are gathered in the band gap voltage and temperature sensor (VBGAPTS) module. The band gap provides current and voltage reference for its internal circuits and other analog IP blocks. The analog-to-digital converter (ADC) produces an output value that is proportional to the silicon temperature. Currently reading temperatures only is supported. There are no active/passive cooling agent supported. J721e SoCs have errata i2128: https://www.ti.com/lit/pdf/sprz455 The VTM Temperature Monitors (TEMPSENSORs) are trimmed during production, with the resulting values stored in software-readable registers. Software should use these register values when translating the Temperature Monitor output codes to temperature values. It has an involved workaround. Software needs to read the error codes for -40C, 30C, 125C from the efuse for each device & derive a new look up table for adc to temperature conversion. Involved calculating slopes & constants using 3 different straight line equations with adc refernce codes as the y-axis & error codes in the x-axis. -40C to 30C 30C to 125C 125C to 150C With the above 2 line equations we derive the full look-up table to workaround the errata i2128 for j721e SoC. Tested temperature reading on J721e SoC & J7200 SoC. Signed-off-by:

Some clients of DMA-Heaps probe earlier than subsys_initcall(), this can cause issues when these clients call dma_heap_add() before the core DMA-Heaps framework has initialized. DMA-Heaps should initialize during core startup to get ahead of all users. Signed-off-by:

Add a debugfs option to allow configurable halting of the wkup_m3 during suspend at the last possible point before low power mode entry. This condition can only be resolved through JTAG and advancing beyond the while loop in a8_lp_ds0_handler. Although this hangs the system it forces the system to remain active once it has been entirely configured for low power mode entry, allowing for register inspection through JTAG to help in debugging transition errors. Halt mode can be set using the enable_off_mode entry under wkup_m3_ipc in the debugfs. Suggested-by:

Allow loading of a binary containing i2c scaling sequences to be provided to the wkup_m3 firmware in order to properly scale voltage rails on the PMIC during low power modes like DeepSleep0. Proper binary format is determined by the FW in use. Code expects firmware to have 0x0C57 present as the first two bytes followed by one byte defining offset to sleep sequence followed by one byte defining offset to wake sequence and then lastly both sequences. Each sequence is a series of I2C transfers in the form: u8 length | u8 chip address | u8 byte0/reg address | u8 byte1 | u8 byteN .. The length indicates the number of bytes to transfer, including the register address. The length of each transfer is limited by the I2C buffer size of 32 bytes. Based on previous work by Russ Dill.

AM43xx support isolation of the IOs so that control is taken from the peripheral they are connected to and overridden by values present in the CTRL_CONF_* registers for the pad in the control module. The actual toggling happens from the wkup_m3, so use a DT property from thea wkup_m3_ipc node to allow the PM code to communicate the necessity for placing the IOs into isolation to the firmware.

Some boards (currently AM335x EVM-SK) provides s/w control via GPIO to toggle VTT regulator to reduce power consumption in low power state. The VTT regulator should be disabled after enabling self-refresh on suspend, and should be enabled before disabling self-refresh on resume. This is to allow proper self-refresh entry/exit commands to be transmitted to the memory. Add support for toggling VTT regulator using DT properties. Actual toggling happens in CM3 Firmware. The enable option & the GPIO pin used is collected in A8 Core and then sent to CM3 using IPC registers. Note: Here it is assumed that VTT Toggle will be done using a pin on GPIO-0 Instance. The reason is GPIO-0 is in wakeup domain. Signed-off-by:
