a326c1d9ba Merge patch series "AM62A DWC3: Add support for USB DFU boot in OTG mode"
Siddharth Vadapalli <s-vadapalli@ti.com> says:

Hello,

This series adds support for USB DFU boot on TI's AM62A SoC which has
two instances of DWC3 USB Controllers namely USB0 and USB1. The USB0
instance of the USB Controller supports USB DFU boot:
ROM => tiboot3.bin => tispl.bin => u-boot.img

USB DFU Boot requires the USB Controller to be configured for Gadget
mode of operation. Since the USB0 instance of the DWC3 USB Controller
supports both Host and Gadget modes of operation via the Type-C interface
on the AM62A7-SK board, the device-tree specifies the "dr_mode" as "OTG".
However, there is currently no support for dynamically switching the "mode"
from Host to Gadget and vice-versa with the help of a state-machine.
The OTG mode is treated as a separate mode in itself rather than being
treated as an intermediate stage before assuming the Host/Gadget mode.
Due to this, USB DFU boot via the Type-C interface doesn't work as the
USB Controller hasn't been appropriately configured for Device/Gadget
mode of operation. One option is to change the device-tree to specify
"dr_mode" as "peripheral" and force the controller to assume the Device
role. This will imply that the U-Boot device-tree for AM62A diverges
from its Linux counterpart. Therefore, with the intent of keeping the
device-tree uniform across Linux and U-Boot, and at the same time, in
order to enable USB DFU boot in "OTG" mode with the DWC3 Controller,
the first patch in this series sets the "mode" on the basis of the
caller function, rather than using the "dr_mode" property in the
device-tree. There are only two callers of "dwc3_generic_probe()",
each of which clearly specify the expected mode of configuration.
This will enable both Host and Device mode of operation based on the
command executed by the user, thereby truly supporting "OTG"
functionality when the USB Controller supports it.

The second patch in this series adds USB DFU environment for AM62A,
enabling USB DFU Boot and USB DFU flash on AM62A.

In addition to the patches in this series, the following device-tree
changes will be required to test USB DFU on AM62A (bootph-all property
to be added to ensure that USB Controller is present at all stages
for DFU Boot):
https://gist.github.com/Siddharth-Vadapalli-at-TI/53ba02cb0ff4a09c47e920d08247065f
The above device-tree changes will be made to the Linux device-tree,
which shall ensure that the same shall be a part of U-Boot device-tree
eventually.

The USB DFU config fragments for AM62x have been used for enabling
USB DFU boot on AM62a as follows:
R5  => am62ax_evm_r5_defconfig + am62x_r5_usbdfu.config
A53 => am62ax_evm_a53_defconfig + am62x_a53_usbdfu.config

6121ca44fb usb: dwc3-generic: set "mode" based on caller of dwc3_generic_probe()
There are only two callers of "dwc3_generic_probe()", namely:
1. dwc3_generic_peripheral_probe()
2. dwc3_generic_host_probe()
Currently, the "mode" is set based on the device-tree node of the
platform device. Also, the DWC3 core doesn't support updating the "mode"
dynamically at runtime if it is set to "OTG", i.e. "OTG" is treated as a
separate mode in itself, rather than being treated as a mode which should
eventually lead to "host"/"peripheral".

Given that the callers of "dwc3_generic_probe()" clarify the expected
"mode" of the USB Controller, use that "mode" instead of the one
specified in the device-tree. This shall allow the USB Controller to
function both as a "Host" and as a "Peripheral" when the "mode" is "otg"
in the device-tree, based on the caller of "dwc3_generic_probe()".

Enable Quality of Service (QoS) blocks for Display SubSystem (DSS), by
servicing the DSS - DDR traffic from the Real-Time (RT) queue. This is
done by setting the DSS DMA orderID to greater than 7.

DDR intensive software applications can overwhelm the DSS's access to
the DDR because of their higher frequency DDR accesses. This can cause
flickering in display with certain applications running parallely if
the DSS traffic is being serviced through non-RT queue.

189e08809e clk: Propagate clk_set_rate() if CLK_SET_PARENT_RATE present
Sometimes clocks provided to a consumer might not have .set_rate
operation (like gate or mux clocks), but have CLK_SET_PARENT_RATE flag
set. In that case it's usually possible to find a parent up the tree
which is capable of setting the rate (div, pll, etc). Implement a simple
lookup procedure for such cases, to traverse the clock tree until
.set_rate capable parent is found, and use that parent to actually
change the rate. The search will stop once the first .set_rate capable
clock is found, which is usually enough to handle most cases.

4588f29ac9 arm64: imx8mp: Read values from M24C32-D write-lockable page on DHCOM i.MX8MP
The new i.MX8M Plus DHCOM rev.200 is populated with M24C32-D EEPROM
that contains an additional write-lockable page called ID page, which
is populated with a structure containing ethernet MAC addresses, DH
item number and DH serial number.

Because the write-lockable page is not present on rev.100 i.MX8MP DHCOM
SoM, test whether EEPROM ID page exists by setting up the i2c driver.

There may be multiple EEPROMs with an ID page on this platform, always
use the first one. The evaluation of the EEPROM ID page is done in two
steps. First, the content is read and checked. This is done to cache
the content of the EEPROM ID page. Second, the content is extracted
from the EEPROM buffer by requesting it.

For the ethernet MAC address the i.MX8M Plus DHCOM currently supports
parsing address from multiple sources in the following priority order:

1) U-Boot environment 'ethaddr'/'eth1addr' environment variable
2) SoC OTP fuses
3) On-SoM EEPROM

Add support for parsing the content of this new EEPROM ID page and place
it between 2) and 3) on the priority list. The new entry is 2.5) On-SoM
EEPROM write-lockable page.

Bryan Brattlof <bb@ti.com> says:

Hello Everyone!

This small series converts TI's AM65x reference board to use
CONFIG_OF_UPSTREAM and removes the unused device tree files from
arch/arm/dts.

Because it's the last board using a AM65x without enabling OF_UPSTREAM
it allows us to also remove all the SoC FDT files as well and keep a
single version of the SoC's DT files in the dts/upstream directory going
forward.

Manorit Chawdhry <m-chawdhry@ti.com> says:

It has done a re-write of the full driver and the commits aren't split
to keep the bisectability intact.

ac90089e96 clk: ti: clk-k3-pll: Add additional robustness steps to the PLL sequence
Based on the recommendation from HW team make modifications to
the sequence for more robustness.

- Unlock the PLL registers
- Enable external bypass
- Disable the PLL
- Program pllm and pllf
- Program Ref divider
- Enable other PLL controls like DSM_EN, DAC_EN,etc
- Enable calibration if available
- Enable PLL
- Wait for PLL lock and Calibration lock
- Remove external bypass

Re-write the full sequence from scratch as the previous sequence was way
off and keep it in a single commit for bisectability.

3410596b41 arm: dts: k3-*-r5: Remove clocks from mcu_timer0
Updated PLL driver sequencing requires us to use udelay in the PLL
driver as there is no poll bit to get the status of operations.
tick-timer(mcu_timer0/main_timer0) setting up the clocks for itself is
something that won't work as the PLL driver will be using udelay and
PLLs are configured during clock probe which would end up in a recursive
probe.

tick-timer being used by K3 devices are configured by ROM and we really
don't need to configure any of the clocks.

Remove the clock dependency from R5 stage as we don't need to setup
clocks for it.

55d8fc5a47 ram: k3-ddrss: drop debug() in timing-sensitive sequence
Those debug() calls might be useful, but beware. They can cause the DDR
controller to hang if we do not run the sequence quickly enough.

They usually are not an issue with upstream U-Boot and the default DDR
config, but they have become troublesome with custom DDR configs.

Drop those debug() statements that shouldn't be present in
time-sensitive code, to avoid anyone else falling into the trap.

807677f330 Merge patch series "Add OPP_LOW support for J7200"
Aniket Limaye <a-limaye@ti.com> says:

This series adds OPP_LOW spec data in k3_avs driver and enables a config
option to select the OPP_LOW performance point.

J7200 SOC supports OPP_LOW and OPP_NOM as two Operating Performance
Points as per (7.5 Operating Performance Points) section in the
Datasheet [0].
- A72SS/MSMC at 2 GHz/1GHz operation must use OPP_NOM.
- A72SS/MSMC at 1 GHz/500 MHz operation can use OPP_NOM or OPP_LOW
  voltage (though OPP_LOW voltage is recommended to reduce power
  consumption).

The actual OPP voltage for the device is read from the efuse and
updated in k3_avs_probe().

The default j7200 devicetree and k3_avs driver set OPP_NOM spec
frequency and voltage.

In the board init file, if K3_OPP_LOW config is enabled, Check if
OPP_LOW AVS voltage read from efuse is valid and update frequency (A72
and MSMC) and voltage (VDD_CPU) as per the OPP_LOW spec.

76e69974c2 arm: mach-k3: j721e-init.c: Add support for CONFIG_K3_OPP_LOW
The default j7200 devicetree and k3_avs driver set 2GHz/1GHz frequency
for A72/MSMC clks and the OPP_NOM voltage.

J7200 SOCs may support OPP_LOW Operating Performance Point:
1GHz/500MHz clks for A72/MSMC and OPP_LOW AVS voltage read from efuse.

Hence, add a config check in board_init_f() to select OPP_LOW specs:
- Check if OPP_LOW AVS voltage read from efuse is valid.
- Use the device IDs and clock IDs (TISCI docs [0]) to find the A72 and
  MSMC clock frequencies in the devicetree.
- Fixup the clock frequencies in devicetree as per OPP_LOW spec.

k3_avs driver programs the OPP_LOW AVS voltage for VDD_CPU through
k3_avs_notify_freq() callback from clk_k3.

c6a344916d misc: k3_avs: Check validity of efuse voltage data
k3_avs driver checks opp_ids when probing and overwrites the voltage
values in vd_data for the respective board. The new k3_avs_check_opp()
can be called from board files to check the efuse data and returns 0 if
valid.

Also add the same check in k3_avs_program_voltage() to error out if
the efuse data was not valid.
