[PATCH 00/13] Introducing the Mobileye EyeQ6Lplus SoC

[Benoît Monin]

The Eyeq6Lplus is a new system-on-chip part of Mobileye's EyeQ family
of SoC aimed at Advanced Driver Assistance Systems (ADAS). It is built
around a multicore MIPS I6500 with 2 cores and 8 threads and integrates
controllers and accelerators dedicated to driving assistance.

This patchset adds the initial support for the EyeQ6Lplus and its
evaluation board with the following list of controllers:
* The OLB ("Other Logic Block") providing clocks, resets and pin controls.
* One UART from DesignWare.
* One GPIO controller from DesignWare.
* Two SPI controllers from DesignWare, one in host mode and one in target
  mode.
* One octoSPI flash controller from Cadence, identical to the one found
  in the EyeQ5.
* Two I2C controllers from Designware.

The support for the particularities of the I2C controllers is 
currently under review[1], but basic operations (single read,
single write, write-then-read) work with the compatible fallback to
"snps,designware-i2c".

The patch series adds the device tree bindings for the SoC and the OLB. It
also adds the Kconfig entry for the EyeQ6Lplus, the SoC and evaluation
board device tree, and the defconfig. For the OLB, the series adds the
match data to the clk-eyeq, reset-eyeq and pinctrl-eyeq5 drivers.

It also brings three other changes. One for the pinctrl-eyeq5 driver to
access the pin descriptions, pin functions and pin bank register via
the match data instead of directly. This is needed to add support for
the EyeQ6Lplus alongside the EyeQ5 to the pinctrl driver.

To be able to match against compatible entries, An OF node is needed
but the pinctrl-eyeq5 does not have one as it is an auxiliary device
of clk-eyeq. As part of his MACB phy series[2], Théo switched to
devm_auxiliary_device_create() to register the auxiliary devices and this
helper sets the OF node of the auxiliary device. To avoid a dependency
between the patch series, eq5p_probe() is able to handle both cases,
having the of_node field already set in the device structure or getting
it from the parent device. After both series are merged, a cleanup of
the pinctrl-eyeq5 probe function can be done.

The two other changes are in the clk-eyeq driver. First we skip the
post-divisor when computing the PLL frequency in the clk-eyeq driver,
to match how the clock signal is wired internally in all EyeQ PLL and
compute the correct frequency for the PLL of the EyeQ6Lplus. Second we
adjust the accuracy and down spreading computation of the PLL frequency
as the spread spectrum of all EyeQ PLL is in 1/1024 and not in 1/1000
as previously thought.

[PATCH 02/13] dt-bindings: soc: mobileye: Add EyeQ6Lplus OLB

[Benoît Monin]

The "Other Logic Block" found in the EyeQ6Lplus from Mobileye provides
various functions for the controllers present in the SoC.

The OLB produces 22 clocks derived from its input, which is connected
to the main oscillator of the SoC.

It provides reset signals via two reset domains.

It also controls 32 pins to be either a GPIO or an alternate function.

[PATCH 04/13] reset: eyeq: Add Mobileye EyeQ6Lplus OLB

[Benoît Monin]

Declare the two reset domains found in the EyeQ6Lplus OLB and add
them to the data matched by 'mobileye,eyeq6lplus-olb' compatible.

Those reset domains are identical to those present in the EyeQ5
OLB, so no changes are needed to support them.

[PATCH 05/13] pinctrl: eyeq5: Use match data

[Benoît Monin]

Instead of using the pin descriptions, pin functions and register offsets
of the EyeQ5 directly, access those via a pointer to a newly introduced
struct eq5p_match_data.

This structure contains, in addition to the pin descriptions and pin
functions, an array of pin banks. Each bank holds the number of pins
and the register offsets.

All functions accessing a pin now use a pointer to a bank structure and
an offset inside that bank. The conversion from a pin number to a bank
and an offset is done in the new function eq5p_pin_to_bank_offset(),
which replace eq5p_pin_to_bank() and eq5p_pin_to_offset().

All the data related to the EyeQ5 is declared with the eq5p_eyeq5_
prefix to distinguish it from the common code.

During the probe, we now get a reference to the parent OF node if we
don't already have it and use that node to get the match data. We cannot
directly use an OF node since pinctrl-eyeq5 is an auxiliary device
of clk-eyeq.

[PATCH 06/13] pinctrl: eyeq5: Add Mobileye EyeQ6Lplus OLB

[Benoît Monin]

Add the match data for the pinctrl found in the EyeQ6Lplus OLB. The pin
control is identical in function to the one present in the EyeQ5 but
has a single bank of 32 pins.

[PATCH 07/13] clk: eyeq: Skip post-divisor when computing PLL frequency

[Benoît Monin]

The output of the PLL is routed before the post-divisor so it should be
ignored when computing the frequency of the PLL, functional change is
implemented to reflect how the clock signal is wired internally.

For the PLL of the EyeQ5, EyeQ6L, and EyeQ6H, this change has no impact
as the post-divisor is either reported as disabled or set to 1. The PLL
frequency is the same before and after the post-divisor.

For the PLL in EyeQ6Lplus, however, the post-divisor is not 1, so it must
be ignored to compute the correct frequency.

[PATCH 08/13] clk: eyeq: Adjust PLL accuracy computation

[Benoît Monin]

The spread spectrum of the PLL found in eyeQ OLB is in 1/1024 parts of the
frequency, not in 1/1000, so adjust the computation of the accuracy. Also
correct the downspreading to match.

[PATCH 09/13] clk: eyeq: Add Mobileye EyeQ6Lplus OLB

[Benoît Monin]

Declare the PLLs and fixed factors found in the EyeQ6Lplus OLB as part
of the match data for the "mobileye,eyeq6lplus-olb" compatible.

The PLL and fixed factor of the CPU are registered in early init as they
are required during the boot by the GIC timer.

[PATCH 10/13] MIPS: Add Mobileye EyeQ6Lplus SoC dtsi

[Benoît Monin]

Add the device tree include files for the EyeQ6Lplus system on chip
from Mobileye.

Those files provide the initial support of the SoC:
* The I6500 CPU and GIC interrupt controller.
* The OLB ("Other Logic Block") providing clocks, resets and pin controls.
* One UART.
* One GPIO controller.
* Two SPI controllers, one in host mode and one in target mode.
* One octoSPI flash controller.
* Two I2C controllers.

[PATCH 11/13] MIPS: Add Mobileye EyeQ6Lplus evaluation board dts

[Benoît Monin]

Add the device tree of the evaluation board of the EyeQ6Lplus SoC.

The board comes with 2GB of RAM, an SPI NAND connected to the octoSPI
controller, and the two SPI controllers are connected to each other via
an intermediate MCU for loopback testing. The UART of the SoC is used
as the serial console.

[PATCH 13/13] MAINTAINERS: Mobileye: Add EyeQ6Lplus files

[Benoît Monin]

Use wildcard to match all EyeQ defconfigs under arch/mips. This covers
the newly added defconfig, and the EyeQ5 and EyeQ6H ones. Add an entry
for the dt-bindings header of the EyeQ6Lplus clocks.

While at it, add myself to the maintainers of Mobileye MIPS SoCs.

I think a question on everyone's lips is how much new MIPS hardware
MobilEye are going to be churning out? Is there *more* coming?

Don't get me wrong - I think it is pretty cool. But as these systems have
long support cycles, this will have direct consequences for the MIPS arch
maintenance and longevity.

Indeed, I do not (and I should have known better...).

In my particular case of a microcontroller acting as an SPI "relay" on the
evaluation board, what would be the best way to describe it? It connects
the two SPI controllers of the SoC, one is a host and one is a target, so
it behave as an SPI target on one side and as an SPI host on the other.

The trivial devices bindings seems to be dedicated to devices, thus not for
SPI hosts. Do I need a dedicated binding or did I miss something I could
use for a trivial spidev slave?

The EyeQ6L family was announced in 2024[1] and this particular variant,
the EyeQ6Lplus, is from this year I guess.

I cannot say for sure what are Mobileye plans but the next platform
we are working on is based on RISC-V, with MIPS P8700 cores[2].

In DT you describe only a real device connected here, so in case of your
evalboard - nothing can be described, because there is no such real device.

That needs to be detailed and discussed with the SPI maintainer on the SPI
devel list. (Added.)

Can you illustrate with a picture or so what is going on here?

Here is what it looks like on the evaluation board of the EyeQ6Lplus:

    |                        |          |                        |
    +------------------------+          +------------------------+

(1): The MCU, when the chip select is asserted on its SPI target, starts
     a transaction on its SPI host side. It then copies data received by
     the target side to the host side.

With the spidev entries in the device tree, it is used to test that SPI
of the SoC is working with `spidev_test`. So the MCU is part of the test
harness found on the evaluation board.

If the SPI signals of the SoC had been routed to a header, we could do the
same test with jumper wires, directly connecting the host and the target.
