[PATCH 0/5] Enable peripherals on RZ/Five SMARC EVK

[PATCH 0/5] Enable peripherals on RZ/Five SMARC EVK

[Prabhakar]

From: Lad Prabhakar <prabhakar.mahadev-lad.rj@bp.renesas.com>

Hi All,

This patch series does the following:
* Adds L2 cache node and marks the SoC as noncoherent
* Enables IP blocks which were explicitly disabled and for
  which support is present
* Enables the configs required for RZ/Five SoC

Cheers,
Prabhakar

[PATCH 5/5] riscv: configs: defconfig: Enable configs required for RZ/Five SoC

[Prabhakar]

From: Lad Prabhakar <prabhakar.mahadev-lad.rj@bp.renesas.com>

Enable the configs required by the below IP blocks which are
present on RZ/Five SoC:
* ADC
* CANFD
* DMAC
* eMMC/SDHI
* OSTM
* RAVB (+ Micrel PHY)
* RIIC
* RSPI
* SSI (Sound+WM8978 codec)
* Thermal
* USB (PHY/RESET/OTG)

Along with the above some core configs are enabled too,
-> CPU frequency scaling as RZ/Five does support this.
-> MTD is enabled as RSPI can be connected to flash chips
-> Enabled I2C chardev so that it enables userspace to read/write
   i2c devices (similar to arm64)
-> Thermal configs as RZ/Five SoC does have thermal unit
-> GPIO regulator as we might have IP blocks for which voltage
   levels are controlled by GPIOs
-> OTG configs as RZ/Five USB can support host/function
-> Gadget configs so that we can test USB function (as done in arm64
   all the gadget configs are enabled)

[PATCH 5/5] riscv: configs: defconfig: Enable configs required for RZ/Five SoC

[Prabhakar]

From: Lad Prabhakar <prabhakar.mahadev-lad.rj@bp.renesas.com>

Enable the configs required by the below IP blocks which are
present on RZ/Five SoC:
* ADC
* CANFD
* DMAC
* eMMC/SDHI
* OSTM
* RAVB (+ Micrel PHY)
* RIIC
* RSPI
* SSI (Sound+WM8978 codec)
* Thermal
* USB (PHY/RESET/OTG)

Along with the above some core configs are enabled too,
-> CPU frequency scaling as RZ/Five does support this.
-> MTD is enabled as RSPI can be connected to flash chips
-> Enabled I2C chardev so that it enables userspace to read/write
   i2c devices (similar to arm64)
-> Thermal configs as RZ/Five SoC does have thermal unit
-> GPIO regulator as we might have IP blocks for which voltage
   levels are controlled by GPIOs
-> OTG configs as RZ/Five USB can support host/function
-> Gadget configs so that we can test USB function (as done in arm64
   all the gadget configs are enabled)

Is it really appropriate to work around a Linux software bug with a DT change
like this? Remember, the devicetrees are used by software other than Linux.

Agreed not a good idea, this worked with previous kernel version and I
wanted to make sure people using upstream kernel be aware of this
issue. As you mentioned this is not a correct approach Im happy for
this patch to be dropped from the series.

You might or you do?

Either way, this stuff seems fine to me /shrug

I'm pretty much agnostic on that front, so I'm cool just picking up 
this.  I've got just patch 5 in my queue for testing, there's a few 
other things in front of it but it should show up on for-next soon.

Does it make sense to merge this, considering RZ/Five support depends on
NONPORTABLE, and therefore cannot be enabled in defconfig anyway?

Indeed, that's a good point.

Note that this patch (and its review) predates the NONPORTABLE
dependency.

Palmer: are you open to adding a new rzfive_defconfig[*] instead?
I see there are already other configs, so riscv seems to follow the
arm rather than the arm64 (there can be only one ring^Wdefconfig) model.

Thanks!

[*] I do hope to reserve (possibly non-upstream) renesas_defconfig
    for the army of future Renesas RISC-V SoCs that do not need a
    dependency on NONPORTABLE ;-)
