[cip-dev] [PATCH 4.19.y 00/29] Add further support for the RZ/G2M

[Fabrizio Castro]

Dear All,

this series adds further support for the RZ/G2M SoC
(a.k.a. R8A774C0), including IPMMU, VIN, CSI2, Sound, PWM,
and Thermal.

Thanks,
Fab

[cip-dev] [PATCH 4.19.y 02/29] iommu/ipmmu-vmsa: Modify ipmmu_slave_whitelist() to check SoC revisions

[Fabrizio Castro]

From: Yoshihiro Shimoda <yoshihiro.shimoda.uh@renesas.com>

commit b7ee92c6ff0e023a473b2500d771f6bf504fcc1a upstream.

Some R-Car Gen3 SoCs has hardware restrictions on the IPMMU. So,
to check whether this R-Car Gen3 SoC can use the IPMMU correctly,
this patch modifies the ipmmu_slave_whitelist().

[Fabrizio Castro]

commit f74e5a32fa0c03d9f4bb84ea20d0c7be34fe3725 upstream.

According to the RZ/G2 User's manual, RZ/G2E and R-Car E3 VIN
blocks are identical, therefore use R-Car E3 definitions to add
RZ/G2E support.

[cip-dev] [PATCH 4.19.y 11/29] media: rcar-csi2: Handle per-SoC number of channels

[Fabrizio Castro]

From: Jacopo Mondi <jacopo+renesas@jmondi.org>

commit 87c6f1b57f61e83392dcb6b2e4398d444e83c7c8 upstream.

The R-Car CSI-2 interface has a number of selectable 'channels' that
provides pixel data to the VINs during image acquisition.

Each channel can be used to match a CSI-2 data type and a CSI-2 virtual
channel to be routed to output path.

Different SoCs have different number of channels, with R-Car E3 being the
notable exception supporting only 2 of them.

[cip-dev] [PATCH 4.19.y 12/29] media: rcar-csi2: Fix PHTW table values for E3/V3M

[Fabrizio Castro]

From: Jacopo Mondi <jacopo+renesas@jmondi.org>

commit aa8a1012ba624e92fd1ab58463f22501bce78af8 upstream.

The PHTW selection algorithm implemented in rcsi2_phtw_write_mbps() checks for
lower bound of the interval used to match the desired bandwidth. Use that
in place of the currently used upper bound.

According to the RZ/G2 User's manual, RZ/G2E and R-Car E3 CSI-2
blocks are identical, therefore use R-Car E3 definitions to add
RZ/G2E support.

 ------------------------
 
 The R-Car CSI-2 receiver device provides MIPI CSI-2 capabilities for the
-Renesas R-Car family of devices. It is used in conjunction with the
+Renesas R-Car and RZ/G2 family of devices. It is used in conjunction with the
 R-Car VIN module, which provides the video capture capabilities.
 
 Mandatory properties
 --------------------
  - compatible: Must be one or more of the following

commit 4aac2bf0760d359af44e423dc01e10880d9d18b0 upstream.

Enable the R-Car thermal driver as a built-in.
This seems safer than enabling as a module from the point of view of
protecting equipment from overheating.

This driver is used in conjunction with the R-Car V3M (r8a77970),
E3 (r8a77990) and D3 (r8a77995) SoCs.

I just want to make sure "soc_device_match(soc_rcar_gen3) &&" deletion

Would common compatible "renesas,something...-generation2-csi2" make sense?

No objections here, but...

...make sure your hardware can protect itself when kernel fails for
whatever reason. Yes, crashes from time to time, and then thermal
support will fail, too.

It is. I wasn't sure about backporting patch 807596491d33d016e420d217cf1350aef2d2b3f7,
but It didn't seem to add any value, what's your take on that?

It is usually the case, but unfortunately with this IP every SoC needs some sort of part number specific
configuration. We reuse rcar_csi2_info_r8a77990 here only because the r8a774c0 and the r8a77990
come with the same implementation for CSI2.

My understanding is that the unit is programmed to always output from
pins VTHSENSE and VTHREF (as in like the THIDLE bits are always 00),
therefore it's down to the PCB design to pick this up properly. A kernel
crash will prevent a graceful shutdown.

Biju, you had a deeper look into this a while back, is my understanding correct?

As you wrote, there are no changes that have an impact.
But these these commits are like a set If I look at the content eatch commit.

I have actually confused RZ/G2E with RZ/G2M, therefore s|RZ/G2M|RZ/G2E|

Thankfully, this is only the cover letter.
