[cip-dev] [PATCH 4.19.y 00/17] Add CMT and TMU support to RZ/G2E

[Fabrizio Castro]

Dear All,

this series backports what's necessary to support CMT and TMU
on the RZ/G2E.

This series depends on:

Thanks, I applied the series.

Strictly speaking patches 1, 4, 16 only alter whitespace, so they
would not be welcome under -stable rules. OTOH they clearly do not
break anything, and ammount of surrounding changes means taking them
is easier than not taking them... so I took them.

Best regards,
									Pavel

[cip-dev] [PATCH 4.19.y 02/17] clocksource/drivers/sh_cmt: Fixup for 64-bit machines

[Fabrizio Castro]

From: Sergei Shtylyov <sergei.shtylyov@cogentembedded.com>

commit 22627c6f3ed3d9d0df13eec3c831b08f8186c38e upstream.

When trying to use CMT for clockevents on R-Car gen3 SoCs, I noticed
that 'max_delta_ns' for the broadcast timer (CMT) was shown as 1000 in
/proc/timer_list. It turned out that when calculating it, the driver did
1 << 32 (causing what I think was undefined behavior) resulting in a zero
delta, later clamped to 1000 by cev_delta2ns(). The root cause turned out
to be that the driver abused *unsigned long* for the CMT register values
(which are 16/32-bit), so that the calculation of 'ch->max_match_value'
in sh_cmt_setup_channel() used the wrong branch. Using more proper 'u32'
instead fixed 'max_delta_ns' and even fixed the switching an active
clocksource to CMT (which caused the system to turn non-interactive
before).

[cip-dev] [PATCH 4.19.y 03/17] clocksource/drivers/sh_cmt: Fix clocksource width for 32-bit machines

[Fabrizio Castro]

From: Sergei Shtylyov <sergei.shtylyov@cogentembedded.com>

commit 37e7742c55ba856eaec7e35673ee370f36eb17f3 upstream.

The driver seems to abuse *unsigned long* not only for the (32-bit)
register values but also for the 'sh_cmt_channel::total_cycles' which
needs to always be 64-bit -- as a result, the clocksource's mask is
needlessly clamped down to 32-bits on the 32-bit machines...

[cip-dev] [PATCH 4.19.y 04/17] clocksource/drivers/sh_cmt: Properly line-wrap sh_cmt_of_table[] initializer

[Fabrizio Castro]

From: Sergei Shtylyov <sergei.shtylyov@cogentembedded.com>

commit eceb4c49aed0fafbc4967e788231b1eba42b7606 upstream.

There's no good reason for the sh_cmt_of_table[] initializer to
violate the 80-column limit, especially after the commit 8d50e9476bb4
("clocksource/drivers/sh_cmt: Mark "renesas,cmt-48-gen2" deprecated")
partially fixed it -- fix the R-Car gen2 related entries as well.

Also document R8A779{7|8}0 bindings as these are the R-Car gen3 SoCs for

I could not apply this, as arch/arm64/boot/dts/renesas/r8a774c0.dtsi does
not exist in my tree.

Plus, you are pushing spdx comment changes. I guess it is ok if it makes your
life easier, but...

This was depended patch in charge.
I already applied and push to linux-4.19.y-cip branch.

[cip-dev] [PATCH 4.19.y 13/17] clk: renesas: r8a774c0: Fix LAST_DT_CORE_CLK

[Fabrizio Castro]

commit e61b30bb34b6206f76e623269a41b65cd3989fff upstream.

Enum LAST_DT_CORE_CLK needs updating as R8A774C0_CLK_CANFD
was recently added and it's the core clock with the highest
index.

[cip-dev] [PATCH 4.19.y 17/17] arm64: enable CMT/TMU support for Renesas SoC

[Fabrizio Castro]

From: Sergei Shtylyov <sergei.shtylyov@cogentembedded.com>

commit c1801ad028456267dde2111e470ac43f7882debf upstream.

Renesas R-Car gen3 SoCs have both CMT and TMU timers, so we have to enable
building them in Kconfig.platforms (as they don't normally have the prompts
in Kconfig).
