* [PATCH v2 2/3] clk: uniphier: add CPU-gear change (cpufreq) support
From: Masahiro Yamada @ 2016-11-24 5:57 UTC (permalink / raw)
To: linux-arm-kernel
In-Reply-To: <1479967061-25975-1-git-send-email-yamada.masahiro@socionext.com>
Core support code for CPU frequency changes, which will be used by
the generic cpufreq driver.
The register view is different from the generic clk-mux; it has
a separate status register, and an update bit to load the register
setting.

Yeah, but that quickly gives away as there are many singleton devices
and everyone tries to add theirs at the end of the list resulting in
merge conflicts.

Agree with Kevin that it would be churn. If done, it should be last
thing that gets done in a merge window. I would not attempt it in
relatively busy merge windows like this one.

One thing people haven't really noticed is that starting with
A80, A83T, H3, the DMA channel configuration registers have
been slightly changed when compared to A31/A23/A33. The DMA
burst length field offset was changed by 1.
We need to fix this.

Thats pretty bad. Sorry about that. The original justification for
keeping them enabled all the time was that they are in-SoC modules with
no external dependencies (like IO lines or voltage rails) so they can be
enabled on all boards that use DA850. While that remains true, the
configuration itself is board specific.
I think the error messages are still useful, so instead of silencing
them, I think we should go back to keeping these nodes disabled by
default and enabling only on boards which have support for it in the driver.
Thanks,
Sekhar

Thanks, but, my point is that Linux already have "of_clk_get()",
but we don't have its devm_ version.
The point is that of_clk_get() can get clock from "device_node".
Why having devm_ version become so problem ?

AFAIK ARCH_SUNXI encompasses/supersedes MACH_SUN*I.
(And I don't have to add MACH_SUN9I later :) )

I have thought about this again, I think I should keep the loop in each
type of platform timers. The benefit we can get from this are:
(1) reduce the global variables:
static struct acpi_gtdt_timer_block **timer_block __initdata;
static struct acpi_gtdt_watchdog **watchdog __initdata;
make them in thire own init function.
(2) avoid allocating and free memory in different functions.
we also can return all the GT block info in one go.

Sure. That sounds fine for now. I'll reply to your other thread
with a plan of attack on how to do the framework changes. I think
we need to do those regardless of the outcome of your
investigation.

* [RFC PATCH 5/5] arm64: dts: sunxi: add support for the Orange Pi PC 2 board
From: Andre Przywara @ 2016-11-24 1:17 UTC (permalink / raw)
To: linux-arm-kernel
In-Reply-To: <1479950235-26821-1-git-send-email-andre.przywara@arm.com>
The Orange Pi PC 2 is a typical single board computer using the
Allwinner H5 SoC. Apart from the usual suspects it features three
separately driven USB ports and a Gigabit Ethernet port.
Also it has a SPI NOR flash soldered, from which the board can boot
from. This enables the SBC to behave like a "real computer" with
built-in firmware.
Add the board specific .dts file, which includes the H5 .dtsi and
enables the peripherals that we support so far.

* [RFC PATCH 4/5] arm64: dts: sunxi: add Allwinner H5 .dtsi
From: Andre Przywara @ 2016-11-24 1:17 UTC (permalink / raw)
To: linux-arm-kernel
In-Reply-To: <1479950235-26821-1-git-send-email-andre.przywara@arm.com>
The Allwinner H5 SoC is pin-compatible to the H3 SoC, but uses
Cortex-A53 cores instead.
Based on the now shared base .dtsi describing the common peripherals
describe the H5 specific nodes on top of that.
That symlinks in the sun8i-h3-h5.dtsi from the arch/arm tree.

The sun6i DMA driver is used in the Allwinner A64 and H5 SoC, which
have arm64 capable cores. Add the generic sunxi config symbol to allow
the driver to be selected by arm64 Kconfigs, which don't feature
SoC specific MACH_xxxx configs.

* [RFC PATCH 1/5] arm: dts: sun8i: split Allwinner H3 .dtsi
From: Andre Przywara @ 2016-11-24 1:17 UTC (permalink / raw)
To: linux-arm-kernel
In-Reply-To: <1479950235-26821-1-git-send-email-andre.przywara@arm.com>
The new Allwinner H5 SoC is pin-compatible to the H3 SoC, but with the
Cortex-A7 cores replaced by Cortex-A53 cores and the MMC controller
updated. So we should really share almost the whole .dtsi.
In preparation for that move the peripheral parts of the existing
sun8i-h3.dtsi into a new sun8i-h3-h5.dtsi.
The actual sun8i-h3.dtsi then includes that and defines the H3 specific
parts on top of it.
On the way get rid of skeleton.dtsi, as recommended in that very file.

* [RFC PATCH 0/5] arm64: Allwinner H5 support
From: Andre Przywara @ 2016-11-24 1:17 UTC (permalink / raw)
To: linux-arm-kernel
This series adds support for the recently released Allwinner H5 SoC [1] and
the Orange Pi PC 2 board [2].
This exercise is rather easy this time, since the new SoC is very similar
to the existing H3 SoC and can thus share a lot of support.
To express this, the first patch splits the H3 .dtsi to allow reusing
it later. The last two patches add the H5 .dtsi and the .dts for the
first available board featuring this chip, based on that shared base DT.
This is some early version, it's based on a merge of various -for-4.10
branches from Maxime's repository.
I can boot this on the OPi board and MMC and USB seem to work fine.
I haven't tested any other peripherals yet.
Some open issues:
- The naming: Following the Allwinner scheme this should be "sun50i-h5"
(which I use in this series), but it shares so much with the H3 that
"sun8i-h5" wouldn't be wrong either. It gets a bit weird with that shared
.dtsi, which I call sun8i-h3-h5.dtsi for now.
- The clocks and pinctrl look _almost_ similar. I may sound like a broken
record, but our habit of requiring kernel support for those almost identical
SoCs really bites us now. As the MMC got updated, I fear there is _one_
additional pin that we need for the HS400 transfer mode. Also I am afraid
the MMC clock may be slightly different due to the advanced MMC support.
At the moment this is not an issue, as the driver only support DDR50 at
most anyway, so we get away with it now.
I wonder if it's feasible to add those things to the existing H3 clocks
and pinctrl to avoid another set of drivers.
- I just see that I missed those patches that add just the names to the
binding docs. I will send them once we agreed on the naming.
Let me know what you think.
Cheers,
Andre.

* [RESEND PATCH 4/6] apalis-tk1: adjust pin muxing for v1.1 hw
From: marcel at ziswiler.com @ 2016-11-24 1:04 UTC (permalink / raw)
To: linux-arm-kernel
In-Reply-To: <20161124010456.24604-1-marcel@ziswiler.com>
From: Marcel Ziswiler <marcel.ziswiler@toradex.com>
Configure Apalis MMC1 D6 GPIO on SDMMC3_CLK_LB_IN as reserved function
without any pull-up/down.
Configure GPIO_PV2 as SD1_CD# according to latest V1.1 HW.
Leave SDMMC3_CLK_LB_OUT muxed as SDMMC3 with output driver enabled aka
not tristated and input driver enabled as well as it features some
magic properties even though the external loopback is disabled and the
internal loopback used as per SDMMC_VENDOR_MISC_CNTRL_0 register's
SDMMC_SPARE1 bits being set to 0xfffd according to the TRM! This pin is
now a not-connect on V1.1 HW in order to avoid any interference.
