Initial support for access and modification of the non-volatile regions
of the bq27425 fuel gauge DesignEnergy, DesignCapacity, and
TerminateVoltage settings.
This is intended for fine tuning the fuel gauge state machine for the
respective battery specifications.

* [RESEND 2/2] arm64: dts: Add dts files for Hisilicon Hi3660 SoC
From: Chen Feng @ 2016-12-26 9:36 UTC (permalink / raw)
To: puck.chen, xuwei5, robh+dt, mark.rutland, catalin.marinas,

Cc: suzhuangluan, xuyiping
In-Reply-To: <1482744972-56622-1-git-send-email-puck.chen@hisilicon.com>
Add initial dtsi file to support Hisilicon Hi3660 SoC with
support of Octal core CPUs in two clusters(4 * A53 & 4 * A73).
Also add dts file to support HiKey960 development board which
based on Hi3660 SoC.
The output console is earlycon "earlycon=pl011,0xfdf05000".
And the con_init uart5 with a fixed clock, which already
configured at bootloader.
When clock is available, the uart5 will be modified.
Tested on HiKey960 Board.

Please do not bother with those warnings and ignore checkpatch.
We are in the process of doing an automated conversion.

Hi Jonathan,
Thanks very much for your reply , it get me great courage to continue this upstreaming .
we will make a careful analysis of your suggestion and update a new patch after a few days.
Best regards

Reading on phone so may not be that thorough!
Looks pretty good. The device abstraction makes it slightly more complicated than it needs to be. If you aren't going to follow up quickly with other device support please drop the abstraction. It can be easily readded when needed.
Various little things inline.
Thanks
Jonathan

Usual convention is to only introduce a device type specific structure when more than one device is supported. If you are going to follow up shortly with more device support then leave it but add a note to the patch description. If not please drop this abstraction.

Rob suggested dropping the "rockchip,cru" and "syscon" properties from the
example and I definitly agree with that.
Otherwise look ok to me.

pll-specific code looks good now, but please make this patch before the clock
controller in the series and move the
@@ -130,6 +152,7 @@
enum rockchip_pll_type {
pll_rk3036,
pll_rk3066,

Thanks
Heiko
PS: I will have some comments for the clock controller patch, but it's xmas,
so that may take bit still.

Your *_host_init callback should return to pci-designware its error/success
status. There is a recent patch that added this capability to all vendor
specific drivers that use pcie-designware. Please check it out and follow the
same approach:

Yes, if other board need sending one-byte command to UART1, it should
make use of qnap-poweroff driver.
However, one model of Linkstation need such kind of command, I would
like to add it in linkstation-reset driver.
Currently, there's no such usage, so if you don't like the redundant
code which sending one-byte command, I can remove in my next patch
series.
Merry Xmas and happy new year!

This patchset imports two necessary patches for Allwinner H5: CCU driver and
the pinctrl driver, both are based on the H3 ones.
Some patches of H5 dtsi file are directly taken from Andre Przywara's kernel
tree, but did more cleanup.
The Orange Pi PC 2 dtsi file is also taken there.

Based on the Allwinner H5 datasheet and the pinctrl driver of the
backward-compatible H3 this introduces the pin multiplex assignments for
the H5 SoC.
H5 introduced some more pin functions (e.g. three more groups of TS
pins, and one more groups of SIM pins) than H3.

H5 SoC has two pin controllers, one (in user manual called "CPUx") needs
a slightly advanced driver, and the other (called "CPUs") is just equal
to the on in H3, and the H3 driver can be just reused.
Select the two necessary pinctrl drivers when building kernel for
Allwinner SoCs.
Also add H5 in the option's description.

* [PATCH 4/6] arm: dts: sun8i: split Allwinner H3 .dtsi

From: Andre Przywara <andre.przywara-5wv7dgnIgG8@public.gmane.org>
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.

From: Andre Przywara <andre.przywara-5wv7dgnIgG8@public.gmane.org>
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.

[Icenowy: remove H5 mmc compatible (seems equal to A64), add H5 pinctrl
compatible, and changes for my h3-h5 dtsi refactor, commit message
change to met new arm64 naming scheme]

In-Reply-To: <20161226171156.11605-1-icenowy-ymACFijhrKM@public.gmane.org>
From: Andre Przywara <andre.przywara-5wv7dgnIgG8@public.gmane.org>
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.

* [PATCH v2] ARM: dts: sunxi: Add num-cs for A20 spi nodes

The spi0 controller on the A20 have up to 4 CS (Chip Select) while the
others three only have 1.
Add the num-cs property to each node.
The current driver doesn't read this property but this is useful for
downstream user of DTS (FreeBSD for example).

Changes in v2:
* Explain that driver doesn't support this but that it is useful
for downstream users of DTS.

I had Acks from Jonathan and Rob on v3, but dropped these due to the added
compatible properties.
Changes since v3:
- Added compatible to sub-nodes, per Lee's requested to treat them as separate
pieces.
