* [PATCH v7 2/3] ARM: dts: add TOPEET itop elite based board
From: Randy Li @ 2016-09-18 14:01 UTC (permalink / raw)
To: linux-arm-kernel
In-Reply-To: <1474207279-9662-1-git-send-email-ayaka@soulik.info>
The TOPEET itop exynos 4412 have three versions base board. The
Elite version is the cheap one without too much peripheral devices
on it.
Currently supported are serial console, wired networking(USB),
USB OTG in peripheral mode, USB host, SD storage, GPIO buttons,
PWM beeper, ADC and LEDs. The WM8960 analog audio codec is also
enabled.
The FIMC is not used for camera currently, I enabled it just for a
colorspace convertor.

* [PATCH] drm/mediatek: mark symbols static where possible
From: Baoyou Xie @ 2016-09-18 14:02 UTC (permalink / raw)
To: linux-arm-kernel
We get 4 warnings when building kernel with W=1:
drivers/gpu/drm/mediatek/mtk_hdmi.c:1089:6: warning: no previous prototype for 'mtk_hdmi_audio_enable' [-Wmissing-prototypes]
drivers/gpu/drm/mediatek/mtk_hdmi.c:1095:6: warning: no previous prototype for 'mtk_hdmi_audio_disable' [-Wmissing-prototypes]
drivers/gpu/drm/mediatek/mtk_hdmi.c:1101:5: warning: no previous prototype for 'mtk_hdmi_audio_set_param' [-Wmissing-prototypes]
drivers/gpu/drm/mediatek/mtk_hdmi.c:1627:5: warning: no previous prototype for 'mtk_hdmi_audio_digital_mute' [-Wmissing-prototypes]
In fact, both functions are only used in the file in which they are
declared and don't need a declaration, but can be made static.
So this patch marks both functions with 'static'.

It is simple sound card time, we could assign different codec

* [RFC PATCH v2 0/2] adding panel claa070wp03xg support for exynos
From: Randy Li @ 2016-09-18 14:27 UTC (permalink / raw)
To: linux-arm-kernel
I am trying to add LCD panel with LVDS interface for exynos 4412 topeet
itop. That board using a bridge chip to convert the parallel RGB signal
to LVDS signal. I could make a fb0 node appear in system now. But I can't
make it work yet. redirecting the urandom to fb0 won't make anything
change in panel.
The timing for this panel is calcuated from Hyundai T7, but it looks
different to the vendor's kernel. But those timings settings is disabled, so
I decided not to use it.
I attach them as references:

It is actually a lvds panel connected through a rga-lvds bridge.
The touchscreen is communicated with i2c bus but the driver is not

Yes, that's the case. I can mention it in commit msg more explicitly.
Anyway till now, Exynos platform always used IRQ_TYPE_NONE. Also vendor
kernel uses it. However this did not affect the platform. I didn't dig
too much into it but it seemts that __irq_set_trigger wasn't called
before for these interrupts.

I wanted to fix here only the error itself. Using GIC_SPI instead of 0
is not related so I replaced it in separate patches [1]. Keeping such
change separate makes testing easy - dtx_diff.

The description does not convince me and I do not see an example using
this. Could you provide one?

* [PATCH 1/2] net: ethernet: broadcom: bcm63xx: use phydev from struct net_device
From: Philippe Reynes @ 2016-09-18 14:59 UTC (permalink / raw)
To: linux-arm-kernel
The private structure contain a pointer to phydev, but the structure
net_device already contain such pointer. So we can remove the pointer
phydev in the private structure, and update the driver to use the
one contained in struct net_device.

Sorry, the board TOPEET iTop 4412 for exynos 4412 I posted supported
codec with I2S interface using the simple sound card. Anyway, it is no
harm to make them explicitly right? Or I have to enabled those codec
support for SMDK, which is not needed for the other board.

%pCn (and %pC) prints the clock name
%pCr prints the clock rate - I guess I could use ?%lu? and rate instead
So I do not see an issue here - I will reword the text to shorten it.
Everything else I will fix as mentioned.

* [GIT PULL 0/3] ARM: exynos: Second round of stuff for v4.9
From: Krzysztof Kozlowski @ 2016-09-18 16:39 UTC (permalink / raw)
To: linux-arm-kernel
From: Krzysztof Kozlowski <k.kozlowski@samsung.com>
Hi,
I know it is late but it is not a big pull request. Mostly DT cleanup.
One change touching clocksource was acked by Daniel Lezcano (he
mentioned it can go through arm-soc).
Some stuff moved into topic branch. No conflicts expected, no specific
order of pulling.
Best regards,
Krzysztof

Topic branch for Samsung DeviceTree cleanup for 4.9.
Replace in DT sources hard-coded values for pinctrl configuration like pull
up/down, drive strength and function. This makes the DTS easier to read,
especially that some drive strengths values are quite non-obvious.

* [PATCH 1/2] phy-sun4i-usb: Add sun4i_usb_phy_force_session_end() function
From: Hans de Goede @ 2016-09-18 16:50 UTC (permalink / raw)
To: linux-arm-kernel
The sunxi musb has a bug where sometimes it will generate a babble
error on device disconnect instead of a disconnect irq. When this
happens the musb-controller switches from host mode to device mode
(it clears MUSB_DEVCTL_SESSION and sets MUSB_DEVCTL_BDEVICE) and
gets stuck in this state.
Clearing this requires reporting Vbus low for 200 or more ms, but
on some devices Vbus is simply always high (host-only mode, no Vbus
control). The phy-sun4i-usb code already has code to force a session
end for devices without Vbus control.
This commit adds a sun4i_usb_phy_force_session_end() function exporting
this functionality to the sunxi-musb glue, so that it can force a session
end to fixup the stuck state after a babble error.

* [PATCH 2/2] musb: sunxi: Force session end on babble errors in host-mode
From: Hans de Goede @ 2016-09-18 16:50 UTC (permalink / raw)
To: linux-arm-kernel
In-Reply-To: <20160918165018.24547-1-hdegoede@redhat.com>
The sunxi musb has a bug where sometimes it will generate a babble
error on device disconnect instead of a disconnect irq. When this
happens the musb-controller switches from host mode to device mode
(it clears MUSB_DEVCTL_SESSION and sets MUSB_DEVCTL_BDEVICE) and
gets stuck in this state.
Clearing this requires reporting Vbus low for 200 or more ms, but
on some devices Vbus is simply always high (host-only mode, no Vbus
control).
This commit calls sun4i_usb_phy_force_session_end() on babble errors
in host-mode, fixing the musb controller being stuck in this state
on systems without Vbus control; and also fixes the need to unplug
the usb-b -> usb-a cable to get out of this state on systems with
Vbus control.

* [PATCH] ARM: dts: sun8i: Enable pull-ups for bananapi-m2-plus SD slot
From: Mark Kettenis @ 2016-09-18 17:25 UTC (permalink / raw)
To: linux-arm-kernel
Board doesn't seem to have external pull-ups and some (but not all) SD cards
don't work without pull-ups.
Signed-off-by: Mark Kettenis <kettenis@openbsd.org>
---
Tested with an OpenBSD kernel where enabling the pull-ups makes an older 2G
SanDisk card work. A newer Samsung 32G microSD card doesn't seem to need
this. Note that u-boot always enables the pull-ups and boots just fine off
said 2G SanDisk card.
