Hi Christian,
This should be fixed against the latest dwc2 param rework series [1]
which i hope to get queued for 4.11. If you can give it a test, that
would be great.

John

* [PATCH v4 0/2] add support to STM LSM6DS3-LSM6DSM 6-axis Mems sensor
From: Lorenzo Bianconi @ 2017-01-10 21:55 UTC (permalink / raw)

Changes since v3:
- use I2C protocol instead of SMBus commands
- allow reading of the scale/sampling frequency whilst buffered operation is
on going
- move st_lsm6dsx_hw allocation/initialization in st_lsm6dsx_probe() in order
to avoid code duplication
- introduce enum st_lsm6dsx_hw_id to be used as I2C/SPI driver_data instead of
the device name (string)
- improve code documentation
Changes since v2:
- improve code documentation
- improve code readability
- use spi_write() instead of spi_sync_transfer() in st_lsm6dsx_spi_write()
- use SMBus commands instead of I2C protocol
- use fifo_lock mutex to prevent concurrent access to hw FIFO instead of
disabling/enabling irq line in st_lsm6dsx_flush_fifo()
- rename ring occurrences in buffer ones
Changes since v1:
- add sw fifo support
- drop trigger dependency
- use iio_claim_direct_mode() routine instead of grabbing the mutex directly
- use more unique prefix for all defines
- use info_mask_shared_by_all element for sampling_frequency
- use devm_iio_* routines
- use of_match_ptr instead of access directly to of_match_table
- fix device tree binding
- rename st_lsm6dsx_dev in st_lsm6dsx_hw
- cosmetics

this error comes because the patches I pointed out have not been
applied yet. I guess you can ignore them as long as you tested
yours on top those patches.

Bind/unbind works very well in testing. Only thing we have to figure out is
how to stop the driver loading during BMC boot... but I don't think the
solution will be in this patch set. I'll put together a v2 for tomorrow.

oh Ok. I see you added it to
"[PATCH 16/21] usb: dwc2: Remove platform static params" [0].
Yes, I think this should work nicely. Thank you very much for
your time, even though it's just for like "one old board" :-).
Do you have a public git tree with your patches that I can
clone/checkout? If not, I'll take some time on the weekend
for this and write back on monday. But yeah, this should
work.

This will never happen, tm is already checked multiple times (up to

You don't need to resend the whole series, just this patch. I'll take
2/8 and 3/8, the other ones can go through the stm32 tree.

Hmm... I had intended to use this patch for EDP reference clock, but we
don't need to change the parent
clock (see the BUG: 61664).
I just woud like to add this patch to avoid getting some unavailable
MUXGRF clock and need to debug it again,
if we support it one day in future.
Thanks.

Yep that sounds ok. As I said in my replies, we don't support the edp in the
mainline kernel yet, so nothing old can break here :-)

could you just check, if we have any other grf-based muxes that we may need in
the future. Right now I only see pclkin_isp1_wrapper describing such a mux,
but it would be cool if you could check again.

msm8998 has the same combo PHY IP. We may need

* [PATCH v4 0/3] Add QorIQ LS2088A platform support
From: Abhimanyu Saini @ 2017-01-11 6:09 UTC (permalink / raw)

linux-arm-kernel-IAPFreCvJWM7uuMidbF8XUB+6BGkLq7r,
Abhimanyu Saini
This patchset adds support for the QorIQ LS2088A SoC.
LS2088A SoC is similar to LS2080A SoC with a few differences like it has A72 cores.
This patchset
- reorganize LS2088A DTS/DTSI for code reuseability
- adds LS2088A device dtsi and dts files.
Abhimanyu Saini (3):
dt-bindings: Add compatible for LS2088A QDS and RDB board
arm64: dts: freescale: ls2080a: Split devicetree for code resuability
arm64: dts: freescale: ls2088a: Add DTS support for FSL's LS2088A SoC
Changes for v4:
- Incorporated Shawn's comments by reorganizing
DTSI, moving all #include to the top and,
- add missing files
Changes for v3:
- rename dts/dtsi files
Changes for v2:
- reorganize LS2088A device tree to use common
nodes from LS2080A device trees.
- Both LS2080A and LS2088A have same hardware
controllers, so separate dt-binding patches for
pcie, gpio, dspi, qspi are not required.

LS2088A and LS2080A are similar SoCs with a few differences like
ARM cores etc.
Reorganize the LS2080A device tree to move the common nodes to:
- fsl-ls208xa.dtsi
- fsl-ls208xa-rdb.dtsi
- fsl-ls208xa-qds.dtsi

* [PATCH v4 3/3] arm64: dts: freescale: ls2088a: Add DTS support for FSL's LS2088A SoC
From: Abhimanyu Saini @ 2017-01-11 6:09 UTC (permalink / raw)

In-Reply-To: <1484114979-4664-1-git-send-email-abhimanyu.saini-3arQi8VN3Tc@public.gmane.org>
This patch adds the device tree support for FSL LS2088A SoC based on
ARMv8 architecture.
Following levels of DTSI/DTS files have been created for the LS2088A
SoC family:
- fsl-ls2088a.dtsi:
DTS-Include file for FSL LS2088A SoC.
- fsl-ls2088a-qds.dts:
DTS file for FSL LS2088A QDS board.
- fsl-ls2088a-rdb.dts:
DTS file for FSL LS2088A RDB board.

Changes for v4:
- Incorporated Shawn's comments by reorganizing
DTSI, moving all include definations to the top
- add missing files
Changes for v2:
- reorganize LS2088A device tree to use common
nodes from LS2080A device trees.
