* [PATCH 13/22] mtd: nand: lpc32xx: return error code of nand_scan_ident/tail() on error
From: Masahiro Yamada @ 2016-11-04 10:43 UTC (permalink / raw)
To: linux-arm-kernel
In-Reply-To: <1478256190-7452-1-git-send-email-yamada.masahiro@socionext.com>
The nand_scan_ident/tail() returns an appropriate error value when
it fails. Use it instead of the fixed error code -ENXIO.

* [PATCH 00/22] mtd: nand: return error code of nand_scan(_ident, _tail) on error
From: Masahiro Yamada @ 2016-11-04 10:42 UTC (permalink / raw)
To: linux-arm-kernel
nand_scan(), nand_scan_ident(), nand_scan_tail() return
an appropriate negative value on error.
Most of drivers return the value from them on error,
but some of them return the fixed error code -ENXIO
(and a few return -ENODEV).
This series make those drivers return more precise error code.

How about keeping this debug message, I think it would be useful
to leave that information in the debug logs.

looks good, the only thing I can also change myself is moving the board in the
rockchip.txt to the block of Rockchip boards (i.e. sorting by manufacturer and
board name).

* [PATCH v3] iommu: arm-smmu: Set SMTNMB_TLBEN in ACR to enable caching of bypass entries
From: Nipun Gupta @ 2016-11-04 9:55 UTC (permalink / raw)
To: linux-arm-kernel
The SMTNMB_TLBEN in the Auxiliary Configuration Register (ACR) provides an
option to enable the updation of TLB in case of bypass transactions due to
no stream match in the stream match table. This reduces the latencies of
the subsequent transactions with the same stream-id which bypasses the SMMU.
This provides a significant performance benefit for certain networking
workloads.
With this change substantial performance improvement of ~9% is observed with
DPDK l3fwd application (http://dpdk.org/doc/guides/sample_app_ug/l3_forward.html)
on NXP's LS2088a platform.
Signed-off-by: Nipun Gupta <nipun.gupta@nxp.com>
---
Changes for v2:
- Incorporated Robin's comments on v1 related to
Setting SMTNMB_TLBEN in ACR only for MMU-500 as ACR is implementation dependent
Code comments and Naming convention
Changes for v3:
- Added correct patch version

* [PATCH] ARM: S3C24XX: Add DMA slave maps for remaining s3c24xx SoCs
From: Sylwester Nawrocki @ 2016-11-04 9:45 UTC (permalink / raw)
To: linux-arm-kernel
This patch adds DMA slave map tables for the remaining s3c24xx
SoC types so the whole platform can be switched to the new API.
A few devices for which there was no DMA support with current
code are omitted from the tables.

* [PATCH 2/9] ARM: shmobile: only call rcar_gen2_clocks_init() if present
From: Simon Horman @ 2016-11-04 9:44 UTC (permalink / raw)
To: linux-arm-kernel
In-Reply-To: <cover.1478251657.git.horms+renesas@verge.net.au>
From: Simon Horman <horms@verge.net.au>
The RZ/G1M (r8a7743) uses the R-Car Gen2 core, but not the R-Car Gen2 clock
driver. This is a harbinger of a transition for R-Car Gen2 SoCs. As the
process to get all the required pieces in place is somewhat complex it
seems useful to try to disentangle dependencies where possible.
The approach here is to temporarily disable calling rcar_gen2_clocks_init()
if no R-Car Gen2 SoC are configured and thus the symbol will not be
present.

* [PATCH 28/29] ARM: dts: r8a7779: marzen: Configure pinmuxing for the DU0 input clock
From: Simon Horman @ 2016-11-04 9:44 UTC (permalink / raw)
To: linux-arm-kernel
In-Reply-To: <cover.1478252308.git.horms+renesas@verge.net.au>
From: Laurent Pinchart <laurent.pinchart+renesas@ideasonboard.com>
DU0 uses an externally provided clock, but the corresponding pin isn't
correctly muxed. Fix it.

ARM: dts: r8a7794: remove Z clock (2016-11-04 10:36:47 +0100)
----------------------------------------------------------------
Renesas ARM Based SoC DT Updates for v4.10
Clean-Ups and Corrections:
* Removed Z clock from r8a7794 SoC; it is not present in hardware
* Use generic pinctrl properties in SDHI nodes in gose board
* Correct W=1 dtc warnings on r8a7794 SoC
* Correct DU reg property on r8a7779 SoC
* Correct SCIFB reg properties to cover all registers
Enhancements:
* Configure pinmuxing for the DU0 input clock on the Marzen board
* Enable VIN 0 - 2 on r8a7793 SoC
* Enable HDMI input on Koelsch and Lager boards
* Enable SDHI1 on rskrza1 board
* Add MMCIF nodes to r7s72100 SoC
* Add MSIOF clocks to r8a7792 SoC
* Enable UHS for SDHI 0 & 1 on koelsch and alt boards
