Ok. Thanks! Can you create a MAINTAINERS entry so you will get
automatically CCed on patches touching your driver?

Sorry for the delay.
I've checked the known errata and confirmed that it wont
affect this use case. And we haven't been able to hit this
issue on our HW (with eeprom slave devices).
I will add my colleague looking into this further to debug.

* [PATCH] i2c: stm32: Fixes multibyte transfer for STM32F4 I2C controller
From: Pierre Yves MORDRET @ 2017-12-07 13:23 UTC (permalink / raw)

In-Reply-To: <20171207105229.jxxyfofsgub27nip@ninjato>
I do believe some investigation has to be done prior merging this patch.
The impact is genuine and has to be tested thoroughly before granting an ack.
Thus I prefer having a better understanding of the issue.
I will try to work on this later on.

Now that these registers are written at stream start, shouldn't you omit
the writes here?
Further on, it would appear that the registers that contain the format
configuration, also will contain the command to start streaming. If this is
the case, shouldn't this be the last operation in the streaming start
sequence?

No, I am waiting to send my initial 4.16 pull to arm-soc and wanted to
clarify what (if anything) from this series can still go into that pull.

Yeah, but that does not mean the patch is merged. Do you mean it is
merged in arm-soc, so it is visible in linux-next?

I will take patches 2-4.

* [PATCH V7 12/12] arm64: dts: add clocks for SC9860
From: Chunyan Zhang @ 2017-12-07 12:57 UTC (permalink / raw)
To: linux-arm-kernel
In-Reply-To: <20171207125715.16160-1-chunyan.zhang@spreadtrum.com>
Some clocks on SC9860 are in the same address area with syscon devices,
those are what have a property of 'sprd,syscon' which would refer to
syscon devices, others would have a reg property indicated their address
ranges.

* [PATCH V7 11/12] arm64: dts: add syscon for whale2 platform
From: Chunyan Zhang @ 2017-12-07 12:57 UTC (permalink / raw)
To: linux-arm-kernel
In-Reply-To: <20171207125715.16160-1-chunyan.zhang@spreadtrum.com>
Some clocks on SC9860 are in the same address area with syscon
devices, the proper syscon node will be quoted under the
definitions of those clocks in DT.

* [PATCH V7 09/12] clk: sprd: Add dt-bindings include file for SC9860
From: Chunyan Zhang @ 2017-12-07 12:57 UTC (permalink / raw)
To: linux-arm-kernel
In-Reply-To: <20171207125715.16160-1-chunyan.zhang@spreadtrum.com>
This file defines all SC9860 clock indexes, it should be included in the
device tree in which there's device using the clocks.

+Spreadtrum Clock Binding
+------------------------
+
+Required properties:
+- compatible: should contain the following compatible strings:
+ - "sprd,sc9860-pmu-gate"
+ - "sprd,sc9860-pll"
+ - "sprd,sc9860-ap-clk"
+ - "sprd,sc9860-aon-prediv"
+ - "sprd,sc9860-apahb-gate"
+ - "sprd,sc9860-aon-gate"
+ - "sprd,sc9860-aonsecure-clk"
+ - "sprd,sc9860-agcp-gate"
+ - "sprd,sc9860-gpu-clk"
+ - "sprd,sc9860-vsp-clk"
+ - "sprd,sc9860-vsp-gate"
+ - "sprd,sc9860-cam-clk"
+ - "sprd,sc9860-cam-gate"
+ - "sprd,sc9860-disp-clk"
+ - "sprd,sc9860-disp-gate"
+ - "sprd,sc9860-apapb-gate"
+
+- #clock-cells: must be 1
+
+- clocks : Should be the input parent clock(s) phandle for the clock, this
+ property here just simply shows which clock group the clocks'
+ parents are in, since each clk node would represent many clocks
+ which are defined in the driver. The detailed dependency
+ relationship (i.e. how many parents and which are the parents)
+ are implemented in driver code.
+
+Optional properties:
+
+- reg: Contain the registers base address and length. It must be configured
+ only if no 'sprd,syscon' under the node.
+
+- sprd,syscon: phandle to the syscon which is in the same address area with
+ the clock, and so we can get regmap for the clocks from the
+ syscon device.
+
+Example:
+
+ pmu_gate: pmu-gate {
+ compatible = "sprd,sc9860-pmu-gate";
+ sprd,syscon = <&pmu_regs>;
+ clocks = <&ext_26m>;
+ #clock-cells = <1>;
+ };
+
+ pll: pll {
+ compatible = "sprd,sc9860-pll";
+ sprd,syscon = <&ana_regs>;
+ clocks = <&pmu_gate 0>;
+ #clock-cells = <1>;
+ };
+
+ ap_clk: clock-controller at 20000000 {
+ compatible = "sprd,sc9860-ap-clk";
+ reg = <0 0x20000000 0 0x400>;
+ clocks = <&ext_26m>, <&pll 0>,
+ <&pmu_gate 0>;
+ #clock-cells = <1>;
+ };

* [PATCH V7 06/12] clk: sprd: add composite clock support
From: Chunyan Zhang @ 2017-12-07 12:57 UTC (permalink / raw)
To: linux-arm-kernel
In-Reply-To: <20171207125715.16160-1-chunyan.zhang@spreadtrum.com>
This patch introduced composite driver for Spreadtrum's SoCs. The
functions of this composite clock simply consist of divider and
mux clocks.

* [PATCH V7 04/12] clk: sprd: add mux clock support
From: Chunyan Zhang @ 2017-12-07 12:57 UTC (permalink / raw)
To: linux-arm-kernel
In-Reply-To: <20171207125715.16160-1-chunyan.zhang@spreadtrum.com>
This patch adds clock multiplexor support for Spreadtrum platforms,
the mux clocks also can be found in sprd composite clocks, so
provides two helpers that can be reused later on.

* [PATCH V7 03/12] clk: sprd: add gate clock support
From: Chunyan Zhang @ 2017-12-07 12:57 UTC (permalink / raw)
To: linux-arm-kernel
In-Reply-To: <20171207125715.16160-1-chunyan.zhang@spreadtrum.com>
Some clocks on the Spreadtrum's SoCs are just simple gates. Add
support for those clocks.

* [PATCH V7 01/12] drivers: move clock common macros out from vendor directories
From: Chunyan Zhang @ 2017-12-07 12:57 UTC (permalink / raw)
To: linux-arm-kernel
In-Reply-To: <20171207125715.16160-1-chunyan.zhang@spreadtrum.com>
These macros are used by more than one SoC vendor platforms, avoid to
have many copies of these code, this patch moves them to the common
header file which every clock drivers can access to.
