Hi Florian, Andrew, Sergei,
Thanks for reviews,
Since the meson-gxl dtsi has a lot of changes pending, the patches 3, 4 & 5 will be sent in a separate patchset,
and patches 1 & 2 will be send to netdev -next.
Neil

You mean it's better to put it between "Rockchip RK3368 evb" and
"Rockchip PX5 Evaluation board"? if so, I will change it in next version.

The driver combines the two buffer ptrs and present as one single buffer. For a buffer of size 200
ptr + 0 : I I I I ... I
ptr + 100 : Q Q Q Q ... Q

There are some modes where this h/w combo can also do IQ IQ IQ pattern. Those modes are not added in the RFC patchset.

My understanding of V4L2 MPLANE constructs is limited to a quick code read only. At this point MPLANE support seems specific to video. SDR is defined as separate format like v4l2_pix_format. Questions would be - should we define new SDR_MPLANE? or merge SDR format with pix format & reuse existing MPLANE with some SDR extensions (if possible)? These seem big design decisions. Any suggestions please?
For my use case, MPLANE support does not seem to add significant benefit except it may be syntactically correct. I am doing cyclic DMA with a small set of h/w buffers and copying each stage to one mmapped vmalloc vb2_buffer at two offsets. If we add MPLANE support, it can be two non-contiguous buffer pointers.

Thanks for noticing this.
There is no need to repost to update the subject, but for reference I would
prefer the prefix to be "ARM: dts: alt:". Assuming there are no other
changes I can fix that up when queuing up this change.
I am wondering if this should be queued up as a fix for v4.9 and in turn
v4.8-stable. Or if it should just be queued up for v4.10.
In the case of the former I'd advocate adding the following tag
(again no need to repost just to update this):
Fixes: 56ed4bb984ac ("pinctrl: sh-pfc: r8a7794: Add DU pin groups")

This patch adds lsi / lse oscillators. These clocks can be use by
RTC clocks.
The clock drivers needs to disable the power domain write protection using
syscon / regmap to enable these clocks.

please split this into a separate patch, as code and dts changes need to go
through different branches.

* [PATCH v15 4/4] arm: dts: mt2701: Use real clock for UARTs

We used to use a fixed rate clock for the UARTs. Now that we have clock
support we can associate the correct clocks to the UARTs and drop the
26MHz fixed rate UART clock.

In infrasys and perifsys, there are many reset
control bits for kinds of modules. These bits are
used as actual reset controllers to be registered
into kernel's generic reset controller framework.

* [PATCH v15 0/4] Add clock support for Mediatek MT2701
From: Erin Lo @ 2016-11-04 7:43 UTC (permalink / raw)
To: Matthias Brugger, Mike Turquette, Stephen Boyd, Rob Herring
Cc: Arnd Bergmann, Sascha Hauer, Daniel Kurtz, Philipp Zabel,
devicetree, linux-arm-kernel, linux-kernel, linux-mediatek,
linux-clk, srv_heupstream, ms.chen, robert.chou
This series is based on v4.9-rc1, add clock and reset controller support
for Mediatek MT2701.
changes since v14:
- Correct commit messages of dts.
- Refine style of init/probe functions.
- Get reg addresses from platform_get_resouce() and devm_ioremap_resource().

changes since v10:
- Remove COMMON_CLK dependency from clk/mediatek/Kconfig.
changes since v9:
- Rebase to v4.8-rc1.

changes since v8:
- Rebase to v4.7-rc1.
- Include mt2701-resets.h in mt2701.dtsi.
- Remove an unused property from apmixedsys DT node.
changes since v7:
- Rebase to clk-next.
- Implement subsystem clocks in seperated files.
- Replace critical clock enabling with CLK_IS_CRITICAL flag.
- Reduce most clock registrations in CLK_OF_DECLARE().
- Remove __init and __initconst from most init fucntions and data,
and replace driver registration with platform_driver_register().
- Replace some common function or variable names with unique names.
- Use real clock for UARTs.
changes since v6:
- Rebase to v4.6-rc1.
- Register subsystem clocks in probe() instead of CLK_OF_DECLARE().
- Add clocks that referred by subsystem clocks.
- Fix clk_data size of apmixedsys.
- Add config options for each subsystem clock provider.
changes since v5:
- Rebase to v4.5-rc1 and [1].
- Enable critical clocks for MT2701
- Refine dt-binding documents, add reset controller support for hifsys.
changes since v4:
- Rebase to v4.5-rc1.
- Remove CLK_SET_RATE_PARENT from divider flags.
- Add img_jpgdec_smi clock.
- Move clk/mediatek/Kconfig into menu section in clk/Kconfig.
changes since v3:
- Change the parent of mm_mdp_bls_26m from clk26m to pwm_sel.
changes since v2:
- Fix ethsys definition.
- Replace read-modify-write with regmap_update_bits() in clock operations.
- Move mt2701-resets.h to include/dt-bindings/reset/.
- Add hifsys reset patch from John Crispin.
changes since v1:
- Document MT2701 compatible strings.
