Hi Pankaj, Rahul, Arun,

Please split generic SoC dtsi files and board dts files into separate
patches. Also please see my comments inline.

Just to make sure, all your GPX banks are muxed type, with wake-up
interrupts muxed to a single GIC interrupt line, right?

Function 0 is input, not a special function. It shouldn't be handled
this way. If a board needs to set up pull-up/down and driver strength
for GPIO pins then it should add its own board-specific pinconf nodes
with just pin-pud and/or pin-drv properties and without pin-function.

This is inconsistent. To specify 1- and 4-bit SD busses you need to
include reference to just one pinconf node (sd0_bus1 or sd0_bus4), but
for 8-bit bus you need to specify both sd0_bus4 and sd0_bus8.

Please make the nodes exclusive, so you always need to specify all
possible configurations with given wiring (e.g. with 4 wires, you can
run in 1-bit and 4-bit modes, not just 4-bit).

Same for remaining instances of SD bus.

Please use generic fixed clock bindings. You can take [1] as an example
how to use them.

Is it the correct UART address? It seems a bit off compared to addresses
of other ports.

This is not a valid property, according to binding documentation.

Neither is this one.

This is a property of the SoC, not the board.

This won't compile, because this file hasn't been added yet by previous
patches.

Isn't it possible to reuse some of the definitions from exynos5.dtsi? How
much different is this SoC from other SoCs from the series?

@unit-address suffix must match the first entry of reg property.

You need compatible = "simple-bus" here if you need the nodes below
to be instantiated.

However I'm not sure if there is a point in placing them inside
a simple-bus. This needs more thought, so please give me a bit
more time to think over this and patches 4 and 7.

nit: Inconsistent hexadecimal character case, on Exynos in dts* files
upper case should be used.

Also the reg size looks a bit suspicious, as it's not even page aligned.
Is it the whole area used by the MCT block, not just the used registers?

MCT is not an interrupt controller.

Ditto. This is a property specific to interrupt controllers.

Why two cells are needed? Using just one woudl simplify interrupt
specifiers above and interrupt-map specifiers below.

Instead of using such comment, maybe it would be better to rename
labels of pinctrl nodes to be more meaningful, such as pinctrl_rt,
pinctrl_fsys and pinctrl_aud?

Please use generic "mmc@" names for MMC nodes and move fifo-depth property
here to SoC-level dtsi.

I will split them to SoC and Board DT patches.

There is no combiner in 5260. Each GPX bank is connected one GIC interrupt
line.

I moved this node to Board file. I hope that is correct.

Ok. I will remove "gpc0-3" from sdX_bus4.
