[PATCH v2 00/10] Add Basic SoC support for MT6797

[Mars Cheng]

This patch set adds basic SoC support for mediatek's first 10-core
chip, X20, also known as MT6797.

- based on 4.10-rc2
- support multiple base address for sysirq
- support common clk

Changes since v1:
- add multiple base addresses support, v1 only allow 2 bases
- clean up clk driver

[PATCH v2 02/10] irqchip: mtk-sysirq: extend intpol base to arbitrary number

[Mars Cheng]

Originally driver only supports one base. However, MT6797 has
more than one bases to configure interrupt polarity. To support
possible design change, here comes a solution to use arbitrary
number of bases.

That's exactly why I positively hate these GIC_CPU_MASK_SIMPLE() and co.
They just hide all kind of sins:
- With GICv1/v2, this field can only be 8bit wide. Good luck shoving 10
CPUs there.
- GICv3 *doesn't* have any affinity bitmap in the binding (it can be
expressed in a very different way).

So please get rid of this GIC_CPU_MASK_SIMPLE, it is just wrong.

There is no point in this. It can either be implied by the compatible 
string or you just try to get the resource for the 2nd region. (Or in DT 
terms, get the size of reg.)

Originally I try to mimic #redistributor-regions in
Documentation/devicetree/bindings/interrupt-controller/arm,gic-v3.txt.

But I think you are right since irq-gic-v3 has several kinds of bases in
reg so that they need an indicator to decode. For irq-mtk-sysirq, we can
just try 2nd region and increment a counter to get the number of bases.

Will fix this in v3.

Thanks.

Two questions:
- What guarantees that two successive regions deal with consecutive
interrupts? For example, if I have region A that deals with interrupts
0-31, what guarantees that region B covers 32-63?
- Given that there is a static relation between a region and a hwirq,
can't you compute this relation at init time, and let set_type be a fast
path?

Why do you have a writel here, while you're using relaxed accessors
otherwise? Is there anything else that needs to be made visible to the
irqchip?

Two questions:
- What guarantees that two successive regions deal with consecutive
interrupts? For example, if I have region A that deals with interrupts
0-31, what guarantees that region B covers 32-63?
- Given that there is a static relation between a region and a hwirq,
can't you compute this relation at init time, and let set_type be a fast
path?

It is guaranteed by mediatek's chip design team. For those chips with
multiple bases, they all have the consecutive interrupts in the next
region.

sure, I can do this to optimize set_type. will do it in v3

before we call spin_unlock_irqrestore() in the end of set_type, polarity
should take effect so we use writel() here. This patch did not change
the usage.

Got it, but another warning (prefer 75 char in single line) would pop

Got it, but another warning (prefer 75 char in single line) would pop
up. Would you still like me to keep it on a single line?

That's not what I mean. writel has a DSB *before* performing the write
to the device. Do you have any write (to memory) that needs to be made
visible to the irqchip before the write to the register occurs?

Looking at the code, I'd say no. This is a standard device
read-modify-write sequence, no in-memory data that needs to make it
before the write occurs.

So please turn this into a writel_relaxed.

Look, no warning! More seriously, if you're really worried about this,
you can reformat it:

	chip_data->intpol_words = kcalloc(nr_intpol_bases,
					  sizeof(u32), GFP_KERNEL);

like this.
