The numbering of the i2c busses differs from ACPI and a number of typos
was made in the original patch. Further more the irq flags for the

client devices active in any one device.

Also label the various devices, for easier comparison with the ACPI

arm64: dts: qcom: sc7180-trogdor: Make pp3300_a the default supply for pp3300_hub

The trogdor design has two options for supplying the 'pp3300_hub' power
rail, it can be supplied by 'pp3300_l7c' or 'pp3300_a'. The 'pp3300_a'
path includes a load switch that can be controlled through GPIO84.
Initially trogdor boards used 'pp3300_l7c' to power the USB hub, newer
revisions (will) use 'pp3300_a' as supply for 'pp3300_hub'.

Add a DT node for the 'pp3300_a' path and a pinctrl entry for the GPIO.
Make this path the default and keep trogdor rev1, lazor rev0 and rev1
on 'pp3300_l7c'. These earlier revisions also allocated the GPIO to the
purpose of controlling the power switch, so there is no need to limit
the pinctrl config to newer revisions. Remove the platform-wide
'always/boot-on' properties from 'pp3300_l7c' and add them to the
boards that use this supply. Also delete the 'always/boot-on'

Commit 22337b91022d ("arm64: dts: qcom: sc7180: Changed polling mode

zone reaches a trip point, which makes regular polling below the passive
trip point temperature unnecessary. However the situation is different
when passive cooling is active, regular polling is still needed to
trigger a periodic evaluation of the thermal zone by the thermal governor.

Change 'polling-delay-passive' back to the original value of 250 ms.

arm64: dts: qcom: sc7180: Assign numbers to eMMC and SD

After many years of struggle, commit fa2d0aa96941 ("mmc: core: Allow
setting slot index via device tree alias") finally allows the use of
aliases to number SD/MMC slots.  Let's do that for sc7180 SoCs so that
if eMMC and SD are both used they have consistent numbers across boots
and kernel changes.

Picking numbers can be tricky.  Do we call these "1" and "2" to match
the name in documentation or "0" and "1" with the assertion that we
should always start at 0 and count up?

While the "start counting at 0" makes sense if there are not already
well-defined numbers for all sd/mmc controllers, in the case of sc7180
there _are_ well defined numbers.  IMO it is less confusing to use
those and match the docs.

this bus is assumed to only support 32-bit addressing, and DMA will
have to go through a slow swiotlb in the absence of an IOMMU.

As talked about in the patch ("arm64: dts: qcom: sc7180: Provide

arm64: dts: qcom: sc7180: Provide pinconf for SPI to use GPIO for CS

When the chip select line is controlled by the QUP, changing CS is a
time consuming operation.  We have to send a command over to the geni
and wait for it to Ack us every time we want to change (both making it
high and low).  To send this command we have to make a choice in
software when we want to control the chip select, we have to either:
A) Wait for the Ack via interrupt which slows down all SPI transfers
   (and incurrs extra processing associated with interrupts).
B) Sit in a loop and poll, waiting for the Ack.

Neither A) nor B) is a great option.

We can avoid all of this by realizing that, at least on some boards,
there is no advantage of considering this line to be a geni line.
While it's true that geni _can_ control the line, it's also true that
the line can be a GPIO and there is no downside of viewing it that
way.  Setting a GPIO is a simple MMIO operation.

This patch provides definitions so a board can easily select the GPIO
mode.

NOTE: apparently, it's possible to run the geni in "GSI" mode.  In GSI
the SPI port is allowed to be controlled by more than one user (like
firmware and Linux) and also the port can operate sequences of
operations in one go.  In GSI mode it _would_ be invalid to look at
the chip select as a GPIO because that would prevent other users from
using it.  In theory GSI mode would also avoid some overhead by
allowing us to sequence the chip select better.  However, I'll argue
GSI is not relevant for all boards (and certainly not any boards
supported by mainline today).  Why?
- Apparently to run a SPI chip in GSI mode you need to initialize it
  (in the bootloader) with a different firmware and then it will
  always run in GSI mode.  Since there is no support for GSI mode in
  the current Linux driver, it must be that existing boards don't have
  firmware that's doing that.  Note that the kernel device tree
  describes hardware but also firmware, so it is legitimate to make
  the assumption that we don't have GSI firmware in a given dts file.
- Some boards with sc7180 have SPI connected to the Chrome OS EC or
  security chip (Cr50).  The protocols for talking to cros_ec and cr50
  are extremely complex.  Both drivers in Linux fully lock the bus
  across several distinct SPI transfers.  While I am not an expert on
  GSI mode it feels highly unlikely to me that we'd ever be able to
  enable GSI mode for these devices.

From a testing perspective, running "flashrom -p ec -r /tmp/foo.bin"
in a loop after this patch shows almost no reduction in time, but the
number of interrupts per command goes from 32357 down to 30611 (about
a 5% reduction).
