Define the pinctrl nodes for the WiFi interrupts, correct the pinctrl
for the ethernet according to the schematic, and add the clk32k_in
control for the RTC. Add the correct regulator mapping for the PCIE
too.

way too much completely different things to stuff into one patch.
- Adding the sdio wifi is one
- ethernet is next ... you're not fixing, but removing the pinctrl?
- pcie2 fixes is another one
- and the clkin32k as well

Sorry, to me this seemed like a few tiny fixes that, excluding the pcie
regulator addition, all related to correcting pinctrl definitions. I'll
be happy to split it up if need be. The SDIO wifi is really just adding
the interrupt pin... there was just a bit of stuff to add on top so I
could define it correctly; for ethernet I'm replacing the reset pin with
the PCIE port reset pin and adding other PCIE pins defined in the
schematic, and the clk32k_in is just adding another pin to note that the
RTC output is connected to that pin.
Thank you,
Chris

Once the DLL_STRBIN_TAPNUM_DEFAULT is set to the correct value [1], the
workaround to ensure stable eMMC operation is no longer needed. I
have observed testing this that hdparm went from:
"Timing buffered disk reads: 502 MB in 3.00 seconds = 167.14 MB/sec"
to the following:
"Timing buffered disk reads: 832 MB in 3.00 seconds = 277.32 MB/sec"

This needs the patch you linked to, to actually work, so I'll drop
the fixes tag when applying, because this should likely not be
backported to older kernels.
Same reasoning for patch 5.

Thank you, I wasn't sure about that or not. I can say with certanty
you don't want the eMMC device tree changes prior to that patch going
through or bad things will happen.

When the device was first added, there was a problem with the bluetooth
controller that manifested when DMA was enabled for the underlying UART
interface. At some point in the intervening time the problem appears to
have been resolved. Add the UART rx and tx channels back to re-enable
UART.
