The following patches add support for UHS modes for TI's j721e and j7200
boards.
Patches 1-3 add support for gpios to j7200-evm
Patches 4-6 add support for voltage regulators for required by the
SD card in both devices as well as enable UHS modes at 1.8V
Patches 5-6 add some required configs to the arm64 defconfig.
This series depends on driver patches adding tuning support here:

There are 4 instances of gpio modules in main domain:
gpio0, gpio2, gpio4 and gpio6
Groups are created to provide protection between different processor virtual
worlds. Each of these modules I/O pins are muxed within the group. Exactly
one module can be selected to control the corresponding pin by selecting it
in the pad mux configuration registers.
This group pins out 69 lines (5 banks).
Add DT modes for each module instance in the main domain.

Similar to the gpio groups in main domain, there is one gpio group in
wakeup domain with 2 mdoules instances in it. The gpio group pins out
73 pins (5 banks). Add DT nodes for these 2 gpio module instances.

There are 6 gpio instances inside SoC with 2 groups as show below:
Group one: wkup_gpio0, wkup_gpio1
Group two: main_gpio0, main_gpio2, main_gpio4, main_gpio6
Only one instance from each group can be used at a time. So use main_gpio0
and wkup_gpio0 in current linux context and disable the rest of the nodes.

Add support for UHS modes for the SD card connected at sdhci1. This
involves adding regulators for voltage switching and power cycling the
SD card and removing the no-1-8-v property.

defconfig patches can be posted independent of dts patches, they go to
different branches.
Also, These are a little too late for 5.10 at this point.

I was trying to follow Arnd's advice here:
https://lore.kernel.org/linux-arm-kernel/CAK8P3a1JpCCCV-CVQj3+eMfWF+=4AuHPpv390Tyj2pKn63_ZVg@mail.gmail.com/
He says that defconfig patches can be sent at the same time as dts updates and maintainers can send those
as separate pull requests.
Thanks,
Faiz

BTW, [1] your patches 7/8 and 8/8 never hit the mailing list, So, I am
commenting on the defconfig patches without actually seeing the patches,
and solely based on $subject in the cover letter.
The reason for my comment was that I think defconfig series could go
independent of the remaining series into 5.10, since they are not
related specifically to this series, they are probably needed even for
am654 and j721e nodes that already exist and was a miss that we didn't
enable. Tying that to this specific series didn't make sense to me.
But either way, we are way past rc7. I don't have enough time for
these patches to bake in -next to make it to 5.10 window. So, lets try
reposting this after rc1 tag is done so that I can send the defconfig
(separately for 5.10 window) and the dts staged towards 5.11 (and no,
I don't consider the dts patches as fixes - they are enabling the next
level of functionality).

This is weird. They are there in my patches/ folder and I always do a "git send-email patches/* ..."
Not sure why they didn't get sent. My last send-email command does have all the patches being sent:

You're right that they are not tied to the series.

Ok. I'll send only the defconfig patches in a new series and repost v2 of this at rc1.
