Series Re-introduce Exynos4212 support and add Samsung Galaxy Tab 3 8.0 boards | expand

Commit Message

Artur Weber April 16, 2023, 1:34 p.m. UTC 
Introduce support for the Galaxy Tab 3 8.0 series of boards:

 - Samsung Galaxy Tab 3 8.0 WiFi (SM-T310/lt01wifi)
 - Samsung Galaxy Tab 3 8.0 3G (SM-T311/lt013g)
 - Samsung Galaxy Tab 3 8.0 LTE (SM-T315/lt01lte)

What works:

 - Display and backlight
 - Touchscreen (without touchkeys)
 - GPIO buttons, hall sensor
 - WiFi and Bluetooth
 - USB, fuel gauge, charging (partial)
 - Accelerometer and magnetometer
 - WiFi model only: light sensor

Display panel bindings are added by a separate patchset:
"[PATCH 0/3] Add Samsung S6D7AA0 panel controller driver"[1]

Your patches do not apply, so I cannot test them. Be sure you do not
bring any new dtbs_check warnings. Currently on my pending branch we are
down to four - few missing schemas.

Put reg as after compatible.

You need to convert bindings to DT schema first. I don't accept any new
usages of TXT bindings anymore, sorry.

Does not look like you tested the DTS against bindings. Please run `make
dtbs_check` (see Documentation/devicetree/bindings/writing-schema.rst
for instructions).

I stop review as for sure this was not tested against bindings.

Hi,

thank you for the review.

I'll be taking a look at the conversion (will likely submit it as a
separate patchset, since I've been looking into some minor driver-side
changes there as well...), although I have one question - who should I
list as the bindings maintainer ("maintainers" field in YAML format)? Is
this someone specific for that subsystem, or the author of the driver,
or someone else? (It's worth noting that there isn't a maintainer listed
for the lp855x driver in the MAINTAINERS file.)
Documentation/devicetree/bindings/writing-schema.rst doesn't really
mention anything about this.

Out of curiosity - should I order the children of the / node or the
pinctrl nodes by name as well?

Anyone who has interest in the device/driver, like driver maintainer,
device developers, you erc.

Yes.

These are usually by pin name.

I copied the memory bank configuration from downstream: according to
boot logs and ATAG data from the stock bootloader, there are two memory
regions: one starting at 0x40000000 (size: 1020M) and one starting at
0x80000000 (size: 1024M). Here, only the first bank is added, since the
second one doesn't work.

I tried changing the size of this first bank to the full 1024M, and it
seems to be booting fine; still, I'd rather leave this at the same size
as claimed by downstream and ATAG.

The second memory bank (anything past 0x80000000) doesn't work, as
downstream has some weird special behavior regarding it: that region
contains "page holes", and there's a check that discards every second
page frame in that region[1][2]. That also means my comment is incorrect
- indeed, 2GB of memory are passed to the kernel, but the second 1GB is
effectively halved, leaving us with 1.5GB. (That's an oversight on my
part - I wasn't aware of this when writing the DTS initially, and only
checked this more in-depth now.)

I'm not sure if there's a way to re-create this behavior in mainline;
the closest thing I can think of is making a separate entry in reg for
each of the working pages, but that would leave us with hundreds of
lines, which is not ideal... so it's much easier to just leave it unused
for now.

Best regards
Artur Weber
