[PATCH 0/3] Improve K3-am625-sk support (USB, MMC)

[PATCH 0/3] Improve K3-am625-sk support (USB, MMC)

[Sjoerd Simons]

This series picks up a few patches from the TI BSP tree that
unfortunately didn't make it upstream thusfar.

The first patch improve SD card compatibility (allowing U1 class cards
to be used), the remaining ones add USB support.

The type-c connector isn't entirely modelled with these changes as
it goes through a TPS6598 PD controller. Unfortunately the dtb bindings
for that currently require an irq line, which is not connected on E1 and
E2 version boards. The patchese to support this setup unfortunately didn't land
yet[0].. As such the last patch ignored the PD controller and simply
configures usb0 as periphal only rather then mode switch capable, which
at least gives some basic usability of that USB port.

[PATCH 1/3] arm64: dts: ti: k3-am62-main: Update OTAP and ITAP delay select

[Sjoerd Simons]

From: Nitin Yadav <n-yadav@ti.com>

UHS Class U1 sd-card are not getting detected due to incorrect
OTAP/ITAP delay select values in linux. Update OTAP and ITAP
delay select values for various speed modes. For sdhci0, update
OTAP delay values for ddr52 & HS200 and add ITAP delay for legacy
& mmc-hs. For sdhci1 & sdhci2, update OTAP & ITAP delay select
recommended as in RIOT for various speed modes.

This is pretty useless without corresponding driver changes 
to pick up ti,itap-del-sel-legacy as well

Right; itap-del-sel-legacy is properly documented in the device-tree
binding and was already previously set ofcourse so i didn't pick up it
needed more driver changes. That said the dtb change itself should
still be valid even if not actually applied.

It's a Collabora branded UHS class 1 (SDR104) card; Matching the commit
message indication given by Nitin. So that in particular i guess, will
have been fixed by the change to the ti,otap-del-sel-sdr104 value for
sdhci1.

For the two patches you highlighted above; Is TI planning to upstream
those as well?

[PATCH 3/3] arm64: dts: ti: k3-am625-sk: Add support for USB

[Sjoerd Simons]

From: Aswath Govindraju <a-govindraju@ti.com>

AM62 SoC has two instances of USB and they are brought on to the board
in the following way,

-> USB0 instance
 - This is brought out to a USB TypeC connector on board through TPS6598 PD
   controller. The PD controller should decide the role based on CC pin in
   the connector. Unfortunately the irq line for the TPS isn't hooked up
   which is a mode not yet support by the driver (some patches were
   submitted earlier this year[0]). So for now the PD controller is left
   out and periphal mode chosen.

-> USB1 instance
 - This is brought out to a USB TypeA connector on board.

Therefore, add the required device tree support for the above in the board
dts file.

Really appreciate porting and posting these patches to mainline!
Wondering what tree are these patches based on?
I cannot apply cleanly on linux-next.

These are against Linux 6.1 ; I'll happy rebase agains next for the
next round or is there a specific tree you prefer to base against?

TI K3 patch queue is at:
https://git.kernel.org/pub/scm/linux/kernel/git/ti/linux.git ti-next

This is part of linux-next. So, yes, I would like all patches to be
based on -next or above tree.

I see you have already done that in v2.. Thanks!
