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.

Changes in v3:

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.

Following the convention of the file, could you please set status =
"disabled" here and then set it to okay in board dts file (patch 3/3)

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.
