This patch series collects several fixes and peripheral enhancements for TI
DM816x SoCs and the DM8168-EVM board:

- Pinctrl: add correct pullup/down enable defines for DM816X SoCs, which
  they appear to be inverted respect to OMAP2/3.
- SD: explicit pullup disable in DM8168-EVM SD card pinmuxing.
- Storage (MMC): Update MMC node settings, dropped mmc1 hwmod.
- USB: Update MUSB node, enable multipoint mode, dropped usb-otg hwmod.

Without upcoming Andreas's patch (not yet on the list) that silences the
WARN() for the missing hwmod from DT, commits in between the hwmod DT
and the code removal will get a harmless WARN() during boot.

Tested NAND on DM8168-EVM, seems the pinmuxing is working fine.
GPMC_WAIT is left with the pull-down enabled where a pull-up would be
preferable, and GPMC_WPn is not muxed (reset default). Neither causes a
functional problem.

Changes in v3:
- Collected R-b tag from Andreas.
- Split "Update USB node" to have separated hwmod and DT edits.
- Removed mmc1 hwmod, splitted in the same way as USB.
- Reorder USB reg/reg-names to match the binding, rename nodes to the mc base address.
- Dropped patch "dm816x: Correct speed for sysclk5", it requires more
  investigation.
- Link to v2: https://patch.msgid.link/20261028-patch-ektor5-dm8168-dts-v2-0-4544429251e2@linaro.org (local)

Changes in v2:
- Removed useless "Prevent USB being put into idle" patch.
- Dropped "Match up capability flags for USB" patch.
- Refactored USB node patch to use ti-sysc instead of usb_otg_hs.
- Added "Remove hwmod code for USB" patch to complete the ti-sysc
  porting.
- Using DT include instead of dt-bindings header, dropped patch.
- Link to v1: https://patch.msgid.link/20261016-patch-ektor5-dm8168-dts-v1-0-b4ce30217028@linaro.org (local)
