[PATCH V4 0/4] arm64: dts: freescale: Add chargebyte Charge Control Y

[Stefan Wahren]

This series adds support for the chargebyte Charge Control Y, which is
an Electrical Vehicle Supply Equipment (EVSE) for MCS (Megawatt
Charging System) charging stations.

sashiko reported in the first version of the series [1] that X_nRST_LAN
is available via GPIO line names, but there is no reset mechanismn in the
device tree. This finding is valid. Since the reset line feature isn't
implemented for LAN8651 driver yet, I like to proceed with the current
version. The LAN8651 handles reset via SPI commands and in rare cases
we still have the possibility to control the reset from userspace.
Btw the pin has a pull resistor in hardware, so it's not floating.

Changes in V4:
- prepend constrains fix for ti,tcan104x-can binding (reported by sashiko)

Changes in V3:
- add Acked-by's from Conor
- add missing SD2_VSELECT to default pinctrl of SD interface (reported by sashiko)
- clarify LAN8651 GPIO usage in device tree (suggested by Frank Li)
- move X_nRST_LAN into dedicated pinctrl group to make it more self-explaining

Changes in V2:
- drop phy-can-transceiver changes and make MCP2542 compatible to TI TCAN1042
  as suggested by Marc Kleine-Budde & Frank Li
- implemented SD2_nRESET as vmmc supply for SD card interface
  (reported by sashiko)
- add UHS support for SD card interface
- dropped downstream property ti,leds-polarity (reported by sashiko)
- fix GPIO line name of X_LAN_nCS (reported by sashiko)
- drop unconnected pins (X_TDI, X_TMS_SWDIO, X_TDO) from GPIO line names
