[PATCH v2 0/4] Update of phyBOARD-Pollux-i.MX8MP

[Cem Tenruh]

Updates for the phyCORE-i.MX8MP and phyBOARD-Pollux-i.MX8MP devicetrees.
This adds CAN-FD, RS232/RS485 and USB support for phyBOARD-Pollux-i.MX8MP.
This also adds gpio-line-name properties.

Changes in v2:
 - Edited commit message (Patch 4/4)
 - Added comment to UART2 node (Patch 4/4)

[PATCH v2 1/4] arm64: dts: imx8mp-phyboard-pollux: Add and update rtc devicetree node

[Yashwanth Varakala]

The interrupt of the RTC is connected on the carrier board
phyBOARD-i.MX8MP-Pollux.

RTC trickle-charger devicetree property is dependent on the
phyboard-pollux design.

[PATCH v2 4/4] arm64: dts: imx8mp-phyboard-pollux: Disable pull-up for CD GPIO

[Yashwanth Varakala]

From: Dominik Haller <d.haller@phytec.de>

Removes the pull-up resistor from the pad's settings to keep it
consistent for all boards. We have pull-ups in hardware on all boards so we
don't need to set the additional one from the iomux controller.
