[ Upstream commit d6c6b85bf5582bbe2efefa9a083178b5f7eef439 ]

The L9A regulator is used to further control voltage regulators on the
board. It can be used to disable VBAT_mains, 1.8V, 3.3V, 5V rails). Make
sure that is stays always on to prevent undervolting of these volage
rails.

arm64: dts: qcom: qrb4210-rb2: switch I2C2 to i2c-gpio

commit f77e7bd40c3c2d79685e9cc80de874b69a976f55 upstream.

arm64: dts: qcom: qrb4210-rb2: switch I2C2 to i2c-gpio

commit f77e7bd40c3c2d79685e9cc80de874b69a976f55 upstream.

On the Qualcomm RB2 platform the I2C bus connected to the LT9611UXC
bridge under some circumstances can go into a state when all transfers
timeout. This causes both issues with fetching of EDID and with
updating of the bridge's firmware. While we are debugging the issue,
switch corresponding I2C bus to use i2c-gpio driver. While using
i2c-gpio no communication issues are observed.

This patch is asusmed to be a temporary fix, so it is implemented in a
non-intrusive manner to simply reverting it later.

arm64: dts: qcom: qrb4210-rb2: don't force usb peripheral mode

[ Upstream commit 27c2ca90e2f34cd3c4849af996e1a96a69e700d3 ]

The rb2 only has a single USB controller, it can be switched between a
type-c port and an internal USB hub via a DIP switch. Until dynamic
role switching is available it's preferable to put the USB controller
in host mode so that the type-A ports and ethernet are available.
