[PATCH 1/4] mfd: 88pm800: fix NULL pointer error

[yizhang.mrvl]

From: Yi Zhang <yizhang@marvell.com>

move "device_800_init" to fix NULL pointer error when
calling "device_gpadc_init"

for "device_gpadc_init" needs "subchip->regmap_gpadc"
to set registers via regmap interface

[PATCH 0/3] *** SUBJECT HERE ***

[Adam Thomson]

This patch set adds DT bindings support for PPS APDOs, and updates the FUSB302
to use the generic connector bindings allowing for PPS support in this Type-C
port controller. Existing FUSB302 device specific bindings still work, but
are now deprecated in favour of the generic connector approach.

Changes in v2:
	- Added Reviewed-by tags to patches
	- Rebase code against latest usb-next branch (v4.19-rc2)

Adam Thomson (3):
  dt-bindings: connector: Add support for USB-PD PPS APDOs to bindings
  dt-bindings: usb: fusb302: Use usb-connector bindings for
    configuration
  usb: typec: fusb302: Populate tcpc fwnode for TCPM property handling

Please ignore as suffering finger trouble. Will resend with patches corrected.
