On i.MX7ULP, the resume entry and parameter are saved
in DGO_GP registers, it has two power domains, one
is normal domain, the other is SNVS domain, if M4 also
enters VLLS mode, DGO needs to be updated into SNVS
domain to avoid power lost and lead to resume fail.Signed-off-by: Anson Huang

Add fsl,wdog_b and pinmux settings.
We need to use wdog_b to trigger pmic reset, when we trigger
wdog_b reset, we should not trigger wdog_reset_b_deb.Signed-off-by: Peng Fan

A null dereference or Oops exception might occurs when reading at once the
whole content of an spi-nor of big enough size that requires an scatterlist
table that does not fit into one single page.The spi_map_buf function is ignoring the chained sg case by dereferenceing
the scatterlist elements in an array fashion. This wrongly assumes that
the allocation of the scatterlist elements are contiguous. This is true as
long as the scatterlist table fits within a PAGE_SIZE. However, for
allocation where the scatter table is bigger than that, the pages allocated
by sg_alloc might not be contigous.The sg table can be properly walked by sg_next instead of using an array.

This patch adds lpi2c bus driver to support new i.MX products
which use lpi2c instead of the old imx i2c.The lpi2c can continue operating in stop mode when an appropriate
clock is available. It is also designed for low CPU overhead with
DMA offloading of FIFO register accesses.Signed-off-by: Gao Pan

There is no card-detection pad connected for sd3 on the i.mx6 SX
EVB board. The card is assumed to be non-removable, hence, there is
no need to redetect the card during the pm callbacks. This can be
reached by including the pm-ignore-notify option on the usdhc3 device
on the dtb file.Signed-off-by: Juan Gutierrez

The usb otg2, on the SXSCM EVB board is powered up directly by the
GEN_V5 signal from the PMIC, so there is no gpio assigned.The wrong assignation was preventing the busfreq driver to switch
to any other frequency, since the usb otg2 looks to be always
active.Signed-off-by: Juan Gutierrez

Using the mdio and ethphy device that is referenced as a phy_handle

BCM WiFi driver needs to take care of card detect by itself. Using cd-post
property tells the mmc core to not detect the card automatically during
host driver probe and post it untill the client driver notifies to do it.The non-removable option is also required to fix a NULL dereference
occurred when resuming from suspend. The pm-ignore-notify parameter is
also included.Signed-off-by: Juan Gutierrez
