This is a sync with kernel mainline dts.
The U-Boot eMMC does not need to care about the power for Rockchip
SoCs, because if the board is using eMMC, the power will default on
(for bootrom), so the 'vmmc', 'vqmmc' is only useful for SD in U-Boot.Signed-off-by: Kever Yang

vcc5v0_host and usbhub_enable share gpio4 RK_PA3,
which is a problem during probing (the second probe
will trigger a -EBUSY, when trying to get the gpio handle).An analysis of the situation shows, that both regulators
are actually describing the same supply.This patch removes the (currenlty not successful probing)
regulator vcc5v0_host from the DTS and adds the pinctrl-*
setting to usbhub_enable.Signed-off-by: Christoph Muellner

Commit 4687919684e0 ("serial: Remove DM_FLAG_PRE_RELOC flag in various
drivers") essentially drops flag DM_FLAG_PRE_RELOC from serial_pl01x
driver for Poplar platform, because the platform falls into the
following strategy category made by the commit.Surround DM_FLAG_PRE_RELOC flag with OF_CONTROL check, for
drivers that support both statically declared devices and
configuration from device treeBefore the commit lands, Poplar platform works by statically declaring
pl011 serial device via U_BOOT_DEVICE() with DM_FLAG_PRE_RELOC flag set
in the driver. But since Poplar also supports device configuration from
device tree, the commit practically drops the flag for Poplar, and hence
breaks the platform from booting.This patch changes platform code and device tree to initiate pl011
serial device from device tree rather than static declaration, so that
above strategy about DM_FLAG_PRE_RELOC applies to Poplar, and therefore
the reported boot failure gets fixed.Reported-by: Igor Opaniuk

When DM_USB is used, either the USB controllers are bound when the DTB
is parsed (when OF_CONTROL is enabled) or they are bound using the
U_BOOT_DEVICES() macro.
In the later case, the platform data is passed in a struct ti_musb_platdata
because it cannot be read from the DTB.Signed-off-by: Jean-Jacques Hiblot

Enable DM for USB peripheral in the musb-new driver.
Also make sure that the driver can be used in the SPL.
This implies that:
* the driver must work with and without the OF_CONTROL option. That
in turn, implies that the platform data can be passed in a struct
ti_musb_platdata or be read from the dtb
* usb.o is linked in the SPL if host support is enabledAnother change is that the driver does not fail to bind (and stop the boot
process) if one of the child driver does not bind. Reporting the error is
enough. This kind of error would appear if the port is configured in the
DTS but the driver is not activated in the config.Signed-off-by: Jean-Jacques Hiblot

The sound driver pulls together the audio codec and i2s drivers in order
to actually make sounds. It supports setup() and play() methods. The
sound_find_codec_i2s() function allows locating the linked codec and i2s

At present we use a single buffer for sound which means we cannot be
playing one sound while queueing up the next. This wouldn't matter except
that a long sound (more than a second) has to be created as a single
buffer, thus using a lot of memory. To better mimic what real sound
drivers do, add support for double buffering in sandbox.Signed-off-by: Simon Glass

The i2s bus is commonly used with audio codecs. It provides a way to

The DRA7 platforms requires that the dtb used in the SPL really matches the
platform to have the best MMC performances.
To detect the board type/version an I2C EEPROM is read. This requires that
DM is initialized before the detection. As a consequence we must reset the
DM after the board detection is a new dtb would better match the platform.Signed-off-by: Jean-Jacques Hiblot
