When an ethX port is disabled in the device tree, an error is returned
by xdp_rxq_info_reg() function while transitioning the CPSW device to
the up state. The message 'Missing net_device from driver' is output.
This patch fixes the issue by registering xdp_rxq info only if ethX
port is enabled (i.e. ndev pointer is not NULL).

Commit dce0919c83 ("irqchip/renesas-rzg2l: Do not set TIEN and TINT

rzg2l_irqc_irq_enable(). To address the spurious interrupt issue the
setup of TINT has been moved in rzg2l_tint_set_edge() through
rzg2l_disable_tint_and_set_tint_source(). With this, the interrupts are
not properly re-configured after a suspend-to-RAM cycle. To address
this issue and avoid spurious interrupts while resumming set the

Scrub checks the superblock version number against the known good

the version mask to compare like so:
vernum_mask = cpu_to_be16(~XFS_SB_VERSION_OKBITS |
XFS_SB_VERSION_NUMBITS |
XFS_SB_VERSION_ALIGNBIT |
XFS_SB_VERSION_DALIGNBIT |

XFS_SB_VERSION_DIRV2BIT);
This generates a sparse warning:
fs/xfs/scrub/agheader.c:168:23: warning: cast truncates bits from constant value (ffff3f8f becomes 3f8f)
This is because '~XFS_SB_VERSION_OKBITS' is considered a 32 bit
constant, even though it's value is always under 16 bits.
This is a kinda silly thing to do, because:
/*
* Supported feature bit list is just all bits in the versionnum field because
* we've used them all up and understand them all. Except, of course, for the
* shared superblock bit, which nobody knows what it does and so is unsupported.

#define XFS_SB_VERSION_ALLFBITS 0xfff0
#define XFS_SB_VERSION_SHAREDBIT 0x0200
XFS_SB_VERSION_OKBITS has a value of 0xfdff, and so
~XFS_SB_VERSION_OKBITS == XFS_SB_VERSION_SHAREDBIT. The calculated

When SPI transfer is being prepared, the spi-s3c64xx driver will call
clk_set_rate() to change the rate of SPI source clock (IPCLK). But IPCLK
is a gate (leaf) clock, so it must propagate the rate change up the
clock tree, so that corresponding MUX/DIV clocks can actually change
their values. Add CLK_SET_RATE_PARENT flag to corresponding clocks for
all USI instances in GS101 PERIC1: USI{0, 9, 10, 11, 12, 13}. This change
involves the following clocks:
PERIC1 USI*:
Clock Div range MUX Selection
-------------------------------------------------------------------
gout_peric1_peric1_top0_ipclk_* - -
dout_peric1_usi*_usi /1..16 -
mout_peric1_usi*_usi_user - {24.5 MHz, 400 MHz}
With input clock of 400 MHz this scheme provides the following IPCLK
rate range, for each USI block:
PERIC1 USI*: 1.5 MHz ... 400 MHz
Accounting for internal /4 divider in SPI blocks, and because the max
SPI frequency is limited at 50 MHz, it gives us next SPI SCK rates:
PERIC1 USI_SPI*: 384 KHz ... 49.9 MHz
Which shall be fine for the applications of the SPI bus.
Note that with this we allow the reparenting of the MUX_USIx clocks to
OSCCLK. Each instance of the USI IP has its own MUX_USI clock, thus the
reparenting of a MUX_USI clock corresponds to a single instance of the
USI IP. The datasheet mentions OSCCLK just in the low-power mode
context, but the downstream driver reparents too the MUX_USI clocks to
OSCCLK. Follow the downstream driver and do the same.

Introduce nMUX() for MUX clocks that can be reparented on clock rate
change. "nMUX" comes from "n-to-1 selector", hopefully emphasising that
the selector can change on clock rate changes. Ideally MUX/MUX_F()
should change to not have the CLK_SET_RATE_NO_REPARENT flag set by
default, and all their users to be updated to add the flag back
(like in the case of DIV and GATE). But this is a very intrusive change
and because for now only GS101 allows MUX reparenting on clock rate
change, stick with nMUX().
GS101 defines MUX clocks that are dedicated for each instance of the IP.
One example is USI IP (SPI, I2C, serial). The reparenting of these MUX
clocks will not affect other instances of the same IP or different IPs
altogether.

The Verdin family has a signal called sleep-moci which can be used to
turn off peripherals on the carrier board when the SoM goes into
suspend. So far we have hogged this signal, which means the peripherals
are always on and it is not possible to add peripherals that depend on
the sleep-moci to be on. With this change, we replace the hog with a
regulator so that peripherals can add their own regulators that use the
same gpio. Carrier boards that allow peripherals to be powered off in
suspend can disable this regulator and implement their own regulator to
control the sleep-moci.

I've had a persistent msm failure on clang, and the fix is in fixes
so just pull it back to fix that.

The first CSI2 pixel clock are supplied from IMX8MP_CLK_MEDIA_CAM1_PIX_ROOT,
the second CSI2 pixel clock are supplied from IMX8MP_CLK_MEDIA_CAM2_PIX_ROOT,
both clock are supplied from SYS_PLL2 and configured using assigned-clock DT
properties. Each CSI2 DT node configures its IMX8MP_CLK_MEDIA_CAMn_PIX_ROOT
clock. This used to be the case until likely a copy-paste error in commit
f78835d1e6 ("arm64: dts: imx8mp: reparent MEDIA_MIPI_PHY1_REF to CLK_24M")
which changed the second CSI2 node to configure IMX8MP_CLK_MEDIA_CAM1_PIX_ROOT
using its assigned-clocks property.
Fix the second CSI2 assigned-clock property back to the original correct
IMX8MP_CLK_MEDIA_CAM2_PIX_ROOT .
