When do system suspend/resume test, uSDHC may meet timeout during eMMC
initialization. This is caused by the uSDHC AHB_BUS and IPG_CLK being
out of sync.
ERR011232 requires that uSDHC AHB_BUS and IPG_CLK must be synchronized.
Need to ensure uSDHC AHB_BUS and IPG_CLK come form same clock source to

If the bridge is attached with the DRM_BRIDGE_ATTACH_NO_CONNECTOR flag set,
this driver won't initialize a connector and hence display mode won't be
validated in drm_connector_helper_funcs::mode_valid(). So, move the mode
validation from drm_connector_helper_funcs::mode_valid() to
drm_bridge_funcs::mode_valid(), because the mode validation is always done
for the bridge.

The Synopsys driver needs a mode fixup to support 720p60 for some bridges.
This patch add support to honor the MIPI_DSI_MODE_VIDEO_NO_HFP and
MIPI_DSI_MODE_VIDEO_NO_HBP MIPI DSI mode flags for MIPI sync events mode.
The default behavior for MIPI DSI low power mode with sync pulses is
unchanged.
Also, a timing fixup is implemented to force low power mode for the
horizontal front porch (HFP) for 720p60 with 4 lanes at 24 bit per pixel.
In this mode, the MIPI line has to be rounded up by 2 bytes. This
rounding causes timing errors and corrupts the video for 720p60. By
reducing the horizontal back porch (HBP) by 32 pixels, the Synopsys MIPI
DSI controller will use low power mode for the HFP. By using low power mode
in the HFP the DSI host controller will resynchronize the line timing to
the DPI interface.

There is a potential crash issue when disabling and re-enabling the
network port. When disabling the network port, phy_detach() calls
device_link_del() to remove the device link, but it does not clear
phydev->devlink, so phydev->devlink is not a NULL pointer. Then the
network port is re-enabled, but if phy_attach_direct() fails before
calling device_link_add(), the code jumps to the "error" label and
calls phy_detach(). Since phydev->devlink retains the old value from
the previous attach/detach cycle, device_link_del() uses the old value,
which accesses a NULL pointer and causes a crash. The simplified crash
log is as follows.
[ 24.702421] Call trace:
[ 24.704856] device_link_put_kref+0x20/0x120
[ 24.709124] device_link_del+0x30/0x48

[ 24.725140] phylink_of_phy_connect+0x1c/0x34
Therefore, phydev->devlink needs to be cleared when the device link is
deleted.

The secure enclave FW communicates on a dedicated messaging unit(MU)

It exists on specific i.MX processors. e.g. i.MX8ULP, i.MX93.
This patch adds the driver for communication interface to secure-enclave,
for exchanging messages with NXP secure enclave HW IP(s) like EdgeLock
Enclave (ELE) from Kernel-space, used by kernel management layers like

Design team says that the frequency limitation mentioned at controller
specification is just a general guideline for the IP. The maximum frequency
depends on the process technology and SoC architecture requirement of the
SoC. Specifically for i.MX95, the frequency of dspx_clk is signed off at
350MHz at UD/NM/OD mode. So 350MHz is the limit of the chip, not 300MHz.
So, change maximum FrameGen display clock frequency from 300MHz to 350MHz.
