mmc/sd specification requires a 1 ms delay (stable supply voltage)
after vdd was enabled and before issuing first command.
For most sdcard/soc combinations, the missing delay seems to be not a
problem because the processing time between enabling vdd and the first
command is often hundreds of microseconds or more. However, in our
specific case, some sdcards were not detected by u-boot:
* soc: NXP i.MX 93
* sdcards: SanDisk Ultra, 64GB micro SDXC 1,
MediaRange, 8GB, SDHC
* measured time between vdd and first command: approx. 784us
* symptom: both sdcards did not respond at all to first commands,
u-boot mmc subsystem ran into timeout and stops to
initialize the cards

Exynos7 (and later) HS-I2C blocks have special interrupts regarding
various data transfer states (see HSI2C_INT_I2C_TRANS_EN). Add support
for enabling and handling these interrupt bits.
Add the corresponding compatible, 'samsung,exynos7-hsi2c'. In order to
differentiate between the multiple device variants, an enum is
introduced which is used where difference in implementations exist.

The MediaTek MT8188 is a ARM64-based SoC with a dual-core Cortex-A78
cluster and a six-core Cortex-A55 cluster. It includes UART, SPI,
USB3.0 dual role, SD and MMC cards, UFS, PWM, I2C, I2S, S/PDIF, and
several LPDDR3 and LPDDR4 options.
This series adds basic support for MT8188.

In scmi_clk_probe(), in case of CLK_CCF is not enabled, parent private

Our last sync with the kernel was 5.1.
We are so out of sync now, that tracking the patches and backporting
them one by one makes little sense and it's going to take ages.
This is an attempt to sync up Makefiles to 6.1.
Unfortunately due to sheer amount of patches this is not easy to review,
but that's what we decided during a community call for the bump to 5.1,
so we are following the same guidelines here.

Change mt8365_evk_defconfig to use CONFIG_OF_UPSTREAM=y and delete the
U-Boot copy of the devicetree source files for mt8365.
The upstream devicetree is identical to the U-Boot one being removed
(other than having more nodes for devices not used by U-Boot and
upstream fixed a compatible string in &scpsys, also not affecting
U-Boot).
There was one minor glitch with upstream missing a few topckgen macro
definitions, so those are added to the clock driver directly as a
workaround.

code duplication"
Julien Stephan <[email protected]> says:
Commit 2dcf143398ad ("dm: video: Repurpose the 'displayport' uclass to 'display'")
left the display_read_edid() function unused by mistake.
This series addresses that oversight and introduces a new useful cmd.
Patch 1:
- Refactors display_read_timing() to use the existing
display_read_edid() function, eliminating redundant code.
- Marks display_read_edid() as static since it is not used outside of
the file.
Patch 2:
- Adds a new read_edid command, which can be very useful for debugging
or developing new display drivers.
- As this command uses display_read_edid(), the function is made
non-static again.

Add a new command to read EDID info from connected display.

read_edid callback from DISPLAY driver.

The logic for how to handle this video driver is slightly odd. Only in
the case of when CONFIG_VIDEO_LCD_PANEL_EDP_4_LANE_1620M_VIA_ANX9804 is
enabled do we need to have this file built, and otherwise we have a
dummy function in use. Correct the logic by only building this file when

Get rid of most globals that are spread around between TU's and place

If CONFIG_OF_PLATDATA=y , then the udevice has no valid OF node associated
with it and ofnode_valid(node) evaluates to 0. The dev_read_u32_default()
call ultimately reaches ofnode_read_u32_index() which invokes fdt_getprop()
and passes result of ofnode_to_offset(node) as an offset parameter into it.
The ofnode_to_offset(node) returns -1 for invalid node, which leads to an
fdt_getprop(..., -1, ...) invocation, which will crash sandbox with SIGSEGV
because libfdt can not handle negative node offsets without full tree check,
which U-Boot inhibits to keep size lower.
Since i2c_child_post_bind() already calls dev_has_ofnode(dev), reuse the
same call and assign i2c->speed_hz = I2C_SPEED_STANDARD_RATE in case the
device has no valid node associated with it, and do not call any of the
dev_read_*() functions for devices without valid nodes.

SPL_DM_PWM option simply doesn't exist. Moreover, drivers/pwm is only
included by drivers/Makefile for non-xPL stages so making
SPL_REGULATOR_PWM properly build for SPL/xPL is more involved than just
adding an SPL_DM_PWM option.
Reading the original commit (ddc824f89aa8 ("power: regulator: Allow PWM
regulator to be omitted from SPL."), the intent seemingly wasn't to
allow building support in XPL but rather to allow removing it which is
done by using $(PHASE_) ($(SPL_) at that time) in the Makefile. If
anyone needs that, let them figure out what they need to do without
misleading potential users of this symbol by simply removing it.
