Some platforms need the MUX state to be auto initialized at boot time even if there are no explicit users for the MUX. In these cases, the MUX device tree has "idle-states" property which specifies what state the MUX should be initialized to. So far we were relying on custom u-boot property "u-boot,mux-autoprobe" to autoprobe such MUXes. This patch causes the MUX to autoprobe if it has "idle-states" property in device tree. This should allow us to stop using the custom "u-boot,mux-autoprobe" property. Signed-off-by:Roger Quadros <rogerq@kernel.org>

Clock changes for v2024.04 This pull has the usual fixes and new (clock-adjacent) drivers. It also has some cleanups for the clock API; in particular removing the unused rfree callback. CI: https://source.denx.de/u-boot/custodians/u-boot-clk/-/pipelines/19486

Existing gpio-gate-clock driver acts like a simple GPIO switch without any effect on gated clock. Add actual clock actions into enable/disable ops and implement get_rate op by passing gated clock if it is enabled. Signed-off-by:

Currently, clock consumers cannot take any programmatic action based on the return code of a clock function. This is because there is no standardization, and generally no way of separating e.g. "there was a major problem setting the rate for this clock" which usually should not be recovered from, from "this clock doesn't support setting its rate" or "this clock doesn't support *this* rate" which could be absolutely fine depending on the driver. This commit aims to standardize the acceptable codes which may be returned from clock operations. In general, - ENOSYS should be returned when an operation is not supported for a particular clock. - ENOENT may be returned if the clock ID is invalid. However, it is encouraged to move any checks to request() to reduce code duplication. - EINVAL should be returned for logical errors only (such as requesting an invalid rate). Each function has had specific guidance added for when to return each error code. This is just guidance for now; most of the clock subsystem does not yet conform to this standard. However, it is expected that new clock drivers return these error codes. Additionally, this commit adds expected behavior for each of the clock operations. I believe these should be mostly straightforward and correspond to existing behavior. I remember not understanding what the expected invariants were for several clock functions, so hopefully this should help out new driver authors. In the future, some of these invariants could be checked via an optional config option. Signed-off-by:

When we call clk_get_rate(), we expect to get clock rate value as ulong. In that case we should not use log_ret() macro since it use internally an int. Otherwise we may return an invalid/truncated clock rate value. Signed-off-by:

In the non-redundant code for env_sf_save(), a failure to malloc() the temporary buffer produces the following output: Saving Environment to SPIFlash... OK This is misleading as the flash has neither been erased nor written. Fix it to return an error to the caller, so the output will be: Saving Environment to SPIFlash... Failed (-12) Note that there is another copy of env_sf_save() in the same file, for handling redundant environment, and it already has the same logic.

Use device-tree node property names for parsing nodes instead of indexing as indexing could be different between different SoCs based on number of DSS entities available on that particular SoC. Also correct the video layer naming in driver to match to actual one being used in upstream DSS device-tree node [1]. This also fixes AM62x splash screen usage using the latest upstream DSS device-tree nodes where hard-coded indexing which driver was using before this patch was not matching the correct properties in the DT node.

Devarsh Thakkar <devarsht@ti.com> says: Move video memory reservation for SPL at end of RAM so that it does not interefere with reservations for next stage so that the next stage need not have holes in between for passed regions and instead it can maintain continuity in reservations. Also catch the bloblist before starting reservations to avoid the same problem. While at it, also fill missing fields in video handoff struct before passing it to next stage. This is as per discussions at : For moving SPL framebuffer reservation at end of RAM: https://lore.kernel.org/all/CAPnjgZ3xSoe_G3yrqwuAvoiVjUfZ+YQgkOR0ZTVXGT9VK8TwJg@mail.gmail.com/ For filling missing video handoff fields : https://lore.kernel.org/all/CAPnjgZ1Hs0rNf0JDirp6YPsOQ5=QqQSP9g9qRwLoOASUV8a4cw@mail.gmail.com/

Setup video memory before page table reservation using "spl_reserve_video_from_ram_top" which ensures framebuffer memory gets reserved from the end of RAM. This is done to enable the next stage to directly skip the pre-reserved area from previous stage right from the end of RAM without having to make any gaps/holes to accommodate those regions which was the case before as previous stage reserved region not from the end of RAM.

- Some cleanups in header files: those do not affect the generated binaries at all. - The usual update of DT files from the kernel repo, mostly adding new board files this time. On the wake of this there is one defconfig to enable a new board, some H618 TV box branded as "Transpeed". - Samuel's series to support SPL FIT image loading for 32-bit SoCs as well, so far this was restricted to ARM64 boards. I refrained from automatically enabling this everywhere, instead this requires user intervention during board configuration. This allows to ship the "crust" management processor firmware on H3 boards, which enables better power saving. - One defconfig for an older H3 board. There was a close-by defconfig for a related board, but there are some differences which deserve a separate file. - Support for the EMAC driver to work with fixed-link PHYs, which allows to directly wire the MAC to a switch IC.

Now that 32-bit SoCs can load U-Boot proper (and possibly other firmware) from a FIT, people can use that by enabling CONFIG_SPL_LOAD_FIT. However SPL_FIT_IMAGE_TINY is required to stay within the 24 or 32 KiB SPL size limit on early SoCs; for consistency, enable it everywhere. Signed-off-by:

Some 32-bit SoCs can use SCP firmware to implement additional PSCI functionality, such as system suspend. In order to load this firmware from SPL, we need to generate and use a FIT instead of a legacy image. Adjust the binman FIT definition so it does not rely on TF-A BL31, as this is not used on 32-bit SoCs. Instead, after loading the firmware, U-Boot proper is executed directly. This requires to provide an entry point property for the U-Boot image node, which confuses some loaders like sunxi-fel, so protect that to only be used if we have no BL31. Signed-off-by:

Starting with H6, Allwinner removed the artificial 32 KiB SPL size limit from the boot ROM. Now SPL size is only limited by the available SRAM. This limit ranges from 152 KiB on H6 to a whopping 2052 KiB on R329. To take advantage of this additional space, we must increase SPL_MAX_SIZE. Since we do not want to unnecessarily pad SPL out to these giant sizes, we must set SPL_PAD_TO to zero. This causes no problems because binman already takes care of appending the SPL payload at the right offset. Signed-off-by:
