When flush_cache() is called during boot on our ~7M kernel image, the hundreds of thousands of WATCHDOG_RESET calls end up adding significantly to boottime. Flushing a single cache line doesn't take many microseconds, so doing these calls for every cache line is complete overkill. The generic watchdog_reset() provided by wdt-uclass.c actually contains some rate-limiting logic that should in theory mitigate this, but alas, that rate-limiting must be disabled on powerpc because of its get_timer() implementation - get_timer() works just fine until interrupts are disabled, but it just so happens that the "big" flush_cache() call happens in the part of bootm where interrupts are indeed disabled. [1] [2] [3] I have checked with objdump that the generated code doesn't change when this option is left at its default value of 0: gcc is smart enough to see that the ">=" comparison is tautologically true, hence all assignments to "flushed" are eliminated as dead stores. On our board, setting the option to something like 65536 ends up reducing total boottime by about 0.8 seconds.

CONFIG_5xx hasn't existed since commit 50258977 (powerpc, 5xx: remove support for 5xx). Remove this last mention of it. Reviewed-by:

Having WATCHDOG_RESET() called automatically from the timer interrupt runs counter to the idea of a watchdog device - if the board runs into an infinite loops with interrupts still enabled, the watchdog will never fire. When using CONFIG_(SPL_)WDT, the watchdog_reset function is a lot more complicated than just poking a few SOC-specific registers - it involves accessing all kinds of global data, and if the interrupt happens at the wrong time (say, in the middle of an WATCHDOG_RESET() call from ordinary code), that can end up corrupting said global data. Allow the board to opt out of calling WATCHDOG_RESET() from the timer interrupt handler by setting CONFIG_SYS_WATCHDOG_FREQ to 0 - as that setting is currently nonsensical (it would be compile-time divide-by-zero), it cannot affect any existing boards. Add documentation for both the existing and extended meaning of CONFIG_SYS_WATCHDOG_FREQ. Signed-off-by: -
The code, which is likely copied from arch/powerpc/lib/interrupts.c, lacks a fallback definition of CONFIG_SYS_WATCHDOG_FREQ and refers to a non-existing timestamp variable - obviously priv->timestamp is meant. Signed-off-by: -
Some boards don't work with the rate-limiting done in the generic watchdog_reset() provided by wdt-uclass. For example, on powerpc, get_timer() ceases working during bootm since interrupts are disabled before the kernel image gets decompressed, and when the decompression takes longer than the watchdog device allows (or enough of the budget that the kernel doesn't get far enough to assume responsibility for petting the watchdog), the result is a non-booting board. As a somewhat hacky workaround (because DT is supposed to describe hardware), allow specifying hw_margin_ms=0 in device tree to effectively disable the ratelimiting and actually ping the watchdog every time watchdog_reset() is called. For that to work, the "has enough time passed" check just needs to be tweaked a little to allow the now==next_reset case as well. Suggested-by:

Import updated devicetree files from the Linux v5.12 release. Besides some node and audio port renames this changes the PHY modes to either rgmii-id or rgmii-txid. From the board files the Pinephone sees a lot of updates. This also adds the long missing USB PHY property for controller 0, which allows the U-Boot PHY driver to eventually use port 0 in host mode (pending another U-Boot patch). Signed-off-by:

Commit eb5a2b67 ("net: sun8i-emac: Determine pinmux based on SoC, not EMAC type") switched the pinmux setup over to look at CONFIG_MACH_SUN* symbols, to find the appropriate mux value. Unfortunately this patch missed to check for the H5, which is pin-compatible to the H3, but uses a different Kconfig symbol (because it has ARMv8 vs. ARMv7 cores). Replace the pure SUN8I_H3 symbol with the joint SUNXI_H3_H5 one, which is there to cover the peripherals common to both SoCs. Also explicitly list each supported SoC, and have an error message in the fallback case, to avoid those problems in the future. This fixes Ethernet support on all H5 boards. Signed-off-by:

There is no real need to read source_id at probe time. It also doesn't make sense to store it in driver private data since it's already stored in class platform data. While this looks like cleanup (and it is), it's also important for DE2 driver rework because this info will be filled later (after probe is already executed). Signed-off-by:

It turns out that there are two ways how hot plug detection can be done. One is standard way for DW HDMI controller - checking bit 2 in 0x3004 register. Another way is applicable only to Allwinner custom PHY - by checking bit 19 in register 0x10038. Both methods are equally good as far as we know. Use standard method in order to reduce amount of custom code. Reviewed-by:
