2023-06-23mips: ralink: match all supported system controller compatible stringsShiji Yang
Recently, A new clock and reset controller driver has been introduced to the ralink mips target[1]. It provides proper system control and adds more SoC specific compatible strings. In order to better initialize CPUs, this patch removes the outdated "ralink,mt7620a-sysc" and add all dt-binding documented compatible strings to the system controller match table.

2023-06-23MIPS: DTS: CI20: Raise VDDCORE voltage to 1.125 voltsPaul Cercueil
Commit 08384e80a70f ("MIPS: DTS: CI20: Fix ACT8600 regulator node names") caused the VDDCORE power supply (regulated by the ACT8600's DCDC1 output) to drop from a voltage of 1.2V configured by the bootloader, to the 1.1V set in the Device Tree. According to the documentation, the VDDCORE supply should be between 0.99V and 1.21V; both values are therefore within the supported range. However, VDDCORE being 1.1V results in the CI20 being very unstable, with corrupted memory, failures to boot, or reboots at random. The reason might be succint drops of the voltage below the minimum required. Raising the minimum voltage to 1.125 volts seems to be enough to address this issue, while still keeping a relatively low core voltage which helps for power consumption and thermals.

2023-06-23hwrng: st - keep clock enabled while hwrng is registeredMartin Kaiser
The st-rng driver uses devres to register itself with the hwrng core, the driver will be unregistered from hwrng when its device goes out of scope. This happens after the driver's remove function is called. However, st-rng's clock is disabled in the remove function. There's a short timeframe where st-rng is still registered with the hwrng core although its clock is disabled. I suppose the clock must be active to access the hardware and serve requests from the hwrng core. Switch to devm_clk_get_enabled and let devres disable the clock and unregister the hwrng. This avoids the race condition.

2023-06-23crypto: sig - Add interface for sign/verifyHerbert Xu
Split out the sign/verify functionality from the existing akcipher interface. Most algorithms in akcipher either support encryption and decryption, or signing and verify. Only one supports both. As a signature algorithm may not support encryption at all, these two should be spearated. For now sig is simply a wrapper around akcipher as all algorithms remain unchanged.

Hash driver needs to check the value of irq mask register before writing as it will mask irq of other modules.

2023-06-23crypto: caam - optimize RNG sample sizeMeenakshi Aggarwal
TRNG "sample size" (the total number of entropy samples that will be taken during entropy generation) default / POR value is very conservatively set to 2500. Let's set it to 512, the same as the caam driver in U-boot (drivers/crypto/fsl_caam.c) does. This solves the issue of RNG performance dropping after a suspend/resume cycle on parts where caam loses power, since the initial U-boot setttings are lost and kernel does not restore them when resuming. Note: when changing the sample size, the self-test parameters need to be updated accordingly.
