The maple tree register cache is based on a much more modern data structure than the rbtree cache and makes optimisation choices which are probably more appropriate for modern systems than those made by the rbtree cache. Signed-off-by:

The secure update driver does a sanity-check of the image size in comparison to the size of the staging area in FLASH. Instead of hard-wiring M10BMC_STAGING_SIZE, move the staging size to the m10bmc_csr_map structure to make the size assignment more flexible. Co-developed-by:

Convert subdevices with just an interrupt and compatbile to json-schema and wire up already converted subdevices. RTC is available in all variants, so allow it unconditionally. GPADC binding for TWL603X uses two different compatibles, so specify just the compatible and do not include it. Signed-off-by:

Add support for rk816 to the existing rk808 regulator driver. The infrastructure of the driver can be re-used as is. A peculiarity for this version is, that BUCK1/BUCK2 have a (common) bit which needs to toggled after a voltage change to confirm the change. Regulator regmap takes care of that by defining a apply_bit and apply_reg for those regulators. Signed-off-by:

The AXP717a is a PMIC chip produced by X-Powers, it can be connected to an I2C or RSB bus. It's a rather complete PMIC, with many regulators, interrupts, an ADC and battery charging functionality. It also offer USB type-C CC pin handling. Describe the regmap and the MFD bits, along with the registers exposed via I2C or RSB. This covers the regulator, interrupts and power key devices for now. Advertise the device using the new compatible string. Signed-off-by:

The X-Powers AXP717 is a PMIC used on some newer Allwinner devices. Among quite some regulators it features the usual ADC/IRQ/power key parts, plus a battery charger circuit, and some newly introduced USB type-C circuitry. Like two other recent PMICs, it lacks the DC/DC converter PWM frequency control register, that rate is fixed here as well. Add the new compatible string, and add that to the list of PMICs without the PWM frequency property. Signed-off-by:

The registers to set the X-Powers AXP313 regulators are of course "CONTROL" registers, not "CONRTOL" ones. Fix the typo in the header file and in its users. No functional change. Signed-off-by:

Pull x86 fixes from Thomas Gleixner: - Ensure that the encryption mask at boot is properly propagated on 5-level page tables, otherwise the PGD entry is incorrectly set to non-encrypted, which causes system crashes during boot. - Undo the deferred 5-level page table setup as it cannot work with memory encryption enabled. - Prevent inconsistent XFD state on CPU hotplug, where the MSR is reset to the default value but the cached variable is not, so subsequent comparisons might yield the wrong result and as a consequence the result prevents updating the MSR. - Register the local APIC address only once in the MPPARSE enumeration to prevent triggering the related WARN_ONs() in the APIC and topology code. - Handle the case where no APIC is found gracefully by registering a fake APIC in the topology code. That makes all related topology functions work correctly and does not affect th...
