Hi Ondrej
What do you mean by a dummy supply?
state_test and smm_test are failing on older processors that do not
have xcr0. This is because on those processor KVM does provide
support for KVM_GET/SET_XSAVE (to avoid having to rely on the older
KVM_GET/SET_FPU) but not for KVM_GET/SET_XCRS.

For this hardware, completion is an interrupt, which has a lot of
jitter on it. But this hardware is odd, in that it uses an
interrupt. Every other MDIO bus controller uses polled IO, with an
mdelay(10) or similar between each poll.

RTC on H6 is mostly the same as on H5 and H3. It has slight differences

Some differences are already stated in the comments in existing code.
One other difference is that H6 has extra bit in LOSC_CTRL_REG, called

RTC on H6 is similar to the one on H5 SoC, but incompatible in small

Hello,
Even though this patch is a V4, I'm including more people in this review
cycle because I found that there was previous patch[1] that was discussed.
Thanks,

drivers/amba: add reset control to amba bus probe
The primecell controller on some SoCs, i.e. SoCFPGA, is held in reset by
default. Until recently, the DMA controller was brought out of reset by the
bootloader(i.e. U-Boot). But a recent change in U-Boot, the peripherals
that are not used are held in reset and are left to Linux to bring them
out
Some devices might have multiple interconnects with different DMA
addressing limitations. This function provides the higher physical
address accessible by all peripherals on the SoC. If such limitation
doesn't exist it'll return the maximum physical address of the 32 bit
addressable area.
Some devices might have weird DMA addressing limitations that only apply
to a subset of the available peripherals. For example the Raspberry Pi 4
has two interconnects, one able to address the whole lower 4G memory
area and another one limited to the lower 1G.
Being an uncommon situation we

By the time we call zones_sizes_init() arm64_dma_phys_limit already
contains the result of max_zone_dma_phys(). We use the variable instead
of calling the function directly to save some precious cpu time.

This is already supported by the driver, but is missing from the
bindings.

We'll be adding further optional regulators, and this makes it clearer
what the regulator is for.

Orange Pi 3 has two regulators that power the Realtek RTL8211E
PHY. According to the datasheet, both regulators need to be enabled
at the same time, or that "phy-io" should be enabled slightly earlier
than "phy" regulator.
RTL8211E/RTL8211EG datasheet says:

Some PHYs require separate power supply for I/O pins in some modes
of operation. Add phy-io-supply property, to allow enabling this
power supply.

Use devm_regulator_get instead of devm_regulator_get_optional and rely
on dummy supply. This avoids NULL checks before regulator_enable/disable
calls.
This path also improves error reporting, because we now report both

This uses the group validation code in the kernel.

Hi folks,
I have some doubts regarding the usage of eventfd and I'm seeking for some
advice/suggestions. I want to use eventfd in a producer-consumer manner
(EFD_SEMAPHORE) between a process's userspace and a kernel module.
The desired behaviour: periodically, a userspace thread writes to the

The race condition in the mptctl driver I'm wishing to have
confirmed is evidenced by the pair of call chains:
compat_mpctl_ioctl -> compat_mpt_command -> mptctl_do_mpt_command which
calls mpt_get_msg_frame(mptctl_id, ioc)
and
__mptctl_ioctl -> mpt_fw_download ->

The new Amlogic SM1 SoC Family is a derivative of the Amlogic G12A
SoC Family, with the following changes :
- Cortex-A55 cores instead of A53
- more power domains, including USB & PCIe
- a neural network co-processor (NNA)
- a CSI input and image processor
- some changes in the audio complex, thus
Add the compatible for the Amlogic SM1 Based SEI610 board.
