Reset controller updates for v6.11, part 2
This tag adds USB VBUS regulator control for Renesas RZ/G2L SoCs,
which also touches PHY driver and device tree, and pulls in a new
regulator_hardware_enable() helper.
The Tegra BPMP reset driver can be compiled under COMPILE_TEST now.

Qualcomm driver updates for v6.11
Support for Shared Memory (shm) Bridge is added, which provides a
stricter interface for handling of buffers passed to TrustZone.
The X1Elite platform is added to uefisecapp allow list, to instantiate
the efivars implementation.
A new in-kernel implementation of the pd-mapper (or servreg) service is
introduced, to replace the userspace dependency for USB Type-C and
battery management.
Support for sharing interrupts across multiple bwmon instances is added,
and a refcount imbalance issue is corrected.
The LLCC support for recent platforms is corrected, and SA8775P support
is added.
A new interface is added to SMEM, to expose "feature codes". One example
of the usecase for this is to indicate to the GPU driver which
frequencies are available on the given device.
The interrupt consumer and provider side of SMP2P is updated to provide
more useful names in interrupt stats.
Support for using the mailbox binding and driver for outgoing IPC
interrupt in the SMSM driver is introduced.
socinfo driver learns about SDM670 and IPQ5321, as well as get some
updates to the X1E PMICs.
pmic_glink is bumped to now support managing 3 USB Type-C ports.

soc: qcom: smp2p: Use devname for interrupt descriptions
When using /proc/interrupts to collect statistics on smp2p interrupt
counts, it is hard to distinguish the different instances of smp2p from
each other. For example to debug a processor boot issue, the ready and
handover interrupts are checked for sanity to ensure the firmware
reached a specific initialization stage.
Remove "smp2p" string from the irq request so that the irq will default
to the device name. Add an .irq_print_chip() callback to print the irq
chip name as the device name. These two changes allow for a unique name
to be used in /proc/interrupts as shown below.

FF-A drivers initialization is now changed to module_init level so that
pKVM ffa proxy is all setup and running in case pKVM hypervisor needs to

One of the reason for not having this split from the beginning is the

driver attempting to match. Moving the workaround away from the FF-A

the SCM driver, let's use a separate memory pool. Set the initial size to
4K and - if we run out - add twice the current amount to the pool.

firmware: qcom: scm: smc: switch to using the SCM allocator
We need to allocate, map and pass a buffer to the trustzone if we have
more than 4 arguments for a given SCM call. Let's use the new TrustZone
allocator for that memory and shrink the code in process.
As this code lives in a different compilation unit than the rest of the
SCM code, we need to provide a helper in the form of
qcom_scm_get_tzmem_pool() that allows the SMC low-level routines to
access the SCM memory pool.

firmware: qcom: scm: enable the TZ mem allocator
Select the TrustZone memory allocator in Kconfig and create a pool of
memory shareable with the TrustZone when probing the SCM driver.
This will allow a gradual conversion of all relevant SCM calls to using
the dedicated allocator.
The policy used for the pool is "on-demand" and the initial size is 0
as - depending on the config - it's possible that no SCM calls needing
to allocate memory will be called. The sizes of possible allocations also
vary substiantially further warranting the "on-demand" approach.
Bartosz Golaszewski [Mon, 27 May 2024 12:54:52 +0000 (14:54 +0200)]
firmware: qcom: add a dedicated TrustZone buffer allocator
We have several SCM calls that require passing buffers to the TrustZone
on top of the SMC core which allocates memory for calls that require
more than 4 arguments.
Currently every user does their own thing which leads to code
duplication. Many users call dma_alloc_coherent() for every call which
is terribly unperformant (speed- and size-wise).
Provide a set of library functions for creating and managing pools of
memory which is suitable for sharing with the TrustZone, that is:
page-aligned, contiguous and non-cachable as well as provides a way of
mapping of kernel virtual addresses to physical space.
Make the allocator ready for extending with additional modes of operation
which will allow us to support the SHM bridge safety mechanism once all
users convert.

pwm: stm32: Fix calculation of prescaler
A small prescaler is beneficial, as this improves the resolution of the
duty_cycle configuration. However if the prescaler is too small, the
maximal possible period becomes considerably smaller than the requested
value.
One situation where this goes wrong is the following: With a parent
clock rate of 208877930 Hz and max_arr = 0xffff = 65535, a request for
period = 941243 ns currently results in PSC = 1. The value for ARR is
then calculated to
This value is bigger than 65535 however and so doesn't fit into the
respective register field. In this particular case the PWM was
configured for a period of 313733.4806027616 ns (with ARR = 98301 &
0xffff). Even if ARR was configured to its maximal value, only period =
627495.6861167669 ns would be achievable.
Fix the calculation accordingly and adapt the comment to match the new
algorithm.
With the calculation fixed the above case results in PSC = 2 and so an
actual period of 941229.1667195285 ns.
