Maybe we should make addr and size u32s as well. Kumar requested
we take the same approach for other scm calls.

So you're saying that on arm64 we're always going to load firmware in
the lower 32 bits of memory?


Not sure what the benefit of doing this conversion higher up in the
layers are, but sure we could do it...

[Patch v3 00/10] Add RPM/SMD Support for QCOM platforms

[Andy Gross]

This patch set cleans up the documentation that is currently in place for the
SMD, SMD-RPM, and SMD-RPM regulators.  In addition, this patch set adds support
for the PM8916 found on MSM8916 platforms and the PMA8084 found on APQ8084
platforms.

  
All of the relevant DTS information is fleshed out for the regulators and their
dependencies for all of the platforms which support SMD-RPM regulators.

Changes since v2:
  - Fixed some missed review comments
  - Corrected the SMD RPM example binding indentation

Changes since v1:
  - Fixed various review comments
  - Removed MSM8974 patches as there was already an outstanding patch

Re: [PATCH 0/7] tty: serial: msm: Add DMA support and fix bit definitions

Hi,

Following patches add DMA support for UARTDM type of hardware.

Changes have been tested on UARTDM v1.3(APQ8064) and v1.4(APQ8016).

Patches from Gurav were published long ago here[1], I just addressed
remaining comments and coding style issues.

Any comments are welcome.

Looks like Magic Sysrq is broken with this patches.

[PATCH v2 0/5] Qualcomm Shared Memory State Machines

[Bjorn Andersson]

This series implements the two different mechanisms for propagating single bit
state information, used on the various Qualcomm platforms.

The system was traditionally used by the modem and application processor to
convey information about boot progress, power states, error handling and so on.
This was implemented as SMSM, with status bits representing a single local
state.

As the complexity of the SoC grew the state bits array grew and the need for
targeting specific state information at specific remote processors appeared.
SMP2P solves this by having separate shared memory regions per processor-pair.

This state information is e.g. used to convey progress and status of remote
firmware loading. Individual bits maps to various stages of the boot and error
states.

Changed since v1:
- The series moved away from representing outgoing bits as gpios
