soc: qcom: cmd-db: Stop memcpy()ing in cmd_db_read_aux_data()

2018-11-14T18:06:24+00:00

Let's change the function signature to return the pointer to memory or
an error pointer on failure, and take an argument that lets us return
the size of the aux data read. This way we can remove the
cmd_db_read_aux_data_len() API entirely and also get rid of the memcpy
operation from cmd_db to the caller. Updating the only user of this code
shows that making this change allows us to remove a function and put the
lookup where the user is.

soc: qcom: cmd-db: Remove memcpy()ing from cmd_db_get_header()

2018-11-14T18:05:50+00:00

The cmd_db_get_header() function is a static local function that doesn't
need to copy anything from one place to another. Instead, it can just
point into the region by returning pointers to what we're looking for.
If we do that, we should mark what we're returning as const so that code
can't modify cmd-db without an obvious cast.

soc: qcom: Drop help text for QCOM_QMI_HELPERS

2018-11-14T18:03:36+00:00

The help text is visible in menuconfig, however QCOM_QMI_HELPERS is a
hidden kconfig, so it is not selectable in menuconfig.

Remove the help text so that it is more clear that this is intentionally
a hidden kconfig.

Txn IDs created up to INT_MAX cause overflow while storing
the IDs in u16 type supported by QMI header.

Limit the txn IDs max value to U16_MAX to avoid overflow.

soc: qcom: llcc-slice: Add error checks for API functions

2018-11-14T17:59:03+00:00

llcc_slice_getd can return a ERR_PTR code on failure. Add a IS_ERR_OR_NULL
check to subsequent API calls that use struct llcc_slice_desc to guard
against faults and to let the leaf drivers get away with safely using a
ERR_PTR() encoded "pointer" in the aftermath of a llcc_slice_getd error.

soc: qcom/llcc: add MODULE_LICENSE tag

2018-11-14T17:56:36+00:00

The lack of a MODULE_LICENSE tag prevents building the llcc driver
as a loadable module:

FATAL: modpost: GPL-incompatible module llcc-slice.ko uses GPL-only symbol 'ktime_get'

This adds the appropriate license and description tags.

soc: qcom: Add irq clear handling during SE init

2018-11-14T17:51:50+00:00

when the kernel inits a SE, its quite possible we have pending interrupts
from bootloaders which did not handle/clear them. So do this in kernel at
the SE init, to avoid some of it causing bad behavior, while at it also
club all the register writes needed to clear the se irqs into a function
to avoid repeating it over.

Merge tag 'armsoc-drivers' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc

2018-10-29T22:16:01+00:00

Pull ARM SoC driver updates from Arnd Bergmann:
 "The most noteworthy SoC driver changes this time include:

   - The TEE subsystem gains an in-kernel interface to access the TEE
     from device drivers.

   - The reset controller subsystem gains a driver for the Qualcomm
     Snapdragon 845 Power Domain Controller.

   - The Xilinx Zynq platform now has a firmware interface for its
     platform management unit. This contains a firmware "ioctl"
     interface that was a little controversial at first, but the version
     we merged solved that by not exposing arbitrary firmware calls to
     user space.

   - The Amlogic Meson platform gains a "canvas" driver that is used for
     video processing and shared between different high-level drivers.

  The rest is more of the usual, mostly related to SoC specific power
  management support and core drivers in drivers/soc:

   - Several Renesas SoCs (RZ/G1N, RZ/G2M, R-Car V3M, RZ/A2M) gain new
     features related to power and reset control.

   - The Mediatek mt8183 and mt6765 SoC platforms gain support for their
     respective power management chips.

   - A new driver for NXP i.MX8, which need a firmware interface for
     power management.

   - The SCPI firmware interface now contains support estimating power
     usage of performance states

   - The NVIDIA Tegra "pmc" driver gains a few new features, in
     particular a pinctrl interface for configuring the pads.

   - Lots of small changes for Qualcomm, in particular the "smem" device
     driver.

   - Some cleanups for the TI OMAP series related to their sysc
     controller.

  Additional cleanups and bugfixes in SoC specific drivers include the
  Meson, Keystone, NXP, AT91, Sunxi, Actions, and Tegra platforms"
