soc: imx: gpc: fix initialiser format

2019-12-04T21:33:12+00:00

[ Upstream commit 96ed1044fa98ea9e164fc1e679cad61575bf4f32 ]

Make the initialiers in imx_gpc_domains C99 format to fix the
following sparse warnings:

drivers/soc/imx/gpc.c:252:30: warning: obsolete array initializer, use C99 syntax
drivers/soc/imx/gpc.c:258:29: warning: obsolete array initializer, use C99 syntax

soc: renesas: Enable ARM_ERRATA_754322 for affected Cortex-A9

2019-10-05T13:11:51+00:00

[ Upstream commit 2eced4607a1e6f51f928ae3e521fe02be5cb7d23 ]

ARM Erratum 754322 affects Cortex-A9 revisions r2p* and r3p*.

Automatically enable support code to mitigate the erratum when compiling
a kernel for any of the affected Renesas SoCs:
  - RZ/A1: r3p0,
  - R-Mobile A1: r2p4,
  - R-Car M1A: r2p2-00rel0,
  - R-Car H1: r3p0,
  - SH-Mobile AG5: r2p2.

EMMA Mobile EV2 (r1p3) and RZ/A2 (r4p1) are not affected.

soc: renesas: rmobile-sysc: Set GENPD_FLAG_ALWAYS_ON for always-on domain

2019-10-05T13:11:51+00:00

[ Upstream commit af0bc634728c0bc6a3f66f911f227d5c6396db88 ]

Currently the R-Mobile "always-on" PM Domain is implemented by returning
-EBUSY from the generic_pm_domain.power_off() callback, and doing
nothing in the generic_pm_domain.power_on() callback.  However, this
means the PM Domain core code is not aware of the semantics of this
special domain, leading to boot warnings like the following on
SH/R-Mobile SoCs:

    sh_cmt e6130000.timer: PM domain c5 will not be powered off

Fix this by making the always-on nature of the domain explicit instead,
by setting the GENPD_FLAG_ALWAYS_ON flag.  This removes the need for the
domain to provide power control callbacks.

soc: qcom: geni: Provide parameter error checking

2019-09-06T09:08:08+00:00

When booting with ACPI, the Geni Serial Engine is not set as the I2C/SPI
parent and thus, the wrapper (parent device) is unassigned.  This causes
the kernel to crash with a null dereference error.

The move of the IXP4xx SoC drivers exposed their config options on all
platforms.

Fix this by wrapping them inside an ARCH_IXP4XX or COMPILE_TEST block.

Merge tag 'omap-for-v5.3/fixes-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into arm/fixes

Fixes for omap variants for v5.3-rc cycle

We have another fix to disable voltage switching for am57xx SDIO as
the bootrom cannot handle all the voltages after a reset that thought
I had already sent a pull request for earlier but forgot. And we also
update dra74x iodelay configuration for mmc3 to use the recommended
values.

Then I noticed we had introduced few new boot warnings with the various
recent ti-sysc changes and wanted to fix those. I also noticed we still
have too many warnings to be able to spot the real ones easily and fixed
up few of those. Sure some of the warnings have been around for a long
time and few of the fixes could have waited for the merge window, but
having more usable dmesg log level output is a valuable.

Other fixes are IO size correction for am335x UARTs that cause issues
for at least FreeBSD using the same device tree file that checks that
the child IO range is not larger than the parent has.

For omap1 ams-delta keyboard we need to fix a irq ack that broke with
all the recent gpio changes.

And there are also few static checker warning fixes for recent am335x
PM changes and ti-sysc driver and one switch fall-though update.
