      ARM: dts: keystone-k2l: fix broken Ethernet due to disabled OSR · 791229f1
      Murali Karicheri authored 
      Ethernet networking on K2L has been broken since v4.11-rc1. This was
caused by commit 32a34441 ("ARM: keystone: dts: fix netcp clocks
and add names"). This commit inadvertently moves on-chip static RAM
clock to the end of list of clocks provided for netcp. Since keystone
PM domain support does not have a list of recognized con_ids, only the
first clock in the list comes under runtime PM management. This means
the OSR (On-chip Static RAM) clock remains disabled and that broke
networking on K2L.

The OSR is used by QMSS on K2L as an external linking RAM. However this
is a standalone RAM that can be used for non-QMSS usage (as well as from
DSP side). So add a SRAM device node for the same and add the OSR clock
to the node.

Remove the now redundant OSR clock node from netcp.

To manage all clocks defined for netCP's use by runtime PM needs keystone
generic power domain (genpd) driver support which is under works.
Meanwhile, this patch restores K2L networking and is correct irrespective
of any future genpd work since OSR is an independent module and not part
of NetCP anyway.

      arm64: defconfig: enable some core options for 64bit Rockchip socs · 5711ea1b
      Heiko Stuebner authored 
      Enable some very core config options used on 64bit Rockchip socs.

As built-in driver enable the Rockchip spi driver as well as the
cros-ec-spi and cros-ec keyboard driver, as this may be helpful
in case an initrd does not work as expected and drops the user
into a shell. Another built-in is the fan53555 regulator driver,
as it and its register-compatible cousins Silergy syr827 and syr828
are often used on Rockchip socs as cpu-supply next to regular pmic.

The rest can be enabled as modules and contains the pcie host
controller and its phy, the sucessive approximation adc (saradc)
that gets often used for additional buttons on Rockchip boards
as well as the adc-keys Keyboard driver for these keys.

The cros-ec-pwm also can be a module, as it is normally only used to
drive display backlights as well as the Rockchip thermal controller
that allows to read the cpu and gpu temperatures and affect frequency
scaling if necessary.

      ARM: dts: bcm283x: Reserve first page for firmware · b0804ed0
      Phil Elwell authored 
      The Raspberry Pi startup stub files for multi-core BCM283X processors
make the secondary CPUs spin until the corresponding mailbox is
written. These stubs are loaded at physical address 0x00000xxx (as seen
by the ARMs), but this page will be reused by the kernel unless it is
explicitly reserved, causing the waiting cores to execute random code.

Use the /memreserve/ Device Tree directive to mark the first page as
off-limits to the kernel.

      memory: atmel-ebi: mark PM ops as __maybe_unused · 41b80bb1
      Arnd Bergmann authored 
      We get a harmless warning without CONFIG_PM:

drivers/memory/atmel-ebi.c:584:12: error: 'atmel_ebi_resume' defined but not used [-Werror=unused-function]

Marking the function as __maybe_unused does the right thing here
and drops it silently when unused.

      soc: imx: add PM dependency for IMX7_PM_DOMAINS · e23c7f7d

      The new pm domain driver causes a build failure when CONFIG_PM
is not set:

warning: (IMX7_PM_DOMAINS) selects PM_GENERIC_DOMAINS which has unmet direct dependencies (PM)
drivers/base/power/domain_governor.c: In function 'default_suspend_ok':
drivers/base/power/domain_governor.c:75:17: error: 'struct dev_pm_info' has no member named 'ignore_children'

This adds a dependency to ensure that we don't attempt to build the
driver without CONFIG_PM.

      ARM: dts: imx6sx-sdb: Remove OPP override · d8581c7c
      Leonard Crestez authored 
      The board file for imx6sx-sdb overrides cpufreq operating points to use
higher voltages. This is done because the board has a shared rail for
VDD_ARM_IN and VDD_SOC_IN and when using LDO bypass the shared voltage
needs to be a value suitable for both ARM and SOC.

This only applies to LDO bypass mode, a feature not present in upstream.
When LDOs are enabled the effect is to use higher voltages than necessary
for no good reason.

Setting these higher voltages can make some boards fail to boot with ugly
semi-random crashes reminiscent of memory corruption. These failures only
happen on board rev. C, rev. B is reported to still work.

      ARM: dts: imx53-qsrb: Pulldown PMIC IRQ pin · 2fe4bff3
      Fabio Estevam authored 
      Currently the following errors are seen:

[   14.015056] mc13xxx 0-0008: Failed to read IRQ status: -6
[   27.321093] mc13xxx 0-0008: Failed to read IRQ status: -6
[   27.411681] mc13xxx 0-0008: Failed to read IRQ status: -6
[   27.456281] mc13xxx 0-0008: Failed to read IRQ status: -6
[   30.527106] mc13xxx 0-0008: Failed to read IRQ status: -6
[   36.596900] mc13xxx 0-0008: Failed to read IRQ status: -6

Also when reading the interrupts via 'cat /proc/interrupts' the
PMIC GPIO interrupt counter does not stop increasing.

The reason for the storm of interrupts is that the PUS field of
register IOMUXC_SW_PAD_CTL_PAD_CSI0_DAT5 is currently configured as:
10 : 100k pullup

and the PMIC interrupt is being registered as IRQ_TYPE_LEVEL_HIGH type,
which is the correct type as per the MC34708 datasheet.

Use the default power on value for the IOMUX, which sets PUS field as:
00: 360k pull down

This prevents the spurious PMIC interrupts from happening.

Commit e1ffceb0 ("ARM: imx53: qsrb: fix PMIC interrupt level")
correctly described the irq type as IRQ_TYPE_LEVEL_HIGH, but
missed to update the IOMUX of the PMIC GPIO as pull down.

Fixes: e1ffceb0 ("ARM: imx53: qsrb: fix PMIC interrupt level")
