commit a88afa46b86ff461c89cc33fc3a45267fff053e8 upstream.
When the kernel is configured to use the Thumb-2 instruction set
"suspend-to-memory" fails to resume. Observed on a Colibri iMX6ULL
(i.MX 6ULL) and Apalis iMX6 (i.MX 6Q).
It looks like the CPU resumes unconditionally in ARM instruction mode
and then chokes on the presented Thumb-2 code it should execute.
Fix this by using the arm instruction set for all code in

The imx_soc_device_init functions tries to fetch the ocotp regmap in
order to soc serial number. If regmap fetch fails then a message is
printed but regmap_read is called anyway and the system crashes.
Failing to lookup ocotp regmap shouldn't be a fatal boot error so check
that the pointer is valid.
Only side-effect of ocotp lookup failure now is that serial number will
be reported as all-zeros which is acceptable.

the kernel doesn't start on i.MX6ULL/ULZ SoC.
Tested on next-20191205.

ffbc34bf0e ("nvmem: imx-ocotp: Implement i.MX6ULL/ULZ support") and commit
f243bc821e ("ARM: dts: imx6ull: Fix i.MX6ULL/ULZ ocotp compatible") the value
"fsl,imx6ull-ocotp" is already defined and set in device tree...
By setting "ocotp_compat" to "fsl,imx6ull-ocotp" the kernel does boot.

512a928affd5 ("ARM: imx: build v7_cpu_resume() unconditionally")
introduced an unintended linker error for i.MX6 configurations that have
ARM_CPU_SUSPEND=n which can happen if neither CONFIG_PM, CONFIG_CPU_IDLE,
nor ARM_PSCI_FW are selected.
Fix this by having v7_cpu_resume() compiled only when cpu_resume() it

ARM_ERRATA_814220 has below description:
The v7 ARM states that all cache and branch predictor maintenance
operations that do not specify an address execute, relative to
each other, in program order.
However, because of this erratum, an L2 set/way cache maintenance
operation can overtake an L1 set/way cache maintenance operation.
This ERRATA only affected the Cortex-A7 and present in r0p2, r0p3,
r0p4, r0p5.

commit 512a928affd51c2dc631401e56ad5ee5d5dd68b6 upstream.
This function is not only needed by the platform suspend code, but is also
reused as the CPU resume function when the ARM cores can be powered down
completely in deep idle, which is the case on i.MX6SX and i.MX6UL(L).
Providing the static inline stub whenever CONFIG_SUSPEND is disabled means
that those platforms will hang on resume from cpuidle if suspend is disabled.
So there are two problems:
- The static inline stub masks the linker error
- The function is not available where needed
Fix both by just building the function unconditionally, when
CONFIG_SOC_IMX6 is enabled. The actual code is three instructions long,
so it's arguably ok to just leave it in for all i.MX6 kernel configurations.

During system counter frequency change, the counter will stop, it
takes several mS even up to 20mS to finish the frequency change, if
system enters STOP mode before the frequency change done, system
counter will NOT run during STOP mode, then it will case system time
inaccurate and sometimes cause below RCU stall, so system can ONLY
enter STOP mode after the system counter frequency change done by
checking the ACK of frequency change.

The GPC power domain driver add GENPD_FLAG_RPM_ALWAYS_ON to
the i.MX6QP's PU power domain flag, that means it is always ON
for runtime PM but can be OFF during suspend, so no need to
explicitly power ON/OFF PU power for i.MX6QP during suspend/resume
to avoid below dump:

Init ENET RGMII tx clock source, set GPR5[9] to select clock from
internal PLL_enet. And set phy VDDIO to 1.8V that get better signal
quality.

The management data input/output (MDIO) bus where often high-speed,
open-drain operation is required. i.MX7D TO1.0 ENET MDIO pin has no
open drain as IC ticket number: TKT252980, i.MX7D TO1.1 fix the issue.
