87f88732d2 soc: amlogic: meson-gx-pwrc-vpu: fix error on shutdown when domain is powered off
When operating the system headless headless, the domain is never
powered on, leaving the clocks disabled. The shutdown function then
tries to disable the already disabled clocks, resulting in errors.
Therefore call meson_gx_pwrc_vpu_power_off() only if domain is
powered on.
This patch fixes the described issue on my system (Odorid-C2).

3a2ad7bd31 soc: amlogic: meson-gx-pwrc-vpu: don't print error message on probe deferral
The error message may be misleading in case of probe deferral
(happens on my Odroid-C2). Therefore don't print it in this case.

044d71bc6c meson-gx-socinfo: Fix package id parsing
I've noticed the following message while booting a S905X based board:

soc soc0: Amlogic Meson GXL (S905D) Revision 21:82 (b:2) Detected

The S905D string is obviously wrong. The vendor code does:
...
        ver = (readl(assist_hw_rev) >> 8) & 0xff;
        meson_cpu_version[MESON_CPU_VERSION_LVL_MINOR] = ver;
        ver =  (readl(assist_hw_rev) >> 16) & 0xff;
        meson_cpu_version[MESON_CPU_VERSION_LVL_PACK] = ver;
...

while the current code does:
...
...

This means that the current mainline code has package id and minor
version reversed.

339cd0ea08 soc: amlogic: meson-gx-pwrc-vpu: fix power-off when powered by bootloader
In the case the VPU power domain has been powered on by the bootloader
and no driver are attached to this power domain, the genpd will power it
off after a certain amount of time, but the clocks hasn't been enabled
by the kernel itself and the power-off will trigger some faults.
This patch enable the clocks to have a coherent state for an eventual
poweroff and switches to the pm_domain_always_on_gov governor.

30f3b0678c soc: amlogic: gx pm domain: add PM and OF dependencies
The new driver introduces harmless warnings:

warning: (PM_RMOBILE && ARCH_RCAR_GEN1 && ARCH_RCAR_GEN2 && ARCH_R7S72100 && MESON_GX_PM_DOMAINS) selects PM_GENERIC_DOMAINS which has unmet direct dependencies (PM)
warning: (MESON_GX_PM_DOMAINS) selects PM_GENERIC_DOMAINS_OF which has unmet direct dependencies (PM_GENERIC_DOMAINS && OF)

This adds CONFIG_OF and CONFIG_PM dependencies to ensure it
will only be enabled in valid configurations.

The Video Processing Unit needs a specific Power Domain powering scheme

5e68c0fc8d soc: amlogic: Add Meson6/Meson8/Meson8b/Meson8m2 SoC Information driver
Amlogic SoCs have an information register which contains the SoC type
and revision information.
This patchs adds support for decoding those registers and exposing the
resulting information via the SoC bus infrastructure.
