5d2fc13ba0 soc: amlogic: socinfo: build for specific arch
The MX driver only supports 32-bit ARM SoCs and the GX driver only
supports 64-bit SoCs.  Only build for the right architecture.

9ef7a79206 soc: amlogic: fix compile failure with MESON_SECURE_PM_DOMAINS & !MESON_SM
When MESON_SECURE_PM_DOMAINS & !MESON_SM, there will be compile failure:
.../meson-secure-pwrc.o: In function `meson_secure_pwrc_on':
.../meson-secure-pwrc.c:76: undefined reference to `meson_sm_call'

Fix this by adding depends on MESON_SM for MESON_SECURE_PM_DOMAINS.

b3dde5013e soc: amlogic: Add support for Secure power domains controller
Add support for the Amlogic Secure Power controller. In A1/C1 series, power
control registers are in secure domain, and should be accessed by smc.

2b45ebef39 soc: amlogic: Add Meson Clock Measure driver
The Amlogic Meson SoCs embeds a clock measurer IP to measure the internal
clock paths frequencies.
The precision is determined by stepping into the duration until the counter
overflows.
The debugfs slows a pretty summary and each clock can be measured
individually aswell.

d4983983d9 soc: amlogic: add meson-canvas driver
Amlogic SoCs have a repository of 256 canvas which they use to
describe pixel buffers.

They contain metadata like width, height, block mode, endianness [..]

Many IPs within those SoCs like vdec/vpu rely on those canvas to read/write
pixels.

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.
