Add the SAR ADC to meson-gxbb.dtsi and meson-gxl.dtsi. GXBB provides a
10-bit ADC while GXL and GXM provide a 12-bit ADC.
Some boards use resistor ladder buttons connected through one of the ADC
channels. On newer devices (GXL and GXM) some boards use pull-ups/downs
to change the resistance (and thus the ADC value) on one of the ADC
channels to indicate the board revision.

All Meson GX SoCs (GXBB, GXL and GXM) have a PWM controller within the
AO domain. When one of the board's LEDs is connected to one of the AO
PWM pins then this can be used to dim that LED (when the leds-pwm driver
is used).
Add the pwm_AO_ab to allow such devices to use the leds-pwm driver.

Without such reserved memory zones, running the following stress command :

OdroidC2 GbE link breaks under heavy tx transfer. This happens even if the

The current hardware is not able to run with all cores enabled at a
cluster frequency superior at 1536MHz.
But the currently shipped u-boot for the platform still reports an OPP
table with possible DVFS frequency up to 2GHz, and will not change since
the off-tree linux tree supports limiting the OPPs with a kernel parameter.
A recent u-boot change reports the boot-time DVFS around 100MHz and
the default performance cpufreq governor sets the maximum frequency.
Previous version of u-boot reported to be already at the max OPP and
left the OPP as is.
Nevertheless, other governors like ondemand could setup the max frequency
and make the system crash.
This patch disables the DVFS clock and disables cpufreq.

have support for triggering a reset pulse for shared resets. On GXBB
however there is only one reset line for both PHYs (meaning we have a
shared reset line). With the latest changes to the reset framework and
the corresponding updates to the phy-meson8b-usb2 driver we can now pass
the reset to the second PHY as well.

All boards from the Tronsmart Vega S95 series are sharing similar MMC
based hardware.
sd_emmc_a is used to connect a Broadcom based SDIO wifi card (supported
by the brcmfmac driver). The 32.768KHz LPO clock for the wifi chip is
generated by PWM_E.
sd_emmc_b is routed to the SD-card. Unlike p20x there is no GPIO
regulator, meaning it only supports 3.3V (which seems to be hard-wired).
The eMMC chip is connected to sd_emmc_c and is implemented similar to
the meson-gxbb-p20x boards (meaning that hard-wired fixed regulators
are used).
