Pull ARM Devicetree updates from Olof Johansson:
"We continue to see a lot of new material. I've highlighted some of it
below, but there's been more beyond that as well.
One of the sweeping changes is that many boards have seen their ARM
Mali GPU devices added to device trees, since the DRM drivers have now
been merged.
So, with the caveat that I have surely missed several great
contributions, here's a collection of the material this time around:
New SoCs:
- Mediatek mt8183 (4x Cortex-A73 + 4x Cortex-A53)
- TI J721E (2x Cortex-A72 + 3x Cortex-R5F + 3 DSPs + MMA)
- Amlogic G12B (4x Cortex-A73 + 2x Cortex-A53)
New Boards / platforms:
- Aspeed BMC support for a number of new server platforms
- Kontron SMARC SoM (several i.MX6 versions)
- Novtech's Meerkat96 (i.MX7)
- ST Micro Avenger96 board
- Hardkernel ODROID-N2 (Amlogic G12B)
- Purism Librem5 devkit (i.MX8MQ)
- Google Cheza (Qualcomm SDM845)
- Qualcomm Dragonboard 845c (Qualcomm SDM845)
- Hugsun X99 TV Box (Rockchip RK3399)
- Khadas Edge/Edge-V/Captain (Rockchip RK3399)
Updated / expanded boards and platforms:
- Renesas r7s9210 has a lot of new peripherals added
- Fixes and polish for Rockchip-based Chromebooks
- Amlogic G12A has a lot of peripherals added
- Nvidia Jetson Nano sees various fixes and improvements, and is now
at feature parity with TX1"

Add the canvas module to Meson8 because it's required for the VPU
(video output) and video decoders.
The canvas module is located inside thie "DMC bus" (where also some of
the memory controller registers are located). The "DMC bus" itself is
part of the so-called "MMC bus".
Amlogic's vendor kernel has an explicit #define for the "DMC" register
range on Meson8m2 while there's no such #define for Meson8. However, the
canvas and memory controller registers on Meson8 are all expressed as
"0x6000 + actual offset", while Meson8m2 uses "DMC + actual offset".
Thus it's safe to assume that the DMC bus exists on both SoCs even
though the registers inside are slightly different.

The interrupts in Amlogic's vendor kernel sources are all contiguous.
There are two typos leading to pp2 and pp4 as well as ppmmu2 and ppmmu4
incorrectly sharing the same interrupt line.
Fix this by using interrupt 170 for pp2 and 171 for ppmmu2.
Also drop the undocumented "switch-delay" which is a left-over from my
experiments with an early lima kernel driver when it was still
out-of-tree and required this property on Amlogic SoCs.

The 32-bit Meson SoCs have an RTC block in the AO (always on) area. The
RTC requires an external 32.768 kHz oscillator to work properly. Whether
or not this crystal exists depends on the board, so it has to be added
for each board.dts (instead of adding it somewhere in a generic .dtsi).

The SAR ADC can measure the chip temperature of the SoC. This only
works if the chip is calibrated and if the calibration data is written
to the correct registers. The calibration data is stored in the upper
two bytes of eFuse offset 0x1f4.
This adds the eFuse cell for the temperature calibration data and
passes it to the SAR ADC. We also need to pass the HHI sysctrl node to
the SAR ADC because the 4th TSC (temperature sensor calibration
coefficient) bit is stored in the HHI region (unlike bits [3:0] which
are stored directly inside the SAR ADC's register area).
On boards that have the SAR ADC enabled channel 8 can be used to
measure the chip temperature.

- temperature sensor calibration data (on Meson8b and Meson8m2 only)
- HDMI controller

Add the Mali-450 GPU and it's OPP table for the Meson8 and Meson8m2 (the
latter inherits meson8.dtsi).
These SoCs have a Mali-450 GPU with six pixel processors. The OPP table
is taken from the 3.10 vendor kernel which uses the following table:
FCLK_DEV7 | 1, /* 182.1 Mhz */
FCLK_DEV4 | 1, /* 318.7 Mhz */
FCLK_DEV3 | 1, /* 425 Mhz */
FCLK_DEV5 | 0, /* 510 Mhz */
FCLK_DEV4 | 0, /* 637.5 Mhz */
This describes the mux (FCLK_DEVx) and a 0-based divider in the clock
controller. "FCLK" is "fixed_pll" which is running at 2550MHz.
The "turbo" setting is described by "turbo_clock = 4" where 4 is the
index of the table above.

The values are taken from Amlogic's 3.10 kernel sources. Their sources
have a "meson8m2_n200_2G.dtd" which defines a different voltage table:
- 0.86V for 96MHz
- (values in between omitted)
- 1.14V for 1.992GHz
The reason for this is simply the hardware design because the voltage
regulator on this board is has a minimum output of 0.86V and a maximum
output of 1.14V. The recommended settings are added with this patch
instead of using the values that are only valid for one board.

The Meson8 and Meson8m2 SoCs are using four Cortex-A9 cores. These come
with an ARM global timer.
This adds the Cortex-A9 global timer but keeps it disabled for now. The
timer is clocked by the "PERIPH" clock whose rate can change during
runtime (when changing the frequency of the CPU clock). Unfortunately
the arm_global_timer driver does not handle changes to the clock rate

On Amlogic chipsets, the bias set through pinconf applies to the pad
itself, not only the GPIO function. This means that even when we change
the function of the pad from GPIO to anything else, the bias previously
set still applies.
As we have seen with the eMMC, depending on the bias type and the function,
it may trigger problems.
The underlying issue is that we inherit whatever was left by previous user
of the pad (pinconf, u-boot or the ROM code). As a consequence, the actual
setup we will get is undefined.
There is nothing mentioned in the documentation about pad bias and pinmux
function, however leaving it undefined is not an option.
This change consistently disable the pad bias for every pinmux functions.
It seems to work well, we can only assume that the necessary bias (if any)
is already provided by the pin function itself.

The clock controller registers are not 0x460 wide because the reset
controller starts at CBUS 0x4404. This currently overlaps with the
clock controller (which is at CBUS 0x4000).
There is no public documentation available on the actual size of the
clock controller's register area (also called "HHI"). However, in
Amlogic's GPL kernel sources the last "HHI" register is
HHI_HDMI_PHY_CNTL2 at CBUS + 0x43a8. 0x400 was chosen because that size
doesn't seem unlikely.

Meson6, Meson8 and Meson8b use a similar IP block which has access to
512 bytes of efuse data.
During SoC manufacturing some calibration settings for the CVBS
connector and the internal temperature sensor are written to this efuse.
On some boards it additionally stores for example the MAC addresses.
The efuse is enabled on Meson8 and Meson8b but kept disabled on Meson6
since we do not have a clock driver there (which is required to read

- the PMU (power management unit) which controls the power of the CPU

- a range in the SRAM specifically reserved for booting secondary CPU

There seem to be two memory regions that need to be reserved, otherwise
the system just hangs when running:
$ stress --vm-bytes $(awk '/MemFree/{printf "%d\n", $2 * 0.9;}' < /proc/meminfo)k \
--vm-keep -m 1
The first memory region is really crucial and without it the system
hangs. I could not find any references to this in Amlogic's GPL kernel
sources.
The second region is used by the "suspend firmware". The u-boot sources
(/arch/arm/cpu/aml_meson/m8/firmwareld.c) state that the suspend
firmware is located at "64M + 15M" which matches CONFIG_MESON_SUSPEND in
the Amlogic GPL kernel sources. The "suspend firmware" is responsible
for waking up the system from suspend state.
This also fixes reading the full SD card as without this the system
would simply hang (probably related to the first memory region, if some
buffer is allocated there).

This removes the dummy clk81 gate and replaces it with the actual clock
controller's CLKID_CLK81. This will also allow us to pass the real clock
IDs to all devices where the clock is controlled by clkc in the future.

This patch extends the L2 cache controller node for the Amlogic Meson8
and Meson8b SoCs with some missing parameters. These are taken from the
Amlogic GPL kernel source.

The Amlogic Meson SoCs have most of the internal peripherals organized
in busses. Use them to make the dts easier to read and to avoid
duplicated register (bus) offset definitions.
The bus information is taken from the vendor kernel:
#define IO_CBUS_PHY_BASE 0xc1100000 ///2M
#define IO_AOBUS_PHY_BASE 0xc8100000 ///1M
There are more internal busses (such as the abp bus which seems to
contain audio, HDMI and Mali registers), but since we don't have
drivers for them yet these are not added (yet).
