Meson GX SoCs however use some magic bits to prevent simultaneous (=
conflicting, because only consumer should use the FIFO buffer with the
ADC results) usage by the Linux kernel and the bootloader (the BL30
bootloader uses the SAR ADC to read the CPU temperature).
This patch changes guards all BL30 functionality so it is skipped on
SoCs which don't have it. Since the hardware itself doesn't know whether
BL30 is available the internal meson_sar_adc_data is extended so this
information can be provided per of_device_id.data inside the driver.
Additionally the clocks "adc_clk" and "adc_sel" are not provided by the
clock-controller itself. "adc_sel" is not available at all. "adc_clk"
is provided by the SAR ADC IP block itself on Meson8b (and earlier).
This is already supported by the meson_saradc driver.
Finally this introduces new of_device_ids for the Meson8 and Meson8b
SoCs so the driver can be wired up in the corresponding DT.

The sysfs attribute in_proximity_sampling_frequency_available currently

correspond to the sleep values 800 400 200 100 75 50 12.5 0 (all in ms).
When passing in a sampling frequency of 3, it actually uses a sleep
time of 200ms instead of the expected 400ms value. This patch changes
the value shown by this sysfs attribute to use fixed-point numbers so
that the correct sampling frequency is shown to the user. This patch
also changes the code that updates the proximity sampling frequency to
only allow values that are shown in the _available sysfs attribute.
The original code showed the value 83 that corresponds to the sleep
time 12 ms. The data sheet actually lists 12.5 ms as the sleep time,
so the proximity frequency was updated to 80.

ion_handle was introduced as an abstraction to represent a reference to
a buffer via an ion_client. As frameworks outside of Ion evolved, the dmabuf
emerged as the preferred standard for use in the kernel. This has made
the ion_handle an unnecessary abstraction and prone to race
conditions. ion_client is also now only used internally. We have enough
mechanisms for race conditions and leaks already so just drop ion_handle
and ion_client. This also includes ripping out most of the debugfs
infrastructure since much of that was tied to clients and handles.
The debugfs infrastructure was prone to give confusing data (orphaned
allocations) so it can be replaced with something better if people

The current model of Ion heap registration is based on the outdated
model of board files. The replacement for board files (devicetree)
isn't a good replacement for what Ion wants to do. In actuality, Ion
wants to show what memory is available in the system for something else
to figure out what to use. Switch to a model where Ion creates its
device unconditionally and heaps are registed as available regions.
Currently, only system and CMA heaps are converted over to the new
model. Carveout and chunk heaps can be converted over when someone wants
to figure out how.

When CMA was first introduced, its primary use was for DMA allocation
and the only way to get CMA memory was to call dma_alloc_coherent. This
put Ion in an awkward position since there was no device structure
readily available and setting one up messed up the coherency model.
These days, CMA can be allocated directly from the APIs. Switch to using
this model to avoid needing a dummy device. This also mitigates some of
the caching problems (e.g. dma_alloc_coherent only returning uncached
memory).
