From Brendan Heading:
You may be aware of the musl C-library implementation, which tries to
be strictly standards compliant, avoids non-standard extensions, etc.
Some distributions have adopted it as their standard C library, in
others (such as buildroot) it is a configuration alternative.
Vanilla lm-sensors does not compile under musl, due to the following
excerpt which appears in four different places. The code is checking
that the glibc version is greater than 2.0.
#if defined(__GLIBC__) && __GLIBC__ == 2 && __GLIBC_MINOR__ >= 0
#include <sys/io.h>
#else
#include <asm/io.h>
#endif
This fails under musl does not define __GLIBC__ (in fact, by design,
it doesn't provide any way to identify itself at all) - which causes
it to try to include <asm/io.h> rather than <sys/io.h>.
It's a long time since glibc 2.0.1 was released - 1997. Accordingly,
it seems to make little sense at this stage to try to retain
compatibility with very old libcs - so maybe it should be removed
entirely.
Sometimes the hardware expects 16-bit or 32-bit reads rather than byte
reads. Add support to isadump so that the user can ask for such reads.

back from the address port, so the value 0xff is returned, causing
a false positive with the original test. Testing explicitly for 0x80
instead of only testing that bit 7 is set, works around it.

Default to bank register 0x07 for Super-I/O chips.
Move default bank register selection to a separate function.
Move setting/restoring bank to a separate function.
Allow dumping of shorter ranges (flat address space mode).
Limit I2C-like dumps to addresses up to 0x3fff.
Print expected ranges on range errors.
This should allow us to work with the PC87360 family of chips.

Allow forcing of bank 0. Restore bank after dump.
This allows proper operation on Super-I/O chips.

Replaced sys/perm.h with sys/io.h. But then it conflicted
with asm/io.h so I changed it to only use one or the other.
Hope it works.

* i2c-isa simplified, by using the addr field in the client structure,
instead of a new field. This means we do not need `struct isa_*'
anymore
* All clients changed to reflect the new isa code. Many are much
simplified now.

Usage: isadump <ADDR-REG> <DATA-REG>
For the default LM78, this would be `isadump 0x295 0x296' (addresses may be
specified as decimal, octal or hexadecimal).
