[PATCH 0/7] Device table matching for SPI subsystem

[Anton Vorontsov]

Hi all,

This patch set implements standard device table matching mechanism
for SPI subsystem, the same device id tables as we use in I2C drivers.

I started this work because m25p80 driver misdetects non-JEDEC
chips when it is used on OpenFirmware platforms (cause we don't pass
platform_data). platform_data is overkill for m25p80 chips, the
driver only needs to know exact chip model, and that's what device
tables are for.

So the patches:

  [1/7] spi: Add support for device table matching
  [2/7] mtd: m25p80: Convert to device table matching
  [3/7] of: Remove "stm,m25p40" alias

The three patches above do real work. I tried to keep the 1/7 patch as
small as possible, and factor out the subsystem cleanups into other,
"cleanup" patches:

  [PATCH 4/7] spi: Prefix modalias with "spi:"
  [PATCH 5/7] spi: Merge probe and probe_id callbacks

These two patches I consider as cleanups, they should not introduce
any behavioural change, but they touch quite a lot of files.

  [PATCH 6/7] hwmon: adxx: Convert to device table matching
  [PATCH 7/7] hwmon: lm70: Convert to device table matching

These two are here because I couldn't stop. :-) Also cleanups.

[PATCH 1/7] spi: Add support for device table matching

[Anton Vorontsov]

With this patch spi drivers can use standard spi_driver.id_table and
MODULE_DEVICE_TABLE() mechanisms to bind against the devices. Just
like we do with I2C drivers.

This is useful when a single driver supports several variants of
devices but it is not possible to detect them in run-time (like
non-JEDEC chips probing in drivers/mtd/devices/m25p80.c), and
when platform_data usage is overkill.

This patch also makes life a lot easier on OpenFirmware platforms,
since with OF we extensively use proper device IDs in modaliases.

[lm-sensors] [PATCH 1/7] spi: Add support for device table matching

[Anton Vorontsov]

With this patch spi drivers can use standard spi_driver.id_table and
MODULE_DEVICE_TABLE() mechanisms to bind against the devices. Just
like we do with I2C drivers.

This is useful when a single driver supports several variants of
devices but it is not possible to detect them in run-time (like
non-JEDEC chips probing in drivers/mtd/devices/m25p80.c), and
when platform_data usage is overkill.

This patch also makes life a lot easier on OpenFirmware platforms,
since with OF we extensively use proper device IDs in modaliases.

how about leaving it at just probe and have either a call or a field
in the device that you can look at to see if this was a new style of
call?

how about leaving it at just probe and have either a call or a field
in the device that you can look at to see if this was a new style of
call?

There are no technical difficulties with that, but it would be
inconsitent wrt other "device table"-aware buses (i2c, pci, of).

Note that I'm getting rid of probe_id function in patch 5/7, as a
cleanup step. I want to keep "new features" and "api cleanups"
separate. That way it's easier to review the changes.

Thanks!

Btw, I guess there are few reasons why other buses pass id via
probe() call:

- You'll have to store the "id" in device struct forever, while
  in most cases you only need it during probe(), then you don't
  need it at all;

Btw, I guess there are few reasons why other buses pass id via
probe() call:

- You'll have to store the "id" in device struct forever, while
  in most cases you only need it during probe(), then you don't
  need it at all;

Hm... actually, we're doing this anyway, but in spi core.

So, doing something like spi_get_device_id() might be a good
idea.

For the record, if this is going to happen I think the
appropriate long-term solution is to have probe() take
the device_id just as it does with other busses.

Of course that involves changing *every* SPI driver...
and I'd rather not do that quite yet.

Just curious. Why you prefer another argument in the probe()
instead of calling some helper function? Most drivers don't
need the "id" argument, so why spend memory and cpu cycles
for it?

[PATCH 2/7] mtd: m25p80: Convert to device table matching

[Anton Vorontsov]

This patch converts the m25p80 driver so that now it uses .id_table
for device matching, making it properly detect devices on OpenFirmware
platforms (prior to this patch the driver misdetected non-JEDEC chips,
seeing all chips as "m25p80").

Also, now jedec_probe() only does jedec probing, nothing else. If it
is not able to detect a chip, NULL is returned and the driver fall
backs to the information specified by the platform (platform_data, or
exact ID).

[PATCH 2/7] mtd: m25p80: Convert to device table matching

[Anton Vorontsov]

This patch converts the m25p80 driver so that now it uses .id_table
for device matching, making it properly detect devices on OpenFirmware
platforms (prior to this patch the driver misdetected non-JEDEC chips,
seeing all chips as "m25p80").

Also, now jedec_probe() only does jedec probing, nothing else. If it
is not able to detect a chip, NULL is returned and the driver fall
backs to the information specified by the platform (platform_data, or
exact ID).

[PATCH 2/7] mtd: m25p80: Convert to device table matching

[Anton Vorontsov]

This patch converts the m25p80 driver so that now it uses .id_table
for device matching, making it properly detect devices on OpenFirmware
platforms (prior to this patch the driver misdetected non-JEDEC chips,
seeing all chips as "m25p80").

Also, now jedec_probe() only does jedec probing, nothing else. If it
is not able to detect a chip, NULL is returned and the driver fall
backs to the information specified by the platform (platform_data, or
exact ID).

Also, now jedec_probe() only does jedec probing, nothing else. If it
is not able to detect a chip, NULL is returned and the driver fall
backs to the information specified by the platform (platform_data, or
exact ID).

[PATCH 4/7] spi: Prefix modalias with "spi:"

[Anton Vorontsov]

This makes it consistent with other buses (platform, i2c, vio, ...).
I'm not sure why we use the prefixes, but there must be a reason.

This was easy enough to do it, and I did it.

[PATCH 4/7] spi: Prefix modalias with "spi:"

[Anton Vorontsov]

This makes it consistent with other buses (platform, i2c, vio, ...).
I'm not sure why we use the prefixes, but there must be a reason.

This was easy enough to do it, and I did it.

[PATCH 4/7] spi: Prefix modalias with "spi:"

[Anton Vorontsov]

This makes it consistent with other buses (platform, i2c, vio, ...).
I'm not sure why we use the prefixes, but there must be a reason.

This was easy enough to do it, and I did it.

[lm-sensors] [PATCH 4/7] spi: Prefix modalias with "spi:"

[Anton Vorontsov]

This makes it consistent with other buses (platform, i2c, vio, ...).
I'm not sure why we use the prefixes, but there must be a reason.

This was easy enough to do it, and I did it.

[PATCH 5/7] spi: Merge probe and probe_id callbacks

[Anton Vorontsov]

The probe_id callback was introduced for the transition period
as a "new-style" probe hook. This patch makes probe() look exactly
as probe_id(), converts drivers and removes probe_id().

[PATCH 5/7] spi: Merge probe and probe_id callbacks

[Anton Vorontsov]

The probe_id callback was introduced for the transition period
as a "new-style" probe hook. This patch makes probe() look exactly
as probe_id(), converts drivers and removes probe_id().

[PATCH 5/7] spi: Merge probe and probe_id callbacks

[Anton Vorontsov]

The probe_id callback was introduced for the transition period
as a "new-style" probe hook. This patch makes probe() look exactly
as probe_id(), converts drivers and removes probe_id().

[lm-sensors] [PATCH 5/7] spi: Merge probe and probe_id callbacks

[Anton Vorontsov]

The probe_id callback was introduced for the transition period
as a "new-style" probe hook. This patch makes probe() look exactly
as probe_id(), converts drivers and removes probe_id().

To be fair, the platform_data also supports partitioning
and labeling e.g. for cmdlinepart ... though I'd tend to
agree that most SPI flash chips are kind of small (so
they're mostly just one smallish partition).

With OF we do partitioning and labling via drivers/mtd/ofpart.c.

Though, so far there is no support for OF partitions in the m25p80
driver. I think we'd better put the OF partitions probing into
parse_mtd_partitions(), and avoid calling of_mtd_parse_partitons()
directly...

Thanks,
