  spi: stm32: add st,stm32mp25-spi compatible supporting STM32MP25 soc (2023-12-21 20:44:05 +0000)

----------------------------------------------------------------
spi: Updates for v6.8

A moderately busy release for SPI, the main core update was the merging
of support for multiple chip selects, used in some flash configurations.
There were also big overhauls for the AXI SPI Engine and PL022 drivers,
plus some new device support for ST.

There's a few patches for other trees, API updates to allow the
multiple chip select support and one of the naming modernisations
touched a controller embedded in the USB code.

 - Support for multiple chip selects.
 - A big overhaul for the AXI SPI engine driver, modernising it and
   adding a bunch of new features.
 - Modernisation of the PL022 driver, fixing some issues with submitting
   messages while in atomic context in the process.
 - Many drivers were converted to use new APIs which avoid outdated
   terminology for devices and controllers.
 - Support for ST Microelectronics STM32F7 and STM32MP25, and Renesas
   RZ/Five.

[skipped the rest]

Hi, it seems I have an issue related with this new feature.

I just booted 6.8.0-rc1 on Turris Omnia (CONFIG_SPI_ORION=y,
device tree: arch/arm/boot/dts/marvell/armada-385-turris-omnia.dts)

and got the following error:

[    0.090231] spi_master spi0: No. of CS is more than max. no. of supported CS
[    0.097358] spi_master spi0: Failed to create SPI device for /soc/spi@10600/flash@0

End result: the three MTD partitions I used to have on the SPI-NOR are gone.

***

For reference, here's the output of 6.7.0 (configs as identical as they can be):

[    0.087965] spi-nor spi0.0: s25fl164k (8192 Kbytes)
[    0.183729] Freeing initrd memory: 4676K
[    0.191605] 3 fixed-partitions partitions found on MTD device spi0.0
[    0.191619] Creating 3 MTD partitions on "spi0.0":

[    0.191982] 0x0000000f0000-0x000000100000 : "u-boot-env"


I haven't bisected this further, but maybe the error message already rings a bell.


Best regards, Klaus

Yes, this was found on another platform - there's a patch which should
address this (unless the number is more than 8) in CI:

Actualy looking at the DT it's not immediately obvious why this is
triggering - there's only one chip select in use, numbered 0 AFAICT.
Anyway, if you could test the patch I linked hopefully it does fix the
issue.

I wouldn't have an explanation either. But said patch, applied on top of 6.8.0-rc1,
seems to be a possible cure. Everything nominal again, AFAICT.

[    0.191427] 3 fixed-partitions partitions found on MTD device spi0.0

For the records, drivers/spi/spi-orion.c states:

/* Some SoCs using this driver support up to 8 chip selects.
 * It is up to the implementer to only use the chip selects
 * that are available.
 */
#define ORION_NUM_CHIPSELECTS           8

[...]

and then in orion_spi_probe():

        host->num_chipselect = ORION_NUM_CHIPSELECTS;
