[PATCH v3 0/4] mmc: pwrseq: sd8787: add support wilc1000 devices

From: Claudiu Beznea <hidden>
Date: 2021-08-20 09:30:30

Hi,

This series adds support for WILC1000 devices on pwrseq-sd8787 driver.
WILC1000 devices needs a minimum delay of 5ms b/w reset and power lines.
Adapt the sd8787 driver for this by adding a new compatible for WILC1000
devices and specify the delay on .data field of struct of_device_id.

Thank you,
Claudiu Beznea

Changes in v3:
- fixed dt binding compilation

Changes in v2:
- changed cover letter title (it was: mmc: pwrseq: sd8787: add support
  for selectable)
- use new compatible in pwrseq-sd8787 driver instead of adding a new
  binding for specifying the delay; with this, the patch 1/1 from v1 is
  not necessary
- adapt patch 3/3 from this version with the new compatible

From: Claudiu Beznea <hidden>
Date: 2021-08-20 09:30:47

Add new compatible for wilc1000 devices and specify the delay in .data
member of struct of_device_id. WILC1000, WILC3000 devices needs a minimum
of 5ms delay b/w reset and power lines.

pwseq_sd8787 could also be used with wilc1000_sdio driver. Add
a dependency for this.

Again, that's the default so drop.

Did you run validation (make dtbs_check) on your changes because I see 
multiple problems.

Again, that's the default so drop.

Did you run validation (make dtbs_check) on your changes because I see
multiple problems.

No, I haven't. Apologies! I'll do the proper adjustments in v3.

Thank you for your review,

Hi,

This series adds support for WILC1000 devices on pwrseq-sd8787 driver.
WILC1000 devices needs a minimum delay of 5ms b/w reset and power lines.
Adapt the sd8787 driver for this by adding a new compatible for WILC1000
devices and specify the delay on .data field of struct of_device_id.

Thank you,
Claudiu Beznea

Changes in v3:
- fixed dt binding compilation

Changes in v2:
- changed cover letter title (it was: mmc: pwrseq: sd8787: add support
   for selectable)
- use new compatible in pwrseq-sd8787 driver instead of adding a new
   binding for specifying the delay; with this, the patch 1/1 from v1 is
   not necessary
- adapt patch 3/3 from this version with the new compatible

Applied patch1 -> patch3, thanks! I leave patch 4 for soc maintainers.

Perfect, we take care of patch 4 through at91 -> arm-soc trees for 5.16 
kernel timeframe.

Best regards,
   Nicolas
