Add a new compatible for your device and imply the timing from that. That way we're not extending the binding a property at a time in a poorly designed way for each new timing quirk. Rob

It should work as the datasheet specifies a minimum of 5ms is necessary. > Is powering on the device so timing > critical? > > Add a new compatible for your device and imply the timing from that. > That way we're not extending the binding a property at a time in a > poorly designed way for each new timing quirk. OK, will do it in v2. Thank you for your review, Claudiu Beznea > > Rob >
Hi, This series adds support for selecting the delay b/w reset and power lines on pwrseq-sd8787. With this the driver could also be used by other devices (e.g. WILC1000/WILC3000 which needs a delay of 5ms). Along with this added the DT bindings for WILC3000 device present on SAMA5D27 WLSOM1 board. Thank you, Claudiu Beznea Claudiu Beznea (3): dt-bindings: mmc: pwrseq-sd8787: add binding for delay b/w reset and power mmc: pwrseq: sd8787: add support for specifying the delay b/w power and reset mmc: pwrseq: add wilc1000_sdio dependency for pwrseq_sd8787 Eugen Hristev (1): ARM: dts: at91: sama5d27_wlsom1: add wifi device .../bindings/mmc/mmc-pwrseq-sd8787.yaml | 4 ++ arch/arm/boot/dts/at91-sama5d27_wlsom1.dtsi | 72 +++++++++++++++++++ drivers/mmc/core/Kconfig | 2 +- drivers/mmc/core/pwrseq_sd8787.c | 11 ++- 4 files changed, 87 insertions(+), 2 deletions(-)
