Drop the SDIO-only restriction so eMMC and SD platforms can use it too. Signed-off-by: Kamal Dasu Reviewed-by: Krzysztof Kozlowski --- Changes in v9: - No change. Changes in v8: - No change. Changes in v7: - Added Krzysztof's Reviewed-by. Changes in v6: - Split into a separate, minimal patch per Ulf: just extend keep-power-in-suspend's scope, with no brcmstb/firmware-specific rationale in its description. That rationale now lives in the new reset-card-at-resume property instead (patch 2/3), and the two are set together on brcmstb rather than folded into one property. - Also per Ulf (applies to v4 and v5 alike): dropped the mention of sdio_set_host_pm_flags() and how Linux's SDIO stack happens to expose this at runtime -- that's a software implementation detail, not a hardware/platform description. Changes in v5: - Added Krzysztof's Reviewed-by. Changes in v4: - Dropped no-mmc-poweroff-suspend entirely and extended keep-power-in-suspend instead, per Krzysztof: the two properties described the same "don't power off across suspend/resume" contract. Changes in v3: - Renamed from no-mmc-sleep; dropped S_A_TIMEOUT framing per Ulf. Changes in v2: - New patch, replacing v1's card-level quirk, per Ulf.
