Subject: [PATCH v3 0/5] Armada 38x SDHCI driver improvements

Hi,

Thank you for reviewing the patches. According to your remarks and some
new ideas I prepared third patchset. I modified my HW and now I could
check operation when using all three modes of detection (polling, gpio
and dat3) - it all seems working fine. Any remarks will be wellcome.

Best regards,
Marcin

Changes:
v1 -> v2
* enable SW polling as card detection
* in resume function change condition for mbus windows reconfiguration

v2 -> v3
* remove redundant print after fail of mbus_win_regs obtaining
* add big comment on possible card detection options in armada-388-gp.dts
* reconstruct dat3-cd support
	- use dedicated flag in sdhci_pxa structure instead of checking
	  property in DT
	- instead of global SDHCI quirk add wrapper for sdhci_set_clock
	  function in order to keep internal clock enabled
	- prevent using pm_runtime in case of using dat3-cd
* improve MMC_CARD bit modification - do not check Armada 38x compatible
  string in pxav3_init_card callback, but use pxa->mbus_win_regs as a flag

Marcin Wojtas (5):
  mmc: sdhci-pxav3: enable proper resuming on Armada 38x SoC
  mmc: sdhci-pxav3: enable usage of DAT3 pin as HW card detect
  ARM: mvebu: set SW polling as SDHCI card detection on A388-GP
  mmc: sdhci: add init_card callback to sdhci
  mmc: sdhci-pxav3: enable modifying MMC_CARD bit during card
    initialization
