We found one issue on BG4CT platforms with GPIO for the card detect interrupt: remove sdcard when there's read write access to the sdcard, sometimes the card remove event can't be handled for a long time, so the system still think the sdcard is still plugged in. It turns out that the sdhci_card_event() is missing in common slot gpio's card detect isr. This should be common for all sdhci platforms.
We fix this issue by providing sdhci's own isr for card-detect interrupts. In this own isr, we call sdhci_card_event() then process the change of state. patch1 is to prepare the fix in slot-gpio patch2 is the real fix Jisheng Zhang (2): mmc: slot-gpio: check cd_gpio before setting up cd_gpio_isr mmc: sdhci: provide isr for card-detect interrupts drivers/mmc/core/slot-gpio.c | 3 +++ drivers/mmc/host/sdhci.c | 12 ++++++++++++ 2 files changed, 15 insertions(+) -- 2.11.0
