SDIO interrupts Not reaching driver from SDHC
Hi Team,
We have one embedded platform,which runs for wifi-mode.On that board from firmware interrupts are invoking and reaching to SD host controller but Not receiving by the driver.
But when we change clock frequency to lower frequency(from 50 to 25/5MHZ)in the driver,Driver is able to receive up to 20 interrupts but behavior is same again.
Can you please suggest any thing from kernel level,so that Driver is able to get interrupts from SDHC/firmware.
One more thing is "CONFIG_MMC_CLKGATE"(MMC_CAP_CLOCK_GATING_HW) this option is not there in the .config file as this option is enabled only in 3.9–3.19, 4.0–4.3 this kernels.
Please let us know what is the equivalent macro for the above macro in the above kernels (4.4).
Is there any thing in the kernel that needs to be enabled for SDIO so that driver will receive SDIO interrupts.
Regards,
Pavani
