Not all source files which include quirks.h make use of the all of the available fixup information. When this happens the compiler complains that some constant variables are defined by never used. We can fix this by telling the compiler that this intentional by simply marking them as __maybe_unused.

Related drivers like renesas_sdhi_internal_dmac are possible to lack dma unmaping in error cases (for example response timeout). Since tmio_mmc_finish_request() will be always called in any case, to fix the issue, add end operation into struct tmio_mmc_dma_ops and call the operation in tmio_mmc_finish_request() to call dma_ummap API by the related drivers correctly.

On qcom SD host controllers voltage switching be done after the HW is ready for it. The HW informs its readiness through power irq. The voltage switching should happen only then. Use the internal voltage switching and then control the voltage switching using power irq. IO-bus supply of eMMC would be kept always-on. So set the load for this supply to configure it in LPM when eMMC is suspend state and in HPM when eMMC is active.

In current code logic, when work in SDR12/SDR25 mode, the final clock rate is incorrect, just the legancy 400KHz, because the card->sw_caps.sd3_bus_mode do not has the flag SD_MODE_UHS_SDR12 or SD_MODE_UHS_SDR25. Besides, SDIO_SPEED_SDR12 is actually value 0, and every mode need to config the timing and clock rate, so remove the ‘if’ operator.

Commit 6b5eda36 ("sdio: put active devices into 1-bit mode during suspend") disabled 4-bit mode during system suspend. After this patch, commit 7310ece8 ("mmc: implement SD-combo (IO+mem) support") used new sdio_enable_4bit_bus() instead of sdio_enable_wide() to support SD-combo cards, also for card resume. However, no corresponding support added during suspend. That is not correct. Let's fix it.

If the card type is SD combo(MMC_TYPE_SD_COMBO) and the memory part does not support wider bus(SD_SCR_BUS_WIDTH_4), nothing will be done except return 0. However, we should check whether IO part support wider bus or not. We should use available IO ability if supported. In addition, there's a duplicated check to MMC_CAP_4_BIT_DATA since sdio_enable_wide() will include that check. And we can also save one call site to sdio_enable_wide() after this change.

The approach to allow userspace ~5s to consume the uevent, which is triggered when a new card is inserted/initialized, currently requires the mmc host to support system wakeup. This is unnecessary limiting, especially for an mmc host that relies on a GPIO IRQ for card detect. More precisely, the mmc host may not support system wakeup for its corresponding struct device, while the GPIO IRQ still could be configured as a wakeup IRQ via enable_irq_wake(). To support all various cases, let's simply drop the need for the wakeup support. Instead let's always register a wakeup source and activate it for all card detect IRQs by calling __pm_wakeup_event().
