Making register definition less generic which will potentially have less collision with other files.

2025-06-24mmc: sdhci-esdhc-imx: optimize clock loopback selection with dummy pad supportLuke Wang
For legacy platforms without dummy pad: When clock <= 100MHz: Set ESDHC_MIX_CTRL_FBCLK_SEL to 0 (external clock pad loopback) for better bus clock proximity. When clock > 100MHz: Set ESDHC_MIX_CTRL_FBCLK_SEL to 1 (internal clock loopback) to avoid signal reflection noise at high frequency. For i.MX94/95 with dummy pad support: Keep ESDHC_MIX_CTRL_FBCLK_SEL at 0 for all speed mode. Hardware automatically substitutes clock pad loopback with dummy pad loopback when available, eliminating signal reflections while preserving better bus clock proximity.

2025-06-24mmc: sdhci-esdhc-imx: refactor clock loopback selection logicLuke Wang
i.MX reference manual specifies that internal clock loopback should be used for SDR104/HS200/HS400 modes. Move ESDHC_MIX_CTRL_FBCLK_SEL configuration into the timing selection function to: 1. Explicitly set internal loopback path for SDR104/HS200/HS400 modes 2. Avoid redundant bit manipulation across multiple functions Preserve ESDHC_MIX_CTRL_FBCLK_SEL during system resume for SDIO devices with MMC_PM_KEEP_POWER and MMC_PM_WAKE_SDIO_IRQ flag, as the controller might lose register state during suspend while skipping card re-initialization.

2025-06-24mmc: sdhci-esdhc-imx: Don't change pinctrl in suspend if wakeup sourceHaibo Chen
The pinctrl sleep state may config the pin mux to certain function to save power in system suspend. Unfortunately this doesn't work if usdhc is used as a wakeup source, like waking up on SDIO irqs or card-detect irqs. In these cases, we need pin mux to be configured to usdhc function pad. The issue is found on imx93-11x11-evk board, where WiFI over SDIO with in-band irqs fails to wakeup the system, because the DATA[1] pin has been set to GPIO function. To fix the problem, don't change the pinctrl state in suspend if there is a system wakeup enabled.

2025-06-19mtk-sd: Prevent memory corruption from DMA map failureMasami Hiramatsu (Google)
If msdc_prepare_data() fails to map the DMA region, the request is not prepared for data receiving, but msdc_start_data() proceeds the DMA with previous setting. Since this will lead a memory corruption, we have to stop the request operation soon after the msdc_prepare_data() fails to prepare it.

2025-06-09mtk-sd: Fix a pagefault in dma_unmap_sg() for not prepared dataMasami Hiramatsu (Google)
When swiotlb buffer is full, the dma_map_sg() returns 0 to msdc_prepare_data(), but it does not check it and sets the MSDC_PREPARE_FLAG. swiotlb_tbl_map_single() /* prints "swiotlb buffer is full" */ <-swiotlb_map() <-dma_direct_map_page() <-dma_direct_map_sg() <-__dma_map_sg_attrs() <-dma_map_sg_attrs() <-dma_map_sg() /* returns 0 (pages mapped) */ <-msdc_prepare_data() Then, the msdc_unprepare_data() checks MSDC_PREPARE_FLAG and calls dma_unmap_sg() with unmapped pages. It causes a page fault. To fix this problem, Do not set MSDC_PREPARE_FLAG if dma_map_sg() fails because this is not prepared.

Move the BROKEN_SD_DISCARD quirk for certain SanDisk SD cards from the `mmc_blk_fixups[]` to `mmc_sd_fixups[]`. This ensures the quirk is applied earlier in the device initialization process, aligning with the reasoning in [1]. Applying the quirk sooner prevents the kernel from incorrectly enabling discard support on affected cards during initial setup.
