2022-12-07mmc: renesas_sdhi: add quirk for broken register layoutWolfram Sang
Some early Gen3 SoCs have the DTRANEND1 bit at a different location than all later SoCs. Because we need the bit soon, add a quirk so we know which bit to use.

2022-12-07mmc: renesas_sdhi: improve naming of DMA structWolfram Sang
Commit 058db2868cd8 ("mmc: tmio, renesas_sdhi: move struct tmio_mmc_dma to renesas_sdhi.h") is correct. The DMA struct should be prefixed with 'renesas_sdhi' to avoid confusion about is namespace.

2022-12-07mmc: renesas_sdhi: remove accessor function for internal_dmacWolfram Sang
This accessor function does not help readability but makes it worse. Because I soon need to read from the registers as well and don't want to add another function like this, I chose to remove the existing one and use the accessor directly. I also switch from writeq to writel because no 64 bit register is actually involved.

2022-12-07mmc: sdhci-pci: Set PROBE_PREFER_ASYNCHRONOUSBrian Norris
This driver often takes on the order of 10ms to start, but in some cases as much as 190ms. It shouldn't have many cross-device dependencies to race with, nor racy access to shared state with other drivers, so this should be a relatively low risk change. We've done similarly with a variety of other MMC host drivers already. This driver was pinpointed as part of a survey of top slowest initcalls (i.e., are built in, and probing synchronously) on a lab of ChromeOS systems.

2022-12-07mmc: sdhci-esdhc-imx: reset the tuning logic before execute tuningHaibo Chen
For standard tuning method on usdhc, the previous tuning result can impact current tuning result, let current tuning can't set the correct delay cell. And from the logic, this is also reasonable for manual tuning method. So reset the tuning logic before execute tuning. To avoid compile issue, this patch also move the esdhc_reset_tuning() upper. Find this issue when support SDIO WiFi in band wakeup feature. After system resume back, will do re-tuning, but then meet data CRC error. Do not meet this issue on SD/eMMC, because we already call esdhc_reset_tuning() when config the legency ios, and SD/eMMC need to re-init when system resume back, but SDIO device don't do re-init if it has MMC_PM_KEEP_POWER pm_flags.

2022-12-07mmc: sdhci-*: Convert drivers to new sdhci_and_cqhci_reset()Brian Norris
An earlier patch ("mmc: cqhci: Provide helper for resetting both SDHCI and CQHCI") does these operations for us. I keep these as a separate patch, since the earlier patch is a prerequisite to some important bugfixes that need to be backported via linux-stable.

2022-12-07mmc: sdhci-of-arasan: Add support for dynamic configurationSai Krishna Potthuri
Add dynamic configuration support for Xilinx ZynqMP which takes care of configuring the SD secure space configuration registers using EEMI APIs, performing SD reset assert and deassert. High level sequence: - Check for the PM dynamic configuration support, if no error proceed with SD dynamic configurations(next steps) otherwise skip the dynamic configuration. - Put the SD Controller in reset. - Configure SD Fixed configurations. - Configure the SD Slot Type. - Configure the BASE_CLOCK. - Configure the 8-bit support. - Bring the SD Controller out of reset. - Wait for 1msec delay.

2022-12-07dt-bindings: mmc: mtk-sd: Set clocks based on compatibleNícolas F. R. A. Prado
The binding was describing a single clock list for all platforms, but that's not really suitable: Most platforms using at least 2 clocks (source, hclk), some of them a third "source_cg". Mt2712 requires an extra 'bus_clk' on some of its controllers, while mt8192 requires 8 clocks. Move the clock definitions inside if blocks that match on the compatibles. I used Patch from Nícolas F.

This driver is pretty simple, and it can be useful to build it (for validation purposes) without BMIPS or ARCH_BRCMSTB. It technically depends on CONFIG_OF to do anything useful at runtime, but it still works out OK for compile-testing using the !OF stubs.
