Pull MMC updates from Ulf Hansson:
 "MMC core:
   - Scan the eMMC boot areas for partition table
   - Clarify purpose of mmc_can* functions by renaming them to mmc_card_can*
   - Clarify helpers for host capabilities by renaming them to mmc_host_can*
   - Add support for graceful host removal for SD and eMMC
   - Further avoid re-storing power to the eMMC before a shutdown
   - Add quirk to disable DDR50 tuning and use it for some Swissbit SD-cards

  MMC host:
   - mtk-sd: Add support for Dimensity 1200 MT6893
   - mtk-sd: Fix condition to enable single burst type
   - mtk-sd: Optimize several code-paths by aggregating register-writes
   - renesas_sdhi: Add support for the Renesas RZ/V2N variant
   - sdhci-msm: Add support for the SM7150 variant
   - sdhci-esdhc-imx: Re-factor the system PM logic
   - sdhci-esdhc-imx: Lots of improvements around the tuning support
   - sdhci-of-arasan: Add support for the Renesas RZ/N1D variant
   - sdhci-of-dwcmhsc: Add Sophgo SG2044 support
   - sdhci-of-esdhc: Add support for the LS1021a variant
   - sdhci-of-k1: Add new driver to support for SpacemiT K1 controller
   - sdhci-pic32: Convert microchip,sdhci-pic32 DT doc to json schema
   - wmt-sdmmc: Convert DT doc to json schema"

+
+description:
+  The Microchip PIC32 family of microcontrollers (MCUs) includes models with
+  Secure Digital Host Controller Interface (SDHCI) controllers, allowing them
+  to interface with Secure Digital (SD) cards. This interface is used for reading,
+  writing, and managing data on SD cards, enabling storage and data transfer
+  capabilities in embedded systems.

-* Wondermedia WM8505/WM8650 SD/MMC Host Controller
-
-This file documents differences between the core properties described
-by mmc.txt and the properties used by the wmt-sdmmc driver.
-
-Required properties:
-- compatible: Should be "wm,wm8505-sdhc".
-- interrupts: Two interrupts are required - regular irq and dma irq.
-
-Optional properties:
-- sdon-inverted: SD_ON bit is inverted on the controller
-
-Examples:
-
-sdhc@d800a000 {
-	compatible = "wm,wm8505-sdhc";
-	reg = <0xd800a000 0x1000>;
-	interrupts = <20 21>;
-	clocks = <&sdhc>;
-	bus-width = <4>;
-	sdon-inverted;
-};
