+Subject: [PATCH] mmc: bcmstb: Fix non-removable check in bcm2712 init
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+sdhci_brcmstb_init_2712() reads host->mmc->host_caps to decide whether
+to force card-detect for a non-removable eMMC, or to route the CD signal
+for a removable SD card. At the time this function runs from
+sdhci_bcmstb_probe(), however, host->mmc->host_caps is still zero, that
+field is only populated later by the MMC uclass, after the driver's
+probe returns. mmc_of_parse() has already filled plat->cfg.host_caps
+from the device tree by this point, so check that field instead.
+
+Without the fix, every BCM2712 SDHCI instance takes the else branch and
+writes SDIO_CFG_SD_PIN_SEL = SDIO_CFG_SD_PIN_SEL_CARD (0x02), including
+the non-removable eMMC on boards such as CM5 on Home Assistant Yellow.
+The SDIO_CFG block lies outside the SDHCI core's reset scope, so this
+value persists across SDHCI_RESET_ALL into the next stage. On the
+BCM2712, having SD_PIN_SEL set to "SD" when the Linux kernel performs
+its first set_power(MMC_POWER_UP) write racily prevents the SDHCI
+POWER_ON bit from latching (see [1] for the whole backstory) - the
+voltage bits stick but POWER_ON drops - which wedges the first CMD0 the
+full 10 s software timeout. On Home Assistant Yellow this manifested as
+a ~20 s eMMC probe delay on roughly one in two Linux boots when U-Boot
+was the previous stage. Booting directly from the Pi firmware (no U-Boot
+in between) left SD_PIN_SEL at its default and did not exhibit the race.
+
+Reading plat->cfg.host_caps lets init_2712 see the "non-removable"
+property and take the correct branch, leaving SD_PIN_SEL untouched for
+the eMMC.
