mmc: sdhci: Use CONFIG_IS_ENABLED for MMC_IO_VOLTAGE

2026-07-12T08:18:32Z

Use CONFIG_IS_ENABLED() instead of IS_ENABLED() when checking the MMC_IO_VOLTAGE symbol so the Kconfig option is evaluated correctly for xPL builds. Signed-off-by: Jonas Karlman Reviewed-by: Peng Fan Signed-off-by: Peng Fan

mmc: sdhci: Start status timeout after command issue

2026-05-15T03:44:58Z

The status polling timeout in sdhci_send_command() should measure the time spent waiting for the command interrupt after the command has been issued. Do not initialize the timer at function entry, since the command inhibit wait and setup path can consume time before SDHCI_COMMAND is written. Start the timer immediately after issuing the command instead. Signed-off-by: Tanmay Kathpalia Reviewed-by: Peng Fan Signed-off-by: Peng Fan

mmc: am654_sdhci: Add am654_sdhci_set_control_reg

2025-04-24T16:44:52Z

This patch adds am654_sdhci_set_control_reg to am654_sdhci. This is required to fix UHS_MODE_SELECT for TI K3 boards. If any of HIGH_SPEED_ENA, V1P8_SIGNAL_ENA, UHS_MODE_SELECT are set, then data will be launched on the pos-edge of the clock. Since K3 SoCs did not meet timing requirements for High Speed SDR mode at rising clock edge, none of these three should be set, therefore limit UHS_MODE_SELECT to only be set for modes above MMC_HS_52. This fixes MMC write issue on am64x evm at mode High Speed SDR. Signed-off-by: Judith Mendez Reviewed-by: Bryan Brattlof

mmc: sdhci: Fix possible Synchronous Abort using PIO mode

2025-04-11T03:49:27Z

When MMC_SDHCI_SDMA=y or MMC_SDHCI_ADMA=y and PIO mode is used dma_unmap_single() is called on an unmapped address, 0x0.

mmc: Use logging instead of printf()

2024-08-23T21:58:41Z

The code makes quite a few uses of __func__ which puts the function name into the resulting SPL image. Use the log subsystem instead, to reduce size. The CONFIG_LOGF_FUNC option can be used to enable the function name. Use lower-case hex for the status output in sdhci_transfer_data(), to match sdhci_send_command() Signed-off-by: Simon Glass Reviewed-by: Quentin Schulz

mmc: Migrate MMC_SUPPORTS_TUNING to Kconfig

The constraints on the MMC_SUPPORTS_TUNING symbol can easily be expressed in Kconfig (with the addition of SPL_MMC_SUPPORTS_TUNING). Furthermore, in order to remove from the MMC subsystem, the way this symbol is used today needs to be changed in order to continue functioning. Reviewed-by: Jaehoon Chung Signed-off-by: Tom Rini
