mmc: sdhci-brcmstb: use correct register offset for V1 pin_sel restore

2026-03-19T15:15:09Z

commit 79ad471530e0baef0dce991816013df55e401d9c upstream. The restore path for SDIO_CFG_CORE_V1 was incorrectly using SDIO_CFG_SD_PIN_SEL (offset 0x44) instead of SDIO_CFG_V1_SD_PIN_SEL (offset 0x54), causing the wrong register to be written on resume. The save path already uses the correct V1-specific offset. This affects BCM7445 and BCM72116 platforms which use the V1 config core.

mmc: sdhci-brcmstb: use modern PM macros

2025-08-22T10:14:04Z

Use the modern PM macros for the suspend and resume functions to be automatically dropped by the compiler when CONFIG_PM or CONFIG_PM_SLEEP are disabled, without having to use #ifdef guards. This has the advantage of always compiling these functions in, independently of any Kconfig option. Thanks to that, bugs and other regressions are subsequently easier to catch.

mmc: sdhci-brcmstb: Drop the use of sdhci_pltfm_free()

2025-06-24T10:43:24Z

Since the devm_mmc_alloc_host() helper is already in use, sdhci_pltfm_free() is no longer needed.

mmc: Switch back to struct platform_driver::remove()

2024-10-14T10:29:01Z

After commit 0edb555a65d1 ("platform: Make platform_driver::remove() return void") .remove() is (again) the right callback to implement for platform drivers. Convert all platform drivers below drivers/mmc to use .remove(), with the eventual goal to drop struct platform_driver::remove_new(). As .remove() and .remove_new() have the same prototypes, conversion is done by just changing the structure member name in the driver initializer.
