mmc: meson-mx-sdio: Ignore disabled "mmc-slot" child-nodes

2025-11-18T15:21:36Z

The meson-mx-sdio (and mmc core) only support one MMC/SD/SDIO slot (device) per host. Thus having multiple mmc-slot nodes (one for the up to three supported slots with one device each on the meson-mx-sdio hardware) can be problematic. Allow specifying all slots (with their respective device) connected to the meson-mx-sdio hardware in device-tree, while making sure that only the enabled one(s) are actually considered by the driver.

mmc: meson-mx-sdio: Fix indentation in meson_mx_mmc_irq_thread()

mmc: meson-mx-sdio: Use dev_err_probe() where appropriate

mmc: meson-mx-sdio: Refactor internal clock initialization

2025-11-18T15:21:35Z

Use modern common clock framework helpers for simplifying the clock controller management: - switch to struct clk_hw for internal clocks and only get the "cfg_div_clk" (which has to be managed at runtime) as struct clk using devm_clk_hw_get_clk() which is then the only clock used by struct meson_mx_mmc_host. - use CLK_HW_INIT_FW_NAME and CLK_HW_INIT_HW helper macros for simpler init data initialization - keep the clock controller memory allocation separate to prevent a potential use-after-free because struct meson_mx_mmc_host_clkc is free'd before controller_dev Signed-off-by: Martin Blumenstingl Reviewed-by: Neil Armstrong Signed-off-by: Ulf Hansson

mmc: meson-mx-sdio: Use devm_clk_get_enabled()

mmc: meson-mx-sdio: Switch to regmap for register access

2025-11-18T15:21:35Z

Switch the driver over to use regmap to access the registers. This makes it consistent with the other Amlogic MMC drivers. No functional changes intended. Signed-off-by: Martin Blumenstingl Reviewed-by: Neil Armstrong Signed-off-by: Ulf Hansson

treewide, timers: Rename from_timer() to timer_container_of()

treewide: Switch/rename to timer_delete[_sync]()

timer_delete[_sync]() replaces del_timer[_sync](). Convert the whole tree over and remove the historical wrapper inlines. Conversion was done with coccinelle plus manual fixups where necessary. Signed-off-by: Thomas Gleixner Signed-off-by: Ingo Molnar

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.
