nvmem: meson-efuse: fix function pointer type mismatch

2024-04-03T13:11:20Z

[ Upstream commit cbd38332c140829ab752ba4e727f98be5c257f18 ] clang-16 warns about casting functions to incompatible types, as is done here to call clk_disable_unprepare: drivers/nvmem/meson-efuse.c:78:12: error: cast from 'void (*)(struct clk *)' to 'void (*)(void *)' converts to incompatible function type [-Werror,-Wcast-function-type-strict] 78 | (void(*)(void *))clk_disable_unprepare, The pattern of getting, enabling and setting a disable callback for a clock can be replaced with devm_clk_get_enabled(), which also fixes this warning.

nvmem: add explicit config option to read old syntax fixed OF cells

2023-10-21T17:19:06Z

Binding for fixed NVMEM cells defined directly as NVMEM device subnodes has been deprecated. It has been replaced by the "fixed-layout" NVMEM layout binding. New syntax is meant to be clearer and should help avoiding imprecise bindings. NVMEM subsystem already supports the new binding. It should be a good idea to limit support for old syntax to existing drivers that actually support & use it (we can't break backward compatibility!). That way we additionally encourage new bindings & drivers to ignore deprecated binding. It wasn't clear (to me) if rtc and w1 code actually uses old syntax fixed cells. I enabled them to don't risk any breakage.

firmware: meson_sm: Rework driver as a proper platform driver

2019-10-03T15:43:33Z

The secure monitor driver is currently a frankenstein driver which is registered as a platform driver but its functionality goes through a global struct accessed by the consumer drivers using exported helper functions. Try to tidy up the driver moving the firmware struct into the driver data and make the consumer drivers referencing the secure-monitor using a new property in the DT. Currently only the nvmem driver is using this API so we can fix it in the same commit. Reviewed-by: Jerome Brunet Signed-off-by: Carlo Caione Signed-off-by: Kevin Hilman

nvmem: meson-efuse: add peripheral clock
