Remove dependencies on HAS_DMA where a Kconfig symbol depends on another symbol that implies HAS_DMA, and, optionally, on "|| COMPILE_TEST". In most cases this other symbol is an architecture or platform specific symbol, or PCI. Generic symbols and drivers without platform dependencies keep their dependencies on HAS_DMA, to prevent compiling subsystems or drivers that cannot work anyway. This simplifies the dependencies, and allows to improve compile-testing. Signed-off-by:

It's better to use the __func__ macro instead of open-code the function name. This fixes the following checkpatch warning: WARNING: Prefer using '"%s...", __func__' to using 'x', this function's name, in a string Signed-off-by:

Hiding memset behind a macro isn't the best, because it relies on that the parameter is not a pointer. Luckily all user has been removed, so we can remove BITSET_ZERO too. Signed-off-by:

pi433_write requires locking due to multiple writers. After acquiring the lock check if enough free space is available in the kfifo to write the whole message. This check should prevent partial writes to tx_fifo so kfifo_reset is not needed anymore. pi433_tx_thread is the only reader so it does not require locking after kfifo_reset is removed.

The current default transfer is to use DMA or not depending on the size of the data. The upstream driver mtk-sd uses DMA all times, change the standard mode here to DMA for testing, if there are any performance problems with DMA for small data sizes. If not, the option for transfer mode should be removed in the future, Signed-off-by:

The msdc_init_gpd_bd function is currently hard to read, because of old, commented out code and a while loop, where a for loop is much easier to read. Refactor it to make the code more readable. Signed-off-by:

The flags of msdc_dma are set to a constant value, so block and dword padding are disabled and checksum is enabled. By removing the field the code is easier to read and the difference to the mtk-sd driver is smaller. Signed-off-by:

Currently the msdc_dma_config function has some variables, that are not needed, uses the macro msdc_init_bd that is only used here and does not use the for_each_sg iterator. That last fact could cause a bug if the scatterlist is chained. The function is changed to remove these things, but none of the changes should change the behavior of it (despite the case of a linked scatterlist). Signed-off-by:

In the current code the hardware reset is realised via a macro and does only wait for a certain ammount of time for the controller to come out of reset state, but it should wait until it IS out of reset state. So it is refactored to improve this, it is also changed from a macro to a function and renamed to msdc_reset_hw to match the mtk-sd driver. Signed-off-by:

The enable|disable_sdio_irq() fields of msdc_hw are never set, so when they are called, they are null pointer. In case of the MSDC_EXT_SDIO_IRQ flag set in msdc0_hw, this happens. But because these fields are never set, they can simply be removed. Signed-off-by:
