dma: dw: Common dw dma driver functionality Move most of the designware driver into a common compile unit with a a header that exposes the common functionality. This allows for derivative hardware, such as that in intel's adsp (cavs) to use the common functionality while extending. Signed-off-by: Tom Burdick <thomas.burdick@intel.com>

# DesignWare DMA configuration options
kconfig: Clean up header comments and make them consistent Use this short header style in all Kconfig files: # <description> # <copyright> # <license> ... Also change all <description>s from # Kconfig[.extension] - Foo-related options to just # Foo-related options It's clear enough that it's about Kconfig. The <description> cleanup was done with this command, along with some manual cleanup (big letter at the start, etc.) git ls-files '*Kconfig*' | \ xargs sed -i -E '1 s/#\s*Kconfig[\w.-]*\s*-\s*/# /' Signed-off-by: Ulf Magnusson <Ulf.Magnusson@nordicsemi.no>

drivers: dma: introduce Intel CAVS DMA Introduce the Intel CAVS DMA. This is based out of the DesignWare DMA IP but the register offset and bits have been changed in some cases. However, the fundamental definition for the register field has not been changed. Hence the registers begin with "DW_" to indicate the Designware origin. This driver currently supports the single block mode and linked list multi-block mode. Scatter-Gather is not supported.

drivers/dma: Rename CAVS driver to DesignWare There is no such thing as CAVS DMA IP block, the DMA IP block found on CAVS based chips is made with DesignWare one. This will help to centralize DW based DMA device into one driver. Signed-off-by: Tomasz Bursztyka <tomasz.bursztyka@linux.intel.com>

kconfig: remove Enable from boolean prompts According to Kconfig guidelines, boolean prompts must not start with "Enable...". The following command has been used to automate the changes in this patch: sed -i "s/bool \"[Ee]nables\? \(\w\)/bool \"\U\1/g" **/Kconfig* Signed-off-by: Gerard Marull-Paretas <gerard.marull@nordicsemi.no>

DesignWare DMA driver.
dma/dw_common: Update dma_dw_common from sof Ports the SOF DesignWare DMA code to Zephyr. Effectively replaces much of what was the designware driver as this driver enables scatter gather which the older driver did not. * Enables cyclic transfer description lists when the cyclic config param is given. * Enables linear link position usage with cAVS GPDMA. * Passes suspend/resume, scatter/gather tests. * Provides status updates of the transfer through dma_get_status() * Enables reloading a cyclic transfer with dma_reload() * Enables dma handshakes using the dma_slot config param. * cAVS specifics remain in the dma_cavs_gpdma driver.
