Currently, ns16550 allows the user to specify a clock attribute in the Device Tree. This node is use to retrieve the internal frequency of the hardware block. However, ns16550 expects the clock is already initialised and it doesn't try to enable it. Let's fix that issue. Signed-off-by: Jérôme Pouiller <[email protected]>
WiseConnect SDK is need for Silabs SiWx91x series. Signed-off-by: Jérôme Pouiller <[email protected]>
This driver is mostly the initial seed for further implementation of a real clock driver. It doesn't allow the user to choose the clock source for the various peripherals. The driver hardcodes some sane values. Signed-off-by: Jérôme Pouiller <[email protected]>

Implement DMA driver for siwx917 using UDMA peripheral. For now, Scatter/Gather DMA is not yet supported. Signed-off-by: Jérôme Pouiller <[email protected]>
Report DMA configuration in the board definitions. Note the addresses of the DMA buffers are hardcoded in the HAL. So, these areas have to be declared in the linker file. Signed-off-by: Jérôme Pouiller <[email protected]>

Add flash driver for Silicon Labs SiWx91x family. Co-authored-by: Martin Hoff <[email protected]> Signed-off-by: Martin Hoff <[email protected]> Signed-off-by: Jérôme Pouiller <[email protected]>
A specific section of the flash on the SiWx917 is reserved for the Network co-processor (NWP). This zone needs to be delimited in order to not overwrite it. We then need to use "code-partition" to provide Zephyr the application code flash location.

Report Bluetooth HCI declaration in the board definitions. Signed-off-by: Jérôme Pouiller <[email protected]>
This driver allow to use Zephyr native IP stack or the IP stack provided
by HAL / WiseConnect.
The WiseConnect implementation may take advantage of the specific
features provided by the 917 (power consumption, speed,
validation...).
Some notable features are not available with this interface:
- It seems Zephyr does not provide API to offload multicast membership
management. User should be to directly call WiseConnect APIs
- Support for ICMP frames is difficult. Note that WiseConnect
automatically answer to ping request. It is just not possible to
send ping requests and receive ping responses.
- Zephyr and WiseConnect both support TLS offloading. However this
patch does not implement it.
- Reentrancy in the WiseConnect side is uncertain.
This implementation has been tested with samples/net/wifi/ (which relies
on subsys/net/lib/shell).

This should probably go before the source "drivers/bluetooth/hci/Kconfig.silabs" line, so that options specific to the 917 HCI driver can be put into Kconfig.silabs
There was a problem hiding this comment.
Actually, I think it'd be even justified to move the top-level Silabs driver options into that file too, however if the current situation is the common practice for HCI drivers we can do the refactoring in a later PR too.
