Outdated
There was a problem hiding this comment.
This should stay so that it does not take disabled instances into account

Merged as part of nrfconnect/sdk-zephyr#2385 |
Reopening as the commits still need to be merged upstream. In the above PR, they were only cherry-picked into the downstream fork. |
|
Rebased. |
|
ah my bad :) I did not notice this one was upstream :) |
|
is the DNM intentional? |

Add clock source for timer120 and timer121 nodes Signed-off-by: Krzysztof Chruściński <[email protected]>
Add requesting for global HFSLL when fast instance TIMER (e.g. TIMER120 in nrf54h20) is used. Signed-off-by: Krzysztof Chruściński <[email protected]>
Request fast global domain to run at 320 MHz during fast UARTE activity. As request is asynchronous it cannot be called from an ISR. Due to complexity to handle that without device runtime power management a requirement is added so that if fast UARTE is used device runtime PM must be enabled. Clock is request and released in PM resume and suspended actions which in case of fast UARTE are only called from thread context. Signed-off-by: Krzysztof Chruściński <[email protected]>
Enable device runtime PM for nrf54h20dk/nrf54h20/cpuapp where fast UARTE (uart120) is tested. Signed-off-by: Krzysztof Chruściński <[email protected]>

Added clock request and release in resume and suspend actions. It is required for the fast UARTE peripheral (uart120 in nrf54h20). Since it would be tricky to handle that outside of PM actions added build time check which enforces use of device runtime PM when fast UARTE is used (device power PM is de facto a must in nrf54h20 so it is not a real limitation).
Due to device runtime PM requirement,
uart_async_apitest configuration for nrf54h20dk/nrf54h20/cpuapp has been extended to enable PM.Work from PR #81527 had to be included.DNM until #81735.
