Subject: [PATCH] [nrf fromtree] dts: common: nordic: nrf54l: Add hfpll clock
 source
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Add 128 MHz clock source and use it for uart00. Baudrate setting
must be adjusted based on uart clock source so without this
change there is wrong baudrate on uart00.

Signed-off-by: Krzysztof Chruściński <krzysztof.chruscinski@nordicsemi.no>
(cherry picked from commit 923d313a04726f6475b19ef803eb8b5a080e91d7)
