Not explained why you need it and really no point. Best regards, Krzysztof

I will try to address them/add more context for these changes in V4.

From: Ciprian Marian Costea <ciprianmarian.costea@oss.nxp.com> LINFlexD UART driver is used by S32 SoC family. Add clocking support as optional in order to not break existing support for S32V234 SoC. A separate patch adding clock definitions to the S32G2/S32G3 based boards devicetree will be sent for review. Changes in V3: - Fixed an error reported by 'dt_bindings_check' Changes in V2: - Updated bindings by adding more information related to required LINFlexD clocks Ciprian Marian Costea (2): dt-bindings: linflexuart: add clock definitions serial: fsl_linflexuart: add clock support .../bindings/serial/fsl,s32-linflexuart.yaml | 29 ++++++++ drivers/tty/serial/fsl_linflexuart.c | 67 ++++++++++++++----- 2 files changed, 80 insertions(+), 16 deletions(-)
