[PATCH v2 30/36] soc: fsl: cpm1: qmc: Rename SCC_GSMRL_MODE_QMC

[Christophe Leroy]

Le 08/08/2024 à 09:11, Herve Codina a écrit :
> Current code handles CPM1 version of QMC. Even if GSMRL is specific to
> the CPM1 version, the exact same purpose and format register (GUMRL) is
> present in the QUICC Engine (QE) version of QMC. Compared to the QE
> version, the values defined for the mode bitfield are different and the
> 0x0A value defined for the QMC mode is CPM1 specific.
> 
> In order to prepare the support for the QE version, rename this bitfield
> value to clearly identify it as CPM1 specific.
