Subject: remoteproc: qcom_q6v5_mss: Add modem support on MSM8926
X-Git-Tag: v6.15-rc1~104^2~19
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=df9e5103a2855ba3352f2c6e862adad17810605c;p=thirdparty%2Flinux.git

remoteproc: qcom_q6v5_mss: Add modem support on MSM8926

While MSM8926 being 'just' an LTE-capable variant of MSM8226 it appears
the modem setup has changed significantly, by requiring mss-supply and
not using the ext-bhs-reg.

Add a new compatible and new struct to support that.
