Subject: powerpc/windfarm: Add detection for second cpu pump
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=529586dc39b0ec47c6290c4e7bed6ea3ffd1d8fb;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git

powerpc/windfarm: Add detection for second cpu pump

Windfarm SMU control is explicitly missing support for a second CPU pump in G5 PowerMacs. Such machines actually exist  (specifically Quads with a second pump), so this patch adds detection for it.
