Subject: Re: [PATCH 00/33] thermal: exynos: convert the driver to use per-SoC
 type operations


Hi,

Eduaro/Amit, any comments on this series?
Could it be merged for v3.19?

[ Currently this series conflicts with "[PATCH] thermal: exynos: fix IRQ
  clearing on TMU initialization" patch so I'm planning to refresh it but
  it would be great to get some feedback first. ]

Best regards,
