Hi Chris, Mike, Stephen, On Thu, Dec 15, 2016 at 6:00 PM, Chris Brandt [off-list ref] wrote:
The RZ/A1 is different than the other Renesas SOCs because the MSTP registers are 8-bit instead of 32-bit and if you try writing values as 32-bit nothing happens...meaning this driver never worked for r7s72100.
Thanks for your patch! The only reason it ever worked was that almost all module clocks are enabled at boot time...

Mike/Stephen: as this is a fix for stable (v3.16+), can you please take it
directly?
Thanks!
