Subject: [U-Boot] [PATCH v3 0/2] x86: SCU and PMU drivers for Intel MID
Date: Sat, 1 Apr 2017 16:21:32 +0300 [thread overview]
Message-ID: <20170401132134.62092-1-andriy.shevchenko@linux.intel.com> (raw)
There are two crucial drivers to make Intel MID platforms functional in
U-Boot:
SCU which stands for System Controller Unit
PMU which stands for Power Management Unit
Since v2:
- resend with cover letter including changes from previous versions
Since v1:
Common:
- convert to use REGMAP instead of constant addressed IO
- rewrite as UCLASS_SYSCON modules
- move to arch/x86/lib since it's related to x86 only and there are
already another UCLASS_SYSCON modules there
SCU:
- convert function documentation to have header and body and be
consistent
- shrink header and remove unneeded attributes
- drop busy loop counter from 3m to 100k as per driver in Linux kernel
PMU:
- convert to be more generic and move Tangier related part to its own
folder (the latter out of scope of this series)
