      [ARM] S3C64XX: Initial support for DVFS · b3748ddd
      Mark Brown 提交于
      This patch provides initial support for CPU frequency scaling on the
      Samsung S3C ARM processors. Currently only S3C6410 processors are
      supported, though addition of another data table with supported clock
      rates should be sufficient to enable support for further CPUs.
      
      Use the regulator framework to provide optional support for DVFS in
      the S3C cpufreq driver. When a software controllable regulator is
      configured the driver will use it to lower the supply voltage when
      running at a lower frequency, giving improved power savings.
      
      When regulator support is disabled or no regulator can be obtained
      for VDDARM the driver will fall back to scaling only the frequency.

      [ARM] S3C64XX: Add S3C6400 SDHCI setup support · 4faf6867
      Ben Dooks 提交于
      Add support for S3C6400 SDHCI channels 0 and 1, making
      the GPIO code common to both S3C6400 and S3C6410.

      [ARM] S3C64XX: Add IRQ PM code · 966bcc14
      Ben Dooks 提交于
      Add support for saving the state of the IRQ registers over suspend.
      
      This requires moving the S3C64XX UART registers into <plat/regs-serial.h>
      and adding irq-pm.c which saves the state of all the IRQ registers.
      
      The irq-pm.c saves all the IRQ registers, including the IRQ_EINT and
      IRQ_EINT_GROUP registers as it was easier than adding three different
      files. Also ensuring that all the registers are restored to the same
      state as before suspend is considered to be the best thing to do.
      
      Note, we do not suspend the VIC here, this is done by the VIC driver
      itself.

      [ARM] S3C64XX: Initial support for PM (suspend to RAM) · bd117bd1
      Ben Dooks 提交于
      Add the initial support for the S3C64XX based systems to use
      suspend-to-RAM to sleep.
      
      Includes basic debugging for use with the SMDK6410 usign the
      LEDs on the baseboard.
