      i2c: ismt: initialize DMA buffer · bf416910
      James Ralston 提交于
      This patch adds code to initialize the DMA buffer to compensate for
      possible hardware data corruption.

      i2c: designware: 10-bit addressing mode enabling if I2C_DYNAMIC_TAR_UPDATE is set · bd63ace4
      Chew, Chiau Ee 提交于
      According to Designware I2C spec, if I2C_DYNAMIC_TAR_UPDATE is set to 1,
      the 10-bit addressing mode is controlled by IC_10BITADDR_MASTER bit of
      IC_TAR register instead of IC_CON register. The IC_10BITADDR_MASTER
      in IC_CON register becomes read-only copy. Since I2C_DYNAMIC_TAR_UPDATE
      value can't be detected from hardware register, so we will always set the
      IC_10BITADDR_MASTER bit in both IC_CON and IC_TAR register whenever 10-bit
      addresing mode is requested by user application.

      i2c: mv64xxx: Do not use writel_relaxed() · 85b3a935
      Thierry Reding 提交于
      The driver is used on PowerPC which don't provide writel_relaxed(). This
      breaks the c2k and prpmc2800 default configurations. To fix the build,
      turn the calls to writel_relaxed() into writel(). The impacts for ARM
      should be minimal.

      Some functions and variables are only used if the configuration selects
      HAVE_CLK. Protect them with a corresponding #ifdef CONFIG_HAVE_CLK block
      to avoid compiler warnings.

      i2c: s3c2410: fix clk_disable/clk_unprepare WARNings · 15336913
      Kim Phillips 提交于
      commit d16933b3 "i2c: s3c2410: Move
      location of clk_prepare_enable() call in probe function" refactored
      clk_enable and clk_disable calls yet neglected to remove the
      clk_disable_unprepare call in the module's remove().
      
      It helps remove warnings on an arndale during unbind:
      
      echo 12c90000.i2c > /sys/bus/platform/devices/12c90000.i2c/driver/unbind
