      spi_s3c24xx: add FIQ pseudo-DMA support · bec0806c
      Ben Dooks 提交于
      Add pseudo-DMA by FIQ to the S3C24XX SPI driver.  This allows the driver
      to get DMA-like performance where there are either no free DMA channels or
      when doing transfers that required both TX and RX data paths.
      
      Since this patch requires the addition of an assembly file to hold the FIQ
      code, we rename the module (instead of adding a rename of the .c file to
      this patch).  We expect most users are loading this via udev and thus
      there should be no change to the userland configuration.

      This is due the fact that uart_list list was populated in
      omap_serial_early_init() and omap_uart_enable_irqs() went through this
      list even when serial idle wasn't enabled for all uarts.
      
      This patch moves the code that populates the uart_list and enables uart
      clocks into omap_serial_init_port().

      mfd: twl: fix twl4030 rename for remaining driver, board files · ebeb53e1
      Balaji T K 提交于
      Recent drivers/mfd/twl4030* renames to twl broke compile for
      various boards as the series was missing a patch to change
      the board-*.c files.
      
      This patch renames include twl4030.h to include twl.h
      and also renames twl4030_i2c_ routines.
