      tty: Added a CONFIG_TTY option to allow removal of TTY · 4f73bc4d
      Joe Millenbach authored
      The option allows you to remove TTY and compile without errors. This
      saves space on systems that won't support TTY interfaces anyway.
      bloat-o-meter output is below.
      
      The bulk of this patch consists of Kconfig changes adding "depends on
      TTY" to various serial devices and similar drivers that require the TTY
      layer.  Ideally, these dependencies would occur on a common intermediate
      symbol such as SERIO, but most drivers "select SERIO" rather than
      "depends on SERIO", and "select" does not respect dependencies.
      
      bloat-o-meter output comparing our previous minimal to new minimal by
      removing TTY.  The list is filtered to not show removed entries with awk
      '$3 != "-"' as the list was very long.

      Input: egalax_ts - get gpio from devicetree · ae495e84
      Hui Wang authored
      The irq_to_gpio() is old, most platforms use GENERIC_GPIO framework
      and don't support this API anymore.
      
      The i.MX6q sabrelite platform equips an egalax touchscreen controller,
      and this platform already transfered to GENERIC_GPIO framework, to
      support this driver, we use a more generic way to get gpio.
      
      Add a return value checking for waking up the controller in the probe
      function, this guarantee only a workable device can pass init.
      
      [dmitry.torokhov@gmail.com: Make driver depend on CONFIG_OF as it is
       now required.]

      ARM: S3C24XX: change the ARCH_S3C2410 to ARCH_S3C24XX · b130d5c2
      Kukjin Kim authored
      This patch changes the ARCH name to "ARCH_S3C24XX" for Samsung
      S3C2410, S3C2412, S3C2413, S3C2416, S3C2440, S3C2442, S3C2443,
      and S3C2450 SoCs so that we can merge the mach-xxx directories
      and plat-s3c24xx dir. to just one mach-s3c24xx for them.
      
      I think this should be sent to upstream via samsung tree because
      this touches many samsung stuff.

      Input: add driver for AUO In-Cell touchscreens using pixcir ICs · 5245db49
      Heiko Stübner authored
      Some displays from AUO have a so called in-cell touchscreen, meaning it
      is built directly into the display unit.
      
      Touchdata is gathered through PIXCIR Tango-ICs and processed in an
      Atmel ATmega168P with custom firmware. Communication between the host
      system and ATmega is done via I2C.
      
      Devices using this touch solution include the Dell Streak5 and the family
      of Qisda ebook readers.
      
      The driver reports single- and multi-touch events including touch area
      values.

      kconfig: rename CONFIG_EMBEDDED to CONFIG_EXPERT · 6a108a14
      David Rientjes authored
      The meaning of CONFIG_EMBEDDED has long since been obsoleted; the option
      is used to configure any non-standard kernel with a much larger scope than
      only small devices.
      
      This patch renames the option to CONFIG_EXPERT in init/Kconfig and fixes
      references to the option throughout the kernel.  A new CONFIG_EMBEDDED
      option is added that automatically selects CONFIG_EXPERT when enabled and
      can be used in the future to isolate options that should only be
      considered for embedded systems (RISC architectures, SLOB, etc).
      
      Calling the option "EXPERT" more accurately represents its intention: only
      expert users who understand the impact of the configuration changes they
      are making should enable it.
