      auxdisplay: img-ascii-lcd: driver for simple ASCII LCD displays · 0cad855f
      Paul Burton authored 
      
Add a driver for simple ASCII LCD displays found on the MIPS Boston,
Malta & SEAD3 development boards. The Boston display is an independent
memory mapped device with a simple memory mapped 8 byte register space
containing the 8 ASCII characters to display. The Malta display is
exposed as part of the Malta board registers, and provides 8 registers
each of which corresponds to one of the ASCII characters to display. The
SEAD3 display is slightly more complex, exposing an interface to an
S6A0069 LCD controller via registers provided by the boards CPLD.
However although the displays differ in their register interface, we
require similar functionality on each board so abstracting away the
differences within a single driver allows us to share a significant
amount of code & ensure consistent behaviour.

The driver displays the Linux kernel version as the default message, but
allows the message to be changed via a character device. Messages longer
then the number of characters that the display can show will scroll.

This provides different behaviour to the existing LCD display code for
the MIPS Malta or MIPS SEAD3 platforms in the following ways:

  - The default string to display is not "LINUX ON MALTA" or "LINUX ON
    SEAD3" but "Linux" followed by the version number of the kernel
    (UTS_RELEASE).

  - Since that string tends to be significantly longer it scrolls twice
    as fast, moving every 500ms rather than every 1s.

  - The LCD won't be updated until the driver is probed, so it doesn't
    provide the early "LINUX" string.

      MAINTAINERS: Update powerpc website & add selftests · ad654f25
      Michael Ellerman authored 
      
The selftests under tools/testing/selftests/powerpc are maintained by
us, so add a file pattern for them.

Also drop the www.penguinppc.org link, it's not dead, but the site is
dead (database error). Instead link to the wiki attached to our github,
there is some info there which may be useful, which is better than none.

      MAINTAINERS: Drop separate pseries entry · 55099115

Paul is no longer acting as a separate maintainer for pseries, it is
handled along with the rest of powerpc. The URL no longer links anywhere
meaningful, so drop it also.

The platform is old, very few users and I lack bandwidth to keep after
it these days.

Mark the base platform as well as the drivers as orphans, patches have
been flowing through the fallback maintainers for a while already.

      iio: 104-quad-8: Add IIO support for the ACCES 104-QUAD-8 · 28e5d3bb
      William Breathitt Gray authored 
      
The ACCES 104-QUAD-8 is a general purpose quadrature encoder
counter/interface board. The 104-QUAD-8 is capable of monitoring the
outputs of eight encoders via four on-board LSI/CSI LS7266R1 24-bit
dual-axis quadrature counter chips. Core functions handled by the
LS7266R1, such as direction and total count, are available.

Performing a write to a counter's IIO_CHAN_INFO_RAW sets the counter and
also clears the counter's respective error flag. Although the counters
have a 25-bit range, only the lower 24 bits may be set, either directly
or via a counter's preset attribute. Interrupts are not supported by
this driver.

This driver adds IIO support for the ACCES 104-QUAD-8 and ACCES
104-QUAD-4. The base port addresses for the devices may be configured
via the base array module parameter.
