2015-11-05T21:15:12+00:00

Pull spi updates from Mark Brown:
 "Quite a lot of activity in SPI this cycle, almost all of it in drivers
  with a few minor improvements and tweaks in the core.

   - Updates to pxa2xx to support Intel Broxton and multiple chip selects.
   - Support for big endian in the bcm63xx driver.
   - Multiple slave support for the mt8173
   - New driver for the auxiliary SPI controller in bcm2835 SoCs.
   - Support for Layerscale SoCs in the Freescale DSPI driver"

spi: Drop owner assignment from spi_drivers

2015-10-28T01:30:17+00:00

An spi_driver does not need to set an owner, it will be populated by the
driver core.

staging: fbtft: fix voltage settings for C-Berry28

2015-10-25T02:42:37+00:00

This patch fixes some internal voltage settings for the C-Berry28 display.
The original example source files for the C-Berry28 as provided by
its vendor admatec contained six issues where a command parameter's value
didn't match its corresponding comment.
I've informed admatec about these discrepancies on 2015-08-25. In the
meantime, I've assumed the comments to be more reliable than the code,
and thus have used these values to write the initial C-Berry28 driver.
After having received a reply from admatec on 2015-10-16 that the issues
have been fixed in their example code, it has turned out that for the
voltages VCOM and AVDD, the code was indeed correct, but the comments
were wrong. This patch is meant to fix these two pending mistakes.

staging: fbtft: use init function instead of init sequence

2015-10-25T02:42:37+00:00

This patch converts the default init sequence of the ST7789V
display controller into an init function, as init sequences
are considered deprecated by the maintainers of fbtft.

staging: fbtft: remove redundant set_addr_win() function

2015-10-25T02:42:37+00:00

This patch removes the function set_addr_win() from fb_st7789v.c, as its
definition is redundant to the default implementation fbtft_set_addr_win()
which can be found in fbtft-core.c.

staging: fbtft: use MIPI DCS for ST7789V and C-Berry28

2015-10-25T02:42:37+00:00

This patch makes use of the standard MIPI Display Command Set to remove
redundant entries from the command enum of the ST7789V display controller
and also some of the magic constants found in the init sequence of the
C-Berry28 display.

Staging: fbtft: fb_ssd1331: Remove unnecessary cast

2015-10-17T05:56:23+00:00

Compiler can typecast variables implicitly so, explicit type cast is not
required and should be removed.
