From f3022c6ca06e0b8d8e77c94da1af5f41210e52ba Mon Sep 17 00:00:00 2001 From: Maxime Ripard Date: Sun, 3 May 2015 09:25:41 +0200 Subject: ARM: sunxi: dt: Split the SPI pinctrl groups The pinctrl groups for SPI until now were also adding the chip selects in the SPI pinctrl group. This was causing a few issues, since a board was forced to use a random number of chipselects, even though it might use one of these chip selects for another pin. The number of chipselects defined was also not the same from one group to another because of different needs at the time these groups have been introduced, resulting in no clear view from the board DTS on what exactly is being muxed, which even might change in the future. Solve this by creating different pinctrl groups for the chipselects and the standard SPI pins (CLK, MOSI and MISO) so that we fix both issues.
