[PATCH v1 0/6] ARM: Add GXP Fan and SPI controllers

[nick . hawkins]

From: Nick Hawkins <nick.hawkins@xxxxxxx>

The GXP SoC can support up to 16 fans through the interface provided by
the CPLD. The fans speeds are controlled via a pwm value 0-255. The fans
are also capable of reporting if they have failed to the CPLD which in
turn reports the status to the GXP SoC. Based on previous feedback the
registers required for fan control have been regmaped individualy to fan
driver. Specifically these registers are the function 2 registers and the
programmable logic registers from the CPLD. Additionally in this patchset
there is support for the SPI driver which already exists as spi-gxp.c in
the SPI driver.
