[PATCH 2/2] pinctrl: mvebu: add pinctrl driver for Armada XP

Sebastian Hesselbarth sebastian.hesselbarth at gmail.com
Tue Jul 22 11:10:48 PDT 2014


This adds a pinctrl driver for pin muxing on Marvell Armada XP. The
driver is ported from Linux and modified to fit on Barebox's common
mvebu pinctrl driver.

+ * both have 67 MPP pins (more GPIOs and address lines for the memory
+ * bus mainly). The only difference between the mv78260 and the
+ * mv78460 in terms of pin muxing is the addition of two functions on
+ * pins 43 and 56 to access the VDD of the CPU2 and 3 (mv78260 has two
+ * cores, mv78460 has four cores).
