This is a backport of the patches accepted to the Linux mainline related to mvebu SoC (Armada XP and Armada 370) between Linux v3.12, and Linux v3.13. This work mainly covers: * Finishes work for sharing the pxa nand driver(drivers/mtd/nand/pxa3xx_nand.c) between the PXA family, and the Armada family. * timer initialization update, and access function for the Armada family. * Generic IRQ handling backporting. * Some bug fixes.

Subject: [PATCH 193/203] clocksource: armada-370-xp: Fix device-tree binding
|
|
|
|
This commit fixes the DT binding for the Armada 370/XP SoC timer.
|
|
The previous "marvell,armada-370-xp-timer" compatible is removed and
|
|
two new compatible strings are introduced: "marvell,armada-xp-timer"
|
|
and "marvell,armada-370-timer".
|
|
|
|
The rationale behind this change is that the Armada 370 SoC and the
|
|
Armada XP SoC timers are not really compatible:
|
|
|
|
* Armada 370 has no 25 MHz fixed timer.
|
|
|
|
* Armada XP cannot work properly without such 25 MHz fixed timer
|
|
as doing otherwise leads to using a clocksource whose frequency
|
|
varies when doing cpufreq frequency changes.
|
|
|
|
This commit also removes the "marvell,timer-25Mhz" property, given
|
|
it's now meaningless.

Required properties:
|
|
-- compatible: Should be "marvell,armada-370-xp-timer"
|
|
+- compatible: Should be either "marvell,armada-370-timer" or
|
|
+ "marvell,armada-xp-timer" as appropriate.
|
|
- interrupts: Should contain the list of Global Timer interrupts and
|
|
then local timer interrupts
|
|
- reg: Should contain location and length for timers register. First
|
|
pair for the Global Timer registers, second pair for the
|
|
local/private timers.
