The device tree documentation for the keystone machines are located at
Documentation/devicetree/bindings/arm/keystone/keystone.txt
-Known issues & workaround
--------------------------
-
-Some of the device drivers used on keystone are re-used from that from
-DaVinci and other TI SoCs. These device drivers may use clock APIs directly.
-Some of the keystone specific drivers such as netcp uses run time power
-management API instead to enable clock. As this API has limitations on
-keystone, following workaround is needed to boot Linux.
-
- Add 'clk_ignore_unused' to the bootargs env variable in u-boot. Otherwise
- clock frameworks will try to disable clocks that are unused and disable
- the hardware. This is because netcp related power domain and clock
- domains are enabled in u-boot as run time power management API currently
- doesn't enable clocks for netcp due to a limitation. This workaround is
- expected to be removed in the future when proper API support becomes
- available. Until then, this work around is needed.

+ help
+ This option adds an alternative code sequence to work around ARM
+ erratum 834220 on Cortex-A57 parts up to r1p2.
+
+ Affected Cortex-A57 parts might report a Stage 2 translation
+ fault as the result of a Stage 1 fault for load crossing a
+ page boundary when there is a permission or device memory
+ alignment fault at Stage 1 and a translation fault at Stage 2.
+
+ The workaround is to verify that the Stage 1 translation
+ doesn't generate a fault before handling the Stage 2 fault.
+ Please note that this does not necessarily enable the workaround,
+ as it depends on the alternative framework, which will only patch
+ the kernel if an affected CPU is detected.
+
+ If unsure, say Y.

+ This driver is for ADM8211A, ADM8211B, and ADM8211C based cards.
+ These are PCI/mini-PCI/Cardbus 802.11b chips found in cards such as:
+
+ Xterasys Cardbus XN-2411b
+ Blitz NetWave Point PC
+ TrendNet 221pc
+ Belkin F5D6001
+ SMC 2635W
+ Linksys WPC11 v1
+ Fiberline FL-WL-200X
+ 3com Office Connect (3CRSHPW796)
+ Corega WLPCIB-11
+ SMC 2602W V2 EU
+ D-Link DWL-520 Revision C
+
+ However, some of these cards have been replaced with other chips
+ like the RTL8180L (Xterasys Cardbus XN-2411b, Belkin F5D6001) or
+ the Ralink RT2400 (SMC2635W) without a model number change.
+
+ Thanks to Infineon-ADMtek for their support of this driver.
