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.

+The Imagination Technologies SPDIF Input controller contains the following

+
+This control returns a mask that shows which of the IEC958 status bits
+can be read using the 'IEC958 Capture Default' control.
+
+name='IEC958 Capture Default',index=0
+
+This control returns the status bits contained within the SPDIF stream that
+is being received. The 'IEC958 Capture Mask' shows which bits can be read
+from this control.
+
+name='SPDIF In Multi Frequency Acquire',index=0
+name='SPDIF In Multi Frequency Acquire',index=1
+name='SPDIF In Multi Frequency Acquire',index=2
+name='SPDIF In Multi Frequency Acquire',index=3
+
+This control is used to attempt acquisition of up to four different sample
+rates. The active rate can be obtained by reading the 'SPDIF In Lock Frequency'
+control.
+
+When the value of this control is set to {0,0,0,0}, the rate given to hw_params
+will determine the single rate the block will capture. Else, the rate given to
+hw_params will be ignored, and the block will attempt capture for each of the
+four sample rates set here.
+
+If less than four rates are required, the same rate can be specified more than
+once
+
+name='SPDIF In Lock Frequency',index=0
+
+This control returns the active capture rate, or 0 if a lock has not been
+acquired
+
+name='SPDIF In Lock TRK',index=0
+
+This control is used to modify the locking/jitter rejection characteristics
+of the block. Larger values increase the locking range, but reduce jitter
+rejection.
+
+name='SPDIF In Lock Acquire Threshold',index=0
+
+This control is used to change the threshold at which a lock is acquired.
+
+name='SPDIF In Lock Release Threshold',index=0
+
+This control is used to change the threshold at which a lock is released.

+ depends on KVM
+ default y
+ 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.

- VFIO is built on the ability to isolate devices using the IOMMU.
- Only with an IOMMU can userspace access to DMA capable devices be
- considered secure. VFIO No-IOMMU mode enables IOMMU groups for
- devices without IOMMU backing for the purpose of re-using the VFIO
- infrastructure in a non-secure mode. Use of this mode will result
- in an unsupportable kernel and will therefore taint the kernel.
- Device assignment to virtual machines is also not possible with
- this mode since there is no IOMMU to provide DMA translation.

+/* Support code for asymmetrically connected dgram sockets
+ *
+ * If a datagram socket is connected to a socket not itself connected
+ * to the first socket (eg, /dev/log), clients may only enqueue more
+ * messages if the present receive queue of the server socket is not
+ * "too large". This means there's a second writeability condition
+ * poll and sendmsg need to test. The dgram recv code will do a wake
+ * up on the peer_wait wait queue of a socket upon reception of a
+ * datagram which needs to be propagated to sleeping would-be writers
+ * since these might not have sent anything so far. This can't be
+ * accomplished via poll_wait because the lifetime of the server
+ * socket might be less than that of its clients if these break their
+ * association with it or if the server socket is closed while clients
+ * are still connected to it and there's no way to inform "a polling
+ * implementation" that it should let go of a certain wait queue
+ *
+ * In order to propagate a wake up, a wait_queue_t of the client
+ * socket is enqueued on the peer_wait queue of the server socket
+ * whose wake function does a wake_up on the ordinary client socket
+ * wait queue. This connection is established whenever a write (or
+ * poll for write) hit the flow control condition and broken when the
+ * association to the server socket is dissolved or after a wake up
+ * was relayed.
