Compared to the old xrx200_phy_fw driver the new version has multiple
enhancements. The name of the firmware files does not have to be added
to all .dts files anymore - one now configures the GPHY mode (FE or GE)
instead. Each GPHY can now also boot separate firmware (thus mixing of
GE and FE GPHYs is now possible).
The new implementation is based on the RCU syscon-mfd and uses the
reeset_controller framework instead of raw RCU register reads/writes.Signed-off-by: Martin Blumenstingl

Instead of hacking the configuration of the FPI bus into the arch code
add an own bus driver for this internal bus. The FPI bus is the main

will probably also be used on different SoCs later.Signed-off-by: Hauke Mehrtens

Commit b6a1d093f96b ("PM / Domains: Extend generic power domain
debugfs") now creates a debugfs directory for each genpd based on the
name of the genpd. Currently no name is given to the genpd created by
ti_sci_pm_domains driver so because of this we see a NULL pointer
dereferences when it is accessed on boot when the debugfs entry creation
is attempted.Give the genpd a name before registering it to avoid this.

Allwinner A64's display engine claims the SRAM C section to work.
Add support for the A64 SRAM controller and the SRAM C section of it.
Signed-off-by: Icenowy Zheng
Signed-off-by: Chen-Yu Tsai -
On some Allwinner SoCs, sometimes the value needed to write into the
register to claim SRAM is not equal to the value specified in the
device tree.The device tree binding defines 0 as "mapped to CPU" and 1 as "mapped
to X device". This matches the value written to the configuration
register for the SRAM blocks currently supported. However, the not yet
supported VE SRAM block is claimed for the device by writing 0x7fffffff,
which is vastly different from the other blocks. On the A64, SRAM C is
claimed by the device by writing a 0, which is the opposite of the
current design.Add a value remapping in sunxi_sram_func structure, and let the
sunxi_sram_of_parse function set the remapped register value.
This allows us to keep the convention currently used in the device tree
binding.Signed-off-by: Icenowy Zheng
[wens@csie.org: Clarified commit message]
Signed-off-by: Chen-Yu Tsai -
When claiming SRAM, if the base is set to an error, it means that the
SRAM controller has been probed, but failed to remap the controller
memory zone. If the base is zero, thus the SRAM controller should be not
probed at all, and it should return -EPROBE_DEFER. However, currently we
returned -EPROBE_DEFER in the former situation, and ignored the latter
situation (which will lead to the kernel to panic).Fix the behavior on abnormal base address processing when claiming.

By switching to the request_firmware_into_buf() we load the segment data
straight into the preallocated buffers, reducing the need for allocating
scratch buffers for these. In particular the modem firmware consists of
multiple segments in the range 5-15MB, making this worth while.Signed-off-by: Bjorn Andersson

of_find_node_with_property() drops the reference to the 'from' node,
which eventually (after enough -EPROBE_DEFERs) drops the last reference
to the node causing all sorts of fun problems, and this nice splat.BUG: sleeping function called from invalid context at ../kernel/locking/mutex.c:747

If a regulator requests a deferred probe, the power domain gets
initialized twice. This leads to a list double add (without
list debugging the kernel hangs due to the double add later):WARNING: CPU: 0 PID: 19 at lib/list_debug.c:31 __list_add_valid+0xbc/0xc4
list_add double add: new=c1229754, prev=c12383b4, next=c1229754.Initialize the power domain after we get the regulator. Also do
not print an error in case the regulator defers probing.Cc: Fabio Estevam

This driver register as a subsystem restart notifier and will send out
notifications to remote processors that has opened the "glink_ssr" GLINK
channel.This mechanism is used to signal any GLINK participants that a 3rd party
is gone and that the communication state has to be reset; i.e. that read
and write pointers of the GLINK FIFOs are stale.Acked-by: Andy Gross
