4fcdff9bca serial: 8250_omap: introduce "ti,am3352-uart" compatible property
Use of of_machine_is_compatible() for handling AM335x specific
"DMA kick" quirk in 8250_omap driver makes it ugly to extend the
quirk for other platforms. Instead use a new compatible.

The new compatible will also make it easier to take care of
other quirks on AM335x and like SoCs.

In order to not break backward DTB compatibility for users of
8250_omap driver on AM335x based boards, existing use of
of_machine_is_compatible() has not been removed.

9a258afa92 ARM: OMAP2+: hwmod: Fix _wait_target_ready() for hwmods without sysc
For hwmods without sysc, _init_mpu_rt_base(oh) won't be called and so
_find_mpu_rt_port(oh) will return NULL thus preventing ready state check
on those modules after the module is enabled.

This can potentially cause a bus access error if the module is accessed
before the module is ready.

Fix this by unconditionally calling _init_mpu_rt_base() during hwmod
_init(). Do ioremap only if we need SYSC access.

Eventhough _wait_target_ready() check doesn't really need MPU RT port but
just the PRCM registers, we still mandate that the hwmod must have an
MPU RT port if ready state check needs to be done. Else it would mean that
the module is not accessible by MPU so there is no point in waiting
for target to be ready.

e.g. this fixes the below DCAN bus access error on AM437x-gp-evm.

The register offsets of IRQENABLE_MPU_2 and IRQSTATUS_MPU_2 are hardcoded.
This makes it difficult to reuse the code for SoCs like AM437x that have
a single instance of IRQENABLE_MPU and IRQSTATUS_MPU registers.
Hence handling the case using offset of 4 to accommodate single set of IRQ*

9521f492f0 Drop more omap3 legacy board-*.c files for v4.3. This time we're
dropping the board files for omap3logic and omap3pandora.
 
 The reason for dropping these now rather than later is that now
 we can simply revert the patches in case of unexpected issues as
 we are not dropping any platform data at this point.
 
 This leaves us with only the following board-*.c files:
 
 BOARD                   REASON NEEDED
 board-ldp.c             Still used in RMKs boot test system
 board-rx51-*.c          Needs /proc/atags support for user space
 
 Once we have the n900 legacy user space issues sorted out for
 /proc/atags and system_rev, we can drop the remaining two
 board-*.c files. And then one merge window after that we can
 drop the legacy booting support assuming no unexpected issues
 are found.

16) Fix panics on packet scheduler filter replace, from Daniel Borkmann.

17) Make sure AF_PACKET sees properly IP headers in defragmented frames
    (via PACKET_FANOUT_FLAG_DEFRAG option), from Edward Hyunkoo Jee.

18) AF_NETLINK cannot hold mutex in RCU callback, fix from Florian
    Westphal.

7db85dd082 ARM: socfpga: dts: add missing clock gates to socfpga.dtsi
The gates for the clocks coming out of the sdram pll
were missing.  The change adds the missing nodes to
the device tree.

c5dab6e2c1 ARM: socfpga: dts: Correct the parent clock for l3_sp_clk and dbg_clk
The l3_sp_clk's parent should be the l3_mp_clk. This will account for
the extra divider that is present for the l3_mp_clk.

The dbg_clk's parent should be the dbg_at_clk. This will account for
the extra divider that is present for the dbg_at_clk.
