When an MTRR entry is inclusive to a requested range, i.e.
the start and end of the request are not within the MTRR
entry range but the range contains the MTRR entry entirely,

MTRRs contain fixed and variable entries. mtrr_type_lookup()
may repeatedly call __mtrr_type_lookup() to handle a request

__mtrr_type_lookup() also handles the fixed entries, which

Any hardware that can potentially generate DMA has to be locked down from

kernel code. This should be prevented if trusted_kernel has been set, so

The OMAP DMTimer API, omap_dm_timer_set_source(), can set the parent
of a timer node using 3 different values that use fixed parent names
for the clocks. The parent name, timer_sys_ck, is used for setting the
parent when used with the source index OMAP_TIMER_SRC_SYS_CLK. This
should point to the TI
The DT clock aliases for timers using the legacy OMAP timer
device names have been cleaned up. These device names reflect
the names used in legacy boot, and are no longer applicable
as OMAP4 is DT boot only now.

The OMAP DMTimer API, omap_dm_timer_set_source(), uses the clock name
timer_sys_ck for setting a timer's clock source for the source index
OMAP_TIMER_SRC_SYS_CLK. There is currently no clock alias data for
the Timers 13 through 16 for this clock name, so add the same.

The DT clock aliases for Timers use the legacy (non-DT) device
names and a source clock named sys_ck. OMAP5 is DT-boot only,
so correct the DT clock aliases to use the DT device names
instead. Also, the source clock name is corrected from 'sys_ck'
to 'timer_sys_ck', the name used by the OMAP dmtime

The current code expected that every LED had an unique name. This is a
legit expectation when the device tree can no be modified or extended.
But with device tree overlays this requirement can be easily broken.
This patch finds out if the name is already in use and adds the suffix

DSI core registers in DSI6G are compatible with the old versions.
The offsets are 4-byte shift down because of the addition of a
HW_VERSION register. This difference will be handled in source code.
DSI PHY registers are incompatible. This change adds a new domain
for 28nm PHY and PHY regulator, wh
DSI is supported by both mdp4 and mdp5. This patch series adds the common DSI

Currently checkpatch will fuss if one uses world writable
settings in debugfs files and DEVICE_ATTR uses by testing
S_IWUGO but not testing S_IWOTH, S_IRWXUGO or S_IALLUGO.
Extend the check to catch all cases exporting world writable
permissions including octal values.
