Balaji T K fc7b92fca4 mfd: Rename all twl4030_i2c*
This patch renames function names like twl4030_i2c_write_u8,
twl4030_i2c_read_u8 to twl_i2c_write_u8, twl_i2c_read_u8
and also common variable in twl-core.c

Santosh Shilimkar b07682b605 mfd: Rename twl4030* driver files to enable re-use
The upcoming TWL6030 is companion chip for OMAP4 like the current TWL4030
for OMAP3. The common modules like RTC, Regulator creates opportunity
to re-use the most of the code from twl4030.

This patch renames few common drivers twl4030* files to twl* to enable
the code re-use.

Michael Hennerich c24b6b6a8e backlight: adp5520: rename common defines and typos
The common adp5520 mfd defines were namespaced to avoid collisions, so
update the define used in this driver accordingly.  The structs were also
renamed to fix a spelling typo.

Tomi Valkeinen 640f9ca5fd OMAP: Add support for VRFB rotation engine
VRFB rotation engine is a block in OMAP2/3 that offers 12 independent
contexts that can be used for framebuffer rotation.

Each context has a backend area of real memory, where it stores the
pixels in undisclosed format. This memory is offered to users via 4
virtual memory areas, which see the same memory area in different
rotation angles (0, 90, 180 and 270 degrees).

Tomi Valkeinen afedec183e OMAP: Add VRAM manager
Add a Video RAM manager for OMAP 2 and 3 platforms. VRAM manager is used
to allocate large continuous blocks of SDRAM or SRAM. The features VRAM
manager has that are missing from dma_alloc_* functions are:

- Support for OMAP2's SRAM
- Allocate without ioremapping
- Allocate at defined physical addresses
- Allows larger VRAM area and larger allocations

The upcoming DSS2 uses VRAM manager.

VRAM area size can be defined in kernel config, board file or with
kernel boot parameters. Board file definition overrides kernel config,
and boot parameter overrides kernel config and board file.

The upcoming new display subsystem driver is divided to two devices,

This patch adds a dummy omapdss platform device for the current omapfb
driver, which is then used to get the clocks. This will make it possible
for the current and the new display drivers to co-exist.

Konrad Rzeszutek Wilk df11303c90 xen pvfb: Inhibit VM_IO flag to be set on vmalloc-ed framebuffers.
In Xen-paravirt mode, VM_IO flag signifies that the page frame number (PFN)
is actually a machine frame number (MFN). This is correct for memory backed by
PCI devices, but wrong for memory allocated from System RAM where the PFN
!= MFN.

During page faults, pages with VM_IO, get assigned to special domain I/O
domain and as said, the PFN is interpreted as MFN. When Xen hypervisor
modifies the PTE it interprets the PFN as the MFN, complains and
fails the PTE modification.

The end result is an infinitive page fault in the domain.

Konrad Rzeszutek Wilk a9b5ff99c3 fb-defio: Inhibit VM_IO flag to be set on vmalloc-ed framebuffers.
The framebuffers (screenbase) these drivers present are actually
vmalloc-ed pages. There is no need for them to have the VM_IO flag set.

Konrad Rzeszutek Wilk 7164bb4393 fb-defio: If FBINFO_VIRTFB is defined, do not set VM_IO flag.
Most users (except sh_mobile_lcdcfb.c) get their framebuffer from
vmalloc. Setting VM_IO is not necessary as the memory obtained
from vmalloc is System RAM type and is not susceptible to PCI memory
constraints.

Julia Lawall 0fdd07f77f VIDEO: Correct use of request_region/request_mem_region
request_region should be used with release_region, not request_mem_region.

Geert Uytterhoeven pointed out that in the case of drivers/video/gbefb.c,
the problem is actually the other way around; request_mem_region should be
used instead of request_region.

The semantic patch that finds/fixes this problem is as follows:
(http://coccinelle.lip6.fr/)

// <smpl>

request_region(start,...)

- release_mem_region

Sudhakar Rajashekhara 3510b8f7f5 davinci: fb: fix frame buffer driver issues
Following issues have been addressed on DA8XX/OMAP-L1XX:

a. Screen misalignment during booting when frame buffer console is
   enabled.

b. Driver was configured always in PSEUDOCOLOR mode.  This patch
   dynamically configures the driver either in PSEUDOCOLOUR or TRUECOLOR
   mode depending on bpp.

c. The RED and BLUE offsets were interchanged resulting in wrong
   bootup logo colour.

This patch has been tested on DA830/OMAP-L137 and DA850/OMAP-L138 EVMs.

Mike Rapoport f64dcac0b1 backlight: tdo24m: ensure chip select changes between transfers
Some SPI host drivers do not change chip select betwen transfers unless
.cs_chnage field is explicitly set. The LCD spec requires chip select
change between consecuitive transfers, so ensure it at the SPI driver
level.

Sven Neumann 448ac47976 pxafb: use passed fb_var_screeninfo struct in pxafb_pan_display()
pxafb_pan_display() used to ignore the fb_var_screeninfo parameter. Now
pass it to setup_base_frame() instead of pulling default values out of
fb_info.

And the original patch has an issue of pxafb_pan_display() paying only
attention to the 'var' parameter passed in, and Ville Syrjälä pointed
out, this is potentially dangerous as user could pass in any other
screeninfo parameters as well, and not only such that are relevant for
display panning. This is fixed by limiting the arguments actually used
to .xoffset, .yoffset and .vmode & FB_VMODE_YWRAP.
