When the cursor position gets to the end of the LCD console we normally scroll by one line. This adds an option to increase that value. Console scrolling is often slow, and if a large amount of output is being sent, increasing this option to 10 or so will speed things up considerably. Signed-off-by:

Add support for selecting the required cache mode for the LCD: off, write-through or write-back. Signed-off-by:

For tegra we want to enable the cache for the LCD. This is easier if we can avoid using L2 page tages, so align the LCD to a section boundary. Signed-off-by:

This provides an option for the LCD to flush the dcache after each update (puts, scroll or clear). Signed-off-by:

The normal alignment is PAGE_SIZE, but if this is defined, we can support other alignments. The motivation for this change is to make the display section-aligned on ARM so that we can easily turn off data caching for the frame buffer region without resorting to level 2 page tables. Signed-off-by:

Add support for adjusting the L1 cache behavior by updating the MMU configuration. The mmu_set_region_dcache_behaviour() function allows drivers to make these changes after the MMU is set up. It is implemented only for ARMv7 at present. This is needed for LCD support, where we want to make the LCD frame buffer write-through (or off) rather than write-back. Signed-off-by:

Add LCD definitions and also a proposed binding for LCD displays. The PWM is as per what will likely be committed to linux-next soon. The displaymode binding comes from a proposal here: http://lists.freedesktop.org/archives/dri-devel/2012-July/024875.html The panel binding is new, and fills a need to specify the panel timings and other tegra-specific information. Should a binding appear that allows the pwm to handle this automatically, we can revisit this. Signed-off-by:

This binding will apparently soon be in linux-next. Bring it in now since we need to do something, and may as well try to target what Linux will have. Signed-off-by:

These platforms don't include dcache support. Define CONFIG_SYS_DCACHE_OFF so that functions don't try to call non-existent routines like flush_dcache_range(). Signed-off-by:
