sh_mobile_meram: Reset ICBs at unregistration time

2011-09-05T16:37:13+00:00

When ICBs are unregistered and later reused they need to be reset to
avoid data corruption. Set the WBF, WF and RF bits to make sure ICBs get
reset properly.

fbdev: sh_mobile_meram: Remove unneeded sh_mobile_meram.h

2011-08-19T06:22:45+00:00

The drivers/video/sh_mobile_meram.h header contains unused definitions
and declarations. Move the only used macro to sh_mobile_meram.c, and
remove the header.

fbdev: sh_mobile_meram: Fix MExxCTL register save on runtime PM suspend

2011-08-19T06:22:44+00:00

To reset the ICB on resume the MExxCTL register needs to be OR'ed with
MExxCTL_WBF | MExxCTL_WF | MExxCTL_RF, no set to that value. Fix this.

This fixes corruption at the bottom of the display when resuming from
runtime PM.

fbdev: sh_mobile_meram: Validate ICB configuration outside mutex

2011-08-19T06:22:43+00:00

Validate as much of the requested ICB configuration as possible outside
of the mutex-protected region when registering ICBs.

fbdev: sh_mobile_meram: Replace hardcoded register values with macros

2011-08-19T06:22:42+00:00

Instead of hardcoding register values through the driver, define macros
for individual register bits using the register name and the bit name,
and use the macros.

and restored

fbdev: sh_mobile_meram: Move private data from .h to .c

2011-08-19T06:11:16+00:00

There is no reason for sh_mobile_meram_priv to be in the .h file
since it should be private to sh_mobile_meram.c

fbdev: sh_mobile_meram: Correct pointer check for YCbCr chroma plane

2011-06-24T07:40:28+00:00

The check was intended to test if we have a valid pointer to write into,
but it mistakenly checks the pointer contents instead.

Since a valid pointer is mandatory for the chroma data if a YCbCr format
is used, the pointer check has been removed.

sh_mobile_meram: Add support for NV24 framebuffers

2011-05-23T07:06:26+00:00

Since the NV24 framebuffer has a CbCr plane that is twice as wide
as the Y plane, it needs to be handled as a special case.
