There are 4 duplicated DPI panel drivers in DSS2 display driver. They are
similar and a generic DPI panel driver can support all them with specific
panel configuration. And new DPI panel driver can be easily supported
by adding panel configurations into generic panel DPI driver.

This patchset introduces a generic panel DPI driver, remove 3 panel drivers and enable
generic panel DPI driver in board files. And it is based on 2.6.37-rc1.

Building with omap2plus_defconfig is successful.

Keep sharp_ls_panel, since it contains blacklight control code which will be
moved out later.

Generic DPI panel driver includes the driver and 4 similar panel configurations. It
will match the panel name which is passed from platform data and setup the
right configurations.

With generic DPI panel driver, we can remove those 4 duplicated panel display
drivers. In the future, it is simple for us just add new panel configuration
date in panel-generic-dpi.c to support new display panel.

This is not right. There may be multiple panels in a single board, and
these would be shared by both of the panels.

What you need to do is have a struct, which contains pointer to the
panel configuration used with that particular dssdev, and set the struct
with dev_set_drvdata().

Check panel-taal.c for an example. There's struct taal_data, which
contains also quite a bit other data, but also a pointer to the panel
config.

Exactly, I just fixed it and sent the updated patchset.

Still keep sharp_ls_panel, since the sharp_ls_panel driver contains blacklight
control driver code which will be moved out later. Then we can use generic DPI
driver for sharp_ls_panel.

* [PATCH 0/3] OMAP: DSS2: introduce generic panel display driver (try #8)

There are 4 duplicated DPI panel drivers in DSS2 display driver. They are
similar and a generic DPI panel driver can support all them with specific
panel configuration. And new DPI panel driver can be easily supported
by adding panel configurations into generic panel DPI driver.

This patchset introduces a generic panel DPI driver, remove 3 panel drivers and enable
generic panel DPI driver in board files. And it is based on 2.6.37-rc2.

Building with omap2plus_defconfig is successful.

Keep sharp_ls_panel, since it contains blacklight control code which will be
moved out later.

Still keep sharp_ls_panel, since the sharp_ls_panel driver contains blacklight
control driver code which will be moved out later. Then we can use generic DPI
driver for sharp_ls_panel.

There are 4 duplicated DPI panel drivers in DSS2 display driver. They are
similar and a generic DPI panel driver can support all them with specific
panel configuration. And new DPI panel driver can be easily supported
by adding panel configurations into generic panel DPI driver.

This patchset introduces a generic panel DPI driver, remove 3 panel drivers and enable
generic panel DPI driver in board files. And it is based on 2.6.37-rc2.

Building with omap2plus_defconfig is successful.

Keep sharp_ls_panel, since it contains blacklight control code which will be
moved out later.

Still keep sharp_ls_panel, since the sharp_ls_panel driver contains blacklight
control driver code which will be moved out later. Then we can use generic DPI
driver for sharp_ls_panel.

There are 4 duplicated DPI panel drivers in DSS2 display driver. They are
similar and a generic DPI panel driver can support all them with specific
panel configuration. And new DPI panel driver can be easily supported
by adding panel configurations into generic panel DPI driver.

This patchset introduces a generic panel DPI driver, remove 3 panel drivers and enable
generic panel DPI driver in board files. And it is based on 2.6.37-rc1.

Building with omap2plus_defconfig is successful.

Keep sharp_ls_panel, since it contains blacklight control code which will be
moved out later.

* [PATCH 2/3] OMAP: use generic DPI panel driver in board files

Still keep sharp_ls_panel, since the sharp_ls_panel driver contains blacklight
control driver code which will be moved out later. Then we can use generic DPI
driver for sharp_ls_panel.

There are 4 duplicated DPI panel drivers in DSS2 display driver. They are
similar and a generic DPI panel driver can support all them with specific
panel configuration. And new DPI panel driver can be easily supported
by adding panel configurations into generic panel DPI driver.

This patchset introduces a generic panel DPI driver, remove 3 panel drivers and enable
generic panel DPI driver in board files. And it is based on 2.6.37-rc1.

Building with omap2plus_defconfig is successful.

Keep sharp_ls_panel, since it contains blacklight control code which will be
moved out later.

Still keep sharp_ls_panel, since the sharp_ls_panel driver contains blacklight
control driver code which will be moved out later. Then we can use generic DPI
driver for sharp_ls_panel.
