[U-Boot] [PATCH v3 0/3] Split rockchip mipi driver into common and specific parts.

[U-Boot] [PATCH v3 0/3] Split rockchip mipi driver into common and specific parts.

[Eric Gao]

This patch series split the rockchip mipi dsi driver into common and
specific parts to make it possible that different soc share the most
common code.


Changes in v2:
-Use dev_read_addr to replace devfdt_get_addr.

Changes in v1:
-Add title.
-Delete the unused variable.

[U-Boot] [PATCH v3 1/3] rockchip: defconfig: Increase max video resolution for mipi panel

[Eric Gao]

The mipi panel used on evb-rk3399 has a 1920x1200 resolution. But now
the max resolution is 1920x1080. So increase it.

[U-Boot] [PATCH v3 2/3] rockchip: video: mipi: Split mipi driver into common and specific parts

[Eric Gao]

To compatible with different rockchip soc, we split the mipi dirver into
common and soc specific parts, and all the soc share the common
functions from common driver part.

[U-Boot] [PATCH v4 2/3] rockchip: video: mipi: Split mipi driver into common and specific parts

[Anatolij Gustschin]

From: "eric.gao@rock-chips.com" <eric.gao@rock-chips.com>

To compatible with different rockchip soc, we split the mipi dirver into
common and soc specific parts, and all the soc share the common
functions from common driver part.
