Subject: [PATCH v2 0/4] drm/ssd130x: Add support for SINO WEALTH SH1106

From: Chen-Yu Tsai <wens@...e.org>

Hi everyone,

This series adds support for SH1106 to the ssd130x OLED display
driver.

Changes since v1:

- Fixed ordering of SINO WEALTH in vendor prefix list

- Updated allOf:if: blocks in DT binding, i.e. added default values for
  solomon,dclk-{div,frq}

- Added SSD130X_PAGE_COL_START_{HIGH,LOW}_SET and used that to set the
  bitfields for the two commands.
  I didn't feel SSD130X_PAGE_COL_START_{HIGH,LOW}_MASK was needed, as
  it was the same between both commands.

- Added SH110x to the SSD130X Kconfig help texts
  There are SH110[789] as well, but they don't seem to be easy to find.


The SINO WEALTH SH1106 is an OLED display driver that is somewhat
compatible with the SSD1306. It supports a slightly wider display,
at 132 instead of 128 pixels. The basic commands are the same, but
the SH1106 doesn't support the horizontal or vertical address modes.

This driver chip is found in some cheap 1.3" OLED panel modules. It
acts as a substitute for the SSD1306.

Patch 1 adds an entry to the vendor prefixes for SINO WEALTH
Eletronics Ltd.

Patch 2 adds an entry for SH1106 to the ssd1307fb binding.

Patch 3 adds support for the base "page addressing mode" to the ssd130x
driver.

Patch 4 adds support for the SH1106 to the ssd130x driver.

Please have a look.


Thanks
ChenYu
