Subject: [PATCH v2 0/5] drm: Add support for Okaya RH128128T

	Hi all,

This patch series adds support for the Okaya RH128128T LCD to the
existing ST7735R driver.  This is a 128x128 1.4" TFT display driven by a
Sitronix ST7715R TFT Controller/Driver.  It is used on e.g. the Renesas
YRSK-LCD-PMOD extension board, which is shipped with Renesas RSK+RZA1
development boards[1], and with several other Renesas starter kits, for
RX, Synergy, and RZ/T1 MCUs and SoCs.

Changes compared to v1[2]:
  - Convert DT bindings to DT schema,
  - Add YRSK-LCD-PMOD reference and links,
  - Add Reviewed-by,
  - Split driver preparation and adding actual support in two separate
    patches,
  - Replace st7735r_priv.rgb by a pointer to struct st7735r_cfg,
  - Change prefix of jd_t18003_t01_pipe_enable() and
    jd_t18003_t01_pipe_funcs(),
  - Update Kconfig help text,
  - Improve file comment header.

This has been tested using the r7s72100-rskrza1-pmod-spi.dtso and
r7s72100-rskrza1-pmod2-lcd.dtso DT overlays[3].
Note that for using this on RSK+RZA1, there is a dependency on RSPI
cs-gpios support (now in linux-next).
With DT overlays, this also depends on DT overlays[4] and gpio-hog
overlay support[5].

Thanks!
