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!
