This is a 128x128 1.4" TFT display driven by a Sitronix ST7715R TFT Controller/Driver. It is used on the "lcd-pmod" display module that is shipped with Renesas RSK+RZA1 development boards, and with several other Renesas starter kits, for RX, Synergy, and RZ/T1 MCUs and SoCs. I'm not 100% sure about the actual Okaya part number, but this is the only display listed on the Okaya website that matches the specifications. Patch 2 depends on "[PATCH] drm/mipi_dbi: Fix off-by-one bugs in mipi_dbi_blank()"[1], which I sent earlier this week. This has been tested using the r7s72100-rskrza1-pmod-spi.dtso and r7s72100-rskrza1-pmod2-lcd.dtso DT overlays[2]. Note that for using this on RSK+RZA1, there is a dependency on RSPI cs-gpios support[3]. With DT overlays, this also depends on DT overlays[4] and gpio-hog overlay support[5]. Thanks for your comments!
