Subject: [PATCH 0/3] drm: Add support for Okaya RH128128T
Date: Thu, 2 Jan 2020 15:12:43 +0100 [thread overview]
Message-ID: <20200102141246.370-1-geert+renesas@glider.be> (raw)
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 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!
