Character LCD driver for the Hitachi HD44780 with I2C connection: There already is a driver for displays with parallel gpio connections. Re-uses the high-level API.
Concerning the compatible-string: I'm currently using "hit,hd44780+nxp,pcf8575" - "hit,hd44780" is used for the parallel-connected version of the display - nxp,pcf8575 already exists in drivers/gpio/gpio-pcf857x.c which uses the same chip for gpio expansion. Let me know if this choice of names is fine or should be changed. For the other device-tree names I'm reusing (some of) the names from the parallel connected display. .../auxdisplay/hit,hd44780+nxp,pcf8575.yaml (new) | 65 +++++++ drivers/auxdisplay/Kconfig | 14 +- drivers/auxdisplay/Makefile | 1 + drivers/auxdisplay/hd44780-pcf8574.c (new) | 207 +++++++++++++++++++++ 4 files changed, 286 insertions(+), 1 deletion(-) -- Ralf Schlatterbeck Tel: +43/2243/26465-16 Open Source Consulting www: www.runtux.com Reichergasse 131, A-3411 Weidling email: off...@runtux.com
