The block also supports TV-out but we leave thatfor another day when we have a hardware using it.We implement parsing and handling of the "port" node,and follow that to the DPI endpoint.The clock divider used by the MCDE to divide down the"lcdclk" (this has been designed for TV-like frequencies)is represented by an ordinary clock provider internallyin the MCDE. This idea was inspired by the PL111 solutionby Eric Anholt: the divider also works very similar tothe Pl111 clock divider.We take care to clear up some errors regarding the numberof available formatters and their type. We have 6 DSIformatters and 2 DPI formatters.Tested on the Samsung GT-I9070 Janice mobile phone.Signed-off-by: Linus Walleij <linus.walleij@linaro.org>Acked-by: Sam Ravnborg <sam@ravnborg.org>Cc: Stephan Gerhold <stephan@gerhold.net>Cc: phone-devel@vger.kernel.orgCc: upstreaming@lists.sr.htLink: https://patchwork.freedesktop.org/patch/msgid/20201112142925.2571179-2-linus.walleij@linaro.org List of files: /linux-6.15/drivers/gpu/drm/mcde/Makefile Thu, 12 Nov 2020 14:29:25 +0000 Linus Walleij <linus.walleij@linaro.org> http://172.16.0.5:8080/history/linux-6.15/drivers/gpu/drm/mcde/Makefile#5fc537bf drm/mcde: Add new driver for ST-Ericsson MCDEThis adds a new DRM driver for the ST-Ericsson Multi ChannelDisplay Engine, MCDE display controller.This hardware has three independent DSI hosts and can compositand display several memory buffers onto an LCD display. Itwas developed for several years inside of ST-Ericsson andshipped with a few million mobile phones from Sony and Samsung,as well as with the Snowball community development board.The driver is currently pretty rudimentary but supports asimple framebuffer so we can get penguins and graphics whenusing these SoCs.Acked-by: Daniel Vetter <daniel.vetter@ffwll.ch>Signed-off-by: Linus Walleij <linus.walleij@linaro.org>Link: https://patchwork.freedesktop.org/patch/msgid/20190524092019.19355-1-linus.walleij@linaro.org List of files: /linux-6.15/drivers/gpu/drm/mcde/Makefile Fri, 24 May 2019 09:20:19 +0000 Linus Walleij <linus.walleij@linaro.org>
