2020-01-06Revert "drm: atmel-hlcdc: enable sys_clk during initalization."Claudiu Beznea1-18/+1
This reverts commit d2c755e66617620b729041c625a6396c81d1231c ("drm: atmel-hlcdc: enable sys_clk during initalization."). With commit "drm: atmel-hlcdc: enable clock before configuring timing engine" there is no need for this patch. Code is also simpler.

2020-01-06drm: atmel-hlcdc: prefer a lower pixel-clock than requestedPeter Rosin1-2/+2
The intention was to only select a higher pixel-clock rate than the requested, if a slight overclocking would result in a rate significantly closer to the requested rate than if the conservative lower pixel-clock rate is selected. The fixed patch has the logic the other way around and actually prefers the higher frequency. Fix that.

2020-01-06drm: atmel-hlcdc: enable clock before configuring timing engineClaudiu Beznea1-1/+7
Changing pixel clock source without having this clock source enabled will block the timing engine and the next operations after (in this case setting ATMEL_HLCDC_CFG(5) settings in atmel_hlcdc_crtc_mode_set_nofb() will fail). It is recomended (although in datasheet this is not present) to actually enabled pixel clock source before doing any changes on timing enginge (only SAM9X60 datasheet specifies that the peripheral clock and pixel clock must be enabled before using LCD controller).

2020-01-02drm/mipi_dbi: Fix off-by-one bugs in mipi_dbi_blank()Geert Uytterhoeven1-2/+2
When configuring the frame memory window, the last column and row numbers are written to the column resp. page address registers. These numbers are thus one less than the actual window width resp. height. While this is handled correctly in mipi_dbi_fb_dirty() since commit 03ceb1c8dfd1e293 ("drm/tinydrm: Fix setting of the column/page end addresses."), it is not in mipi_dbi_blank(). The latter still forgets to subtract one when calculating the most significant bytes of the column and row numbers, thus programming wrong values when the display width or height is a multiple of 256.

2019-12-26drm/sun4i: dsi: Handle bus clock via regmap_mmio_attach_clkJagan Teki1-8/+29
regmap has special API to enable the controller bus clock while initializing register space, and current driver is using devm_regmap_init_mmio_clk which require to specify bus clk_id argument as "bus" But, the usage of clocks are varies between different Allwinner DSI controllers. Clocking in A33 would need bus and mod clocks where as A64 would need only bus clock. Since A64 support only single bus clock, it is optional to specify the clock-names on the controller device tree node. So using NULL on clk_id would get the attached clock. To support clk_id as "bus" and "NULL" during clock enablement between controllers, this patch add generic code to handle the bus clock using regmap_mmio_attach_clk with associated regmap APIs.
