The probe function is highly adapted to the RK3288 specificities, move all specific bits into an "rk3288_probe" function, also part of the platform data. The goal is to ease the addition of new flavors of Rockchip LVDS IPs. Signed-off-by:

Prepare the introduction of PX30 support by using drm_encoder_helper_funcs as platform data instead of multiple register names which are specific to rk3288 and not generic to all Rockchip IPs. This way adding support for a new flavor of a similar IP will be a matter of adding the relevant helper funcs. Signed-off-by:

Prepare the introduction of PX30 support by clarifying the function prefixes. We continue to prefix with 'rockchip_lvds_' generic functions that are not specific to a single hardware. Functions implying hardware modifications are now prefixed with 'rk3288_lvds_'. Signed-off-by:

In the probe function, some resources are allocated using 'dma_alloc_wc()', they should be released with 'dma_free_wc()', not 'dma_free_coherent()'. We already use 'dma_free_wc()' in the remove function, but not in the error handling path of the probe function. Also, remove a useless 'PAGE_ALIGN()'. 'info->fix.smem_len' is already PAGE_ALIGNed.

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 03ceb1c8 ("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.

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.

As per the user manual, look like mod clock is not mandatory for all Allwinner MIPI DSI controllers, it is connected to CLK_DSI_SCLK for A31 and not available in A64. So, add compatible check for A31 and get mod clock accordingly. Tested-by:

Jagan Teki authored
The MIPI DSI controller in Allwinner A64 is similar to A33. But unlike A33, A64 doesn't have DSI_SCLK gating so it is valid to have separate compatible for A64 on the same driver. DSI_SCLK uses mod clock-names on dt-bindings, so the same is not required for A64. On that note - A64 require minimum of 1 clock like the bus clock - A33 require minimum of 2 clocks like both bus, mod clocks So, update dt-bindings so-that it can document both A33, A64 bindings requirements.
