Thanks, it's been a while since I looked at this so I had forgotten to update the comment. Now done.
if (resource_size(r) > SZ_4K)
mem = r;
nit again: The register address window of Dove LCD is 64k although you are right an no more than 512B are used. Also a comment would be nice, that everything above 4k (64k) is interpreted as gfx mem.
Fixed and comment added.
- /* Create all LCD controllers */
- for (n = 0; n < ARRAY_SIZE(priv->dcrtc); n++) {
struct clk *clk;
if (!res[n])
break;
clk = clk_get_sys("dovefb.0", "extclk");
To be precise: the above should have the index at extclk as there is two extclk inputs that can be used for both lcdcs. So currently, as armada_crtc is hard-coding extclk0 input it should be "armadafb.%d", "extclk0".
But I know, clocking in general will work-out with parent select for clk-mux and DT support.
I've sorted that out, but I'd forgotten there were three additional patches on top of what I've posted sorting that stuff out - the second one in particular:
4a5e9b7 DRM: armada: store kernel address for gem objects f760c94 DRM: Dove: alternative variant based clocking 2e051fd DRM: Armada: convert hardware cursor support to 64x32 or 32x64 ARGB
Because they're scattered in other branches (the h/w cursor stuff is separate) it's not trivial to generate a single series from git for these.
+static const struct armada_output_type armada_drm_conn_slave = {
- .connector_type = DRM_MODE_CONNECTOR_HDMIA,
For a rework of DRM slave encoder API, there should also be some way to get .connector_type and .encoder_type above from that slave encoder. IMHO it should be up to the slave encoder to determine connector and encoder type.
Encoder type - yes, but connector type doesn't seem sensible. It's possible for the TDA998x to be connected to a DVI connector - how would the slave encoder know that?
