Not all platforms has P0 at an offset of 0x1000 from the base address, so add support for specifying each sub-region in DT. The code falls back to the predefined offsets in the case that only a single reg is specified, in order to support existing DT. Reviewed-by:

Not all platforms has DP_P0 at offset 0x1000 from the beginning of the DP block. So split the dss_io_data memory region into a set of sub-regions, to make it possible in the next patch to specify each of the sub-regions individually. Reviewed-by:

In order to deal with multiple memory ranges in the following commit change the ioremap wrapper to not poke directly into the dss_io_data struct. While at it, devm_ioremap_resource() already prints useful error messages on failure, so omit the unnecessary prints from the caller. Signed-off-by:

Bjorn Andersson authored
The non-devres version of ioremap is used, which requires manual cleanup. But the code paths leading here is mixed with other devres users, so rely on this for ioremap as well to simplify the code. Reviewed-by:

Bjorn Andersson authored
reg was defined as one region covering the entire DP block, but the memory map is actually split in 4 regions and obviously the size of these regions differs between platforms. Switch the reg to require that all four regions are specified instead. It is expected that the implementation will handle existing DTBs, even though the schema defines the new layout. Reviewed-by:

The DSI host might be left in some state by the bootloader. If this state generates an IRQ, it might hang the system by holding the interrupt line before the driver sets up the DSI host to the known state. Move the request_irq into msm_dsi_host_init and pass IRQF_NO_AUTOEN to it. Call enable/disable_irq after msm_dsi_host_power_on/_off() functions, so that we can be sure that the interrupt is delivered when the host is in the known state. It is not possible to defer the interrupt enablement to a later point, because drm_panel_prepare might need to communicate with the panel over the DSI link and that requires working interrupt.

For now, since we have a mix of bridges which support this flag, which which do *not* support this flag, or work both ways, try it once with NO_CONNECTOR and then fall back to the old way if that doesn't work.

[why] vsync_cnt atomic counter increments for every hw vsync. On the other hand, frame count is a register that increments when the frame gets actually pushed out. We cannnot read this register whenever the timing engine is off, but vblank counter should still return a valid number. This behavior also matches the downstream driver. [How] Read the encoder vsync count instead of the dpu_encoder_phys frame count. Suggested-by:

The downstream driver models this PLL lock check as an if-elseif-else. The only way to reach the else case where pll_locked=true [1] is by succeeding both readl_poll_timeout_atomic calls (which return zero on success) in the if _and_ elseif condition. Hence both the "lock" and "ready" bit need to be tested in the SM_READY_STATUS register before considering the PLL locked and ready to go. Tested on the Sony Xperia XA2 Ultra (nile-discovery, sdm630).

The commit 9f91f22a ("drm/msm/dsi: remove duplicate fields from dsi_pll_Nnm instances") mistakenly changed registered clock names. While the platform is in progress of migration to using clock properties in the dts rather than the global clock names, we should provide backwards compatibility. Thus restore registerd global clock names. Fixes: 9f91f22a ("drm/msm/dsi: remove duplicate fields from dsi_pll_Nnm instances") Signed-off-by:
