The field mode_valid in exynos_drm_crtc_ops is expected to be of type enum drm_mode_status (*mode_valid)(struct exynos_drm_crtc *crtc, const struct drm_display_mode *mode); Likewise for mode_valid in drm_connector_helper_funcs. The mismatched return type breaks forward edge kCFI since the underlying function definition does not match the function hook definition. The return type of mixer_mode_valid and hdmi_mode_valid should be changed from int to enum drm_mode_status.

Once EDID is parsed, the monitor HDMI support information is available through drm_display_info.is_hdmi. This driver calls drm_detect_hdmi_monitor() to receive the same information, which is less efficient. Avoid calling drm_detect_hdmi_monitor() and use drm_display_info.is_hdmi instead. Signed-off-by:

On MSM8996 the HDMI PHY provides the PLL clock to the MMCC. As we are preparing to convert the MSM8996 to use DT clocks properties (rather than global clock names), register the OF clock provider. While we are at it, also change the driver to use clk_parent_data rather parent_names to setup a link to the XO clock. Signed-off-by:

Currently the DSI driver has two separate paths: one if the next device in a chain is a bridge and another one if the panel is connected directly to the DSI host. Simplify the code path by using panel-bridge driver (already selected in Kconfig) and dropping support for handling the panel directly. Signed-off-by:

The commit 0f40ba48 ("drm/msm/dsi: Pass DSC params to drm_panel") added a pointer to the DSC data to the struct drm_panel. However DSC support is not limited to the DSI panels.

The dsi_phy_driver_probe() function has a "goto fail" for no reason. Change it to just always return directly when it sees an error. Make this simpler by leveraging dev_err_probe() which is designed to make code like this shorter / simpler. NOTE: as part of this, we now pass through error codes directly from msm_ioremap_size() rather than translating to -ENOMEM. This changed mostly because it's much more convenient when using dev_err_probe() and also it's usually encouraged not to hide error codes like the old code was doing unless there is a good reason. I can't see any reason why we'd need to return -ENOMEM instead of -EINVAL from the probe function. Signed-off-by:

As of the commit 1de452a0 ("regulator: core: Allow drivers to define their init data as const") we no longer need to do copying of regulator bulk data from initdata to something dynamic. Let's take advantage of that. In addition to saving some code, this also moves us to using ARRAY_SIZE() to specify how many regulators we have which is less error prone. This gets rid of some layers of wrappers which makes it obvious that we can get rid of an extra error print. devm_regulator_bulk_get_const() prints errors for you so you don't need an extra layer of printing. In all cases here I have preserved the old settings without any investigation about whether the loads being set are sensible. In the cases of some of the PHYs if several PHYs in the same file used exactly the same settings I had them point to the same data structure. NOTE: Though I haven't done the math, this is likely an overall savings in terms of "static const" data. We previously always allocated space for 8 supplies. Each of these supplies took up 36 bytes of data (32 for name, 4 for an int). Signed-off-by:

As of commit 6eabfc01 ("regulator: core: Allow specifying an initial load w/ the bulk API") we can now specify the initial load in the bulk data rather than having to manually call regulator_set_load() on each regulator. Let's use it. Signed-off-by:
-
Douglas Anderson authored
As of commit 5451781d ("regulator: core: Only count load for enabled consumers"), a load isn't counted for a disabled regulator. That means all the code in the DSI driver to specify and set loads before disabling a regulator is not actually doing anything useful. Let's remove it. It should be noted that all of the loads set that were being specified were pointless noise anyway. The only use for this number is to pick between low power and high power modes of regulators. Regulators appear to do this changeover at loads on the order of 10000 uA. You would need a lot of clients of the same rail for that 100 uA number to count for anything. Note that now that we get rid of the setting of the load at disable time, we can just set the load once when we first get the regulator and then forget it. It should also be noted that the regulator functions regulator_bulk_enable() and regulator_set_load() already print error messages when they encounter problems so while moving things around we get rid of some extra error prints.

The clock names formatted into the hw_clk's init structure are only used for the duration of the registration function where they are kstrdup'ed, making it unnecessary to keep the allocations alive for the duration of the device (through devm).

The commit 613cbd1d ("drm/msm/dsi: use devm_clk_*register to registe DSI PHY clocks") introduced the devm_ prefix to clk_hw registration calls, without updating the indentation of the arguments on the following lines. Similarly commit e55b3fbb ("drm/msm/dsi: drop PLL accessor functions") moved from pll_write to dsi_phy_write without updating the indentation of followup arguments either. Preparing for a series that heavily touches the clk calls, reflow and reindent function calls that are adhering to an 80-char column limit by spanning multiple lines. Where function names are very long the arguments are indented with a fixed number of two tab characters instead of aligning with the opening parenthesis of the function call. Signed-off-by:
