2023-05-30drm/panel-edp: Convert to platform remove callback returning voidUwe Kleine-König1-6/+4
The .remove() callback for a platform driver returns an int which makes many driver authors wrongly assume it's possible to do error handling by returning an error code. However the value returned is (mostly) ignored and this typically results in resource leaks. To improve here there is a quest to make the remove callback return void. In the first step of this quest all drivers are converted to .remove_new() which already returns void. panel_edp_remove() always returned zero, so convert it to return void without any loss and then just drop the return from panel_edp_platform_remove().

2023-05-30dt-bindings: bridge: samsung-dsim: Make some flags optionalAdam Ford1-4/+5
In the event a device is connected to the samsung-dsim controller that doesn't support the burst-clock, the driver is able to get the requested pixel clock from the attached device or bridge. In these instances, the samsung,burst-clock-frequency isn't needed, so remove it from the required list. The pll-clock frequency can be set by the device tree entry for samsung,pll-clock-frequency, but in some cases, the pll-clock may have the same clock rate as sclk_mipi clock. If they are equal, this flag is not needed since the driver will use the sclk_mipi rate as a fallback.

2023-05-26drm: bridge: samsung-dsim: Support non-burst modeAdam Ford1-6/+19
The high-speed clock is hard-coded to the burst-clock frequency specified in the device tree. However, when using devices like certain bridge chips without burst mode and varying resolutions and refresh rates, it may be necessary to set the high-speed clock dynamically based on the desired pixel clock for the connected device. This also removes the need to set a clock speed from the device tree for non-burst mode operation, since the pixel clock rate is the rate requested from the attached device like a bridge chip. This should have no impact for people using burst-mode and setting the burst clock rate is still required for those users. If the burst clock is not present, change the error message to dev_info indicating the clock use the pixel clock.

2023-05-26drm: bridge: samsung-dsim: Fix PMS Calculator on imx8m[mnp]Adam Ford2-2/+23
According to Table 13-45 of the i.MX8M Mini Reference Manual, the min and max values for M and the frequency range for the VCO_out calculator were incorrect. This information was contradicted in other parts of the mini, nano and plus manuals. After reaching out to my NXP Rep, when confronting him about discrepencies in the Nano manual, he responded with: "Yes it is definitely wrong, the one that is part of the NOTE in MIPI_DPHY_M_PLLPMS register table against PMS_P, PMS_M and PMS_S is not correct. I will report this to Doc team, the one customer should be take into account is the Table 13-40 DPHY PLL Parameters and the Note above." These updated values also match what is used in the NXP downstream kernel. To fix this, make new variables to hold the min and max values of m and the minimum value of VCO_out, and update the PMS calculator to use these new variables instead of using hard-coded values to keep the backwards compatibility with other parts using this driver.

2023-05-25drm/bridge: ti-sn65dsi83: Fix enable/disable flow to meet specFrieder Schrempf1-3/+16
The datasheet describes the following initialization flow including minimum delay times between each step: 1. DSI data lanes need to be in LP-11 and the clock lane in HS mode 2. toggle EN signal 3. initialize registers 4. enable PLL 5. soft reset 6. enable DSI stream 7. check error status register To meet this requirement we need to make sure the host bridge's pre_enable() is called first by using the pre_enable_prev_first flag. Furthermore we need to split enable() into pre_enable() which covers steps 2-5 from above and enable() which covers step 7 and is called after the host bridge's enable().

2023-05-25drm: bridge: samsung-dsim: Fix i.MX8M enable flow to meet specFrieder Schrempf1-2/+23
According to the documentation [1] the proper enable flow is: 1. Enable DSI link and keep data lanes in LP-11 (stop state) 2. Disable stop state to bring data lanes into HS mode Currently we do this all at once within enable(), which doesn't allow to meet the requirements of some downstream bridges. To fix this we now enable the DSI in pre_enable() and force it into stop state using the FORCE_STOP_STATE bit in the ESCMODE register until enable() is called where we reset the bit. We currently do this only for i.MX8M as Exynos uses a different init flow where samsung_dsim_init() is called from samsung_dsim_host_transfer().

2023-05-23drm/bridge: anx7625: Prevent endless probe loopNícolas F. R. A. Prado1-40/+88
During probe, the driver registers i2c dummy devices and populates the aux bus, which registers a device for the panel. After doing that, the driver can still defer probe if needed. This ordering of operations is troublesome however, because the deferred probe work will retry probing all pending devices every time a new device is registered. Therefore, if modules need to be loaded in order to satisfy the dependencies for this driver to complete probe, the kernel will stall, since it'll keep trying to probe the anx7625 driver, but never succeed, given that modules would only be loaded after the deferred probe work completes. Two changes are required to avoid this issue: * Move of_find_mipi_dsi_host_by_node(), which can defer probe, to before anx7625_register_i2c_dummy_clients() and devm_of_dp_aux_populate_ep_devices(), which register devices. * Make use of the done_probing callback when populating the aux bus, so that the bridge registration is only done after the panel is probed. This is required because the panel might need to defer probe, but the aux bus population needs the i2c dummy devices working, so this call couldn't just be moved to an earlier point in probe. One caveat is that if the panel is described outside the aux bus, the probe loop issue can still happen, but we don't have a way to avoid it in that case since there's no callback available. With this patch applied, it's possible to boot on mt8192-asurada-spherion with CONFIG_DRM_ANALOGIX_ANX7625=y CONFIG_MTK_MMSYS=m CONFIG_BACKLIGHT_PWM=y and also with CONFIG_DRM_ANALOGIX_ANX7625=y CONFIG_MTK_MMSYS=y CONFIG_BACKLIGHT_PWM=m Fixes: adca62ec370c ("drm/bridge: anx7625: Support reading edid through aux channel") Fixes: 269332997a16 ("drm/bridge: anx7625: Return -EPROBE_DEFER if the dsi host was not found") Reported-by: "kernelci.org bot" <bot@kernelci.org> Signed-off-by: Nícolas F.
