| ea34d5a | Phil Elwell | 30 May 2024, 14:59:52 UTC | ARM: dts: Move rpi-otp nodes onto a dedicated bus The rpi-otp driver uses a virtualised, OTP-relative addressing scheme. However, when instance nodes are children of "/soc" they appear to be addressable directly by the host, which is wrong (but not in a way which causes an error unless one goes looking for one). Add a wrapper (bus) node without a "ranges" property to make the separation clear.

The intention here was to use the cell values, but the embedded "0" was not removed as it should have been. The implication of this mistake is that inverted sync flags would be ignored because the 0 value corresponds to GPIO_ACTIVE_HIGH. The extra cell value would be treated as the start of another override, but then ignored because the end of the parameter is reached. These errors should have been picked up by the automated checks, but the base dts files weren't subjected to the same validation. This has now been corrected.

This FIFO has an edge case where it can drop QoS for a request to 0 if there's a single outstanding read request in the FIFO, and another is pushed when the FIFO is popped. Requests with a QoS of 0 can take hundreds of microseconds to complete. By adding an experimentally-determined amount of backpressure on the pop side, the critical level transition can largely be avoided.

Until now after a bcm2835 pin was freed its pinmux was set to GPIO_IN. So in case it was configured as GPIO_OUT before the configured output level also get lost. As long as GPIO sysfs was used this wasn't actually a problem because the pins and their possible output level were kept by sysfs. Since more and more Raspberry Pi users start using libgpiod they are confused about this behavior. So make the pin freeing behavior of GPIO_OUT configurable via module parameter. In case pinctrl-bcm2835.persist_gpio_outputs is set to 1, the output level is kept. This patch based on the downstream work of Phil Elwell.

| fef4179 | Dave Stevenson | 01 February 2022, 12:20:20 UTC | drm/panel: Add and initialise an orientation field to drm_panel from OF "rotation" is listed as a standard property of panels in panel-common.yaml, therefore it would be logical to process that from within the core code should a panel driver not implement the get_orientation hook. Call of_drm_get_panel_orientation from drm_connector_set_orientation_from_panel to get that information. This removes the need for any boiler-plate in panel drivers for calling drm_connector_set_orientation_from_panel or drm_connector_set_panel_orientation.

| ab273ed | Nick Hollinghurst | 22 April 2024, 12:06:21 UTC | DRM: rp1: rp1-dsi: Fix escape clock divider and timeouts. Escape clock divider was fixed at 5, which is correct at 800Mbps/lane but increasingly out of spec for higher rates. Compute it correctly. High speed timeout was fixed at 5*512 == 2560 byte-clocks per lane. Compute it conservatively to be 8/7 times the line period (assuming there will be a transition to LP some time during each scanline?) keeping the old value as a lower bound. Increase LPRX TO to 1024, and BTA TO to 0xb00 (same value as in bridge/synopsys/dw-mipi-dsi). (No change to LP_CMD_TIM. To do: compute this correctly.)

| c7b270a | Dom Cobley | 23 April 2024, 16:30:56 UTC | vc4/hdmi: Ignore hotplug interrupt with force_hotplug The intention of the vc4.force_hotplug setting is to ignore hotplug completely. It can be used when a display toggles hotplug when switching AV inputs, going into standby or changing a KVM switch, and some side effect of that is unwanted. It turns out while vc4.force_hotplug currently makes hotplug always read as asserted, that isn't enough to stop drm doing lots of stuff, including re-reading the edid. An example of what drm does with a hotplug deasert/assert and vc4.force_hotplug=1 currently is: https://paste.debian.net/hidden/dc07434b/ That is unwanted. Lets ignore the hotplug interrupt completely so drm is blissfully unaware of the hotplug change. Signed-off-by: Dom Cobley <popcornmix@gmail.com> | 03 June 2024, 17:49:16 UTC |
