2024-04-04drm/bridge: adv7511: Allow IRQ to share GPIO pinsAdam Ford
The IRQ registration currently assumes that the GPIO is dedicated to it, but that may not necessarily be the case. If the board has another device sharing the GPIO, it won't be registered and the hot-plug detect fails to function. Currently, the handler reads two registers and blindly assumes one of them caused the interrupt and returns IRQ_HANDLED unless there is an error. In order to properly do this, the IRQ handler needs to check if it needs to handle the IRQ and return IRQ_NONE if there is nothing to handle. With the check added and the return code properly indicating whether or not it there was an IRQ, the IRQF_SHARED can be set to share a GPIO IRQ. V2: Add check to see if there is IRQ data to handle Signed-off-by: Adam Ford <aford173@gmail.com> Reviewed-by: Laurent Pinchart <laurent.pinchart+renesas@ideasonboard.com> Reviewed-by: Dmitry Baryshkov <dmitry.baryshkov@linaro.org> Signed-off-by: Dmitry Baryshkov <dmitry.baryshkov@linaro.org> Link: https://patchwork.freedesktop.org/patch/msgid/20240305004859.201085-1-aford173@gmail.com Signed-off-by: Dmitry Baryshkov <dmitry.baryshkov@linaro.org>

Most of our helpers have relied on being selected so far through Kconfig, but that creates issues when we have multiple layers of helpers with some depending on others.

Commit 00084f0c01bf ("drm: bridge: thc63lvd1024: Switch to use of_graph_get_remote_node()") simplified the thc63lvd1024 driver by replacing hand-rolled code with a helper function.

2024-03-18drm/bridge: ite66121: Register HPD interrupt handler only when 'client->irq > 0'Sui Jingfeng
If a specific design doesn't wire IT66121's interrupt signal output pin up to the display controller side, then we should not register the interrupt handler. Such a decision is valid usage, as we can fall back to polling mode. So, don't make the assumption that a specific board always supports HPD. Carry out a sanity check on 'client->irq' before using it, fall back to polling mode if client->irq < 0 is true. Such a design increases the overall flexibility.

2024-02-23drm/bridge: aux-hpd: separate allocation and registrationJohan Hovold
Combining allocation and registration is an anti-pattern that should be avoided. Add two new functions for allocating and registering an dp-hpd bridge with a proper 'devm' prefix so that it is clear that these are device managed interfaces. devm_drm_dp_hpd_bridge_alloc() devm_drm_dp_hpd_bridge_add() The new interface will be used to fix a use-after-free bug in the Qualcomm PMIC GLINK driver and may prevent similar issues from being introduced elsewhere. The existing drm_dp_hpd_bridge_register() is reimplemented using the above and left in place for now.

Apart from the two of_xlate implementations this member is write-only. In the of_xlate functions of_pwm_xlate_with_flags() and of_pwm_single_xlate() it's more sensible to check for args->args_count because this is what is actually used in the device tree.
