drm/exynos: Search for TE-gpio in DSI panel's node

2022-02-25T00:50:48+00:00

TE-gpio, if defined, is placed in the panel's node, not the parent DSI
node. Change the devm_gpiod_get_optional() to gpiod_get_optional() and
pass proper device node to it. The code already has a proper cleanup
path, so it looks that the devm_* variant has been applied accidentally
during the conversion to gpiod API.

drm/exynos: Don't fail if no TE-gpio is defined for DSI driver

2022-02-25T00:50:47+00:00

TE-gpio is optional and if it is not found then gpiod_get_optional()
returns NULL. In such case the code will continue and try to convert NULL
gpiod to irq what in turn fails. The failure is then propagated and driver
is not registered.

Fix this by returning early from exynos_dsi_register_te_irq() if no
TE-gpio is found.

drm/exynos: gsc: Use platform_get_irq() to get the interrupt

2022-02-25T00:50:47+00:00

platform_get_resource(pdev, IORESOURCE_IRQ, ..) relies on static
allocation of IRQ resources in DT core code, this causes an issue
when using hierarchical interrupt domains using "interrupts" property
in the node as this bypassed the hierarchical setup and messed up the
irq chaining.

In preparation for removal of static setup of IRQ resource from DT core
code use platform_get_irq().

drm/exynos: drop the use of label from exynos_dsi_register_te_irq

2021-12-22T02:39:39+00:00

Dropped the use of 'out' label from exynos_dsi_register_te_irq function
because the label isn't needed. This patch returns an error in each
error case directly not going to 'out' label.

With this patch build warning[1] is also fixed, which was reported by
kernel test robot

drm/exynos: Implement mmap as GEM object function

2021-12-22T02:39:39+00:00

Moving the driver-specific mmap code into a GEM object function allows
for using DRM helpers for various mmap callbacks.

The respective exynos functions are being removed. The file_operations
structure exynos_drm_driver_fops is now being created by the helper macro
DEFINE_DRM_GEM_FOPS().
