drm/sti: load HQVDP firmware the first time HQVDP's plane is used

2015-11-03T12:04:56+00:00

The way to load the HQVDP firmware has been updated. HQVDP firmware is now loaded the first time an HQVDP plane is used and no more when the HQVDP driver is bound. This solves the dependency we had on the file system availability. The first time the HQVDP plane is used, we are sure that file system is available so request_firmware function will match. CONFIG_FW_LOADER_USER_HELPER_FALLBACK is then no more mandatory. Cc: Takashi Iwai Signed-off-by: Vincent Abriou

drm/sti: Remove local fbdev emulation Kconfig option

2015-11-03T12:04:55+00:00

DRM_STI_FBDEV config is currently used to enable/disable fbdev emulation for the sti kms driver. Remove this local config option and use the core fb helpers with drm_kms_helper.fbdev_emulation module option to enable/disable fbdev at runtime.

drm/sti: remove redundant sign extensions

2015-11-03T12:04:55+00:00

arg is long int, so arg = (arg << 22) >> 22 makes the upper 22 bits of arg equal to bit 9 (or bit 41). But we then mask away all but bits 0-9, so this is entirely redundant. Signed-off-by: Rasmus Villemoes Reviewed-by: Vincent Abriou

drm/sti: hdmi use of_get_i2c_adapter_by_node interface

2015-11-03T12:04:54+00:00

This change is needed to properly lock I2C bus device and driver, which serve DDC lines. Without this change I2C bus driver module may gone in runtime and this won't be noticed by the driver. Signed-off-by: Vladimir Zapolskiy Reviewed-by: Vincent Abriou

drm/sti: hdmi fix i2c adapter device refcounting

2015-11-03T12:04:54+00:00

The commit 53bdcf5f026c ("drm: sti: fix sub-components bind") moves i2c adapter search and locking from .bind() to .probe(), however proper error path in the modified .probe() is not implemented and leftover of the related error path in .bind() remains. This change fixes these issues. Fixes: 53bdcf5f026c ("drm: sti: fix sub-components bind") Signed-off-by: Vladimir Zapolskiy Reviewed-by: Vincent Abriou

drm/sti: Do not export symbols

2015-11-03T12:04:54+00:00

None of these exported symbols are used outside of the drm-sti driver, so there is no reason to export them. Cc: Benjamin Gaignard Cc: Vincent Abriou Signed-off-by: Thierry Reding Reviewed-by: Vincent Abriou

drm/sti: Build monolithic driver

2015-11-03T12:04:54+00:00

There's no use building the individual drivers as separate modules because they are all only useful if combined into a single DRM/KMS device. Cc: Benjamin Gaignard Cc: Vincent Abriou Signed-off-by: Thierry Reding Reviewed-by: Vincent Abriou
