2021-11-10drm/omap: Make use of the helper function devm_platform_ioremap_resourcexxx()Cai Huoqing1-3/+1
Use the devm_platform_ioremap_resource_byname() helper instead of calling platform_get_resource_byname() and devm_ioremap_resource() separately Use the devm_platform_ioremap_resource() helper instead of calling platform_get_resource() and devm_ioremap_resource() separately Signed-off-by: Cai Huoqing <caihuoqing@baidu.com> Reviewed-by: Tomi Valkeinen <tomi.valkeinen@ideasonboard.com> Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ideasonboard.com> Link: https://patchwork.freedesktop.org/patch/msgid/20210831135707.4676-1-caihuoqing@baidu.com
2020-11-10drm: omapdrm: Replace HTTP links with HTTPS onesAlexander A. Klimov1-1/+1
Rationale: Reduces attack surface on kernel devs opening the links for MITM as HTTPS traffic is much harder to manipulate. Deterministic algorithm: For each file: If not .svg: For each line: If doesn't contain `\bxmlns\b`: For each link, `\bhttp://[^# \t\r\n]*(?:\w|/)`: If neither `\bgnu\.org/license`, nor `\bmozilla\.org/MPL\b`: If both the HTTP and HTTPS versions return 200 OK and serve the same content: Replace HTTP with HTTPS.

2018-03-01drm: omapdrm: dss: Store the registered plls array in struct dss_deviceLaurent Pinchart1-2/+1
As part of an effort to remove the usage of global variables in the driver, store the registered plls array in the dss_device structure instead of a global variable.

2018-03-01drm: omapdrm: dss: Pass PLL pointer to dss_ctrl_pll_enable()Laurent Pinchart1-2/+2
This will allow accessing the PLL data to get the DSS device pointer, removing the need to access the global DSS private data. Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Reviewed-by: Sebastian Reichel <sebastian.reichel@collabora.co.uk>
2018-03-01drm: omapdrm: dss: Pass DSS private structure to runtime PM functionsLaurent Pinchart1-4/+6
To prepare for the removal of the global variable storing DSS private data, pass its pointer to the dss_runtime_{get,put}() functions. As this requires getting hold of the dss_device structure in the callers, we add a new dss_get_device() function to retrieve it. The function currently returns a pointer to the global data structure, and will later be updated to get the pointer from device driver data when the DSS private structure will be allocated dynamically.

2017-12-19drm: omapdrm: Remove filename from header and fix copyright tagAndrew F. Davis1-1/+1
Having the filename in the header serves little purpose and is often wrong after renames as it is here in several places, just drop it from all omapdrm files. While we are here unify the copyright tags to the TI recommended style. Signed-off-by: Andrew F. Davis <afd@ti.com>
2017-08-16drm: omapdrm: hdmi: Configure the PLL from the HDMI core versionLaurent Pinchart1-13/+2
The OMAP4 and OMAP5 PLLs have different properties that require specific handling in the HDMI PLL driver. This needs knowledge of the PLL version, which is currently inferred from the DSS version. AS part of the effort to remove usage of the DSS version, use the HDMI controller version instead.

2017-08-16drm: omapdrm: hdmi: Rename functions and structures to use hdmi_ prefixLaurent Pinchart1-4/+5
The dsi_pll_ops structure and dsi_init_pll_data() function incorrectly use a dsi_ prefix, likely due to copy & paste. Fix it by using the correct hdmi_ prefix. Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>
2017-06-02drm: omapdrm: Remove duplicate error messages when mapping memoryLaurent Pinchart1-8/+1
The devm_ioremap_resource() call can handle being given a NULL resource, and prints an error message when mapping fails. Switch the remaining devm_ioremap() calls to devm_ioremap_resource() and remove all extraneous resource NULL checks and error messages printed manually by the driver.

2016-06-07Merge omapdss header refactoringTomi Valkeinen1-2/+1
Merge omapdss public header refactoring, which separates the public header into omapdrm and omapfb parts.
2016-06-06Merge branch '4.8/omapdrm-pll' (omapdrm PLL work)Tomi Valkeinen1-61/+14
Merge omapdrm PLL work, which makes it possible to use the DSS PLLs in a versatile manner, for example, HDMI PLL can be used for LCDs.

2016-05-31drm/omap: include linux/seq_file.h where neededArnd Bergmann1-0/+1
The omapdrm driver relies on this header to be included implicitly, but this does not always work, and I get this error in randconfig builds: gpu/drm/omapdrm/dss/hdmi_phy.c: In function 'hdmi_phy_dump': gpu/drm/omapdrm/dss/hdmi_phy.c:34:2: error: implicit declaration of function 'seq_printf' [-Werror=implicit-function-declaration] gpu/drm/omapdrm/dss/hdmi_wp.c: In function 'hdmi_wp_dump': gpu/drm/omapdrm/dss/hdmi_wp.c:26:2: error: implicit declaration of function 'seq_printf' [-Werror=implicit-function-declaration] gpu/drm/omapdrm/dss/hdmi_pll.c: In function 'hdmi_pll_dump': gpu/drm/omapdrm/dss/hdmi_pll.c:30:2: error: implicit declaration of function 'seq_printf' [-Werror=implicit-function-declaration] This adds the #include statements in all files that have a seq_printf statement.

2016-05-19drm/omap: HDMI PLL: use runtime pmTomi Valkeinen1-0/+9
To make it possible to use HDMI PLL for other video outputs than HDMI, the HDMI PLL code needs to do runtime_get/put for the HDMI IP, so that the IP (include the PLL) is enabled. To do that we also need to store the HDMI pdev in the hdmi_pll_data. Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>
2016-05-19drm/omap: add field for PLL typeTomi Valkeinen1-0/+4
DSS uses two types of PLLs, type A (DSI & Video) and type B (HDMI). The two types behave slightly differently, but we don't have the type of the PLL available anywhere for the driver. This patch adds an enum for the PLL type and a field in the PLL's HW data to store it. Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>

2015-12-29drm/omap: move omapdss & displays under omapdrmTomi Valkeinen1-0/+255
Now that omapfb has its own copy of omapdss and display drivers, we can move omapdss and display drivers which omapdrm uses to omapdrm's directory. We also need to change the main drm Makefile so that omapdrm directory is always entered, because omapdss has a file that can't be built as a module.
