OMAPDSS: remove uses of init/exit

2015-06-17T10:44:47Z

The following patches will add component handling to omapdss, improving the handling of deferred probing. However, at the moment we're using quite a lot of __inits and __exits in the driver, which prevent normal dynamic probing and removal. This patch removes most of the uses of __init and __exit, so that we can register drivers after module init, and so that we can unregister drivers even if the module is built-in.

OMAPDSS: Add Video PLLs for DRA7xx

2015-02-04T10:32:05Z

DRA7xx SoCs have one (DRA72x) or two (DRA74x) video PLLs. They are basically the same as DSI PLLs on OMAPs, but without the rest of the DSI hardware. The video PLLs also require some configuration via the CONTROL module. Signed-off-by: Tomi Valkeinen

OMAPDSS: Add functions for external control of PLL

2015-02-04T10:32:05Z

Add functions which configure the control module register CTRL_CORE_DSS_PLL_CONTROL found in DRA7xx SoCs. This register configures whether the PLL registers are accessed internally by DSS, or externally using OCP2SCP interface. They also configure muxes which route the PLL output to a particular LCD overlay manager within DSS. Signed-off-by: Tomi Valkeinen

OMAPDSS: DSS: Add DRA7xx base support

2015-02-04T10:32:05Z

Add base support for DRA7xx to DSS core. Signed-off-by: Tomi Valkeinen

OMAPDSS: PLL: add dss_pll_wait_reset_done()

2015-02-04T10:32:03Z

Add a helper function to wait until the PLL's reset is done. Signed-off-by: Tomi Valkeinen

OMAPDSS: Add enum dss_pll_id

2015-02-04T10:32:02Z

In some cases we need global identifiers for the DSS PLLs, for example when configuring clock muxing on DRA7. For this purpose let's add a 'enum dss_pll_id'. Signed-off-by: Tomi Valkeinen

OMAPDSS: DSI: use common DSS PLL support

2014-11-12T11:40:24Z

Now that we have the common DSS PLL support, change DSI to use it. This results in quite a lot of changes, but almost all of them are trivial name changes. The functions to calculate and program the PLL settings can be removed from dsi.c, as the common PLL API contains the same functionality. We also need to create struct dss_pll_hw entries for PLL hardware features for different OMAP platforms, instead of using the dss_features.c as the old code does. Signed-off-by: Tomi Valkeinen

OMAPDSS: Add common PLL code

2014-11-12T11:40:23Z

OMAP DSS currently contains two different PLLs: DSI PLL (Type A PLL) and HDMI PLL (Type B PLL). When DRA7 support is added, we will also support Video PLLs (Type A). The driver currently handles all PLLs totally separately. This patch adds common DSS PLL code, which a) lets us have common code for the PLLs b) lets the users of the PLLs use a common API, instead of DSI API or HDMI API. Signed-off-by: Tomi Valkeinen

OMAPDSS: DSI: dsi_runtime_get/put in pll_init

2014-11-12T11:40:23Z

When DPI uses the DSI PLL for pixel clock, the DPI code will call dsi_runtime_get/put to keep the DSI block enabled. A much simpler way to handle this is to do dsi_runtime_get/put in DSI's dsi_pll_init() and dsi_pll_uninit(), thus removing the need for DSI to call the runtime PM functions.

OMAPDSS: DSI: turn hsdivs fields to arrays

2014-11-12T11:40:22Z

We are creating a common DSS PLL code, so having fixed DSI specific hsdiv fields in the clock information is not ok. This patch changes the hsdiv fields to arrays, so that we can use all the 4 possible hsdiv outputs (DSI only usees 2), and we have generic way to access the hsdivs. Signed-off-by: Tomi Valkeinen
