The DSI PLL parameters (regm, regn, regm_dispc, regm_dsi, fint) have different fields and also different Max values on OMAP3 and OMAP4. Use dss features to calculate the register fields and min/max values based on current OMAP revision.

Create 2 functions dss_feat_get_param_min() and dss_feat_get_param_max() which return the minimum and maximum value of a parameter. Introduce a enum in dss_features called dss_range_param which contains parameters whose ranges we are interested in. Replace this with dss_feat_get_max_dss_fck() which is specific to the parameter DSS_FCK. Signed-off-by: NArchit Taneja <archit@ti.com> Signed-off-by: NTomi Valkeinen <tomi.valkeinen@ti.com>

The structures dss_reg_field and dss_clk_source_name have enum members which specify the register field and the clock source respectively. These members are not used to choose the correct result in the corresponding feature functions. Remove these members and change the features array declaration to incorporate these enums. The structure dss_clk_source_name without the enum member is just a pointer to an string. Remove the structure and use a character pointer directly.

On OMAP3, the pixel clock for the LCD manager was derived through DISPC_FCLK as: Lcd Pixel clock = DISPC_FCLK / lcd / pcd Where lcd and pcd are divisors in the DISPC_DIVISOR register. On OMAP4, the pixel clocks for LCD1 and LCD2 managers are derived from 2 new clocks named LCD1_CLK and LCD2_CLK. The pixel clocks are calculated as: Lcd_o Pixel clock = LCDo_CLK / lcdo /pcdo, o = 1, 2 Where lcdo and pcdo registers are divisors in DISPC_DIVISORo registers. LCD1_CLK and LCD2_CLK can have DSS_FCLK, and the M4 divider clocks of DSI1 PLL and DSI2 PLL as clock sources respectively. Introduce functions to select and get the clock source for these new clocks. Modify DISPC functions get the correct lck and pck rates based on the clock source of these clocks. Since OMAP2/3 don't have these clocks, force OMAP2/3 to always have the LCD_CLK source as DSS_CLK_SRC_FCK by introducing a dss feature. Introduce clock source names for OMAP4 and some register field changes in DSS_CTRL on OMAP4. Currently, LCD2_CLK can only have DSS_FCLK as its clock source as DSI2 PLL functionality hasn't been introduced yet. BUG for now if DSI2 PLL is selected as clock.

Using dss_features to select independent core clock divider and setting it. Added the register used, to DISPC context save and restore group ----------------------------------------------------------------------- In OMAP4, the minimum DISPC_CORE_CLK required can be expressed as: DISPC_CORE_CLK >= max(PCLK1*HSCALE1, PCLK2*HSCALE2, ...) Where PCLKi is the pixel clock generated by MANAGERi and HSCALEi is the maximum horizontal downscaling done through MANAGERi Based on the usecase, core clk can be increased or decreased at runtime to save power. Such mechanism are not yet implemented. Hence, we set the core clock divisor to 1, to support maximum range of resolutions ------------------------------------------------------------------------ Signed-off-by: NRaghuveer Murthy <raghuveer.murthy@ti.com> Signed-off-by: NTomi Valkeinen <tomi.valkeinen@ti.com>

The OMAP4 DISPC_DIVISOR1 is backward compatible to OMAP3xxx DISPC_DIVISOR. However DISPC_DIVISOR is also provided in OMAP4, to control DISPC_CORE_CLK independent of Primary and Secondary display clocks. Renamed DISPC_DIVISOR(ch) to DISPC_DIVISORo(ch), to facilitate introduction of DISPC_DIVISOR register, which is specific for OMAP4. OMAP4 has 3 registers DISPC_DIVISOR, DISPC_DIVISOR1 and DISPC_DIVISOR2. Also updated, all the usages of DISPC_DIVISOR(ch) to DISPC_DIVISORo(ch). Use DISPC_DIVISORo(ch) when DISPC_DIVISOR1 or DISPC_DIVISOR2 has to be configured OMAP4 TRM uses DISPC_DIVISORo generically to refer to DISPC_DIVISOR1 and DISPC_DIVISOR2 Signed-off-by: NRaghuveer Murthy <raghuveer.murthy@ti.com> Signed-off-by: NTomi Valkeinen <tomi.valkeinen@ti.com>

In OMAP3xxx DISPC_DIVISOR register has a logical clock divisor (lcd_div) field. The lcd_div is common, for deciding the DISPC core functional clock frequency, and the final pixel clock frequency for LCD display. In OMAP4, there are 2 LCD channels, hence two divisor registers, DISPC_DIVISOR1 and DISPC_DIVISOR2. Also, there is a third register DISPC_DIVISOR. The DISPC_DIVISOR in OMAP4 is used to configure lcd_div exclusively for core functional clock configuration. For pixel clock configuration of primary and secondary LCDs, lcd_div of DISPC_DIVISOR1 and DISPC_DIVISOR2 are used respectively Signed-off-by: NArchit Taneja <archit@ti.com> Signed-off-by: NRaghuveer Murthy <raghuveer.murthy@ti.com> Signed-off-by: NTomi Valkeinen <tomi.valkeinen@ti.com>

When using OMAP2_DSS_USE_DSI_PLL, which selects DSI PLL as source clock for DISPC, the DSI needs the vdds_dsi regulator. Latest regulator changes broke this, causing the the code to not acquire the regulator when using OMAP2_DSS_USE_DSI_PLL. This patch acquires the vdds_dsi regulator in dsi_pll_init(), fixing the issue. This is is just a quick hack to get the OMAP2_DSS_USE_DSI_PLL option working. There shouldn't be any other downside in this solution than some extra lines of code. OMAP2_DSS_USE_DSI_PLL is itself a big hack, and should be removed, and the feature itself should be implemented in a more sane way. However, the solution is not trivial, and people are using DSI PLL to get more exact pixel clocks, so this hack is an acceptable temporary solution for the time being.

Taal driver used to take a hard coded Macro for Virtual Channel and the VC_ID. The Taal panel driver now requests for a Virtual channel through the omap_dsi_request_vc() call in taal_probe(). The channel number returned by the request_vc() call is used for sending command and data to the Panel. The DSI driver automatically configures the Virtual Channel's source to either Video Port or L4 Slave port based on what the panel driver is using it for. The driver uses omap_dsi_release_vc() to free the VC specified by the panel. taal_remove() or when a request_vc() call fails.

Introduce functions which request and release VC's. This will be used in panel drivers in their probes. omap_dsi_request_vc() takes in the pointer to the omap_dss_device, the VC_ID parameter which goes into the header of the DSI packets, and returns a Virtual channel number (or virtual channel register set) which it can use. omap_dsi_set_vc_id() takes the omap_dss_device pointer, the Virtual Channel number and the VC_ID that needs to be set for the specifed Virtual Channel. omap_dsi_release_vc() takes the omap_dss_device pointer and the Virtual Channel number that needs to be made free.
