This driver supports the MIPI DSI encoder found in the RZ/G2L SoC. It currently supports DSI mode only. Signed-off-by: Biju Das <biju.das.jz@bp.renesas.com>

The RZ/G2L MIPI DSI TX is embedded in the Renesas RZ/G2L family SoC's. It can operate in DSI mode, with up to four data lanes. Signed-off-by: Biju Das <biju.das.jz@bp.renesas.com>

The RZ/G2L VSPD provides a single VSPD instance. it has the following sub modules MAU, CTU, RPF, DPR, LUT, BRS, WPF and LIF. It does not have version register, so added a new compatible string to match to get the version value. Also the reset is shared with DU module. Signed-off-by: Biju Das <biju.das.jz@bp.renesas.com>

…indings Document VSPD found in RZ/G2L and RZ/V2L family SoC's. Signed-off-by: Biju Das <biju.das.jz@bp.renesas.com>

The LCD controller is composed of Frame Compression Processor (FCPVD), Video Signal Processor (VSPD), and Display Unit (DU). It has DPI/DSI interfaces and supports a maximum resolution of 1080p along with 2 rpf's to support blending of two picture layers and raster operations (ROPs). A feature bit for RZ/G2L SoC is introduced to support RZ/G2L with the rest of the SoC supported by this driver. Signed-off-by: Biju Das <biju.das.jz@bp.renesas.com>

R-Car has supports DU groups in DU HW, where as it is not supported in RZ/G2L. Add RCAR_DU_FEATURE_GROUP feature bit to support RZ/G2L. Signed-off-by: Biju Das <biju.das.jz@bp.renesas.com>

RZ/G2L LCDC does not have DU plane registers. This patch supports DU planes only for the SoC's with plane feature bit is set. Signed-off-by: Biju Das <biju.das.jz@bp.renesas.com>

DU plane registers are available on R-Car, but it is not present on RZ/G2L. Add RCAR_DU_FEATURE_PLANE feature bit to support later SoC. Signed-off-by: Biju Das <biju.das.jz@bp.renesas.com>

There are some differences related to max frame size supported by different R-Car/RZ-G family of SoC's Max frame size supported by R-Car Gen1 & R-Car Gen2 is 4095x2047 Max frame size supported by R-Car Gen3 is 8190x8190 Max frame size supported by RZ/G2L is 1920x1080 Add max_width and max_height to struct rcar_du_device_info to support later SoC without any code changes. Signed-off-by: Biju Das <biju.das.jz@bp.renesas.com>

Number of RPF's VSP is different on R-Car and RZ/G2L R-Car Gen3 -> 5 RPF's R-Car Gen2 -> 4 RPF's RZ/G2L -> 2 RPF's Add num_rpf to struct rcar_du_device_info to support later SoC without any code changes. Signed-off-by: Biju Das <biju.das.jz@bp.renesas.com>

Increase buff size for compatible variable to avoid stack corruption with RZ/G2L SoC's(renesas,du-r9a07g044l) which requires a buff size more than the current allocated size. Signed-off-by: Biju Das <biju.das.jz@bp.renesas.com>

Add DSI clock and reset entries to CPG driver. Signed-off-by: Biju Das <biju.das.jz@bp.renesas.com>

Add LCDC clock and reset entries to CPG driver. Signed-off-by: Biju Das <biju.das.jz@bp.renesas.com>

Add support for M4 clock which is sourced from pll2_533_div2. Signed-off-by: Biju Das <biju.das.jz@bp.renesas.com>

Add support for M3 clock which is sourced from DSI divider connected to PLL5_4 mux. Signed-off-by: Biju Das <biju.das.jz@bp.renesas.com>

Add support for {M2, M2_DIV2} clocks which is sourced from pll3_533. Signed-off-by: Biju Das <biju.das.jz@bp.renesas.com>

Add support for M1 clock which is sourced from FOUTPOSTDIV. Signed-off-by: Biju Das <biju.das.jz@bp.renesas.com>

M3 clock is sourced from DSI Dividers(DSIDIVA and DSIDIVB) This patch uses the LUT to set the divider values for DSI/DPI mode on various frequencies defined in LUT. Signed-off-by: Biju Das <biju.das.jz@bp.renesas.com>

Add PLL5_4 clk mux support to select clock from different clock sources FOUTPOSTDIV and FOUT1PH0. This patch uses the LUT to select the source based on DSI/DPI mode and frequencies. Signed-off-by: Biju Das <biju.das.jz@bp.renesas.com>

PLL5 generates FOUTPOSTDIV clk and is sourced by LCDC/DSI modules. The FOUTPOSTDIV is connected to PLL5_4 MUX. Video clock is sourced from DSI divider which is connected to PLL5_4 MUX. Added 2 LUT's for generating FOUTPOSTDIV, 1 for DSI mode and other for DPI mode as it requires different parameters for generating the video clock. The LUT supports minimal set of frequency used by commonly used resolutions. This patch uses the above LUT to generate the required video clock by matching the frequency value in LUT with FOUTPOSTDIV/DSI_DIV. Signed-off-by: Biju Das <biju.das.jz@bp.renesas.com>

There is only a single instance of frontswap ops in the kernel, so simplify the frontswap code by removing support for multiple operations.

Given that frontswap_register_ops must be called from built-in code, there is no need to handle the case of swapfiles coming online before or during it, so delete the code that deals with that case.
