From: Lad Prabhakar <prabhakar.mahadev-lad.rj@xxxxxxxxxxxxxx> Hi All, This patch series adds DU/DSI clocks and provides support for the MIPI DSI interface on the RZ/V2H(P) SoC. It was originally part of series [0], but has now been split into 4 patches due to dependencies on the clock driver, making it easier to review and merge. [0] https://lore.kernel.org/all/20250430204112.342123-1-prabhakar.mahadev-lad.rj@xxxxxxxxxxxxxx/ Note: This patch series applies on top of the following patch series: [1] https://lore.kernel.org/all/20250530165906.411144-1-prabhakar.mahadev-lad.rj@xxxxxxxxxxxxxx/ v5-> v6: - Renamed CPG_PLL_STBY_SSCGEN_WEN to CPG_PLL_STBY_SSC_EN_WEN - Updated CPG_PLL_CLK1_DIV_K, CPG_PLL_CLK1_DIV_M, and CPG_PLL_CLK1_DIV_P macros to use GENMASK - Updated req->rate in rzv2h_cpg_plldsi_div_determine_rate() - Dropped the cast in rzv2h_cpg_plldsi_div_set_rate() - Dropped rzv2h_cpg_plldsi_round_rate() and implemented rzv2h_cpg_plldsi_determine_rate() instead - Made use of FIELD_PREP() - Moved CPG_CSDIV1 macro in patch 2/4 - Dropped two_pow_s in rzv2h_dsi_get_pll_parameters_values() - Used mul_u32_u32() while calculating output_m and output_k_range - Used div_s64() instead of div64_s64() while calculating pll_k - Used mul_u32_u32() while calculating fvco and fvco checks - Rounded the final output using DIV_U64_ROUND_CLOSEST() - Renamed CLK_DIV_PLLETH_LPCLK to CLK_CDIV4_PLLETH_LPCLK - Renamed CLK_CSDIV_PLLETH_LPCLK to CLK_PLLETH_LPCLK_GEAR - Renamed CLK_PLLDSI_SDIV2 to CLK_PLLDSI_GEAR - Renamed plldsi_sdiv2 to plldsi_gear - Preserved the sort order (by part number). - Added reviewed tag from Geert. - Made use of GENMASK() macro for PLLCLKSET0R_PLL_*, PHYTCLKSETR_* and PHYTHSSETR_* macros. - Replaced 10000000UL with 10 * MEGA - Renamed mode_freq_hz to mode_freq_khz in rzv2h_dsi_mode_calc - Replaced `i -= 1;` with `i--;` - Renamed RZV2H_MIPI_DPHY_FOUT_MIN_IN_MEGA to RZV2H_MIPI_DPHY_FOUT_MIN_IN_MHZ and RZV2H_MIPI_DPHY_FOUT_MAX_IN_MEGA to RZV2H_MIPI_DPHY_FOUT_MAX_IN_MHZ.
