Signed-off-by: Cong Dang Signed-off-by: Geert Uytterhoeven --- Changes compared to the BSP: - Merge two patches, - Fix whitespace in Makefile, - Rename VIOSCR/VCSCR to VIOSRC/VCSRC, - Rename "zN" to "zcN" to match documentation, - Change register bitfield offsets for zc[1-3] from 0 to actual values, - Change parent of IMPBSRC/VIOSRC/VCSRC from PLL1_DIV2 to PLL1, - Add missing SD0H clock, - Change parent of SD0 from SDSRC to SD0H, - Fix No newline at end of file. --- drivers/clk/renesas/Kconfig | 5 + drivers/clk/renesas/Makefile | 1 + drivers/clk/renesas/r8a779h0-cpg-mssr.c | 240
