[PATCH v2 2/2] clk: renesas: r9a07g044: Add CRU_SYSCLK and CRU_VCLK to no PM list

From: Prabhakar
Date: Tue Oct 25 2022 - 21:42:52 EST


From: Lad Prabhakar <prabhakar.mahadev-lad.rj@xxxxxxxxxxxxxx>

CRU_SYSCLK and CRU_VCLK clocks need to be turned ON/OFF in particular
sequence for the CRU block hence add these clocks to
r9a07g044_no_pm_mod_clks[] array.
