NACK: Bit 10 is MSP1

        clk = clk_reg_prcc_kclk("p1_i2c4_kclk", "i2cclk",
                        clkrst1_base, BIT(9), CLK_SET_RATE_GATE);
        clk_register_clkdev(clk, NULL, "nmk-i2c.4");
        PRCC_KCLK_STORE(clk, 1, 9);
 
        clk = clk_reg_prcc_kclk("p1_msp3_kclk", "msp1clk",
                        clkrst1_base, BIT(10), CLK_SET_RATE_GATE);
        clk_register_clkdev(clk, NULL, "msp3");
        clk_register_clkdev(clk, NULL, "ux500-msp-i2s.3");
        PRCC_KCLK_STORE(clk, 1, 10);
