The for-loop iterates with a u8 loop counter i and compares this with the loop upper limit of num_parents that is an int type. There is a potential infinite loop if num_parents is larger than the u8 loop counter. Fix this by making the loop counter the same type as num_parents. Also make num_parents an unsigned int to match the return type of the call to clk_hw_get_num_parents.

If there is a IOCTL_SET_PLL_FRAC_MODE request sent to ATF ever, we shouldn't skip invoking PM_CLOCK_ENABLE fn even though this pll has been enabled. In ATF implementation, it will only assign the mode to the variable (struct pm_pll *)pll->mode when handling IOCTL_SET_PLL_FRAC_MODE call. Invoking PM_CLOCK_ENABLE can force ATF send request to PWU to set the pll mode to PLL's register. There is a scenario that happens in enabling VPLL_INT(clk_id:96): 1) VPLL_INT has been enabled during booting. 2) A driver calls clk_set_rate and according to the rate, the VPLL_INT should be set to FRAC mode. Then zynqmp_pll_set_mode is called to pass IOCTL_SET_PLL_FRAC_MODE to ATF. Note that at this point ATF just stores the mode to a variable. 3) This driver calls clk_prepare_enable and zynqmp_pll_enable is called to try to enable VPLL_INT pll. Because of 1), the function zynqmp_pll_enable just returns without doing anything after checking that this pll has been enabled. In the scenario above, the pll mode of VPLL_INT will never be set successfully. So adding set_pll_mode to check condition to fix it.

The round_rate callback should only perform rate calculation and not involve calling zynqmp_pll_set_mode to change the pll mode. So let's move zynqmp_pll_set_mode out of round_rate and to set_rate callback. Fixes: 3fde0e16 ("drivers: clk: Add ZynqMP clock driver") Reported-by:
