clk: imx: Select MXC_CLK for i.MX93 clock driver

2022-03-15T21:44:46+00:00

Most of the i.MX clock generic API is built by selecting MXC_CLK. Without it, the i.MX93 clock driver will fail to build: aarch64-linux-gnu-ld: drivers/clk/imx/clk-imx93.o: in function `imx93_clocks_probe': clk-imx93.c:(.text+0xa8): undefined reference to `imx_obtain_fixed_clk_hw' So fix this by selecting MXC_CLK for the CLK_IMX93.

clk: imx: pll14xx: Support dynamic rates

2022-03-04T15:06:30+00:00

The pll1443x PLL so far only supports rates from a rate table passed during initialization. Calculating PLL settings dynamically helps audio applications to get their desired rates, so support for this is added in this patch. The strategy to get to the PLL setting for a rate is: - First try to only adjust kdiv which specifies the fractional part of the PLL. This setting can be changed without glitches on the output and is therefore preferred - When that isn't possible then the rate table is searched for suitable rates, so for standard rates the same settings are used as without this patch - As a last resort the best settings are calculated dynamically The code in this patch is based on patches from Adrian Alonso and Mads Bligaard Nielsen Signed-off-by: Sascha Hauer Reviewed-by: Abel Vesa Link: https://lore.kernel.org/r/20220304125256.2125023-9-s.hauer@pengutronix.de Signed-off-by: Abel Vesa
