Another difference is that the new SoCs do not have a clock divider inside. Instead of this we should configure sample mode depending on input clock rate. The pin assignment is also different: the H6 uses PC0, the R528/T113 PC4 instead. This makes for a change in spi0_pinmux_setup() routine. This patch extends the H6/H616 #ifdef guards to also cover the R528/T113, using the shared CONFIG_SUNXI_GEN_NCAT2 and CONFIG_MACH_SUN8I_R528 symbols. Also use CONFIG_SUNXI_GEN_NCAT2 symbol for the Kconfig dependency.

The main difference is that new SoCs don't have a clock divider (SPI_CCR register) inside SPI IP. Instead SPI sample mode should be configured depending on the input clock. For now SPI input clock source selection is not supported by this driver, and only HOSC@24MHz can be used as input clock. Therefore, according to the, manual we could change the SPI sample mode from delay half cycle(default) to normal.
