This should make the code easier to read and understand. This does change the code behavior slightly. The clock mux PMCR register setting now depends solely on the DT properties which configure the clock mux between external clock and internal RCC generated clock. The mux PMCR register settings no longer depend on the supplied clock frequency, that supplied clock frequency is now only validated, and if the clock frequency is invalid for a mode, it is rejected. Previously, the code would switch the PMCR register clock mux to internal RCC generated clock if external clock couldn't provide suitable frequency, without checking whether the RCC generated clock frequency is correct. Such behavior is risky at best, user should have configured their clock correctly in the first place, so this behavior is removed here.

This should make the code easier to read and understand. The dwmac->enable_eth_ck variable in the end indicates whether the MAC clock are supplied by external oscillator (true) or internal RCC clock IP (false). The dwmac->enable_eth_ck value is set based on multiple DT properties, some of them deprecated, some of them specific to bus mode. The following DT properties and variables are taken into account. In each case, if the property is present or true, MAC clock is supplied by external oscillator. - "st,ext-phyclk", assigned to variable dwmac->ext_phyclk - Used in any mode (MII/RMII/GMII/RGMII) - The only non-deprecated DT property of the three - "st,eth-clk-sel", assigned to variable dwmac->eth_clk_sel_reg - Valid only in GMII/RGMII mode - Deprecated property, backward compatibility only - "st,eth-ref-clk-sel", assigned to variable dwmac->eth_ref_clk_sel_reg - Valid only in RMII mode - Deprecated property, backward compatibility only The stm32mp1_select_ethck_external() function handles the aforementioned DT properties and sets dwmac->enable_eth_ck accordingly. The stm32mp1_set_mode() is adjusted to call stm32mp1_select_ethck_external() first and then only use dwmac->enable_eth_ck to determine hardware clock mux settings. No functional change intended.
