2017-09-14clk: at91: utmi: Set the reference clock frequencyWenyou Yang
By default, it is assumed that the UTMI clock is generated from a 12 MHz reference clock (MAINCK). If it's not the case, the FREQ field of the SFR_UTMICKTRIM has to be updated to generate the UTMI clock in the proper way. The UTMI clock has a fixed rate of 480 MHz. In fact, there is no multiplier we can configure. The multiplier is managed internally, depending on the reference clock frequency, to achieve the target of 480 MHz. The patch is cloned from the patch of mailing-list: [PATCH v2] clk: at91: utmi: set the mainck rate Signed-off-by: Wenyou Yang <wenyou.yang@microchip.com> [trini: Depend on SPL_DM] Signed-off-by: Tom Rini <trini@konsulko.com>
