    OMAP3 clock: add support for 192Mhz DPLL4M2 output · 7356f0b2
    Vishwanath BS authored
    In 3630, DPLL4M2 output can be 96MHz or 192MHz (for SGX to run at
    192). This patch has changes to support this feature. 96MHz clock is
    generated by dividing 192Mhz clock by 2 using CM_CLKSEL_CORE register.
    SGX can select Core Clock, 192MHz clock or CM_96M_FCLK as it's
    functional clock. In summary changes done are:
    1. Added a feature called omap3_has_192mhz_clk and enabled for 3630
    2. Added a new clock node called omap_192m_alwon_ck
    3. Made omap_96m_alwon_fck to derive its clock from omap_192m_alwon_ck
