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 Signed-off-by: Vishwanath BS <Vishwanath.bs@ti.com> [paul@pwsan.com: fixed whitespace] Signed-off-by: Paul Walmsley <paul@pwsan.com> |
